ICM0301s, New Angiogenesis Inhibitors from Aspergillus sp. F-1491 : II. Physico-chemical Properties and Structure Elucidation

ICM0301A (1), B (2) and their congeners (3-8) were isolated from a culture broth of Aspergillus sp. F-1491 as new angiogenesis inhibitors. Their structures were elucidated by spectroscopic analyses. ICM0301A and B have a substituted decalin skeleton containing two oxirane rings.
