Mer-NF5003F is a sesquiterpene originally isolated from Stachybotrys with diverse biological activities.1,2,3 It inhibits avian myeloblastosis virus (AMV) protease (IC50 = 7.8 μM).1 Mer-NF5003F inhibits sialyltransferase 6N (ST6N), ST3O, and ST3N (IC50s = 0.61, 6.7, and 10 μg/ml, respectively), as well as fucosyltransferase (IC50 = 11.3 μg/ml).2 It is active against herpes simplex virus 1 (HSV-1) in vitro (IC50 = 4.32 μg/ml).3 Mer-NF5003F is also active against the multidrug-resistant P. falciparum strain K1 (IC50 = 0.85 μg/ml). | [Uses]
Mer-NF5003F (Stachybotrydial; F 1839M), a sesquiterpene isolated from Stachybotrys, inhibits avian medulloblastoma virus (AMV) protease (IC50=7.8 μM). Mer-NF5003F inhibits sialyltransferase 6N (ST6N), ST3O, and ST3N (IC50=0.61, 6.7, and 10 μg/mL, respectively), and fucosyltransferase (IC50=11.3 μg/mL). Mer-NF5003F has in vitro activity against herpes simplex virus HSV-1 (IC50=4.32 μg/mL) and multidrug-resistant Plasmodium falciparum K1 strain (IC50=0.85 μg/mL). | [References]
