Cloprostenol is a synthetic PGF2α analog and a potent FP receptor agonist. (+)-15-epi Cloprostenol is the 15(S), or 15β-hydroxy enantiomer of (+)-cloprostenol. This epimer is less active by several orders of magnitude as an FP receptor ligand when compared to 15(R)-cloprostenol. However,…

AFC is a synthetic substrate for the isoprenylated protein methyltransferase (also known as S-adenosylmethionine-dependent methyltransferase). Because it is able to serve as a substrate for the methyltransferase, it effectively functions as an inhibitor of methylation of endogenous isoprenylated proteins.

A β-adrenergic receptor agonist with potent positive inotropic effects in vivo; strongest effects on β1 receptors, with lesser but significant β2 receptor activation and only weak α1 receptor actions; strongly increases cardiac contractility.

A pan-caspase inhibitor that blocks apoptosis, prevents the production of cytokines, and inhibits T cell proliferation dose-dependently at 1-100 μM.
