A COMPOSITION (RUCD) FOR PROTECTING AND/OR REPAIRING DNA FROM OXIDATIVE DAMAGES AND A METHOD THEREOF Field of the present invention

A composition useful for protecting and/or repairing DNA from oxidative damages said composition comprising redistilled cow's urine distillate (RCUD) having components benzoic acid, and hexanoic acid, with ammonia content of the composition ranging between 5-15mg/L, and optionally along with anti-oxidants; and a method of protecting and/or repairing DNA from oxidative damages using composition of claim 1, said method comprising steps of estimating the amount of folded DNA in a sample, mixing the said composition to the said DNA either before or after the exposure of the DNA to the oxidatively DNA-damaging agent, and determining percentage folded DNA in the mixture showing protection and/or repair of DNA from oxidative damages. Background and prior art of the present invention In Veda, the products of cow have been compared with the nectar (Rig- Veda 10.15 pp. 47). In Ayurveda cow's urine is one of the ingredient of Panchagavya. According to Susrut, Cow's urine has several medicinal properties (45/221, pp-61, 72, 220, 221). Its properties are also described by Charak (Solka-100 pp. 72). Cow's urine is extensively used in Ayurveda for purifying certain materials which otherwise possess toxic properties (pp-73). However, the literature and scripture does not mention urine or its distillate as a protector of cells from DNA damage and chromosomal aberration. To investigate the property of cow urine distillate, the applicants obtained Kamdhenu Ark which is cow urine distillate prepared and marketed by the Govigyan Anusandhan Kendra (GVAK), Nagpur (India). This is the urine distillate suggested for oral ingestion to improve the general health and to control weight gain, oedema, stomach ache, indigestion, skin disease, cardiac problem etc. It is stated in the production process of Kamdlienu Ark that the cow's urine should be fresh as well as free of ammonia. Experiments carried out in NEERI revealed that storage of cow's urine results in formation of ammonia as could be seen from the following Table 1. Table 1 : Ammonia concentration in cows urine

The previous work of the applicants was on oxidative damage of the cigarette smoke can be prevented by vitamin C. The Authors demonstrated that the exposure of sub clinical or marginal vitamin C -deficient guinea pigs to cigarette smoke causes oxidation of plasma proteins as well as extensive oxidation degradation of the lung microsomal proteins. Further, cigarette exposure also induces Peroxidation of microsomal lipids as evidenced by the formation of conjugated dienes, malondialdehyde, and fluorescent pigment. However, complete protection against protein damage and lipid Peroxidation occurs when the guinea pigs are fed vitamins. Also, cigarette induced damage of proteins and lipid is reversed after discontinuation of cigarette smoke exposure accompanied by ascorbate therapy. The results if extrapolated to^*humans, indicate that comparatively large doses of vitamin C may protect the smokers from cigarette smoke - induced oxidative damage and associated degenerative diseases.

A pharmaceutical composition comprising antioxidants containing cow urine distillate in an amount effective' to protect DNA damage is disclosed. The antioxidants can be volatile fatty acid.

The invention related to a noble use of redistilled low ammonia containing cow's urine distillate for DNA damage protection. DNA, one of the most critical cellular targets for hazardous chemicals and wastes, may get damaged following exposure by alteration of bases of disruption of sugar phosphate backbone.

When DNA damage occur in cells, the genes responsible for genomic integrity and DNA damage repair mechanism get induced as a result of which cell cycle gets arrested at Gl stage. Thereafter, the damaged DNA is repaired following which the arrested cell cycle resumes and the cell progresses into S-phase (DNA synthesis). However, if the damage could not be repaired then the same gene, which normally carries out the repair, induce the cell to go for apoptosis (programmed cell death) thereby maintaining the system free from defective cells. The present invention has direct implication in facilitating the damage repair caused by DNA damaging chemical such as hydrogen peroxide (H₂O₂), actinomycin-D and manganese-dioxide (MnO₂).

