The present invention, in some embodiments thereof, relates to compositions and methods for treating and preventing non-malignant respiratory disease (NMRD).
Non-malignant respiratory disease (“NMRD”, also known as non-malignant pulmonary disease or “NMPD”) is a diverse group of acute and chronic conditions affecting the respiratory tract and interfering with gas exchange which constitute a common and significant cause of illness and death worldwide, and make up the vast majority of ICU utilization throughout all hospital systems. Chronic lung disease of some form, including, inter alia, Interstitial Lung Disease (ILD), Bronchiectastis and Chronic Obstructive Pulmonary Disease (COPD), affects greater than 10% of individuals in both highly industrialized and less highly industrialized nations, with chronic obstructive pulmonary disease being the most common.
Chronic respiratory disease is of particular importance in Environmental and Occupational Medicine, with environmental (e.g. pollution) and workplace exposures contributing to the burden of disease across a range of nonmalignant lung conditions in the young, in adults and in the elderly (in addition to the 100% burden for the classic occupational pneumoconioses). This burden has important clinical, research, and policy implications. Current treatment for chronic respiratory disease focuses mostly on palliative care.
According to the World Health Organization (WHO) study, in low-income countries pneumonia leads the top five death causing diseases followed by heart disease, diarrhea, HIV/AIDS and stroke, in high-income countries, pneumonia, and asthma/bronchitis are closing the top five death causing diseases topped only by heart disease, stroke and lung cancer. (see who.int/news/item/27-10-2008-new-study-presents-state-of-the-world-s-health).

The present invention, in some embodiments thereof, relates to compositions and methods for treating and preventing non-malignant respiratory disease (NMRD).
Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details set forth in the following description or exemplified by the Examples. The invention is capable of other embodiments or of being practiced or carried out in various ways.
Non-malignant respiratory disease (NMRD) is a group of acute and chronic conditions affecting the respiratory tract and interfering with gas exchange, exclusive of cancerous and malignant proliferative pulmonary disease. In mild forms (e.g. the common cold, mild bronchitis, pharyngitis, mild allergic respiratory distress), symptoms of NMRD may include coughing, wheezing, pulmonary and/or nasal congestion, copious mucus and mild shortness of breath. Most often, patients with mild NMRD will experience mild to moderate symptoms and recover without requiring special treatment. Moderate to severe cases of NMRD, and particularly in older individuals, those with underlying medical problems and individuals frequently exposed to common triggers of respiratory disease such as particulate pollution (e.g. coal dust, asbestos, silica, etc), dust mites and allergens are more likely to develop into serious, chronic illness, in many cases requiring intensive care with ventilation and life-threatening disease. At this time, there are no specific vaccines or effective preventative treatments for many of the non-malignant respiratory conditions.
Thus, according to an aspect of the invention there is provided a method of preventing or treating a non-malignant respiratory disease or condition (NMRD) in a subject in need thereof, the method comprising administering to the subject an effective amount of a plant species or genus thereof-derived component selected from the group consisting of a plant part, extract thereof, fraction thereof, active ingredient thereof, synthetic analog thereof, mimetic thereof or combination thereof, wherein the component is capable of ameliorating symptoms of NMRD and wherein the plant species is selected from the group consisting of Nigella sativa, Thymus capitatus, Thymus vulgaris, Origanum syriacum, Thymbra spicata, Satujera thymbra, Sesamum indicum, Rhus coriaria, Gynostemma pentaphyllum, Boswellia sacra and Panax ginseng, preventing or treating NMRD in the subject.
According to an alternative or an additional aspect of the invention there is provided a vaccine against a NMRD comprising an effective amount of a plant species or genus thereof-derived component selected from the group consisting of a plant part, extract thereof, fraction thereof, active ingredient thereof, synthetic analog thereof, mimetic thereof or combination thereof, wherein the component is capable of ameliorating symptoms of NMRD and wherein the plant species is selected from the group consisting of Nigella sativa, Thymus capitatus, Thymus vulgaris, Origanum syriacum, Thymbra spicata, Satujera thymbra, Sesamum indicum, Rhus coriaria, Gynostemma pentaphyllum, Boswellia sacra and Panax ginseng.

The term “plant” as used herein encompasses whole plants, a grafted plant, ancestors and progeny of the plants and plant parts, including seeds, flowers, bark, shoots, stems, roots (including tubers), fruit, rootstock, scion, and plant cells, tissues and organs.
According to a specific embodiment, the plant part is a seed.
According to a specific embodiment, the plant part is a fruit.
According to a specific embodiment, the plant part is a leaf.
According to a specific embodiment, the plant part is a stem.
According to a specific embodiment, the plant part is a flower.
The plant part can be a solid part or a non-solid part such as oil or aqueous portions of the plant.
The plant may be in any form including suspension cultures, embryos, meristematic regions, callus tissue, leaves, gametophytes, sporophytes, pollen, and microspores.
The term plant refers to a wild plant or a cultivated variety thereof.
As used herein the term “plant species” refers to a sub-group of one or more plants within the genus. These plants will share similar characteristics with each other. There may be a single plant within a species, or there may be many hundreds of plants. The term intends to include subspecies, such as grown or can be found in different geographical location, e.g., Lebanese Sumac and Syrian Sumac or Korean ginseng and American ginseng.
As used herein “plant genus” refers to a taxonomic rank below family and above species.
It will be appreciated that the relevant species and genera and listed below and each option or combination thereof represents a different embodiment of the invention.
