Napyradiomycin A1is a fungal metabolite originally isolated fromC. rubraand has diverse biological activities.1,2It is active againstS. aureus,M. luteus,B. anthracis,C. bovis, andM. smegmatis(MICs = 1.56-12.5 μg/ml).1Napyradiomycin A1is an estrogen receptor antagonist (IC50= 4.2 μM in rat uterine homogenates).2It also inhibits mitochondrial NADH:ubiquinone oxidoreductase (complex I) and succinate:ubiquinone oxidoreductase (complex II) activities in bovine heart homogenates (IC50s = 20 and 9.7 μM, respectively).3

(+)-Geodin is a fungal metabolite. It increases the fibrinolytic activity of bovine aortic endothelial cells (BAECs) when used at concentrations ranging from 50 to 150 μM. (+)-Geodin (1-100 μg/ml) also increases 2-deoxyglucose uptake by rat adipocytes.
4',2-Dihydroxy-4,6-dimethoxydihydrochalcone, an estrogen agonist, exhibits a significant binding affinity for the estrogen receptor in bovine uterine tissue, with an IC50 value of 15 μM.
