A fused ring system compound is disclosed that contains an epoxide group on one side of the fused rings and an enediyne macrocyclic ring on the other side of the fused rings. The compounds have DNA-cleaving, antimicrobial and tumor growth-inhibiting properties. Chimeric compounds having the fused ring system compound as an aglycone bonded to (i) a sugar moiety as the oligosaccharide portion or (ii) a monoclonal antibody or antibody combining site portion thereof that immunoreacts with target tumor cells are also disclosed. Compositions containing a compound or a chimer are disclosed, as are methods of preparing a compound.

synthesis and chemical properties of designed enediynes related to dynemicin A. These modelsystems are equipped with triggering devices at C-3 of the aromatic nucleus. The design of these compounds (1 and 2) was based on the hypothesis that a C-3 phenolic group generated in situ would be capable of promoting epoxide opening and subsequent Bergman cycloaromatization according to the dynemicin A cascade
继续上一篇文章的主题,本文描述了与动力霉素 A 相关的设计烯二炔的合成和化学性质。这些模型系统在芳环的 C-3 处配备了触发装置。这些化合物(1 和 2)的设计基于这样一个假设,即原位生成的 C-3 酚基能够促进环氧化物开放和随后的 Bergman 环芳构化,根据 dynemicin A 级联
