oxidation product of cannabidiol, inhibits the catalytic activity of topoisomerase II but without inducing DNA strand breaks or generating free radicals, and unlike many fused-ring quinones exhibits minimal cardiotoxicity. Thus, monocyclic quinones have potential as anticancer agents, and investigation of the structural origins of their biological activity is warranted. New syntheses of cannabidiol and (±)-HU-331
大麻二酚的直接氧化产物单环1,4-苯醌HU-331抑制拓扑异构酶II的催化活性,但不诱导DNA链断裂或产生自由基,与许多稠环醌不同,其心脏毒性最小。因此,单环醌具有作为抗癌剂的潜力,因此有必要对其生物学活性的结构来源进行研究。本文报道了大麻二酚和(±)-HU-331的新合成。集成的合成方案提供了多种多取代的间苯二酚衍生物。许多相应的新型2-羟基-1,4-苯醌衍生物是拓扑异构酶II催化活性的有效抑制剂,比HU-331更重要,其单萜单元被3-环烷基单元取代后,其细胞系的抗增殖特性增强,IC50值延伸至1 mM以下,并且溶液的稳定性高于HU-331。确定了与HU-331相关的醌类主要药效基团。选定的单环醌显示出开发新的抗癌药的潜力。
