| biotransformation of dehydroepiandrosterone (dhea) with penicillium griseopurpureum smith and penicillium glabrum (wehmer) westling. | microbial transformation of dehydroepiandrosterone (dhea, 1) using penicillium griseopurpureum smith and penicillium glabrum (wehmer) westling has been investigated. neither fungi had been examined previously for steroid biotransformation. one novel metabolic product of dhea (1) transformed with p. griseopurpureum smith, 15α-hydroxy-17a-oxa-d-homo-androst-4-ene-3,17-dione (5), was reported for the first time. the steroid products were assigned by interpretation of their spectral data such as (1) ... | 2010 | 20600202 |
