The present invention relates to novel Spergualin related compounds, and a process for producing the same. More particularly, the invention relates to Spergualin related compounds of the formula:
wherein R1 is a lower alkylene group which may be substituted by a hydroxymethyl group; X is a hydrogen atom or a halogen atom; m and n are each 0 or an integer of 1 to 5, and salts thereof, as well as a process for producing the compounds of formula (I) and salts thereof by removing the protecting groups from a protected Spergualin related compounds of the formula:
wherein R1' is a straight chain or branched lower alkylene group which may be substituted by a hydroxymethyl group, the hydroxyl group of which may be protected; R2 is an amino protecting group; R3 is a protected amino group; X, m and n are as defined above.
The compounds of the formula I have anti-tumor activity and can therefore be used as medicaments.
本发明涉及新型 Spergualin 相关化合物及其生产工艺。更具体地说,本发明涉及式如下的 Spergualin 相关化合物:
其中 R1 是可被羟甲基取代的低级亚烷基;X 是氢原子或卤原子;m 和 n 各为 0 或 1 至 5 的整数,及其盐,以及通过从受保护的式 Spergualin 相关化合物中去除保护基团来生产式 (I) 化合物及其盐的工艺:
其中 R1'为直链或支链低级亚烷基,可被羟甲基取代,其羟基可被保护;R2 为
氨基保护基;R3 为受保护的
氨基;X、m 和 n 如上定义。
式 I 的化合物具有抗肿瘤活性,因此可用作药物。
