抗代谢物作为细胞毒药物已经构成了一类特殊的化学物质.例如,新合成的脲衍生物 N-(α-硝基苯)-N-〔4-(5-溴-2-嘧啶氧基)-3-氯代苯〕脲,代号:H0-221.实验中发现它在一个很
Antimetabolites have become a class of specific chemicals as cytotoxic agents. For example, the newly synthesized urea derivative N- (α-nitrophenyl) -N- [4- (5-bromo- ) -3-chlorobenzene] urea, code: H0-221. Experiment found it in a very