The ammonia originates from urea present in cow's urine following enzymatic hydrolysis by the enzyme urease present in number of microorganisms. Though ammonia is toxic to human health, the dose at which Kamdhenu Ark is consumed (5 ml at a time) is not likely to exert any adverse health effect or healthy individuals. However, its removal from the Ark is desirable before human consumption at least for the sensitive population. Therefore Kamdhenu Ark procured from GVAK, Nagpur was treated with orthophosphoric acid following which distillation was again carried out. The redistillation process require addition of 10-25 ml of (85%) Orthophosphoric acid (AR grade) to 400 ml of K-Ark to bring the pH to less than 2 which will immobilize ammonia in the residue. The redistillation was performed at around 100°C and the distillate was tested for ammonia. It was observed that the ammonia level in the distillate varied between 5-15 mg/1. The removal of ammonia resulted in disappearance of the manifestation of cytotoxicity, which was observed with ammonia containing K-Ark prior to redistillation. The redistilled Kamdhenu-Ark (RCUD) with an ammonia level varying between 5 and 15 mg/1 was used for subsequent experiments. The present invention was the result of planned experiment which demonstrated the property of Kamdhenu-Ark as the protector of DNA damage to cells exposed to DNA damaging chemicals. Cow's urine, one of the components of Panchagavya, is considered to cause weight loss reversal of certain cardiac problems, indigestion, stomach ache, oedema, etc. However, its role in preventing DNA damage has not been mentioned anywhere in the literature and scriptures. Therefore the applicant considered worthwhile to determine the efficiency of redistilled Kamdhenu Ark to protect DNA damage in cells exposed to DNA damaging chemicals in vitro. The applicants also analyzed the redistilled Kamdhenu Ark using gas chromotography-mass spectrography (GC-MS) and identified the components which are likely to act as anti-oxidants to behave like other known antioxidants which are known to protect DNA damage. The invention relates new uses of cow's urine distillate as a protectant of cellular DNA damaging chemicals such as actinomycin-D, hydrogen peroxide and manganese dioxide.

The compounds identified in redistilled cow's urine acts as antioxidants which are known to protect cells from DNA damage.

Brief description of the accompanying drawing Figure 1 represents the detector response of GCMS following injection of redistilled

Kamdhenu Ark.

This invention is the result of a search of antioxidants of natural origin with a property to protect DNA damage in cells exposed to DNA damaging chemicals. In this endeavour, Kamdlienu Ark was prepared by distilling the urine of specially raised cows on diets containing special herbs as indicated in ancienk scriptures and literature. These cows were raised at GVAK, Deolapar (Nagpur District) under the strict supervision of the inventors from GVAK, Nagpur. The distillate so obtained (around 400 ml /batch), was redistilled by reducing the pH of the distilled Ark to less than 2 by the addition of 10-25 ml of (25%) orthophosphoric acid (AR grade). The redistilled and modified Ark was used for all the experiments conducted subsequently NEERI.

Examples hi the next step, protection of DNA damaging action caused by actinomycin -D, H 0₂, MnO₂ by Kamdhenu Ark was demonstrated. In this endeavor, the applicants experimented with the DNA damaging activities of Actinomycin-D, H₂0₂ and MnO₂ against the polymorphonuclear leucocytes and protection provided by the test component modified Kamdhenu Ark (redistilled cow's urine distillate) following the method described above. These experiments are being described in the following examples. When the polymorphonuclear leucocytes were treated a-priori with redistilled cow's urine distillate as well as at the time of adding the DNA damaging chemicals, protection to DNA damage was observed.

In fact, redistilled cow's urine distillate also had a statistically significant ameliorating effect on the DNA damage caused by the above mentioned DNA damaging agents. The below stated examples are mere elaboration of the invention of the instant Application and should not be construed to limit the scope of the present invention Example - 1

The results are average of five sets of experiments. *P value calculated in comparison to negative control (0.1 % DMSO). K-Ark dosage tested was 60 μl, NS= Not significant. The DNA damage caused by the well known DNA damaging chemical actinomycin - D was statistically significant; P value < 0.001. When cow's urine distillate unmodified Kamdhenu Ark at a volume of 30 μl was simultaneously added with actinomycin D, there was a slight ameliorating effect though the DNA damage observed was statistically significant when compared to control. On the other hand redistilled cow's urine distillate at 30 μl and 60 μl volumes had ameliorating effect on DNA damage when added simultaneously with actinomycin D. The observed anomaly could be attributed to the ammonia content of the unmodified Kamdhenu Ark.

Pretreatment of polymorphonuclear leucocytes (PMNs) with 60 μl of redistilled cow's urine distillate, prior to exposure to Actinomycin -D ,did not result in significant DNA damage showing that redistilled cow urine distillate can protect cells from DNA damage. Post treatment of PMNs with redistilled cow urine distillate 10 min after exposure to actinomycin - D did not result in statistically significant DNA damage.
