Design, synthesis, and docking of novel thiazolidine-2,4-dione multitarget scaffold as new approach for cancer treatment

Novel thiazolidine-2,4-diones have been developed and estimated as conjoint inhibitors of EGFR(T790M) and VEGFR-2 against HCT-116, MCF-7, A549, and HepG2 cells. Compounds 6a, 6b, and 6c were known to be the dominant advantageous congeners against HCT116 (IC50 = 15.22, 8.65, and 8.80 mu M), A549 (IC50 = 7.10, 6.55, and 8.11 mu M), MCF-7 (IC50 = 14.56, 6.65, and 7.09 mu M) and HepG2 (IC50 = 11.90, 5.35, and 5.60 mu M) mass cell lines, correspondingly. Although compounds 6a, 6b, and 6c disclosed poorer effects than sorafenib (IC50 = 4.00, 4.04, 5.58, and 5.05 mu M) against the tested cell sets, congeners 6b and 6c demonstrated higher actions than erlotinib (IC50 = 7.73, 5.49, 8.20, and 13.91 mu M) against HCT116, MCF-7 and HepG2 cells, yet lesser performance on A549 cells. The hugely effective derivatives 4e-i and 6a-c were inspected versus VERO normal cell strains. Compounds 6b, 6c, 6a, and 4i were found to be the most effective derivatives, which suppressed VEGFR-2 by IC50 = 0.85, 0.90, 1.50, and 1.80 mu M, respectively. Moreover, compounds 6b, 6a, 6c, and 6i could interfere with the EGFR(T790M) performing strongest effects with IC50 = 0.30, 0.35, 0.50, and 1.00 mu M, respectively. What is more, 6a, 6b, and 6c represented satisfactory in silico computed ADMET profile.