The term “extraction” refers to a separation process which relies on the separation of one or more analytes from the components of a sample other than the one or more analytes. Extractions are processes that typically use two immiscible phases to separate one or more solutes from one phase into the other. The distribution of a solute between two phases is an equilibrium condition described by partition theory. For example, boiling tea leaves in water extracts the tannins, theobromine, and caffeine out of the leaves and into the water. More typical extractions preformed typically but not only in a laboratory are settings of organic compounds out of an aqueous phase and into an organic phase. Common extractants are arranged from ethyl acetate to water (ethyl acetate<acetone<ethanol<methanol<acetone:water (7:3)<ethanol:water (8:2)<methanol:water (8:2)<water) in increasing order of polarity according to the Hildebrand solubility parameter. Procedures for plant extraction are provided in
The term “extract” as used herein refers to the result of such process of separation that can take the form of a solution formulation or other chemical form depending on the extraction process. In particular, the term extract can relate to a substance made by extracting a part of a sample (e.g. a raw material), such as by using a solvent such as ethanol or water. In various instances an extract relates to a solvent that is enriched in one or more solute. In particular, a “plant extract” in the sense of the present disclosure typically comprises a concentrated preparation of a plant material obtained by isolating or purifying desired active constituents with one or more extraction processes.
The choice of the solvent depends on the desired component to be obtained. For example, to extract polar components in an extraction process suggested solvents include, but are not limited to, water, ethanol methanol or butanol while for non polar compounds diethyl ether, hexane or chloroform depending on the use of the extract. For midpolar one may choose Ethyl acetate but other solvents can be used as well.
The general procedure of solid/liquid extraction can be scaled in five different ways:
Maceration: the contact stage is maintained at room temperature.
Decoction or reflux: the contact stage is maintained at the boiling point of the solvent.
Digestion: the contact stage is maintained at a temperature in between those of the previous two cases.
Infusion: the boiling solvent is poured over the solid, then left to cool for a set time.
Leaching or percolation: the solvent passes through the biomass.
It is also possible to combine these methods with each other or with other processes such as distillation, steam distillation, rectification, etc.
According to another embodiment, the use of various solvents, either successively or in combination is contemplated and the ordinary skilled of organic chemistry will know which to choose according to the active ingredient as described below.
Extraction may be further assisted by other means such as ultrafiltration, reverse osmosis, high pressure (supercritical CO2), microwaves, ultrasound, etc.
In some embodiments, the plant part is contacted with a polar solvent (e.g. ethanol) or nonpolar solvent (e.g., hexane or pentane) for several minutes, e.g., 15 minutes or more, about 30 minutes or more, about 1 hour or more, about 2 hours or more, or about 5 hours or more.
Temperature can also be controlled during the contacting.
According to specific embodiments, the plant part is contacted with the solvent (e.g. ethanol) while being constantly mixed e.g. on a shaker.
It will be appreciated that the extraction process can also be solvent-free.
For example, solvent-free microwave extraction (SFME) has been proposed as a green method for the extraction of essential oil from aromatic herbs that are extensively used in the food industry. This technique is a combination of microwave heating and dry distillation performed at atmospheric pressure without any added solvent or water. The isolation and concentration of volatile compounds is performed in a single stage. In some embodiments, SFME and/or hydro-distillation (HD)), are used for the extraction of essential oil from the plants of the invention.
In some embodiments, the process of the present invention comprises isolating a liquid extract (i.e. filtered extract) from the mixture (i.e. crude extract) comprising the liquid extract and solids. Suitable means for isolating the liquid extract (i.e. filtered extract) include those known in the art of organic synthesis and include, but are not limited to, gravity filtration, suction and/or vacuum filtration, centrifuging, setting and decanting, and the like. In some embodiments, the isolating comprises filtering a liquid extract through a porous membrane, syringe, sponge, zeolite, paper, or the like having a pore size of about 1-5 μm, about 0.5-5 μm, about 0.1-5 μm, about 1-2 μm, about 0.5-2 μm, about 0.1-2 μm, about 0.5-1 μm, about 0.1-1 μm, about 0.25-0.45 μm, or about 0.1-0.5 μm (e.g. about 2 μm, about 1 μm, about 0.45 μm, or about 0.25 μm).
According specific embodiments, the present invention contemplates drying (i.e. removal of the polar/non-polar solvent) and/or freezing the filtered extract following generation thereof.
The method for drying the filtered extract (i.e. removing the polar solvent) is not particularly limited, and can include solvent evaporation at a reduced pressure (e.g., sub-atmospheric pressure) and/or an elevated temperature (e.g., above about 25° C.). In some embodiments, it can be difficult to completely remove a solvent from a liquid extract by standard solvent removal procedures such as evaporation. In some embodiments, processes such as co-evaporation, lyophilization, and the like can be used to completely remove the polar solvent from a liquid fraction to form a dry powder, dry pellet, dry granulate, paste, and the like. According to a specific embodiment the polar solvent is evaporated with a vacuum evaporator.
The selection of the extraction process much depends on the component to be isolated.
It will be appreciated that following generation of the extract, specific embodiments of the present invention further contemplate additional purification steps so as to further isolate/purify active agents from the extract, for example, by fractionating the filtered extract.
As used herein “a fraction” refers to a portion of the extract that contains only certain chemical ingredients of the extract but not all.
Fractionating can be performed by processes such as, but not limited to: column chromatography, preparative high performance liquid chromatography (“HPLC”), reduced pressure distillation, and combinations thereof.
According to a specific embodiment, fractionating is performed by HPLC.
In some embodiments, fractionating comprises re-suspending the filtered extract in a polar solvent (such as methanol, as discussed above), applying the polar extract to a separation column, and isolating the extract having the anti-respiratory disease (e.g. anti-fibrotic, anti-inflammatory) activity by column chromatography (preparative HPLC).
An eluting solvent is applied to the separation column with the polar extract to elute fractions from the polar extract. Suitable eluting solvents for use include, but are not limited to, methanol, ethanol, propanol, acetone, acetic acid, carbon dioxide, methylethyl ketone, acetonitrile, butyronitrile, carbon dioxide, ethyl acetate, tetrahydrofuran, di-iso-propylether, ammonia, triethylamine, N,N-dimethylformamide, N,N-dimethylacetamide, and the like, and combinations thereof.
