H-PGDS Inhibitor I is a Prostaglandin D Synthase (hematopoietic-type) Inhibitor. MDK36122 has no code name, and has CAS#1033836-12-2. The last 5-digit was used for name for easy communication. MDK36122 selectively blocks HPGDS (IC50s = 0.7 and 32 nM in enzyme and cellular assays, respectively) with little activity against the related human enzymes L-PGDS, mPGES, COX-1, COX-2, and 5-LOX.

HPGDS inhibitor 1 has equal potency against purified HPGDS from human, rat, dog, and sheep (IC50, 0.5-2.3 nM).
HPGDS inhibitor 1 (compound 8; 1 mg/kg) has excellent PK characteristics with 76% bioavailability, and the T1/2 is 4.1 hours in rats.
Rats dosed orally with 1 mg/kg and 10 mg/kg HPGDS inhibitor 1 (compound 8) are sacrificed at various times. Oral administration of HPGDS inhibitor 1 blocks PGD2 production in the rat spleen; inhibition of PGD2 is inversely correlated with the plasma concentration of HPGDS inhibitor 1 in a time- and dose-dependent manner.
HPGDS inhibitor 1 (compound 8; 1 mg/mL) illustrates efficacy in an in vivo sheep model of asthma.
