The synthesis and tumor necrosis factor (TNF)-α production enhancing activity of substituted 3'-methyl-thalidomides on human leukemia cell line HL-60 stimulated with 12-O-tetradecanoyl-phorbol 13-acetate (TPA) are described. Though the introduction of an electron-donating amino group at the phthaloyl moiety of α-methylthalidomides enhanced the activity, substituted α-methylthalidomides showed decreased stereoselectivity as compared to that of non-substituted α-methylthalidomide. The data indicates that the TNF-α production enhancing activity of thalidomide derivatives depends on both the electronic-state of substituents at the fused benzene ring and the stereochemistry of the glutarimide moiety.
描述了替代的3'-甲基类地塞米松对用12-O-四癸酰基-佛波醇13-醋酸(TPA)刺激的人类白血病细胞系HL-60的合成及肿瘤坏死因子(TNF)-α产生增强活性。尽管在α-甲基类地塞米松的邻苯二甲酰基部分引入电子给体氨基团增强了活性,但与未替代的α-甲基类地塞米松相比,替代的α-甲基类地塞米松的立体选择性有所降低。数据表明,类地塞米松衍生物的TNF-α产生增强活性依赖于融合苯环上取代基的电子状态以及戊二酰亚胺部分的立体化学。
