Carbonic Anhydrase Enzymes are ancient Zinc enzymes which are further divided into alpha, beta and gamma carbonic anhydrase enzymes as illustrated in
Carbonic anhydrase enzymes are the fastest enzymes doing 10(6) power reactions per second. In mammals, their activities are not limited to maintaining the acid base balance, maintaining the PO2/CO2 ratio, ester hydrolysis, ion transport, phospatase activity, CO2 hydration, maintaining the equilibrium between H2O, CO2 and H+HC03− in all spaces, cellular, interstitial and vascular spaces as illustrated in
In Mammals Carbonic Anhydrase Isozymes (Genes) are further divided into: Cell Specific Carbonic Anhydrase I to XIV:
CA-I are cytosolic enzymes are mostly found in Red blood Cells, vascular endothelial cells, gastrointestinal mucosa
CA-II are cystosolic enzyme found in almost all tissues but mainly in the Brain, Bones, Kidneys
CA-III—cystosolic enzyme mostly found in muscles, synovial tissues
CA-IV is membrane bound, found in the capillary endothelial cells, brain and kidney

CA-VI secretory found in tears saliva, milk, mammary gland, nasal and respiratory mucosa
CA-VII cystosolic Enzyme-hippocampal CA I pyramidal cells, salivary Glands
CA VIII—CARP(carbonic anhydrase related protein)
CA-IX—Membrane Bound MN/protein(tumor associated)—Catalytic

CA-XI—CARP(carbonic anhydrase related proteins)
CA-XII—Membrane Bound
CA-XIII—cystosolic

In describing their work in an article entitled “Studies on age-Dependent Ozonide Changes in Human Cerebral Cortex,” (by Reichlmeier K., Ermini M., and Schlecth H. P.—Aktuellel Gerontl 1978 Aug. 8(8):44-8) the authors report that they investigated the activity of various enzymes of human brains obtained at autopsy and covering an age range of 19 to 91 years. Protein Kinase, which mediates the information carried by the second messenger, cyclic AMP(3′,5′-cyclic adenosine monophosphate), does not show age-related changes of basal activity. Cyclic AMP-dependent activation of protein kinase remains constant up to 60 years of life but it undergoes a distinct and progressive decline between 60 and 90 years. In the corpus striatum, no age related changes of cyclic AMP-dependent protein activity were observed. The activity of carbonic anhydrase exhibits, in both human cortex and corpus striatum, an age-dependent decrease that also begins after the sixth decade.
Aging is further divided into primary aging and secondary aging (accelerated). Primary aging is caused mainly in the inherent progressive decrease activities of the genes that regulates the cell. While secondary aging (accelerated) is caused mainly by oxidative stress. Oxidative stress is caused mainly by external factors such as environmental factors, toxic materials, ionizing radiations, or any disease or condition that alters the vascular endothelium and the cell wall membrane. These altered conditions allows the entry of substances that will displace the zinc from cell specific carbonic anhydrase enzymes leading to the decreased level of cell specific carbonic anhydrase enzymes hence leading to cellular death.
In Aging there is an age-associated dysregulated inflammatory and Immune Response. There is an increase production of PGE2 and Cyclooxygenase which inhibits the production of Cell Specific Carbonic Anhydrase Enzymes
IN Brain Behav Immun. 2004 November; 18(6):487-94 by Wu D, Meydani S N Mechanism of age-associated up-regulation in macrophage PGE2 synthesis Many physiological functions of the body change during the aging process. Disregulated immune and inflammatory responses have been well documented in both humans and animals. The investigation into the cellular and molecular mechanism underlying these disorders has provided compelling evidence that up-regulated cyclo-oxygenase (COX2) and its product particularly prostaglandin (PGE2) lay a critical role in the age-associated disregulation of the immune and inflammatory responses. Studies have shown that increase production of PGE2 by old macrophages contributes to the suppresion of T cell function. Decreasing production of PGE2 have shown enhanced T mediated cell function. Upon Stimulation, old mice macrophages generate more ceramide which in turn augments stimulated COX2 expressions and PGE2 production.

