The synthesis of a series of esters of hycanthone (HC) and 7-hydroxyhycanthone, their antitumor activity, and their antischistosomal effects on HC-sensitive and HC-resistant schistosomes are reported. Binding studies using tritium-labeled HC and hycanthone N-methylcarbamate (HNMC) with calf thymus DNA provided evidence that HNMC but not HC alkylated the DNA. Tritiated HNMC also bound to the DNA of
报道了一系列庚烷酮和7-羟基庚酮的酯的合成,它们的抗肿瘤活性以及它们对HC敏感和HC抵抗性血吸虫的抗血吸虫作用。使用tri标记的HC和庚酮N-甲基氨基甲酸酯(HNMC)与小牛胸腺DNA的结合研究提供了证据,表明HNMC而非HC使DNA烷基化。ti化的HNMC还与暴露于药物的完整HeLa细胞的DNA结合,而在相同条件下,极少的tri化的HC与DNA结合。如方案一所示,先前提出的解释HC的抗血吸虫作用的机制,即药物酯化然后DNA烷基化,也适用于药物的抗肿瘤作用。
