S2449 Forskolin (Colforsin) Forskolin (Colforsin) is a ubiquitous activator of eukaryotic adenylyl cyclase (AC) in a wide variety of cell types, commonly used to raise levels of cAMP in the study and research of cell physiology. Forskolin also activates PXR and FXR activity. Forskolin stimulates autophagy.

S0837 HJC0197 HJC0197 is a selective Epac 1/2 dual antagonists with an IC50 of 5.9 μM for Epac2.
S6850 NE 52-QQ57 NE 52-QQ57 is a selective, and orally available antagonist of G-protein coupled receptor 4 (GPR4) with IC50 of 0.07 μM. NE 52-QQ57 effectively blocks GPR4-mediated cAMP accumulation with IC50 of 26.8 nM in HEK293 cells. The antagonism of GPR4 with NE 52-QQ57 significantly inhibits the AGE-induced increased expression of several key inflammatory cytokines and signaling molecules, including tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6, inducible nitric oxide synthase (iNOS), nitric oxide (NO), cyclooxygenase 2 (COX2), and prostaglandin E2 (PGE2).
