YM-202204, a new antifungal antibiotic produced by marine fungus Phoma sp.
A new antifungal antibiotic, YM-202204 (1), was found in the culture broth of marine fungus Phoma sp. Q60596. The structure of 1 was determined by several spectroscopic experiments as a new lactone compound. This antibiotic exhibited potent antifungal activities against Candida albicans, Cryptococcus neoformans and Aspergillus fumigatus, and also inhibited glycosyl-phosphatidyl-inositol (GPI)-a...
متن کاملNeuraminidase inhibitory polyketides from the marine-derived fungus Phoma herbarum.
Two new polyketides, arthropsadiol C (1) and massarilactone H (2), together with six known derivatives (3-8) were isolated from the culture broth of the marine-derived fungus Phoma herbarum. Their structures were elucidated on the basis of spectroscopic methods, including 2D NMR techniques. Compounds 2, 4, 5, and 8 showed moderate neuraminidase inhibitory activity with IC(50) values ranging fro...
متن کاملNew Butyrolactone from a Marine-derived Fungus Aspergillus Sp
Four compounds that belong to two structure types, namely dibenzylbutyrolactone and sesterterpenoids, were obtained from the extract of the strain Aspergillus sp. (2P-22), isolated from a marine sponge, Cliona chilensis. Among them, compound 1 was identified as new, namely butylrolactone-VI. The structures of these compounds were characterized on the basis of spectroscopic data. Biological acti...
متن کاملBioactive Diphenyl Ethers and Isocoumarin Derivatives from a Gorgonian-Derived Fungus Phoma sp. (TA07-1)
Three new diphenyl ether derivatives-phomaethers A-C (1-3) and five known compounds-including a diphenyl ether analog, 2,3'-dihydroxy-4-methoxy-5',6-dimethyl diphenyl ether (4); and four isocoumarin derivatives, diaportinol (5), desmethyldiaportinol (6), citreoisocoumarinol (7), and citreoisocoumarin (8)-were isolated from a gorgonian-derived fungus Phoma sp. (TA07-1). Their structures were elu...
متن کاملPretrichodermamides D–F from a Marine Algicolous Fungus Penicillium sp. KMM 4672
Three new epidithiodiketopiperazines pretrichodermamides D-F (1-3), together with the known N-methylpretrichodermamide B (4) and pretrichodermamide С (5), were isolated from the lipophilic extract of the marine algae-derived fungus Penicillium sp. KMM 4672. The structures of compounds 1-5 were determined based on spectroscopic methods. The absolute configuration of pretrichodermamide D (1) was ...
