Prostaglandin E1 (PGE1) is a vasoactive prostaglandin and an active metabolite of dihomo-gamma-linolenic acid (DGLA, Cay-90230). It is formed from DGLA by COX-1 and COX-2. PGE1 is an agonist of the PGE2 (Cay-14010) receptor subtypes EP1, EP2, EP3, and EP4, and the IP receptor (Kis = 36, 10, 1.1, 2.1, and 33 nM,...

1-NM-PP1 is a cell permeable inhibitor of kinases that have been mutated, by a single base substitution, to become 'analog sensitive' (as), as compared to the wild-type kinase. 1-NM-PP1 was first developed to optimally inhibit v-Src-as1, with an I338G substitution, preferentially over v-Src (IC50 = 4.2 nM versus 28...

The cytochalasins are cell-permeable fungal metabolites that inhibit actin polymerization. This interferes with such diverse processes as cell movement, growth, phagocytosis, degranulation, and secretion. Cytochalasin D is a cell-permeable inhibitor that binds actin filaments, but not actin monomers, to inhibit...

Bisindolylmaleimide V (BIM V) is a weak inhibitor of protein kinase C (PKC) demonstrating an IC50 value >100 µM. While effectively inactive as a PKC inhibitor, BIM V blocks the activation of mitogen-stimulated protein kinase p70s6k/p85s6k (S6K) in vivo with an IC50 value of 8 µM.Formal Name:...
