Objective: The objective of this study was to prove that cow urine distillate (CUD) is a bioenhancer for antimicrobial activity and antiproliferative activity, redistilled CUD (RCUD) as an anticlastogen agent. Methods:The antimicrobial activity of rifampicin with CUD at different concentrations was determined against pathogenic Escherichia coli by well puncture method. The Penicillin and ciprofloxacin in combination with CUD at different/increasing concentrations against pathogenic E. coli culture were also determined by disc diffusion method. Sulforaphane (ACA) as an anticancer agent was extracted from cruciferous vegetables and purified by high-performance liquid chromatography. The Breast cancer cell lines (MCF-7) were treated with anticancer agents along with CUD in increasing concentrations. The anticlastogenic activity of RCUD in human peripheral lymphocytes was tested with clastogens such as manganese dioxide and hexavalent chromium.Results: CUD showed to enhance the antimicrobial activity of rifampicin with 20 µl concentration by well puncture method; penicillin with increasing concentration of up to 80 µl and ciprofloxacin up to 80 µl, respectively, by disc diffusion method. The rate of degeneration of breast cancer cell lines (MCF-7) was increased with increasing concentration of CUD. Clastogen (MnO 2 ) of 10 µl with 200 µl of RCUD showed effective anticlastogenic activity in agarose gel electrophoresis as the activity of clastogen decreased with increasing concentration of RCUD. Conclusion:CUD acts as a bioenhancer to increase antimicrobial and antiproliferative activity. RCUD showed a high level of anticlastogenic activity toward clastogen. Thus, cow urine is found to have special properties that can be used in combination with different therapeutic agents to cure several diseases such as tuberculosis, leprosy, and cancer. Further in vivo and clinical studies are required to confirm its therapeutic efficacy.

Objective: This study is designed to hunt for the presence of bioactive compounds from three marine sponges collected from Kovalam.Methods: Zoochemical analysis is performed to screen for the presence of secondary metabolites. Based on those results, only two sponges which showed a significant presence of secondary metabolites has been subjected to gas chromatography-mass spectrometry (GC-MS) analysis to identify the unknown chemical compounds present in those sponges.Results: On analyzing the results, two sponges, namely, Dysidea herbacea and Sigmadocia pumila, has shown a significant presence of secondary metabolites while the third sponge Acanthella elongata have shown moderate presence of secondary metabolites. Since the first two sponges results are remarkable, these two samples have been subjected to GC-MS analysis to separate and identify the unknown chemical compounds present in the sample. Conclusion:Samples, namely, D. herbacea and S. pumila, indicated the presence of several components. From both the sponges, eleven different secondary metabolites were identified by GC-MS. Most of these compounds are widely used in cosmetic, pharmaceutical, and other industries and therefore a vital source for industrial biotechnology and related products in healthcare and skincare.

Objective: The main focus of this study is to screen the marine sponges for potent free radical scavenging activity. Methods:Various methods such as 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS), and ferric reducing antioxidant power (FRAP) assay are employed to ascertain the antioxidant properties of marine sponges namely Dysidea herbacea and Sigmadocia pumila.Results: On analyzing, the result of ABTS assay D. herbacea and S. pumila exhibited almost equal antioxidant properties. While calculating the inhibitory concentration 50% value for DPPH assay, the Sample 1 and 2 has an IC of 655.49 and 826.739 µl, respectively, and in FRAP assay, the Sample 1 and 2 has an IC of 67.587 and 74.57 µg, respectively. Conclusion:Overall from this assay, D. herbacea revealed slightly better antioxidant activity when compared to S. pumila, also which in future may serve as a better source to fight against various diseases.

Identifying new targets and new drugs has always been a daunting task, especially in cancer research. This studyexamines the binding interaction and the drug-likeness properties of small molecules derived from marine sponge Dysideaherbacea to breast cancer receptors: epidermal growth factor receptor and estrogen receptor. The receptor’s interaction with the ligand was evaluated using the Schrodinger Glide package, and affinities were assessed based on the glide score. Ligand molecules that have higher binding affinity were evaluated further for their ADMET properties using Molinspiration.We found multiple ligands binding to these targets; however, Pyridine 3 carboxyamidewas found to have binding affinity to both the receptors. Compared to the other small molecules,further simulation studies could be taken up to ascertain its structural dynamics and ensuing in-vitro experiments that could prove growth inhibition of breast cancer cells.

Objective: The present research focused on amplification of protease gene from Bacillus strain which was then assessed for maximal enzyme activity.Methods: A putative Bacillus strain was isolated from soil, inoculated into protease production media, and optimized with appropriate pH and temperature conditions for maximal enzyme activity. Genomic DNA was isolated from the strain and amplified the fragment by polymerase chain reaction (PCR) using gene-specific primers for protease. The fragment is then ligated into a T/A cloning vector and transformed into calcium chloridetreated competent Escherichia coli DH5α cells. The plasmids were then isolated and confirmed the presence of the gene.Results: A specific amplification of 1.1 kb was observed following PCR. The amplified product includes the coding sequence and a signal peptide sequence of the protease gene. After cloning with T/A cloning vector pTZ57R/T and transformed into E. coli DH5α competent cells, the recombinant plasmid was selected using blue-white selection. Plasmid DNA isolated from the recombinant strains and confirmed the presence of a gene of interest using PCR and quantified by an assay for maximal protease activity. The optimum pH was found to be 10.1 and giving an activity of 21.566 international unit (IU)/ml, and the optimum temperature was found to be on 60°C giving an activity of 38.708 IU/ml. Conclusion:Amplification of protease gene by PCR isolated from Bacillus strain and optimization of pH and temperature conditions for the assessment of subtilisin Carlsberg produced by it. Subtilisin which is protein engineered can be used in commercial products such as stain cutter, dishwashing detergents, cosmetics and food processing, and contact lens cleaner.
