HPGDS inhibitor 3

Catalog No. T61250 CAS 2255311-93-2

HPGDS inhibitor 3 is a powerful oral compound that selectively inhibits the hematopoietic prostaglandin D synthase (H-PGDS). With an IC50 value of 9.4 nM and EC50 of 42 nM, it demonstrates high potency in peripherally restricting H-PGDS. Moreover, HPGDS inhibitor 3 exhibits excellent selectivity with no associated central nervous system toxicity. This compound also possesses favorable pharmacokinetic properties in mouse, rat, and dog models. Additionally, HPGDS inhibitor 3 displays noteworthy anti-inflammatory activity [1].

Description

In vivo

HPGDS inhibitor 3 (compound 1y), administered orally (PO) and intravenously (IV), demonstrates lower IV clearance, a similar steady-state volume of distribution, and an extended terminal half-life, along with high oral bioavailability and minimal brain exposure in mice, rats, and dogs. At dosages ranging from 0.003 to 1 mg/kg (PO; single administration), it dose-dependently reduces PGD2 levels to baseline and inhibits LPS-induced increases of PGD2 in plasma and skeletal muscle. Furthermore, dosages of 1, 3, and 10 mg/kg (PO; once daily for 16 days) significantly improve and expedite the functional recovery of injured limb muscles, with the greatest efficacy observed at ≥10 mg/kg daily. Tolerance levels vary by species and dosage, with rats tolerating up to 30 mg/kg/day over 7 days and dogs up to 30 mg/kg/day over 4 days without adverse effects, though higher doses are not tolerated. Pharmacokinetic analysis reveals that, across species, HPGDS inhibitor 3 maintains a low brain-to-blood ratio, reaffirming its safety and efficacy profile for potential therapeutic applications.
