摘要: Two new indoloditerpene derivatives asporyzin A (1) and B (2), one C (3), three known related indoloditerpenes JBIR-03 (4), emindole SB (5), emeniveol (6) were isolated from an endophytic fungus Aspergillus oryzae, the marine red alga Heterosiphonia japonica. Their structures unambiguously established by spectroscopic techniques. In addition, all isolates evaluated preliminarily for insecticidal antimicrobial activities in order to probe into their chemical defensive function. Compound 4 was more active against brine shrimp than others, 3 possessed potent activity Escherichia coli.
