As a continuation of earlier works, a series of novel quinazolinone derivatives (5a-s) were synthesized and evaluated for their in vitro anti-HBV and anti-hepatocellular carcinoma cell (HCC) activities. Among them, compounds 5j and 5k exhibited most potent inhibitory effect on HBV DNA replication in both drug sensitive and resistant (lamivudine and entecavir) HBV strains. Interestingly, besides the
作为早期工作的延续,合成了一系列新颖的喹唑啉酮衍生物(5a - s),并对其体外抗HBV和抗肝癌细胞(HCC)活性进行了评估。其中,化合物5j和5k在药物敏感性和耐药性(拉米夫定和恩替卡韦)HBV菌株中均表现出对HBV DNA复制的最强抑制作用。有趣的是,除了抗HBV效应,化合物5k还可以显着抑制HepG2,HUH7和SK细胞的增殖,IC 50值分别为5.44、6.42和6.75μM ,表明其潜在的抗HCC活性。值得注意的是,5k的体外抗HCC活性比阳性对照5-氟尿嘧啶和索拉非尼更有效。进一步的研究表明,化合物5k可通过剂量依赖性上调Bad和Bax表达并降低Bcl-2和Bcl-xl蛋白水平来诱导HepG2细胞凋亡。考虑到有效的抗HBV和抗HCC作用,化合物5k可能是开发针对HBV感染和HBV诱导的HCC的新型治疗剂的有希望的线索。
