摘要:
The compounds of Formula I are produced by the aerobic fermentation of a fungus of the genus GLIOCLADIUM , ATCC No. 20826. The compounds of Formula I are inhibitors of testosterone 5α-reductase and are useful in the treatment and prevention of acne, seborrhea, female hirsutism and benign prostatic hypertrophy.
摘要:
A series of macrolides is isolated from the fermentation broth of a novel microorganism identified as MA-5000 (ATCC 39476) which morphological analysis reveals to be a strain of Streptomyces hygroscopicus. Based upon analytical studies, the compounds have been found to have the formula: in which R 2 is NH 3 ⊕, R 3 is -O-PO 3 H⊖ and R I is 2-methylpropanoyl, 2-methylbutanoyl or hydrogen, or in which R 1 is 2-methylbutanoyl, R 2 is hydroxy and R 3 is -O-P0 3 H 2 . These compounds have been found to be antifungal and are used in pharmaceutical and industrial (including argricultur- al) applications.