According to an alternative or an additional embodiment, liquid chromatography comprises high performance liquid chromatography (HPLC).
According to an alternative or an additional embodiment, liquid chromatography is performed on a reverse stationary phase.
The fractions may be characterized by analytical methods such as, but not limited to, spectroscopic methods such as, but not limited to, ultraviolet-visible spectroscopy (“UV-Vis”), infrared spectroscopy (“IR”), and the like; mass-spectrometry (“MS”) methods such as, but not limited to, time-of-flight MS; quadrupole MS; electrospray MS, Fourier-transform MS, Matrix-Assisted Laser Desorption/Ionization (“MALDI”), and the like; chromatographic methods such as, but not limited to, gas-chromatography (“GC”), liquid chromatograph (“LC”), high-performance liquid chromatography (“HPLC”), and the like; and combinations thereof (e.g., GC/MS, LC/MS, HPLC/UV-Vis, and the like), and other analytical methods known to persons of ordinary skill in the art.
The component (active ingredients, extract and/or fractions) obtained may be tested for reducing NMRD or symptoms thereof. Exemplary methods for testing the effect are further described herein below as well as in the Examples section which follows.
The active ingredients, extract and/or fraction described herein may be immediately used or stored until further used.
According to specific embodiments, the active ingredients, extract and/or fractions is kept frozen, e.g. in a freezer, until further use (e.g. at about −20° C. to −90° C., at about −70° C. to −90° C., e.g. at −80° C.), for any required length of time.
According to other specific embodiments, the active ingredients, extract and/or fractions is immediately used (e.g. within a few minutes e.g., up to 30 minutes).
The active ingredients, extract and/or fractions may be used separately. Alternatively, different active ingredients, extract and/or fractions (e.g. from different plants or from separate extraction procedures) may be pooled together. Likewise, different active ingredients, extract and/or fractions (from the same extract, from different extracts, from different plants and/or from separate extraction procedures) may be pooled together.
Using the present teachings, the present inventor was able to identify not only plants and extracts that can be used to effectively treat or prevent NMRD, but also active ingredients thereof.
“Active ingredient” refers to a defined chemical composition which is responsible for the anti (preventive or therapeutic) effect against NMRD.
The active ingredient can be purified from a plant or chemically synthesized (artificial, man-made).
Also contemplated herein are analogs and derivatives of the active ingredients as long as the anti (preventive or therapeutic) effect against NMRD is maintained (see e.g., Examples section which follows), which are also referred to as mimetics.
Following are some non-limiting examples for extraction of active ingredients from selected plants of the present invention.
Extraction from leaves of T. capitatus—The Aerial parts of T. capitatus (leaves) samples are collected. Leaves separated from branches are dehydrated at room temperature for 7 days and slightly blended into fine powders for extractions.
Essential oil (EO) extraction—hydro-distillation is used to extract EO from the plant, e.g., dried aerial parts of T. capitatus. In brief, the extraction is conducted for several hours for example, 3 h, by mixing 100 g of plants in 500 mL of distilled water. The extract is dried and concentrated using sodium sulphate and rotatory evaporator under reduced pressure. The EO yield is established by quantity of the obtained oil in mL for 100 g of dried plant. Finally, the pure EO os stored at −4° C. until further analyzed.
Essential oil analysis—The chemical composition of EO is examined by GC and GC-MS. GC analysis is conducted using gas chromatograph. The proportion of the constituents is determined by the integration of peak areas. In addition, mass spectrometry (MS) can be used to analyze the EO typically under the same conditions as described above for gas chromatography. The identification of the different compounds is defined by comparison of their retention indexes (determined relatively to the retention times of a series of n-alkanes) with those of standards of the Wiley library search routines12, based on fit and purity of mass spectra. Such conditions are used for determining the active ingredients as described below.
Extraction from Satujera thymbra:

Chemical Composition of Panax ginseng (ginseng)
Characterization and identification of chemical compounds of ginseng using a variety of methods identified a large variety of compounds in Panax ginseng and classified them as generally being:
According to specific embodiments, the saponin compounds in ginseng and the polysaccharide compounds are the compounds that constitute its phytochemical activity. The most abundant saponin compound in ginseng root was found to be ginsenoside. Polysaccharides from ginseng have been identified as NGP, WGP, 1-KGP, 4-KGP, WGPE and EGP, with WGP and WGPE being the most abundant, depending on the species of ginseng plant material used for extraction.
Most ginseng saponins belong to a family of steroids with a four trans-ring rigid steroid skeleton. They are also referred to as ginsenosides, triterpenoid saponins or dammarane derivatives. More than 200 saponins have been isolated from ginseng plants. In addition to ginseng root, saponins have been identified in ginseng leaves and stems, flower buds, fruits, berries, and seeds. Because steaming or heating changes the saponin profile of ginseng products, ginseng saponins have also been identified in the processed root, leaf, flower-bud and berry.
Ginseng saponins are divided into several groups. Two major groups are the protopanaxadiol (PPD)-type saponins with sugar moieties attached to the C-3 and/or C-20 and the protopanaxatriol (PPT) group with sugar moieties at C-6 and/or at C-20. Other groups include the ocotillol-type with a five-membered epoxy ring at C-20, the oleanane-type with a nonsteroidal structure, and the dammarane type with a modified C-20 side chain. As techniques are developed for chemical purification and structural identification, novel ginseng saponins continue to be discovered.

