AT-56

产品介绍 AT-56 是一种有效,选择性和具有口服活性的脂钙蛋白型前列腺素 D 合酶 (L-PGDS) 的抑制剂,IC50 值为 95 μM,Ki 值为 75 μM。AT-56 可选择性抑制 L-PGDS 催化的 PGD2 介导的嗜睡或疼痛反应。
生物活性

AT-56 is a potent, selective and orally active inhibitor of lipocalin-type prostaglandin D synthase (L-PGDS), with an IC50 of 95 μM and Ki of 75 μM. AT-56 could selectively suppress the drowsiness or pain reaction mediated by L-PGDS-catalyzed PGD2.

体外研究

AT-56 (1-30 μM; 10 minutes) dose-dependently inhibits the production of PGD2 in L-PGDS-expressing human medulloblastoma TE-671 cells with an IC50 of about 3 μM.

西域 has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究

AT-56 ( 1-30 mg/kg; p.o.) suppresses the PGD2 production in the stab-wounded brain.
AT-56 (1-10 mg/kg; p.o.) suppresses the L-PGDS-mediated allergic airway inflammation in mice.
AT-56 (10 mg/kg; p.o.) exhibits Cmax (2.15 μg/ml), half-life (1.71 h) and high oral bioavailability (82%).

Animal Model: H-PGDS KO mice (14-16weeks, 25-30 g, C57BL/6 strain) with a stab wound brain injury
Dosage: 0, 1, 3, 10, 30 mg/kg
Administration: P.o. 1 h before the stab wound injury
Result: Inhibited the L-PGDS reaction in the brain.
Decreased the total amount of PGD2 in the brain to 40% with 30 mg/kg AT-56.
Animal Model: Human L-PGDS-overexpressing TG mice (males, 14-16 weeks, 25-30 g)
Dosage:  0, 1, 10 mg/kg
Administration: P.o. 1 h before and 24 h after the antigen exposure
Result: Prevented the eosinophil infiltration by inhibiting transgened human L-PGDS.
Animal Model: Male C57BL/6 mice (7 weeks, 22-26 g)
Dosage: 10 mg/kg for p.o. and 2 mg/kg for i.v. (Pharmacokinetic Analysis)
Administration: P.o. and i.v. administration
Result: Oral bioavailability (82%); Cmax (2.15 μg/ml); T1/2 (1.71 h, p.o.); T1/2 (2.35 h, i.v.).
