The dihydrofolate reductase (DHFR) and thioredoxin reductase (TrxR) enzymes are involved in the process of tumor cell growth and survival. The 4,6-diamino-1,2-dihydro-1,3,5-triazine scaffold is well-established as a useful scaffold for DHFR inhibition, while chalcones have been reported to be inhibitors of TrxR. In this study, 15 novel compounds designed by the structural combination of the 4,6-diamino-1
二氢叶酸还原酶(DHFR)和硫氧还蛋白还原酶(TrxR)酶参与肿瘤细胞的生长和存活过程。众所周知,4,6-二氨基-1,2-二氢-1,3,5-三嗪支架可作为抑制DHFR的有用支架,而据报道查耳酮是TrxR的抑制剂。在这项研究中,成功地合成和表征了通过4,6-二氨基-1,2-二氢-1,3,5-三嗪和查尔酮骨架的结构组合设计的15种新化合物。通过体外酶法评估时,所有化合物均显示出对DHFR和TrxR的双重抑制作用。这些化合物还对MCF-7和HCT116细胞显示出抗增殖活性。更强大的类似物14和15被发现抑制HCT116细胞中的细胞DHFR和TrxR活性。因此,这项研究提供了令人信服的证据,表明14和15可以通过在细胞水平上进行多靶点抑制来发挥其抗癌作用。