Chemical Composition of Boswellia Species (Frankincense, Olibanum)
Olibanum, also known as frankincense, is a natural oleo-gum-resin that exudes from tappings in the bark of Boswellia trees. There are approximately 23 species of trees in the genus Boswellia, which grow mainly in Arabia, on the eastern coast of Africa and in India. Characterization and identification of chemical compounds of Olibanum using a variety of methods identified a large variety of compounds in the gum resin of Boswellia tree species and classified them as generally being:
According to specific embodiments, Olibanum comprises 65-85% alcohol-soluble resins, about 5-9% highly aromatic essential oils and the remainder water soluble gums.
In India, the main commercial sources of Boswellia serrata are Andhra Pradesh, Gujarat, Madhya Pradesh, Jharkhand and Chhattisgarh. Regionally, it is also known by different names. The botanical origin and vernacular names of Boswellia serrata are given in below Table 1. Salai, an oleo gum-resin, is a plant exudate of genus Boswellia (Family: Burseraceae). It is tapped from the incision made on the trunk of the tree, which is then stored in specially made bamboo basket. The semi-solid gum-resin is allowed to remain in the basket for about a month during which its fluid content locally known as ‘ras’ keeps flowing out. The residue, semi-solid to solid part, is the gum-resin which hardens slowly into amorphous, tear-shaped products with an aromatic scent. Then, it is broken into small pieces by wooden mallet or chopper and during this process all impurities including bark pieces etc. are removed manually. The gum-resin is then graded according to its flavour, colour, shape and size. Generally four grades i.e. Superfine, Grade I, Grade II and Grade III are available in the market. The fresh gum obtained from the tree is hot with pleasant flavour and slightly bitter in taste. It had been the ‘frankincense’ of ancient Egyptians, Greeks and Romans who used it as prized incense, fumigant as well as a multipurpose aromatic. It is generally used in making incense powder and sticks.

The oleo gum-resins contain 30-60% resin, 5-10% essential oils, which are soluble in the organic solvents, and the rest is made up of polysaccharides (˜65% arabinose, galactose, xylose) which are soluble in water. The resins have a fragrant aroma because of the presence of essential oils and this accounts for their commercial importance.
According to specific embodiments, the common components of Olibanum belonging to the terpene and sesquiterpene families, or their terpenoid derivatives include, but are not limited to α- and β-pinene, α-limonene, myrcene, linalool, α-cubebene, γ-cadinene, β-bourbonene, and α-phellandrene dimer compounds in Olibanum are the compounds that constitute its phytochemical activity. Several oxygenated isoprenoid derivatives have also been identified, such as carbonyl derivatives (e.g., carvone, fenchone) and alcohol-containing terpene and sesquiterpene derivatives (e.g., transpinocarveol, cis-verbenol, and cembrenol), as well as ester-containing compounds (e.g., α-terpinyl acetate and bornyl acetate).
Diverse investigators have reported that limonene is the most abundant volatile in Olibanum, while others have identified octanol acetate, α-pinene and α-thujene as most abundant depending on the species of Boswellia resin used for extraction.
More than 300 essential oils have been isolated from Boswellia ssp.
The table below shows the essential oils recovered from Olibanum extracts prepared by different extraction procedures, from diverse Boswellia ssp.:
Although many Boswellia species produce Olibanum, the major sources of commercial Olibanum are B. serrata (India), B. sacra (Oman), and B carteri (Somalia). The table below shows the major components of Olibanum derived from diverse Boswellia species, according to their percentage representation:

Sesame
Sesame seeds contain thelignans, sesamolin, sesamin, pinoresinol andlariciresinol. Insoluble 11S globulin and soluble 2S albumin, conventionally termed α-globulin and β-globulin, are the two major storage proteins and constitute 80-90% of total seed proteins in sesame. Comparison of amino acid composition indicated that they are substantially less hydrophobic than the known oleosins, and thus should not be aggregated multimers of oleosins. The results of immuno-recognition to sesame proteins reveals that these three polypeptides are unique proteins gathered in oil bodies, accompanying oleosins and triacylglycerols, during the active assembly of the organelles in maturing seeds. The phospholipid, oleic and linoleic acids, chlorophyll and sesamolin, sesamol and γ-tocopherol are found. 10 compounds [2-furfurylthiol, 2-phenylethylthiol, 2-methoxyphenol, 4-hydroxy2, 5-dimethyl-3[2H]-furanone, 2-pentylpyridine, 2-ethyl-3,5-dimethylpyrazine, acetylpyrazine, [E,E]-2,4-decadienal, 2-acetyl-1-pyrroline and 4-vinyl-2-methoxy-phenol] are quantified. On the basis of high OAVs in oil, especially 2-acetyl-1-pyrroline [roasty], 2-furfurylthiol [coffee-like], 2-phenylethylthiol [rubbery] and 4-hydroxy-2,5-dimethyl3[2H]-furanone [caramel-like] are elucidated as important contributors to the overall roasty, sulphury odour of the crushed sesame material. The structures of novel sesaminol glucosides isolated from sesame seed are determined to be sesaminol 2′-O-β-d-glucopyranoside, sesaminol 2′-O-β-d-glucopyranosyl [1→2]-O-β-dglucopyranoside and sesaminol 2′-O-β-d-glucopyranosyl [1»2]-O-[β-d-glucopyransyl [1»6]]-[β-dglucopyranoside.

In some embodiments, NMRD is the result of a primarily pulmonary disease, as in diseases caused by chronic inhalation of silica, anthracite, toxic fumes, asbestos, etc. In other embodiments, NMRD can be a secondary manifestation of pulmonary injury or dysfunction caused by scarring, fibrosis and other effects of non-pulmonary diseases or conditions, such as connective tissue disease (e.g. RA, scleroderma), infectious disease (e.g. polio) or autoimmune disease (SLA).
