| pubmed-article:8978857 | pubmed:abstractText | Phomactins, natural products isolated from the culture broth of marine fungus Phoma sp., were found to be active as PAF antagonists. This unique carbon skeleton led us to investigate the structure-activity relationship demonstrating that the lipophilicity at C-(7-8), acetoxy, (methoxycarbonyl)oxy, and 3-isoxazolyloxy substitution at C-20, and 2-beta-OH configuration at C-2 are all required for the enhancement of inhibitor activity. | lld:pubmed |