Prostaglndins (PGS) are potent eicosanoid lipid mediators derived from phospholipase released arachidonic acid, which are involved in numerous homeostatic biological functions and inflammation. Along with their role in inflammatory responses evidence strongly suggest that PGS, including PGD2 are part of the complex regulatory network that modulates the immune system. PGE2 is the major prostaglndin activated by mast cells in allergic diseases.

ANTIBODIES to Cell Specific Carbonic Anhydrase Enzymes are produced as a result of an immunologic response to exposure to antigens in Humans. These antigens try to destroy these enzymes and so the human body try to defend itself by producing cell specific carbonic anhydrase antibodies.

Cancer is the uncontrollable growth of cells originating from normal tissues and the property of killing the host by means of local extension or distant spread. They are unresponsive to normal regulatory factors, they lose their property to differentiate and lose the function of normal tissue of origin.
Cancer is further divided into undifferentiated forms and well differentiated forms. Undifferentiated forms are immature and do not look like the tissue it arose and very aggressive while the opposite is true for the differentiated form.
Cell specific carbonic anhydrase enzymes are growth factors of stem cells. Abnormal expressions of Cell specific carbonic anhydrase enzymes maybe due to Primary Gene mutation (Hereditary) and Secondary Gene mutation (due to oxidative stress). These mutant Genes causes abnormal growth of cells in the form of new-growths such as cancer. These mutant genes could produce either an increased or decreased levels of cell specific carbonic anhydrase enzymes. The decreased levels of Cell Specific Carbonic Anhydrase Enzymes, results to: the cells are unable to differentiate to mature cells such as found in undifferentiated forms of cancers. Excessive production of cell specific carbonic anhydrase enzymes causes excessive production of cellular elements such as found in well differentiated forms of cancer.

THE present invention provides the therapeutic and prophylactic uses of cell specific carbonic anhydrase I to VII, its activators and inhibitors for the treatment of aging and disorders of aging which includes oxidative stress; cancer;as growth factors of stem cells and as alternative to stem cell therapy. These conditions or diseases are associated with either an increased or decreased levels of cell specific carbonic anhydrase enzymes such as found in certain forms of cancers: breast, colon, prostate, esophagus, liver, pancreas, rectum, testis, ovary.
In aging, the decreased levels of cell specific carbonic anhydrase enzymes leads to the decreased levels of Hydrogen ions used as fuel of the ion pump that maintains the integrity of the cell wall membrane, decreased levels of hydrogen ions needed to neutralize all reactive substances leading to oxidative damages to almost all molecules of the subject; and also decreased fuel for other cellular functions. These diseases or conditions include but not limited to immune diseases which includes systemic lupus erythematosus, diabetes mellitus, chronic neurodegenerative disorders which includes but not limited to alzheimer's disease, multiple sclerosis, Lou gehrig's disease, parkinson's disease, autism; bone disorders which includes but not limited to osteoporosis, osteomalacia, osteopetrosis, rickets, arthritis, osteoarthritis, rheumatoid arthritis; amyloidosis; arterioslclerosis; atherosclerosis, cardiomyopathies, endothelial dysfunctions; cystic fibrosis; integumentary dysfunctions which includes wrinkling of the skin; myositic dysfunction; lipid dysfunctions; ischemic heart disease; and other diseases associated with human aging including oxidative stress.

The following represents an essential chemical reaction that takes place in a mammalian tissue. GLucose (Within the Cells)+Oxygen—H2O+CO2—H++HCO3− Carbonic Anhydrase present (reversible reaction) Eq. (1)
Glucose is irreversibly oxidized within the cells to produce water and carbon dioxide. In the presence of a catalyst, especially a carbonic anhydrase enzyme (of which several forms exist, of which the form present depends upon the type of tissue cell present), the water and carbon dioxide reversibly produce a hydrogen ion and a bicarbonate ion.