Individuals suffering from NMRD typically experience coughing, shortness of breath, wheezing, difficulty in breathing, pulmonary or nasal congestion, copious mucus, inflammation of the airways, chest tightness and exercise intolerance. Moderate to severe cases of NMRD, and particularly in older individuals, those with underlying medical problems and individuals frequently exposed to common triggers of respiratory disease such as particulate pollution (e.g. coal dust, asbestos, silica, etc), dust mites and allergens are more likely to develop into serious, chronic illness, in many cases requiring intensive care with ventilation and life-threatening disease.
According to specific embodiments, the NMRD is COPD.
The plant-derived component or components of the present invention can be co-administered with other medications to increase therapeutic bioavailability, boost therapeutic efficacy, and minimize side effects. The plant-derived component or components of the present invention may be administered in a linear or cyclical form, or in any conformation deemed physiologically appropriate as a means of conveying treatment.
In addition to targeted vasodilation, targeted anti-coagulation can be accomplished. For example, in a disease like acute lung injury, which is often marked by pulmonary intra-alveolar coagulation, targeted anti-coagulation can be delivered to the affected pulmonary area by co-administering an effective dose of the plant-derived component or components of the present invention with an anti-coagulant such as tissue factor pathway inhibitor (TFPI) or site-inactivated factor VIIa in a minimal dose to achieve targeted pulmonary anticoagulation with minimal changes in clotting ability over the areas of the body not undergoing thrombosis. Selective pulmonary anti-coagulation can also be utilized to treat other pulmonary diseases marked by pulmonary thrombosis such as pulmonary hypertension, lung transplant rejection and others.
In a disease like chronic obstructive pulmonary disease, which is often marked by shortness of breath, the plant-derived component or components of the present invention can be co-administered to boost the effective concentration and potency of drugs to relax airway smooth muscles such as long lasting beta-2 agonists such as salmeterol or formoterol.
Many pulmonary diseases are often marked by a decrease in glutathione (GSH), a powerful antioxidant. The plant-derived component or components of the present invention can be co-administered with N-Acetylcysteine (NAC), a glutathione precursor, in diseases like pulmonary fibrosis, PAH, ALI, and other pulmonary disorders to boost GSH production and scavenge reactive oxidants often found in pulmonary diseases. GSH may also serve to dampen the inflammatory immune response by binding to triggering receptor expressed on myeloid cells 1 (TREM1) and diminishing monocyte/macrophage- and neutrophil-mediated inflammatory responses. Co-administration of CAR with NAC can serve to lessen the severe inflammatory immune response that often characterizes severe pulmonary and fibrotic diseases like ALI, pulmonary hypertension, autoimmune diseases and many other conditions.
Treatments for pulmonary diseases like pulmonary fibrosis, PAH and ALI can also be improved by co-administering the plant-derived component or components of the present invention with TGF-beta inhibitors like decorin.
In pulmonary hypertension, pulmonary fibrosis and other pulmonary diseases, the benefits of endothelin (ET-1) receptor antagonists, prostacyclin derivatives, phosphodiesterase type 5 inhibitors can be increased for patients through the co-administration with the plant-derived component or components of the present invention.
Other pulmonary and fibrotic disease treatments such as Ketoconazole which inhibits thromboxane and leukotriene synthesis can be improved in its efficacy while minimizing side effects through co-administration with the plant-derived component or components of the present invention.
The term “treating” refers to inhibiting, preventing or arresting the development of a pathology (disease, disorder or condition) and/or causing the reduction, remission, or regression of a pathology. Those of skill in the art will understand that various methodologies and assays can be used to assess the development of a pathology, and similarly, various methodologies and assays may be used to assess the reduction, remission or regression of a pathology.
As used herein, the term “preventing” refers to keeping a disease, disorder or condition from occurring in a subject who may be at risk for the disease, but has not yet been diagnosed as having the disease.
As used herein, the term “subject” includes mammals, preferably human beings, male or female, at any age or gender, who suffer from the pathology. Preferably, this term encompasses individuals who are at risk to develop the pathology (e.g., above 65 of age, exposed to airborne pollutants, particulates, toxic fumes, allergens).
The composition of matter comprising the component(s) (a plant species or genus thereof-derived component selected from the group consisting of a plant part, extract thereof, fraction thereof, active ingredient thereof, synthetic analog thereof, mimetic thereof or combination thereof, wherein said component is capable of ameliorating symptoms of NMRD) of the present invention can be administered to the subject per se, or in a pharmaceutical composition where it is mixed with suitable carriers or excipients.
As used herein a “pharmaceutical composition” refers to a preparation of one or more of the active ingredients described herein with other chemical components such as physiologically suitable carriers and excipients. The purpose of a pharmaceutical composition is to facilitate administration of a compound to an organism.
Herein the term “active ingredient” refers to the composition of matter comprising the components accountable for the biological effect.
Hereinafter, the phrases “physiologically acceptable carrier” and “pharmaceutically acceptable carrier” which may be interchangeably used refer to a carrier or a diluent that does not cause significant irritation to an organism and does not abrogate the biological activity and properties of the administered compound. An adjuvant is included under these phrases.
Herein the term “excipient” refers to an inert substance added to a pharmaceutical composition to further facilitate administration of an active ingredient. Examples, without limitation, of excipients include calcium carbonate, calcium phosphate, various sugars and types of starch, cellulose derivatives, gelatin, vegetable oils and polyethylene glycols.
Techniques for formulation and administration of drugs may be found in “Remington's Pharmaceutical Sciences,” Mack Publishing Co., Easton, PA, latest edition, which is incorporated herein by reference.
Suitable routes of administration may, for example, include oral, rectal, transmucosal, especially transnasal, intestinal or parenteral delivery, including intramuscular, subcutaneous and intramedullary injections as well as intrathecal, direct intraventricular, intracardiac, e.g., into the right or left ventricular cavity, into the common coronary artery, intravenous, intraperitoneal, intranasal, or intrapulmonary or intraocular injections.
