Isolation and synthesis of caprolactins A and B, new caprolactams from a marine bacterium
摘要:
Two new caprolactams have been isolated from an unidentified Gram-positive bacterium obtained from a deep-ocean sediment sample. Caprolactins A (1) and B (2), which were obtained as an inseparable mixture, are composed of cyclic-L-lysine linked to 7-methyloctanoic acid and 6-methyloctanoic acid, respectively. The structures were proposed using spectroscopic methods and confirmed by synthesis. Both caprolactins A and B are cytotoxic towards human epidermoid carcinoma (KB) cells and human colorectal adenocarcinoma (LoVo) cells and exhibit antiviral activity towards Herpes simplex type II virus.

The present invention relates to a prodrug or a pharmaceutically acceptable salt thereof, comprising a drug linker conjugate D-L, wherein D being a biologically active moiety containing an aliphatic amine group is conjugated to one or more polymeric carriers via dipeptide-containing linkers L. Such carrier-linked prodrugs achieve drug releases with therapeutically useful half-lives. The invention also relates to pharmaceutical compositions comprising said prodrugs and their use as medicaments.
