Design and development of oxobenzimidazoles as novel androgen receptor antagonists

Abstract: Antiandrogens are a novel class of anticancer agents that inhibit cancer cell proliferation and induce apoptosis in various cell lines. To find the lead compound from the oxobenzimidazole derivatives, receptor-ligand docking studies were initially performed using Schrodinger software. The best fit molecules were synthesized and characterized through IR, 1H-NMR, 13C-NMR and HRMS analyses. The structure of compound (9b) was further confirmed by single-crystal XRD analysis. The cell viability of the compounds was determined by MTT assay to find IC50 values against prostate cancer and breast cancer cell lines (PC-3, LNCaP, MCF-7 and MDA-MB-231). The ADME/T property studies were performed to rationalize the inhibitory properties of these compounds. It can be concluded from the study that 9b is the most active compound from the series against PC-3 and LNCaP cell lines.

Synthesis of novel 1,3-thiazin-4-ones by acetylene diester cyclization and their anticancer activities

Abstract: GRAPHICAL ABSTRACT ABSTRACT A novel series of 1,3-thiazin-4-one derivatives containing a piperidyl ring (7–16) were designed and synthesized efficiently by thioamide and acetylene diester cyclization reaction via aminolysis of the ester group and the elimination of an alcohol molecule. The structures of all the novel compounds were established by their FTIR, Mass, 1H NMR, and 13C NMR spectral techniques. The newly synthesized compounds (7–16) were studied for their in vitro anticancer activity against human liver cancer cell lines Hep G2 using MTT assay. The IC50 values of the tested compounds were ranging in between 7.48 ± 0.71 and 56.57 ± 1.37 µM. Further, the apoptosis evaluation by the mitochondrial membrane potential using JC-1 dye was carried out and the results are in good agreement with the cytotoxicity studies.
