The preparation and the cytotoxic properties of new derivatives of the planar pyrido[3′,2′:5,6]thiopyrano-[4,3-c]pyrazole system, carrying an arylic side group in the 1 or 2 positions, are described. The novel substituted derivatives were obtained by reaction of suitable arylhydrazines with the appropriate key intermediate 3-hydroxymethylene-2,3-dihydrothiopyrano[2,3-b]pyridin-4(4H)-ones. Moreover
描述了平面吡啶基[3',2':5,6]硫代吡喃基-[4,3- c ]吡唑系统的新衍生物的制备和细胞毒性,该衍生物在1或2位带有芳基侧基。通过使合适的芳基肼与合适的关键中间体3-羟基亚甲基-2,3-二氢硫代吡喃并[2,3- b ]吡啶-4-4 (4 H)-反应得到新的取代衍生物。此外,据报道制备了2-羧酰胺基苯基衍生物,其是通过与异氰酸苯酯反应从先前获得的吡啶并[3',2':5,6]硫代吡喃并[4,3- c ]吡唑核完成的。通过体外评估所有新化合物的抗增殖能力 在人类肿瘤细胞系(HL-60和HeLa)上进行检测。
