Product Introduction
Bioactivity


英文名: RG-12525

描述: RG-12525（NID 525） 是一种可口服且具有选择性和竞争性的白三烯 D （LTD）拮抗剂，对 LTC4，LTD4 和 LTE4 诱导的豚鼠薄壁带收缩有抑制作用，IC50 值分别为 2.6 nM，2.5 nM 和 7 nM。RG-12525 对 CYP3A4 有抑制作用， Ki 值为 0.5 µM。RG-12525 是一种新型高效的 PPAR-γ 激动剂（IC50 值约为 60 nM），具有物种特异性，可用于研究哮喘。

体外活性: RG-12525 competitively inhibits 3H-LTD4 binding to lung membranes (Ki = 3.0 +/- 0.3 nM) and antagonizes the spasmogenic activity of LTC4, LTD4, and LTE4 on lung strips in a competitive manner (KB values = 3 nM), displaying greater than 8000-fold selectivity[1]. RG-12525 (2.5 µM or 25 µM) inhibits the microsomal activity of CYP2C9 and -3A4 but does not significantly inhibit CYP1A2, -2A6, -2C19, or -2D6. Additionally, at 25 µM concentration, RG-12525 causes substantial inhibition at the 5 and 10 µM midazolam concentrations[3].

体内活性: Orally, RG-12525 inhibits LTD4-induced wheal formation with an ED50 of 5 mg/kg and a half-life (t1/2) of 10 hours at 9 mg/kg. It also inhibits LTD4-induced bronchoconstriction with an ED50 of 0.6 mg/kg and anaphylactic death with an ED50 of 2.2 mg/kg and a half-life (t1/2) of 7 hours at 10 mg/kg. Additionally, RG-12525 inhibits antigen-induced bronchoconstriction with an ED50 of 0.6 mg/kg[1]. In the systemic anaphylaxis model, RG-12525 inhibits antigen-induced mortality with an ED50 (95% confidence interval) of 2.2 (0.8-6.4) mg/kg. Furthermore, RG-12525 protects against LTD4-induced bronchoconstriction in a model measuring changes in pulmonary function, with an ED50 of 0.6 (0.4-1.0) mg/kg[2].
