contacts were observed. Their solid-state structures have been analyzed through Hirshfeldsurfaceanalysis, including the evaluation of the different energy frameworks, indicating that the molecular sheets are primarily formed by hydrogen bonds and the stabilization is dominated via the electrostatic energy contribution. These studies are complemented with DFT calculations (B3LYP-D3/def2-TZVP), and a combination
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.
