The present disclosure relates to the compound 4-(4,5-bis(4-bromophenyl)-2-phenyl-1H-imidazol-1-yl)benzoic acid, its synthesis, and its use as an antimicrobial agent.
Bacterial infection remains a significant threat to human life due to its increasing resistance to conventional antibiotics, which is a growing public health concern. As a result, there is a critical need to create new antimicrobial agents with potent anti-drug-resistant microorganism activity. That is why antimicrobial agent investigations are so critical and should always be up to date.
The chemistry of heterocycles lies at the heart of drug discovery. Investigation of such organic compounds for drug discovery has been a rapidly emerging theme in medicinal chemistry. For example, imidazole derivatives are well-known heterocyclic compounds known to be useful in a variety of medicinal agents. Based on various literature surveys, certain imidazole derivatives have shown various pharmacological activities, such as anti-bacterial, anti-fungal, anti-inflammatory, analgesic, anti-depressant, anti-viral, anti-cancer, antileishmanial, and anti-tubercular activities.
In recent years, there has been a tremendous upsurge of interest in various chemical transformations performed under ultrasound irradiation. With the use of ultrasound irradiation, chemical transformations can occur, with higher yields and purity of the products, shorter reaction times, and milder conditions, that create economic advantages. This greener method, i.e., the ultrasound technique, is crucial to reduce the negative impact of traditional methods. Hence, the ultrasound technique is a green chemistry technique that is quicker and healthier than conventional synthetic methods.
Green chemistry is a new approach to the development of sustainable chemical processes aimed at the minimization or elimination of the utilization and generation of hazardous substances. In the 21st century, incorporation of the principles of green chemistry in organic synthesis has gained increasing interest, since the reduction of toxic, flammable volatile organic solvents (VOCs), and strong catalysts is of high importance. However, to achieve more environmentally friendly protocols for the synthesis of organic compounds, the redesign of reactions and modifications of existing chemical processes is often required.
Among solvents, ionic liquids (ILs) have been rather sanguinely viewed as environmentally friendly or “green” solvents. Ionic liquids are non-flammable, chemically, electrochemically and thermally stable, with negligible volatility. Indeed, they are named green solvents, as their low volatility allows them to limit VOC emissions compared to conventional solvents.
Multi-component reactions (MCRs) are economically and environmentally beneficial to industry and have attracted much attention.
Thus, new molecules and synthetic methods for obtaining the same having desired therapeutic activities and solving the aforementioned problems are desired.
The present subject matter relates to a new imidazole derivative in order to provide a limited library of “drug-like” substances. In this regard, the present subject matter relates to a compound, 4-(4,5-bis(4-bromophenyl)-2-phenyl-1H-imidazol-1-yl)benzoic acid (V), synthesized via a one-pot, four-component reaction of 1,2-bis(4-bromophenyl)ethane-1,2-dione (I), benzaldehyde (II), 4-aminobenzoic acid (III), and ammonium acetate (IV) in Pyridinium Ionic Liquid as a catalyst and green solvent. In addition, the present synthetic method can use and ultrasonic technique as a source of heat, making it an eco-friendly method. The product can be acquired in exceptional yields (average about 73%). The important characteristics of using this method are excellent yielding products, limitation of the reaction times, and ease of use. Additionally, the reaction components could be purified by some non-chromatographic technique and the ionic liquid catalysts can be recycled again and used with this efficiency. The product can been analyzed using spectral data; IR, NMR & elemental analysis. The prepared compound can be used for antimicrobial activity, which gave high efficiency against different microbes.

The present compounds may also be administered as compositions prepared as foods for humans or animals, including medical foods, functional food, special nutrition foods and dietary supplements. A “medical food” is a product prescribed by a physician that is intended for the specific dietary management of a disorder or health condition for which distinctive nutritional requirements exist and may include formulations fed through a feeding tube (referred to as enteral administration or gavage administration).
A “dietary supplement” shall mean a product that is intended to supplement the human diet and may be provided in the form of a pill, capsule, tablet, or like formulation. By way of non-limiting example, a dietary supplement may include one or more of the following dietary ingredients: vitamins, minerals, herbs, botanicals, amino acids, and dietary substances intended to supplement the diet by increasing total dietary intake, or a concentrate, metabolite, constituent, extract, or combinations of these ingredients, not intended as a conventional food or as the sole item of a meal or diet. Dietary supplements may also be incorporated into foodstuffs, such as functional foods designed to promote control of glucose levels. A “functional food” is an ordinary food that has one or more components or ingredients incorporated into it to give a specific medical or physiological benefit, other than a purely nutritional effect. “Special nutrition food” means ingredients designed for a particular diet related to conditions or to support treatment of nutritional deficiencies.
Generally, depending on the intended mode of administration, the pharmaceutically acceptable composition will contain about 0.1% to 90%, for example about 0.5% to 50%, by weight of the present compound, the remainder being suitable pharmaceutical excipients, carriers, etc.
