HPGDS inhibitor 1 是口服具有活性的HPGDS选择性抑制剂，在酶和细胞分析中的IC50值分别为 0.6 nM 和 32 nM，但对 L-PGDS、mPGES、COX-1、COX-2 、5-LOX无抑制作用。

HPGDS inhibitor 1 is a novel and selective inhibitor for Hematopoietic Prostaglandin D Synthase (HPGDS) with an IC50 Value of 0.7 nM.

Kinetic characterization of Abl inhibition: The ATP/NADH-coupled assay system in a 96-well format is used to determine the initial velocity of Abl tyrosine kinase catalyzed peptide phosphorylation. The reaction mixture contained 20 mM Tris-HCl, (pH 8.0), 50 mM NaCl, 10 mM MgCl2, 2 mM PEP [2-(Phosphonooxy)- 2-propenoic acid) and 20 μg Abl peptide substrate (EAIYAAPFAKKK), fixed or varied (to determine inhibitor kinetic parameters) concentration of inhibitor applied, 1/50 of the final reaction mixture volume of PK/LDH enzyme (pyruvate kinase/lactic dehydrogenase enzymes from rabbit muscle), 160 μM NADH, 0.16 μM Abl, and ATP added last to start the reaction. Absorbance data are collected every 20s at 340 nm using a SpectraMax M5 Microplate Reader.