In various exemplary embodiments of the invention, the composition is provided as a pharmaceutical or dietary supplement dosage form suitable for oral administration. Dosage forms suitable for oral administration include tablets, soft capsules, hard capsules, pills, granules, powders, emulsions, suspensions, sprays, syrups and pellets. In various other embodiments of the invention, the composition is provided as a pharmaceutical dosage form suitable for parenteral administration such as liquid formulations for administration as drops or by injection, or as solid or semisolid dosage forms for suppositories.
Conventional approaches for drug delivery to the central nervous system (CNS) include: neurosurgical strategies (e.g., intracerebral injection or intracerebroventricular infusion); molecular manipulation of the agent (e.g., production of a chimeric fusion protein that comprises a transport polypeptide that has an affinity for an endothelial cell surface molecule in combination with an agent that is itself incapable of crossing the BBB) in an attempt to exploit one of the endogenous transport pathways of the BBB; pharmacological strategies designed to increase the lipid solubility of an agent (e.g., conjugation of water-soluble agents to lipid or cholesterol carriers); and the transitory disruption of the integrity of the BBB by hyperosmotic disruption (resulting from the infusion of a mannitol solution into the carotid artery or the use of a biologically active agent such as an angiotensin polypeptide). However, each of these strategies has limitations, such as the inherent risks associated with an invasive surgical procedure, a size limitation imposed by a limitation inherent in the endogenous transport systems, potentially undesirable biological side effects associated with the systemic administration of a chimeric molecule comprised of a carrier motif that could be active outside of the CNS, and the possible risk of brain damage within regions of the brain where the BBB is disrupted, which renders it a suboptimal delivery method.
Alternately, one may administer the pharmaceutical composition in a local rather than systemic manner, for example, via injection of the pharmaceutical composition directly into a tissue region of a patient.
Pharmaceutical compositions of some embodiments of the invention may be manufactured by processes well known in the art, e.g., by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping or lyophilizing processes.
Pharmaceutical compositions for use in accordance with some embodiments of the invention thus may be formulated in conventional manner using one or more physiologically acceptable carriers comprising excipients and auxiliaries, which facilitate processing of the active ingredients into preparations which, can be used pharmaceutically. Proper formulation is dependent upon the route of administration chosen.
For injection, the active ingredients of the pharmaceutical composition may be formulated in aqueous solutions, preferably in physiologically compatible buffers such as Hank's solution, Ringer's solution, or physiological salt buffer. For transmucosal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are generally known in the art.
For oral administration, the pharmaceutical composition can be formulated readily by combining the active compounds with pharmaceutically acceptable carriers well known in the art. Such carriers enable the pharmaceutical composition to be formulated as tablets, pills, dragees, capsules, liquids, gels, syrups, slurries, suspensions, and the like, for oral ingestion by a patient. Pharmacological preparations for oral use can be made using a solid excipient, optionally grinding the resulting mixture, and processing the mixture of granules, after adding suitable auxiliaries if desired, to obtain tablets or dragee cores. Suitable excipients are, in particular, fillers such as sugars, including lactose, sucrose, mannitol, or sorbitol; cellulose preparations such as, for example, maize starch, wheat starch, rice starch, potato starch, gelatin, gum tragacanth, methyl cellulose, hydroxypropylmethyl-cellulose, sodium carbomethylcellulose; and/or physiologically acceptable polymers such as polyvinylpyrrolidone (PVP). If desired, disintegrating agents may be added, such as cross-linked polyvinyl pyrrolidone, agar, or alginic acid or a salt thereof such as sodium alginate.
Dragee cores are provided with suitable coatings. For this purpose, concentrated sugar solutions may be used which may optionally contain gum arabic, talc, polyvinyl pyrrolidone, carbopol gel, polyethylene glycol, titanium dioxide, lacquer solutions and suitable organic solvents or solvent mixtures. Dyestuffs or pigments may be added to the tablets or dragee coatings for identification or to characterize different combinations of active compound doses.
Pharmaceutical compositions which can be used orally, include push-fit capsules made of gelatin as well as soft, sealed capsules made of gelatin and a plasticizer, such as glycerol or sorbitol. The push-fit capsules may contain the active ingredients in admixture with filler such as lactose, binders such as starches, lubricants such as talc or magnesium stearate and, optionally, stabilizers. In soft capsules, the active ingredients may be dissolved or suspended in suitable liquids, such as fatty oils, liquid paraffin, or liquid polyethylene glycols. In addition, stabilizers may be added. All formulations for oral administration should be in dosages suitable for the chosen route of administration.
For buccal administration, the compositions may take the form of tablets or lozenges formulated in conventional manner.
In specific embodiments, the components and/or compositions of the invention are provided in form suitable for administration by inhalation or nasal administration.
For administration by nasal inhalation, the active ingredients for use according to some embodiments of the invention are conveniently delivered in the form of an aerosol spray presentation from a pressurized pack or a nebulizer with the use of a suitable propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane, dichloro-tetrafluoroethane or carbon dioxide. In the case of a pressurized aerosol, the dosage unit may be determined by providing a valve to deliver a metered amount. Capsules and cartridges of, e.g., gelatin for use in a dispenser may be formulated containing a powder mix of the compound and a suitable powder base such as lactose or starch.
The pharmaceutical composition described herein may be formulated for parenteral administration, e.g., by bolus injection or continuous infusion. Formulations for injection may be presented in unit dosage form, e.g., in ampoules or in multidose containers with optionally, an added preservative. The compositions may be suspensions, solutions or emulsions in oily or aqueous vehicles, and may contain formulatory agents such as suspending, stabilizing and/or dispersing agents.