One manner of administration for the conditions detailed above is oral, using a convenient daily dosage regimen which can be adjusted according to the degree of affliction. For such oral administration, a pharmaceutically acceptable, non-toxic composition is formed by the incorporation of any of the normally employed excipients, such as, for example, mannitol, lactose, starch, magnesium stearate, sodium saccharine, talcum, cellulose, sodium croscarmellose, glucose, gelatin, sucrose, magnesium carbonate, and the like. Such compositions take the form of solutions, suspensions, tablets, dispersible tablets, pills, capsules, powders, sustained release formulations and the like.
The present compositions may take the form of a pill or tablet and thus the composition may contain, along with the active ingredient, a diluent such as lactose, sucrose, dicalcium phosphate, or the like; a lubricant such as magnesium stearate or the like; and a binder such as starch, gum acacia, polyvinyl pyrrolidine, gelatin, cellulose and derivatives thereof, and the like.
Liquid pharmaceutically administrable compositions can, for example, be prepared by dissolving, dispersing, etc. an active compound as defined above and optional pharmaceutical adjuvants in a carrier, such as, for example, water, saline, aqueous dextrose, glycerol, glycols, ethanol, and the like, to thereby form a solution or suspension. If desired, the pharmaceutical composition to be administered may also contain minor amounts of nontoxic auxiliary substances such as wetting agents, emulsifying agents, or solubilizing agents, pH buffering agents and the like, for example, sodium acetate, sodium citrate, cyclodextrin derivatives, sorbitan monolaurate, triethanolamine acetate, triethanolamine oleate, etc.
For oral administration, a pharmaceutically acceptable non-toxic composition may be formed by the incorporation of any normally employed excipients, such as, for example, pharmaceutical grades of mannitol, lactose, starch, magnesium stearate, talcum, cellulose derivatives, sodium croscarmellose, glucose, sucrose, magnesium carbonate, sodium saccharin, talcum and the like. Such compositions take the form of solutions, suspensions, tablets, capsules, powders, sustained release formulations and the like.
For a solid dosage form, a solution or suspension in, for example, propylene carbonate, vegetable oils or triglycerides, may be encapsulated in a gelatin capsule. Such diester solutions, and the preparation and encapsulation thereof, are disclosed in U.S. Pat. Nos. 4,328,245; 4,409,239; and 4,410,545, the contents of each of which are incorporated herein by reference. For a liquid dosage form, the solution, e.g., in a polyethylene glycol, may be diluted with a sufficient quantity of a pharmaceutically acceptable liquid carrier, e.g., water, to be easily measured for administration.
Alternatively, liquid or semi-solid oral formulations may be prepared by dissolving or dispersing the active compound or salt in vegetable oils, glycols, triglycerides, propylene glycol esters (e.g., propylene carbonate) and the like, and encapsulating these solutions or suspensions in hard or soft gelatin capsule shells.
Other useful formulations include those set forth in U.S. Pat. Nos. Re. 28,819 and 4,358,603, the contents of each of which are hereby incorporated by reference.
Another manner of administration is parenteral administration, generally characterized by injection, either subcutaneously, intramuscularly or intravenously. Injectables can be prepared in conventional forms, either as liquid solutions or suspensions, solid forms suitable for solution or suspension in liquid prior to injection, or as emulsions. Suitable excipients are, for example, water, saline, dextrose, glycerol, ethanol or the like. In addition, if desired, the pharmaceutical compositions to be administered may also contain minor amounts of non-toxic auxiliary substances such as wetting or emulsifying agents, pH buffering agents, solubility enhancers, and the like, such as for example, sodium acetate, sorbitan monolaurate, triethanolamine oleate, cyclodextrins, etc.
Another approach for parenteral administration employs the implantation of a slow-release or sustained-release system, such that a constant level of dosage is maintained. The percentage of active compound contained in such parenteral compositions is highly dependent on the specific nature thereof, as well as the activity of the compound and the needs of the subject. However, percentages of active ingredient of 0.01% to 10% in solution are employable and will be higher if the composition is a solid which will be subsequently diluted to the above percentages. The composition may comprise 0.2% to 2% of the active agent in solution.
Nasal solutions of the active compound alone or in combination with other pharmaceutically acceptable excipients can also be administered.
Formulations of the active compound or a salt may also be administered to the respiratory tract as an aerosol or solution for a nebulizer, or as a microfine powder for insufflation, alone or in combination with an inert carrier such as lactose. In such a case, the particles of the formulation have diameters of less than 50 microns, for example less than 10 microns.
In an additional embodiment, the present subject matter relates to a method of treating a microbial infection in a patient comprising administering to a patient in need thereof a therapeutically effective amount of the 4-(4,5-bis(4-bromophenyl)-2-phenyl-1H-imidazol-1-yl)benzoic acid compound.
