A series of 22 quinazolines, pyrido[2,3-d]pyrimidines and their hydroselenite salts were synthesized with the aim of evaluating in vitro their cytotoxicity against PC-3 cell line and their antioxidant properties related to DPPH (1,1-diphenyl-2-picrylhydrazylradical) activity, showing some of them better profile than the respective controls. Three of these derivatives (5d, 6d and 7f) were selected in
合成了一系列 22 种喹唑啉、吡啶并[2,3-d]嘧啶及其亚硒酸盐,目的是在体外评估它们对 PC-3 细胞系的细胞毒性及其与 DPPH(1,1-二苯基- 2-picrylhydrazylradical) 活性,显示其中一些比各自的对照更好的轮廓。选择了这些衍生物中的三个(5d、6d 和 7f)以获得初步见解以建立作用机制。Caspase-3 活性和细胞周期调节研究表明,化合物 6d 引起 caspase-3 水平增加,并以时间依赖性方式伴随细胞周期扰动。