Pharmaceutical compositions for parenteral administration include aqueous solutions of the active preparation in water-soluble form. Additionally, suspensions of the active ingredients may be prepared as appropriate oily or water based injection suspensions. Suitable lipophilic solvents or vehicles include fatty oils such as sesame oil, or synthetic fatty acids esters such as ethyl oleate, triglycerides or liposomes. Aqueous injection suspensions may contain substances, which increase the viscosity of the suspension, such as sodium carboxymethyl cellulose, sorbitol or dextran. Optionally, the suspension may also contain suitable stabilizers or agents which increase the solubility of the active ingredients to allow for the preparation of highly concentrated solutions.
Alternatively, the active ingredient may be in powder form for constitution with a suitable vehicle, e.g., sterile, pyrogen-free water based solution, before use.
The pharmaceutical composition of some embodiments of the invention may also be formulated in rectal compositions such as suppositories or retention enemas, using, e.g., conventional suppository bases such as cocoa butter or other glycerides.
Pharmaceutical compositions suitable for use in context of some embodiments of the invention include compositions wherein the active ingredients are contained in an amount effective to achieve the intended purpose. More specifically, a therapeutically effective amount means an amount of active ingredients (composition of matter comprising the components accountable for the biological effect) effective to prevent, alleviate or ameliorate symptoms of a disorder (e.g., NMRD) or prolong the survival of the subject being treated.
Determination of a therapeutically effective amount is well within the capability of those skilled in the art, especially in light of the detailed disclosure provided herein.
For example, any in vivo or in vitro method of evaluating the severity of NMRD symptoms may be employed.
For any preparation used in the methods of the invention, the therapeutically effective amount or dose can be estimated initially from in vitro and cell culture assays. For example, a dose can be formulated in animal models to achieve a desired concentration or titer. Such information can be used to more accurately determine useful doses in humans.
Toxicity and therapeutic efficacy of the active ingredients described herein can be determined by standard pharmaceutical procedures in vitro, in cell cultures or experimental animals. The data obtained from these in vitro and cell culture assays and animal studies can be used in formulating a range of dosage for use in human. The dosage may vary depending upon the dosage form employed and the route of administration utilized. The exact formulation, route of administration and dosage can be chosen by the individual physician in view of the patient's condition. (See e.g., Fingl, et al., 1975, in “The Pharmacological Basis of Therapeutics”, Ch. 1 p. 1).
Dosage amount and interval may be adjusted individually to provide the active ingredient at a sufficient amount to induce or suppress the biological effect (minimal effective concentration, MEC). The MEC will vary for each preparation, but can be estimated from in vitro data. Dosages necessary to achieve the MEC will depend on individual characteristics and route of administration. Detection assays can be used to determine plasma concentrations.
Depending on the severity and responsiveness of the condition to be treated, dosing can be of a single or a plurality of administrations, with course of treatment lasting from several days to several weeks or until cure is effected or diminution of the disease state is achieved.
The amount of a composition to be administered will, of course, be dependent on the subject being treated, the severity of the affliction, the manner of administration, the judgment of the prescribing physician, etc.
Compositions of some embodiments of the invention may, if desired, be presented in a pack or dispenser device, such as an FDA approved kit, which may contain one or more unit dosage forms containing the active ingredient. The pack may, for example, comprise metal or plastic foil, such as a blister pack. The pack or dispenser device may be accompanied by instructions for administration. The pack or dispenser may also be accommodated by a notice associated with the container in a form prescribed by a governmental agency regulating the manufacture, use or sale of pharmaceuticals, which notice is reflective of approval by the agency of the form of the compositions or human or veterinary administration. Such notice, for example, may be of labeling approved by the U.S. Food and Drug Administration for prescription drugs or of an approved product insert. Compositions comprising a preparation of the invention formulated in a compatible pharmaceutical carrier may also be prepared, placed in an appropriate container, and labeled for treatment of an indicated condition, as is further detailed above.
In another embodiment, the invention provides a nutritional or dietary compositions in the form of foods or beverages, which comprise the component(s) described herein. These foods or beverages comprise various exemplary embodiments of the inventive compositions. These foods or beverages can be prepared or provided as cereals, baby foods, healthy foods, or food for specified health uses such as solid food like chocolate or nutritional bars, semisolid food like cream or jam, or gel; and also as beverages. Specific and non-limiting examples of such food or beverage items include refreshing beverages, lactic acid bacteria beverages, drops, candies, chewing gum, chocolate, gummy candy, yoghurts, ice creams, puddings, soft adzuki bean jellies, jellies, cookies and the like.
The present teachings further envisage treating with other anti-viral drugs or anti-inflammatory drugs or anti-coagulants as separate treatments or in a co-formulation.
Without being limited to NMRD but for the sake of example, according to a specific embodiment, the antiviral drug is selected from the group consisting of remdesivir, an interferon, ribavirin, adefovir, tenofovir, acyclovir, brivudin, cidofovir, fomivirsen, foscarnet, ganciclovir, penciclovir, amantadine, rimantadine and zanamivir.

Many cell-based, in-vitro systems for evaluation of conditions comprising NMRD are available, in addition to traditional in-vivo animal models. To model NMRD, primary as well as cell lines of airway-associated cells such as pleural mesothelial cells (PMC), small airway epithelial cells (SAEC), bronchial epithelial cells (BEC), nasal epithelial cells, and bronchial fibroblasts are cultured and exposed to chemical/pathogenic insults. Cell responses, and in particular inflammatory processes, senescence and cell activation are determined in the presence or absence of added compositions and/or components of the invention, in order to evaluate the ability of the compositions and/or components of the invention to reduce or otherwise modify the effect of the insults on the cells. Cells can be propagated in 2-D or 3-D cultures.
For example, cells for in-vitro modeling of asthma include human pulmonary smooth muscle cells and airway epithelial cells. Cells for modeling of pulmonary fibrosis include pleural mesothelial cells. COPD can be modeled in vitro with bronchial fibroblasts, and asbestos/silica-induced damage can be evaluated using pleural mesothelial cells.
