Timapiprant sodium OC000459 sodium

产品介绍 Timapiprant sodium (OC000459 sodium) 是一种高效选择性的口服型 D 前列腺素受体 2 (DP2,也称为 CRTH2) 拮抗剂。Timapiprant sodium (OC000459 sodium) 有效地置换来自人重组 DP2 (K i=13 nM),大鼠重组 DP2 ( K i=3 nM) 和人天然 DP2 ( K i=4 nM) 的 [3H] PGD2。 Timapiprant sodium (OC000459 sodium) 抑制肥大细胞激活 Th2 淋巴细胞和嗜酸性粒细胞。
生物活性

Timapiprant sodium (OC000459 sodium) is a potent, selective, and orally active D prostanoid receptor 2 (DP2, also known as CRTH2) antagonist. Timapiprant sodium (OC000459 sodium) potently displaces [3H] PGD2 from human recombinant DP2 (Ki=13 nM), rat recombinant DP2 (Ki=3 nM), and human native DP2 (Ki=4 nM). Timapiprant sodium (OC000459 sodium) inhibits mast cell activation of Th2 lymphocytes and eosinophils.

体外研究

Timapiprant sodium (OC000459 sodium) (0.0001 μM-10 μM; 5 hours) inhibits chemotaxis (IC50=0.028 μM) of human Th2 lymphocytes and cytokine production (IC50=0.019 μM) by human Th2 lymphocytes.
Timapiprant sodium (OC000459 sodium) (1 μM) inhibits the activation of Th2 cells and eosinophils in response to supernatants from IgE/anti-IgE-activated human mast cells.
Timapiprant sodium (OC000459 sodium) (1 nM-1000 nM; 16 hours) inhibits the anti-apoptotic effect of PGD2 on Th2 cells with an IC50 of 0.035 uM.
