Synthesis, Crystal Structure and Biological Activity of 6-Arylmethyl-7H-thiazolo[3,2-b]-1,2,4-triazin-7-one Derivatives as Antitumor Agents

【摘要】 In order to explore the novel anti-tumor agents, ten 6-arylmethyl-3-aryl-7 Hthiazolo[3,2-b]-1,2,4-triazin-7-ones were designed and synthesized, and the structures were characterized by ¹H-NMR, MS, IR and X-ray single-crystal diffraction analysis. The biological activity results showed that the target compounds exhibited certain inhibitory activity of osteosarcoma cells U2 OS-EGFP. Compounds 6 a, 6 g and 6 j exhibited more than 70% inhibition ratio at the concentration of 50 μmol·L^-1, and especially, the IC50 value of compound 6 j was 11.58 μmol·L^-1. The crystal of 6 h was obtained and analyzed; some related weak interactions were discussed. The molecular docking results showed that the target compounds were supposed to be ERK1/2 inhibitors.更多还原