In an exemplary cell-based assay of fibrotic respiratory disease (e.g. COPD, asthma, IPF), fibroblast-to-myofibroblast transformation and epithelial-to-mesenchymal transition are assayed in normal lung fibroblasts and small airway epithelial cells.
Primary human lung fibroblasts or SAEC cells are induced into transformation with the pro-fibrotic growth factor TGFbeta-1, and markers of the different phenotypes (aSMA, collagen-I, fibronectin, E-cadherin) are evaluated. Anti-fibrotic effects of the compositions and/or components of the invention on the extent and character of transformation are evaluated.
Animal Models of Non-Malignant Respiratory Disease
Animal models for NMRD include induced animal models and naturally occurring animal models of the respiratory diseases and conditions.
Induced animal models suitable for assessing efficacy of the compositions and components of the invention include, but are not limited to:
A few naturally occurring animal models for NMRD are known and may be suitable for assessment of the effects of the compositions and/or components of the invention: IPF susceptibility is documented in certain breeds cats, dogs, horses and donkeys, and the asthma-like Hyperreactive Airway Disease is well known in horses and cats.
Although the invention has been described in conjunction with specific embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, it is intended to embrace all such alternatives, modifications and variations that fall within the spirit and broad scope of the appended claims.
COVID-19 is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The cell membrane ACE-2 receptor is an attachment and entry site for SARS-CoV-2. The ACE-2 receptor is a type I transmembrane metallocarboxypeptidase with homology to ACE, an enzyme long-known to be a key player in the Renin-Angiotensin system (RAS) and a target for the treatment of hypertension. There is evidence that SARS-CoV-2 utilizes ACE-2 as a cellular entry receptor. Zhou et al. showed that SARS-CoV-2 could use ACE-2 from humans, Chinese horseshoe bats, civet cats, and pigs to gain entry into ACE-2-expressing HeLa cells (See Zhou, P., Yang, X L., Wang, X G. et al. A pneumonia outbreak associated with a new coronavirus of probable bat origin. Nature 579, 270-273 (2020)). The spike (S) protein of SARS-CoV-2, which plays a key role in the receptor recognition and cell membrane fusion process, is composed of two subunits, S1 (120 kDa) and S2 (80 kDa). The S1 subunit contains a receptor-binding domain that recognizes and binds to the host receptor angiotensin-converting enzyme 2 (ACE-2). The S2 subunit mediates viral cell membrane fusion by forming a six-helical bundle via the two-heptad repeat domain (see Huang, Y., Yang, C., Xu, Xf. et al. Structural and functional properties of SARS-CoV-2 spike protein: potential antivirus drug development for COVID-19. Acta Pharmacol Sin 41, 1141-1149 (2020)). Interfering, attenuating, impairing the function of the S1 and S2 subunits will eventually lead to an attenuated, impaired and less infective virus.
The materials used in all the following viral protein digestion assays are disclosed in table 1.
Each of the tested plant based treatment was numbered as disclosed in table 2 and the tested combinations complexes were classified as disclosed in table 3
Oils mixtures were prepared by mixing equal amounts of each oil. The mix was then diluted 1:2 with DMSO, to acquire a solution of 50% DMSO, 50% Oil mix and the final reaction concentration was 5% oil mix, 5% DMSO.
For each assay reaction, 1 μg protein per reaction was incubated with 3 μl of the oil mixture at final reaction volume of 30 μl. The reaction was incubated for 6 hours at 37° C.
Following incubation, the reaction was stopped by adding 10 μl/reaction of sample buffer 4× and incubation 10 minutes at 72° C. Samples were then run in 4-15% TGX Criterion Gel (BIORAD) for 50 minutes at 200 Volt. Following run, the gel was incubated for 1 hour with Instant Blue reagent (Expedeon) and further washed with water until distinct bands were observed.
Densitometry was preformed, pictures were analyzed with ImageJ software.
The protein digestion assay was conducted as disclosed in table 4. SARS-CoV-2 S1 subunit, SARS-CoV-2 S2 subunit, SARS-CoV-2 Nucleocapsid protein and a negative control with no protein, were incubated with different plant oils or combinations for 6 h at 37° c. and subsequently run on SDS-page, stained with “instant blue” for the presence of proteins in the gel. The untreated control appeared at the expected molecular weight and the effect of different treatments were compared to this control (see
Densitometry of the SARS-CoV-2 S1 subunit, SARS-CoV-2 S2 subunit, SARS-CoV-2 and the Nucleocapsid protein assays disclose that although the Nucleocapsid protein underwent little to no digestion with either of the tested treatments as compared to the protein K treatment the two SARS-CoV-2 subunits S1 and S2 underwent a substantial digestion (see
To conclude, the viral protein digestion assay demonstrates that there is a significant digestion of the S1 and S2 subunits without destroying the Nucleocapsid protein.
Following incubation of the protein with a mix prepared from equal volumes from items 1+2+3+4 (complex B), a 26% reduction in the protein signal was observed.
Following incubation of the protein with a mix prepared from equal volumes from items 1+2+3+4 (complex B), a 19% reduction in the protein signal was observed.
Following incubation of the protein with a mix prepared from equal volumes from items 1+2+3+4+5 (complex C), a 27% reduction in the protein signal was observed
Following incubation of the protein with a mix prepared from equal volumes from items 1+2+3+4+5+6 (complex D), a 47% reduction in the protein signal was observed.
These significant digestion rates of both S1 and S2 subunits of the spike protein are likely to result in the subsequent attenuation of the Coronavirus cell attachment and internalization mechanism. It is clear that attenuating the virus cell attachment and internalization mechanism, disease levels and viral load can be reduced in an infected subject, or prevent an uninfected subject from getting infected.
