E7046 (ER-886406)

E7046 (ER-886406) is a selective inhibitor of the prostaglandin E2 (PGE2) receptor EP4 with IC50 of 13.5 nM and Ki of 23.14 nM.

S0141

NQ301

NQ301 (Compound 211), an antiplatelet and antithrombotic agent, is a selective CD45 inhibitor with IC50 of 200 nM. NQ301 inhibits thromboxane A2 receptor (TXA2) and synthase activity in rabbit platelets.

S0495

BI-671800

BI-671800 (AP-761, Cmpd A) is a highly specific and potent antagonist of chemoattractant receptor-homologous molecule on Th2 cells (DP2/CRTH2) with IC50 of 4.5 nM and 3.7 nM for PGD2 binding to human CRTH2 and murine CRTH2, respectively. BI-671800 is associated with a small improvement in FEV1 in symptomatic controller-naïve asthma patients, and in patients on ICS.

S0305

RO1138452

RO1138452 (CAY10441) is a potent and selective antagonist of IP (prostacyclin, PGI2) receptor with pKi of 9.3 and 8.7 in human platelets and a recombinant IP receptor system, respectively.

S6793

TG4-155

TG4-155 is a potent and selective Prostaglandin Receptor EP2(PTGER2) antagonist with Ki value of 9.9 nM.

S0010

Ralinepag

Ralinepag (APD811) is a potent, orally bioavailable and non-prostanoid prostacyclin (IP) receptor agonist with EC50 of 8.5 nM, 530 nM and 850 nM for human IP receptor, rat IP receptor and human DP1 receptor, respectively.

S0325

Treprostinil sodium

Treprostinil sodium (UT-15, Remodulin, Orenitram, Tyvaso, Trevyent) is a potent agonist of DP1, EP2 and IP receptors with Ki 4.4 nM, 3.6 nM and 32 nM, respectively.

S0541

Dazoxiben hydrochloride

Dazoxiben hydrochloride (HCl) is a potent, selevtive and orally active inhibitor of thromboxane (TX) synthase. Dazoxiben inhibits TXB2 production in clotting human whole blood with IC50 of 0.3 μM and causes parallel enhancement of PGE2 production.

S3346New

1-Methylnicotinamide chloride

1-Methylnicotinamide (1-MNA, 3-Carbamoyl-1-methylpyridin-1-ium, Trigonellamide) chloride is an active endogenous metabolite of nicotinamide that exhibits anti-inflammatory and anti-thrombotic activities. 1-Methylnicotinamide enhances tumor vasculature formation and markedly increases prostacyclin (PGI2) generation.
