| Catalog No.GC33780 |
RG-12525 (NID 525) es un antagonista especÍfico, competitivo y eficaz por vÍa oral de los peptidoleucotrienos, LTC4, LTD4 y LTE4, que inhibe las contracciones de las tiras parenquimatosas del conejillo de indias inducidas por LTC4, LTD4 y LTE4, con IC50 de 2,6 nM, 2,5 nM y 7 nM, respectivamente; RG-12525 (NID 525) también es un agonista del receptor gamma activado por el proliferador de peroxisomas (PPAR-gamma) con IC50 de aproximadamente 60 nM y un potente inhibidor de CYP3A4, con un valor de Ki de 0,5 μM.

RG-12525 is a a specific, competitive and orally effective antagonist of the peptidoleukotrienes, LTC4, LTD4 and LTE4, inhibiting LTC4-, LTD4- and LTE4-inducd guinea pig parenchymal strips contractions, with IC50s of 2.6 nM, 2.5 nM and 7 nM, respectively; RG-12525 is also a peroxisome proliferator-activated receptor gamma (PPAR-gamma) agonist with IC50 of appr 60 nM and a potent inhibitor of CYP3A4, with a Ki value of 0.5 µM.
RG 12525 competitively inhibits 3H-LTD4 binding to lung membranes (Ki = 3.0 +/- 0.3 nM) and competitively antagonizes the spasmogenic activity of LTC4, LTD4 and LTE4 on lung strips (KB values = 3 nM) with 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. RG 12525 (25 µM) also causes a substantial amount of inhibition at the 5 and 10 µM midazolam concentrations[2].
RG 12525 orally inhibits LTD4 induced wheal formation (ED50 = 5 mg/kg with a t1/2 = 10 hrs at 9 mg/kg), LTD4 induces bronchoconstriction (ED50 = 0.6 mg/kg), and anaphylactic death (ED50 = 2.2 mg/kg with a t1/2 = 7 hrs at 10 mg/kg) and antigen induces bronchoconstriction (ED50 = 0.6 mg/kg)[1]. RG 12525 inhibits antigen-induced mortality in the systemic anaphylaxis model with an ED50 (95% confidence interval) = 2.2 (0.8-6.4) mg/kg. RG 12525 also protects against LTD4-induced bronchoconstriction in a model measuring changes in pulmonary function with an ED50 = 0.6 (0.4-1.0) mg/kg[3].
