Synthesis, In Vitro Evaluation, Molecular Docking and DFT Studies of Some Phenyl Isothiocyanates as Anticancer Agents.

BACKGROUND: Isothiocyanates (ITCs) are small molecules that are important in synthetic organic chemistry, but their actual importance lies in their potential as anti-carcinogens. Through this piece of work, an effort was made to assess the anti-cancer activity of some simple ITCs which can be synthesized through easy greener pathways. METHODS: Cell proliferation assay was performed on ovarian cancer cells (PA-1) and non-tumorigenic ovarian epithelial cells (IOSE-364). Furthermore, qRT-PCR for transcript expression levels of Spindlin1 and caspases in ovarian cancer cells and cell cycle analysis was performed. In silico studies were incorporated to understand the mode of ligand-protein interaction, ADME/Toxicity and drug-likeliness parameters. Density functional theory studies have been also been employed on the ITCs to assess their efficiency in anticancer activity. RESULTS: An inexpensive, environmentally benign pathway has been developed for synthesizing a series of ITCs. Among the synthesized ITCs, NC6 showed better cytotoxic effects as compared to its counterparts. Novel findings revealed that NC6 had 5-folds lower transcript expression levels of Spindlin1 and induced caspases 3 and 7 expressions assessed by qRT-PCR in ovarian cancer cells. Furthermore, flow cytometry assay showed the cell cycle arrest at G1/S phase of cell cycle. The molecular docking studies revealed favorable binding affinities and the physiochemical parameters were predicted to be compatible with drug-likeliness. CONCLUSION: The results demonstrated the possibility that small isothiocyanate molecules which can be synthesized by a simple green methodology, can pose as promising candidates for their application as anticancer agents.

Green Synthesis of Bromo Organic Molecules and Investigations on Their Antibacterial Properties: An Experimental and Computational Approach.

A simple, environmentally benign methodology has been developed to synthesize some bromoorganic compounds which have potential as antimicrobial agents. The required compounds were obtained through microwave (MW) irradiation, on-water reactions and using cetyltrimethylammonium tribromide (CTMATB) as the bromine source. The high yield of the product could be achieved within short reaction times, thus representing the main attribute of the present synthetic approach. The compounds were evaluated for in vitro antibacterial activity against Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus and Bacillus subtilis. Further, in silico studies were carried out to elucidate the interactions of the compounds with the bacterial proteins.