Carbonic Anhydrase is a Zinc-containing enzyme that catalyses the reversible CO.sub.2 hydration reaction illustrated in Eq.1. The mitochondria of cells of different tissues and organs produce different specific carbonic anhydrase enzymes that maintain the equilibrium of the above equation in all spaces-cellular, interstitial, and vascular—as illustrated in
Hydrogen ion produced by carbonic anhydrase enzymes is acted upon by the cytochrome system, which is then utilized as the energy source of the ion pump that maintains the integrity of the cell membrane comprising and enclosing each cell. It is also thought to be the source of the brain's electric current. The proces is schematically illustrated in
Disruption of the process that include Eq. 1 causes depolarization of the cell wall membrane, hence (Na), water (H.sub.2O), and other chemicals can enter the cell in uncontrollable amounts and potassium (K) can exit uncontrollably, leading to the death and destruction of the involved cells; cellular edema follows. As the edema progresses, the cell dies. Along with the progressive and gradual death of cells, gliosis follows—hence aging in the brain occurs (
In this newly presented instant invention as illustrated in Fig. I Hydrogen ions produced by cell specific carbonic anhydrase enzymes are acted upon by the cytochrome system and they are utilized as fuel H++ADP—(adenosine diphospate)—ATP(adenosine triphosphate) for other cellular functions (cell metabolism).
Cell Metabolism—ATP(Adenosine Triphospate)—H+(hydrogen)+ADP (Adenosine diphospahte)+energy (½ for cell division and ½ for general cell metabolism)
In this newly presented instant invention as illustrated in
In the Mitochondria 1% to 5% of Oxygen free radicals are formed.
Glucose+O2—H2O+CO2+(O2)−2(reactive Oxygen)
Oxygen−2 electrons—(O2)−2
In the Cytochrome System, Hydrogen ions produced by Carbonic Anhydrase Isozymes also acts as powerful anti oxidant, combining with reactive oxygen as illustrated in the following steps:
Hydrogen ions produced:(from Carbonic Anhydrase isozymes)
2. H++(O2)−2—(HO2)−1(superoxide)
3. H++(HO2)−1—H2O2(Hydrogen peroxide)
4. H2O2—2(OH−1)(Hydroxyl)
5. 2H++2(OH−1)—2(H2O)(water)-final product
Hydrogen ions produced by carbonic anhydrase enzymes neutralizes all reactive subastances.
Lack of Hydrogen ions due to deficiency of Cell specific carbonic anhydrase enzymes do not complete the above reactions, the final product being water (H2O).This leads to the increase levels of reactive oxygen.
These reactive oxygen causes lipid oxidation, protein oxidation, DNA fragmentations, disruption of the cell wall membrane & binds with almost all molecules in the body. These reactive oxygen species are implicated with diseases associated with oxidative stress which includes but not limited to cancer, aging, immune diseases, atherosclerosis neurodegenerative conditions or diseases.
Hydrogen ions produced by cell specific carbonic anhydrase enzymes are acted upon by the cytochrome system are used by proteins to make them more stable. It has been shown that removing the hydrogen bond leads to protein misfolding leading to diseases and abnormal conditions in a subject which includes amyloidisis.
J Theor Biol. 2002 Apr. 21; 215(4):399-404 Hydrogen Bonds and the Catalytic mechanism of human carbonic anhydrase II-by Thomas S
Tells us the production of hydrogen bonds by carbonic anhydrase II making a substance more stable. Oxidative stress is associated with an increase of amyloid precursor proteins leading to amyloid depositions all over the body of a subject.
Carbonic anhydrase enzyme has been used to augment the extracellular ph buffering in the cerebral cortex of rats (Journal of Neurophysiology 1995 October 74(4):1806-9. It is known that the blood brain barrier in animals is incomplete compared to that of humans where the blood brain barier is complete and a formidable barrier to chemical transport. Substances that prove efficacious in affecting the brain chemistry of animals are not necessarily efficacious in the brains of human beings because they cannot pass through the more complete blood brain barier in humans. Although some researchers equivocate on this concept most of the medical community accepts the idea that carbonic anhydrase enzymes traverse the blood brain barrier in humans as fact, especially regarding the carbonic anhydrase enzyme referred to as CA-II.
