Study on the modification and anti-tumor activity of silybin derivatives for CDK4/6 targeted / 药学学报

ABSTRACT

By using computer-aided drug design, the activities group model which CDK4/6 inhibitors on the market were introduced to silybin C-7, and a series of silybin derivatives were designed and synthesized, and the structure was confirmed by MS, 13C NMR and 1H NMR. The in vitro antitumor activity evaluation of the target compound was carried out by MTT method, and the in vitro anti-tumor activity was carried out in human hepatocellular carcinoma cells (HepG-2). Experimental results show that all compounds are higher than the activity of the parent silybin, of which compound I1 has a certain inhibitory effect on human HepG-2 cells, which is worth further study.
