In an attempt to generate compounds with superior bioactivity and reduced toxicity, 12 carbamates of 4′-demethyl-4-deoxypodophyllotoxin, N-(1-oxyl-4′-demethyl- 4-deoxypodophyllic)-α-amino acids amides, were synthesized and evaluated for antiproliferative activity and cell cycle effects. These synthesized compounds proved to be more hydrophilic, as well as improved or comparable in vitro cytotoxicities
为了产生具有优良生物活性和降低的毒性的化合物,合成了12个氨基甲酸酯的4'-脱甲基-4-脱氧鬼臼毒素,N-(1-氧基-1'-脱甲基-4-4-脱氧鬼臼酸)-α-氨基酸酰胺。并评估其抗增殖活性和细胞周期效应。与母体DPT或抗癌药VP-16相比,这些合成的化合物被证明对四种细胞系(A-549,HeLa,SiHa和HL-60)具有更强的亲水性,以及改善的或相当的体外细胞毒性。此外,流式细胞仪分析表明,N-(1-氧基-1'-脱甲基-4-脱氧鬼臼酸)-d -α-次甲基酰胺(15f)诱导了A-549细胞在G2 / M期的细胞周期停滞。
