The N alpha-(2-chloroethyl)-N-nitrosocarbamoyl derivatives of H-Pro-Lys(X)-Pro-Val-NH2 (X: tert-butyloxycarbonyl, formyl, (2-chloroethyl)nitrosocarbamoyl) were synthesized. It was found that the bis-substitution of the urea N3 in these derivatives does not decrease the antitumor activity influenced mainly by the nature of the carrier molecule as a whole.
合成了H-Pro-Lys(X)-Pro-Val-NH2的Nα-(2-氯乙基)-N-亚硝基氨基甲酰基衍生物(X:叔丁氧羰基,甲酰基,(2-氯乙基)亚硝基氨基甲酰基)。发现这些衍生物中的尿素N 3的双取代不会降低主要受载体分子整体性质影响的抗肿瘤活性。
