Biotransformation of bromosesquiterpenes by marine fungi
摘要:
Biotransformation of bromosesquiterpenes was investigated with two types of fungi, Rhinocladiella atrovirens NRBC 32362 and also Rhinocladiella sp. K-001, isolated from the Okinawan brown alga Stypopodium zonale. R. atrovirens NRBC 32362 converted aplysistatin 1 into three compounds 5 alpha-hydroxyaplysistatin 4, 5 alpha-hydroxyisoaplysistatin 5 and 9 beta-hydroxyaplysistatin 6. Transformation of 1, palisadin A 2 and 12-hydroxypalisadin B 3 by Rhinocladiella sp. K-001 gave two compounds, 3,4-dihydroaplysistatin 7 and 9,10-dehydrobromopalisadin A 8. (C) 2009 Elsevier Ltd.
