Prostaglandin E2 (PGE2) exerts its effects through four separate G coupled-protein receptors (EP1-4). L-161,982 is a potent and selective EP4 receptor antagonist. It demonstrates selective binding to human EP4 receptors with a Ki value of 0.024 µM compared to other receptors of the prostanoid family, EP1, EP2, EP3,...

SC-51089 is an antagonist of the prostaglandin E2 (PGE2) receptor subtype EP1 (Ki = 1.332 µM). It is selective for EP1 over EP2, EP3, and EP4 (Kis = >100, 17.5, and >100 µM, respectively), as well as the PGD2 receptor DP, PGF2alpha receptor FP, PGI2 receptor IP, and thromboxane A2 receptor TP (Kis = >100, 61.13,...

Casein Kinase 2 (CK2) is a constitutive protein kinase involved in many signal transduction pathways. CK2 is known to negatively regulate apoptosis, and its activity is increased in many proliferating tissues and tumors, which lends promise as an anticancer drug target. CAY10578 is a potent inhibitor of CK2 with an...

S-Nitrosothiols (RSNOs) are a class of molecules that function as exogenous and endogenous nitric oxide (NO) donors. RSNOs found in vivo include proteins such as S-nitrosohemoglobin and S-nitrosoalbumin, as well as low molecular weight species such as S-nitrosoglutathione (GSNO) and S-nitrosocysteine (CysNO)....
