Detailed investigation of anticancer activity of sulfamoyl benz(sulfon)amides and 1H–pyrazol–4–yl benzamides: An experimental and computational study
摘要:
Cancer is the second leading cause of mortality worldwide. Therapeutic approach to cancer is a multi-faceted one, whereby many cellular/enzymatic pathways have been discovered as important drug targets for the treatment of cancer. A major disadvantage of most of the currently available anticancer drugs is their non-selective cytotoxicity towards cancerous as well as healthy cells. Another major hurdle in cancer therapy is the development of resistance to anticancer drugs. This necessitates the discovery of new molecules with potent and selective cytotoxic activity towards only cancerous cells, with minimum or no damage to the normal/healthy cells. Herein we report detailed investigation into the anticancer activity of sulfamoyl benz(sulfon)amides (1a-1g, 2a-2k) and 1H-pyrazol-4-yl benzamides (3a-3j) against three cancer cell lines, breast cancer cells (MCF-7), bone-marrow cancer cells (K-562) and cervical cancer cells (HeLa). For comparison, screening against healthy baby hamster kidney cells (BHK-21) was carried out. All compounds exhibited selective cytotoxicity towards cancerous cells. Cell cycle analysis was carried out using flow cytometry, followed by fluorescence microscopic analysis. DNA interaction and docking studies were also carried out.

Existing AIDS therapies are out of reach for most HIV-infected people in developing countries and, where available, they are limited by their toxicity and their cost. New anti-HIV agents are needed urgently to combat emerging viral resistance and reduce the side effects associated with currently available drugs. Toward this end, LeapFrog, a de novo drug design program was used to design novel, potent, and selective inhibitors of HIV-1 integrase. The designed compounds were synthesized and tested for in vitro inhibition of HIV-1 integrase. Out of the 25 compounds that were designed, and synthesized, four molecules (compounds 23, 26, 43, and 59) showed moderate to low inhibition of HIV-1 integrase for 3'-processing and 3'-strand transfer activities. Nonetheless, these compounds possess structural features not seen in known HIV-1 integrase inhibitors and thus can serve as excellent leads for further optimization of anti-HIV-1 integrase activity.