As far as can be determined in the literature, cell specific carbonic anhydrase enzymes have never been used to restore to a higher level the carbonic anhydrase enzymes that are lacking due to decreased levels due to normal aging. At least some of the carbonic anhydrases have been extracted from animal tissue, isolated, and studied for molecular structure. This shows that the enzymes can be isolated and made available for administration to a patient for therapeutic or prophylactic treatment.
In U.S. Pat. No. 5,972,684, Bandman et al. tell us:
Eight enzymatic and evolutionary related forms of carbonic anydrase enzymes are currently known to exist in humans; three cystosolics (CA I, CA II, CA III), two membrane bound forms (CA IV, and CA VII), a mitochondrial form (CA V), a secreted salivary form (CA VI) and a yet uncharacterized Isoforms show a characteristic motif.(See, e.g., http://expassy.hcuge.ch).Though the isoenzymes CA I, CA II, and bovine CA III have a similar secondary structure and polypeptide chain fold, CA I has 6 tryptophans, CA II has 7 and CA III has 8(Boren, K et al. (1996) Protein Sc. 5(12):2479-2484). CA II is the prodominant CA isoenzyme in the brain of mammals.
Inhibition and activation of CA provide information about CA structure and activity. vasodilating prostaglandins E1, E2, E12 inhibit CA in vitro and in vivo and may inhibit the involvement of CA in gastric acid secretion. Nonsteroidal anti-inflammatory drugs which reduce the activity of cyclooxygenase and prostaglandin production have also been observed to activate CA I, and CA II in dose dependent non competetive manner. The pre-prostaglandin cyclooxygenase appears to maintain an inverse relantionship with CA, probably mediated by the ph variations associated with carbonic anhydrase activity
(Puscas, I (1996) J. Pharmacol. Exp. Ther. 277(3):1464-1466). Both prostaglandins E2 and E12 inhibit gastric acid output. Prostaglandin E2 inhibits egress of norepinephrine from sympathetic nerve terminals.
The Bandman et al. teaches another carbonic anhydrase enzyme, CA-VIII, the subject of their patent. The present patent does not deal with nor address CA-VIII
Patients having a carbonic anhydrase VI(CA-VI) deficiency have been treated with orally administered Zinc in an effort to stimulate the synthesis/secretion of CA-VI and the successful results were reported in the American Journal of Medical Science (Efficacy of Exogenous oral Zinc in the treatment of patients with carbonic anhydrase deficiency, by Benkin R. I., Martin, B. M., 1 and Agarwal, R. P.—Am J Med Sci 1999 Dec. 3; 18(6):392-405). The Carbonic Anhydrase VI produced acted as growth factors of stem cell taste buds in Patients. Thus it is shown that the synthesis/secretion of carbonic anhydrase can, indeed, be stimulated by compounds administered orally and also this has been shown that Carbonic anhydrase isozymes can be administered as growth factors of stem cells, and hence an alternative to stem cell therapy.

Whereas in aging, there has been observed a progressive decrease in levels of enzymes of which carbonic anhydrase is one, I believed that replenishing the carbonic anhydrase enzymes that catalyze the reversible reaction of Equation 1 will at least slow the progressive and gradual death of all cells, including cells in the brain, which brain cell reduction is a major contributor to various age-related brain disorders involving dementia such as alzheimer's disease, other neurodegenerative diseases or conditions and other aged related disorders or conditions in humans.
The progressive decrease of cell specific carbonic anhydrase enzymes also results in the progressive decrease of hydrogen ions acted upon by the cytochrome system which is needed to neutralize reactive substances including but not limited to reactive oxygen species (ROS) produced during cell respiration resulting in oxidative damages to all cellular and non-cellular structures, as illustrated in
Specific Carbonic Anhydrase Enzymes I,II,III,IV,V,VI,VII have never been used to restore to a higher level the Carbonic anhydrase enzymes that are lacking due to decreased levels due to normal aging, diseases associated with aging which includes cancer due to oxidative stress or whether the replenishing enzymes are naturally produced and harvested or synthetically produced, nor has anyone used for this purpose any carbonic anhydrase stimulators to stimulate a patient's production of carbonic anhydrase enzymes.
