15(R)-PGE1 is the "unnatural" C-15 stereoisomer of PGE1. It is essentially inactive biologically when compared to PGE1. It is a non-competitive inhibitor of 15-hydroxy PGDH with an IC50 of 189 µM.Formal Name: 9-oxo-11alpha,15R-dihydroxy-prost-13E-en-1-oic acid. CAS Number: 20897-91-0. Synonyms: 15(R)-PGE1, 15-epi...

ST638 is a tyrosine kinase inhibitor (IC50 = 370 nM). It suppresses tyrosine phosphorylation induced by tumor necrosis factor-alpha and phorbol myristate acetate in neutrophils and by angiotensin II in cardiac fibroblasts.Formal Name: 2-cyano-3-[3-ethoxy-4-hydroxy-5-[(5-phenylthio)methyl]phenyl]-2-propenamide. CAS...

Butaprost is an EP2 selective agonist which has frequently been used to pharmacologically define the EP receptor expression profile of various human and animal tissues and cells. Prostaglandin free acids generally bind to their cognate receptors with 10 to 100 times the affinity of the corresponding ester...

Butaprost is a structural analog of prostaglandin E2 (PGE2) with good selectivity for the EP2 receptor subtype. Butaprost has frequently been used to pharmacologically define the EP receptor expression profile of various human and animal tissues and cells. Serious confusion as to the structure of butaprost was...
