Gilvocacin V(1),C27H28O9,m.p. 264 约 267 摄氏度(分解),吉沃卡星 M(2),C26H26O9,m.p. 264 245 约 248 摄氏度(分解),是由 Streptomyces gilvotanareus 产生的新型抗肿瘤抗生素。 gilvocacins 的结构已通过化学降解、核磁共振和质谱确定。它们具有苯并萘吡喃酮系统,呋喃糖部分通过 C-C 糖基键连接到该系统。
Gilvocarcin V(1), C27H28O9, m.p. 264 approximately 267 degrees C (dec.), and gilvocarcin M(2), C26H26O9, m.p. 245 approximately 248 degrees C (dec.), are new antitumor antibiotics produced by Streptomyces gilvotanareus. The structure of gilvocarcins has been determined by chemical degradation, nmr and mass spectra. They have a benzonaphtopyran-one system, to which the furanose moiety is linked through a C-C glycosyl bond.