As far as can be determined from the literature, one or more Cell Specific Carbonic Anhydrase enzymes have never been used as a treatment or prophylaxis for the treatment of immune diseases, whether administering one or more compounds that increases the level of one or more Cell Specific Carbonic Anhydrase enzymes that are present in decreased levels due to immune disorders of Humans, which include but are not limited to alzheimer's disease, systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis, ulcerative colitis immune diabetes mellitus, pancreatitis, colitis, syogren's disease, hepatitis, nephritis, myositis.
Likewise, No one has ever used one or a combination of one or more cell specific carbonic anhydrase enzymes I to VII PER SE in treating aging and disorders of aging in a human subject.
Likewise no one has ever used one or more compounds which naturally generates the production of one or more cell specific carbonic anhydrase enzymes I to VII as growth factors for replacing damaged or diseased cells or tissues and as growth factors of human stem cells whether they are adult or embryonic stem cells.
Nor has anyone used Carbonic anhydrase enzymes I to VII as an alternative for stem cell in the treatment of diseases or conditions.
Likewise no one has ever used a compound that increases the level of Cell specific Carbonic anhydrase I,II,III,IV,V,VI,VII as an ANTIOXIDANT in treating diseases or conditions associated with oxidative stress.
Carbonic Anhydrase isozyme inhibitors I to VII has never been used in the treatment of Cancer in humans before acetazolamide was used in the 1990″s as adjuvant treatment for lung cancer for its acidifying effect.

They postulate that the mechanism may be involved in the ability of acetazolamide to acidify the intratumoral environment.
Here they do not emphasize the importance of taking the level of Carbonic anhydrase isozyme from the tissue (cancer) before giving the drug acetazolamide. Their teachings, suggestions and motivations are different from that of the inventor.
Eur J Med Chem. 2000 September; 35(9):876-74—by Supuran C T, Scozzafava Carbonic anhydrase inhibitors—Part 94. 1,3,4,-thiadiazole-2-Thiadazole-2-sulfonamide against CAII and CA VI as antitumor agents.
They teach that this compound is an inhibitor of Carbonic Anhydrase isozyme I and II against several leukemia, non-small cell lung cancer, ovarian, melanoma, colon, CNS, renal, prostate and breast cancer lines. The mechanism was unknown, but it might be due to inhibition of several Carbonic anhydrase isozymes (CA IX, CA XII, CA XIV) or acidification of the intracellular environment as a consequence of Carbonic anhydrase isozyme inhibition.
They do not know the mechanism by which the hydrogen ions produced by cell specific carbonic anhydrase acted upon by the cytochrome system inside the mitochomdria of all living things as in
I have come to realization that administering supplemental cell specific carbonic anhydrase enzymes or administering cell specific carbonic anhydrase stimulators or inhibitors, diseases associated with aging such as but not limited immune diseases, cancer can be prevented or treated. This can be achieved by maintaining near normal levels of cell specific carbonic anhydrase enzymes of a subject either by increasing or decreasing the levels of one or a combination of one or more cell specific carbonic anhydrase enzymes that are present in the tissue of the subject.
This method can be done by directly administering the cell specific carbonic anhydrase enzymes themselves, administering one or more compounds that stimulates the production of one or more cell specific carbonic anhydrase enzymes.
For the treatment of cancers associated with an increased expression of cell specific carbonic anhydrase enzymes in the tissues, Cell specific carbonic anhydrase inhibitors are administered in a non toxic and pharmaceutically effective dose to reduce the level of the Carbonic anhydrase isozymes back to normal levels. Maintainance dose is continued till the cancer cells goes back to normal cells.
Cell specific carbonic anhydrase enzymes I-VII can also be used as growth factors in treating diseases .This can be achieved by assaying which one or a combination of one or more cell specific carbonic anhydrase enzyme is or are present in the diseased or damaged cell or organ to be treated and then, Administering one or a combination of one or more compounds that increases the level of one or more cell specific carbonic anhydrase I-VII that are present in a specific cell or tissue to be replaced, either because of disease or from injury, then maintaining the normal levels of the same Cell Specific Carbonic anhydrase enzymes from I-VII that is present in the subject's cell or tissue to be replaced, diseased, or damaged.
