10-Phenyl-[11]-cytochalasans from Indonesian mushroom Microporellus subsessilis

Three 10-phenyl-[11]-cytochalasans (4-6), together with three known derivatives (1-3), were isolated from the MeOH extract of the Indonesian mushroom Microporellus subsessilis by bioassay-guided fractionation. The compound 6 and known compounds 1-3 induced immotility in Artemia salina. Compound 6 is the first member of cytochalasin family containing a long-chain fatty acid moiety.
