Description
Napyradiomycin A
1 is a fungal metabolite originally isolated from
C. rubra and has diverse biological activities. It is active against
S. aureus,
M. luteus,
B. anthracis,
C. bovis, and
M. smegmatis (MICs = 1.56-12.5 μg/ml). Napyradiomycin A
1 is an estrogen receptor antagonist (IC
50 = 4.2 μM in rat uterine homogenates). It also inhibits mitochondrial NADH:ubiquinone oxidoreductase (complex I) and succinate:ubiquinone oxidoreductase (complex II) activities in bovine heart homogenates (IC
50s = 20 and 9.7 μM, respectively).
