ZLJ-6 is a dual inhibitor of COX and 5-lipoxygenase (5-LO) (IC50 = 0.73, 0.31, and 0.99 µM for COX-1, COX-2, and 5-LO, respectively, in whole blood). It reduces carrageenin-induced paw edema (inflammation) in rats and acetic acid-induced abdominal constriction (pain) in mice without causing gastrointestinal ulcers,...

Fumonisin B2 (FB2) is a mycotoxin that has been found in F. moniliforme. It is cytotoxic against a panel of seven rat hepatoma cell lines (IC50s = 3-50 µg/ml), as well as MDCK cells (IC50 = 2 µg/ml). FB2 (125-1,000 µM) is also cytotoxic to primary rat hepatocytes and induces hepatocyte nodule formation, a marker of...

The cytochalasins are cell-permeable fungal metabolites which inhibit actin polymerization. This interferes with such diverse processes as cell movement, growth, phagocytosis, degranulation, and secretion. Cytochalasin A is an oxidized analog of cytochalasin B that uniquely inhibits HIV-1 protease (IC50 = 3 µM)....

PPM-18 is a naphthoquinone compound that inhibits NF-kappaB activation in vitro and in vivo (IC50 = 5 µM). Through this action, it inhibits the expression of inducible nitric oxide synthase (iNOS) in macrophages treated with lipopolysaccharide and suppresses inflammation and sepsis.Formal Name:...

Fatty acid amide hydrolase (FAAH) degrades N-acyl ethanolamines (NAEs), including the endocannabinoid arachidonoyl ethanolamide (AEA). PF-3845 is a potent, selective, and irreversible inhibitor of FAAH (Ki = 0.23 µM). It covalently binds FAAH on Ser241 at the catalytic site, resulting in prolonged elevation of AEA...