This treatment can be administered to patients exhibiting diseases associated with aging such as but not limited to immune diseases, cancer and other related diseases of aging. It is also feasible to administer this treatment as a prophylactic or preventative diseases associated with aging to prevent or at least delay the onset of diseases associated with aging such as chronic neurodegenerative diseases, including but not limited to alzheimer's disease, multiple sclerosis, parkinson's disease, amyotrophic lateral sclerosis (Lou Gehrig's disease). This present treatment can be administered to prevent or at least delay age related disorders of aging which includes but not limited to the central nervous system, digestive system, excretory system, integumentary system, circulatory system, musculoskeletal system, reproductive system.
These compounds can be used as antioxidants in the prophylactic and therapeutic treatment of diseases associated with oxidative stress such as but not limited to aging, immune diseases, cancer.Oxidative stress is characterized by decreased level of hydrogen ions produced as a result of decreased levels of carbonic anhydrase isozymes, which maybe due to normal aging or conditons or diseases described in
Thus, I disclose here a method for the treatment and prophylaxis of diseases associated with aging associated with an increase or decrease presence of cell specific carbonic anhydrase I-VII in the tissue of a patient such conditions associated but not limited to Cancer, aged related disorders, as growth factors of stem cells, as an alternative to stem cell therapy.
The compound used could be the cell specific carbonic anhydrase that is believed to be evidencing decreased presence as measured in the blood tests or in cell cultures from biopsied tissues or from the cerebro-spinal fluid. Alternatively, the compound used could be synthetically produced cell specific carbonic anhydrase enzymes. As, alternative the compound used colud be naturally produced cell specific carbonic anhydrase enzymes. Yet another alternative allows that the compound used is a compound that, when administered to a patient, promotes the natural production of the cell specific carbonic anhydrase enzyme that is evidencing decreased presence as measured in blood test or in cell cultures in biopsied tissues or from the cerebro-spinal fluid. The compound itself need not be the one that passes the blood brain barrier;the cell specific carbonic carbonic anhydrase enzyme need not be produced in the brain for it is known to pass the blood brain barrier so the promoting of natural production of cell specific carbonic anhydrase enzyme can take place elsewhere in the body.
The compound used is one or more compounds that decreases the level of one or more Cell specific carbonic anhydrase enzymes in the tissue of a patient whose levels are increased, decreasing the Carbonic anhydrase isozymes back to normal levels.
Examples of compounds that are known to decrease the presence of the required Cell specific carbonic anhydrase enzymes include but are not limited to acetazolamide and its derivatives, sulfonamides incorporating 1,2,4-triazine moieties, sulfonamide and its derivatives. derivatives of benzene sulfonamides inhibit CA II, CA V; CA IV best inhibited with phosphates, phosphonates. CA I inhibited by carbamoyl phosphate, Na Azide and Potassium cyanide are universal Carbonic anhydrase inhibitors.
Examples of compounds that are known to increase the producton of the required cell specific carbonic anhydrase enzymes include but are not limited to Zinc, growth hormones, androgens including DHEA(dehydro-epiandrosterone), sex hormones which includes estrogen, testosterone acetylcholine, melatonin, 1,25-dihydroxyvitamin D3 including vitamin D3 (cholicalciferol), NSAID (non steroidal anti-inflammatory drugs) including indomethacin; cysteamine; phorbol myristate acetate, histamine, serotonin; selective serotonin re-uptake inhibitors including sertraline, citalopram, fluoxetine. Zinc increases the production of Carbonic anhydrase VI; growth hormones increases the production of Carbonic anhydrase II, III; NSAID (non steroidal anti-inflammatory drugs) increases the production of Cell specific Carbonic anhydrase I, II; sex hormones estrogen, testosterone increases the production of carbonic anhydrase III; 1,25 dihydroxyvitamin D3 increases the production of Carbonic anhydrase II; Histamine and cysteamine increases the producion of Carbonic anhydrase I, II, IV; the selective serotonin reuptake inhibitors which includes sertraline, fluoxetine, citalopram increases the production of carbonic anhydrase I, II; acetylcholine increases the production of carbonic anhydrase serotonin and melatonin increases the production of CA-I, II,; L and D phenylalanine increases the production Of CAI, II, V(A), VII; androgens (including DHEA-dehydroepiandrosterone) increases CA-II, III production.
