reported pyridinyl phosphine oxides as antitumor agents, we targeted the commercially available C2-axial chiral organophosphine ligand catalysts, such as 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (BINAP) 1 and 2,2′,6,6′-tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine (P-Phos) 2 as a convenient source for producing organophosphine oxides as antitumor leads. Their corresponding chiral and racemic
继我们先前报道的吡啶基膦氧化物作为抗肿瘤剂之后,我们针对了市售的C 2轴手性有机膦配体催化剂,例如2,2'-双(二苯基膦基)-1,1'-联萘基(BINAP)1和2, 2',6,6'-四甲氧基-4,4'-双(二苯基膦基)-3,3'-联吡啶(P-Phos)2作为生产有机膦氧化物作为抗肿瘤导线的方便来源。它们相应的手性和外消旋双膦氧化物3和4通过用过氧化氢的简单氧化步骤可以容易地获得β-环糊精,并且报道了它们对人肝细胞癌Hep3B细胞系的抗肿瘤活性。我们发现,化合物3个比的显示更强的抗肿瘤活性的4,其中轴手性不能提高它们的活性。进一步的无胸腺裸鼠Hep3B异种移植模型证明了3的诱人的体内抗肿瘤潜力。
