A series of novel resveratrolâchalcone conjugates have been synthesized. Four compounds were evaluated for their anticancer activity against 60 human cancer cell lines. Among all the derivatives, compound 70 was found to be the most active and showed high selectivity towards certain ovarian cancer, non-small cell lung cancer and breast cancer cell lines with GI50 values in the range of 1.28â34.1 μM. Docking studies were performed to determine the probable binding mode of these compounds in the colchicineâtubulin binding site. A strong H-bonding interaction (1.852 Ã
) was observed with Cys-241 amino acid present in the binding pocket. Thus we believe that compound 70 may possibly be used as a lead for the development of new anticancer agents.

细胞系。在所有衍
生物中,化合物70被发现是最活跃的,且对某些卵巢癌、非小细胞肺癌和乳腺癌
细胞系表现出较高的选择性,其GI50值在1.28-34.1 μM范围内。进行了对接研究,以确定这些化合物在
秋水仙碱-微管结合位点的可能结合模式。在结合口袋中与Cys-241
氨基酸观察到强的氢键相互作用(1.852 Å)。因此,我们相信化合物70可能作为开发新型抗癌剂的先导。