Administering the compound maybe done but not limited to injection or ingestion. The injection method used maybe intramuscular or intravenous, dissolved in a sterile saline solution, glucose solution, or other commonly administered parenteral solution. The best method of administering the compound will be learned with modest experimentation. The individual subject's response to the compound will be learned through testing for the cell specific enzyme in blood samples taken before and after admiministering the medication and by enzyme levels measured from cell cultures of biopsied tissues from the patient or found in the cerebro-spinal fluid. The goal is to increase or decrease the tissue level of cell specific carbonic anhydrase enzymes from an increased or decreased level in the tissue of a patient to a more normal level. Insofar as the enzyme in the blood is a reflection of the enzyme level in the tissue of a pateint, the blood test may be a sufficient indicator. In addition, other means of measuring enzyme levels that are known to the practitioner maybe employed.
For the use of cell specific carbonic anhydrase enzymes as growth factors, the main objective is to keep the cell specific carbonic at normal levels in the damaged or diseased tissue as an environment for them to differentiate and grow. This can be done by determining first, which cell specific carbonic anhydrase enzymes are present in the diseased or damaged human tissue then administering a pharmacologically effective non toxic amount of one or a combination of one or more compounds that increases the level of one or more cell specific carbonic anhydrase enzymes that is present in the damaged or diseased human tissue. Then maintaining the cell specific carbonic anhydrase enzymes at normal levels. Measuring the level of one or more cell specific carbonic anhydrase enzymes can be done directly from the damaged or diseased tissue. Other methods known can be used by the practitioner. The same procedure is followed as an alternative for stem cell therapy.
The response of the treatment can be assessed by biopsy of the tissues, imaging of the tissues involved which includes but not limited to magnetic Resonance Imaging, assessing the ameloriation of the symptoms of the disease or conditions, radioactive scannings for cancers. Other methods are available for the ordinary person skilled in the art.
Pharmaceutical composition suitable for use in the invention include compositions suitable wherein the active ingredient are contained in an effective amount to achieved the intended purpose. The determination of an effective dose is well within the capability of those skilled in the art.
A therapeutically effective dose refers to that amount of active ingredient that ameliorates the symptoms or condition, the condition being caused by or reflected in the reduced or increased concentration of cell specific carbonic anhydrase enzymes. Therapeutic efficacy and toxicity maybe determined by standard procedures from blood testing, from biopsied tissues, and by other means known to the practitioneer, for comparison with the normal values. The dosage is preferably within the range of circulating concentrations that are efficacious with little or no toxicity. The dosage varies within this range depending upon the dosage form employed, sensitivity of the patient and the route of administration.
The exact dosage will be determined by the practitioner, in light of factors related to the subject that requires treatment. Dosage and administration are adjusted to provide sufficient levels of the active moiety or to maintain the desired effect, which is a near-normal level of the cell specific carbonic anhydrase enzyme. Factors which maybe taken into account include the severity of the increased or reduction extant in the subject, general health of the subject, age, weight and gender of the subject, diet, time and frequency of administration, drug combination(s), reaction, sensitivities, and tolerance/response to therapy. Long acting pharmaceutical compositions may be administered every 3 to 4 days, every week, or once every two weeks depending on the half-life and clearance rate of the particular formulation.
Normal dosage amounts may vary from 0.1 to 100,000 micrograms, up to a total dose of about one gram, depending upon the route of administration. Guidance as to particular dosages and methods of delivery is provided in the literature and generally available to practitioners in the art. Those skilled will employ different formulations to achieve the desired results.
