Disease relevance of Ono-NT-126

The results indicate that ONO NT-126 is a potent and selective antagonist of TXA2 receptors in human astrocytoma cells [1].
BACKGROUND/AIMS: We evaluated the effects of an antagonist of the thromboxane A2 receptor (ONO-NT-126) in an animal model of inflammatory bowel disease (IBD) [2].

High impact information on Ono-NT-126

In this study, we developed a guinea pig model for propranolol-induced bronchoconstriction (PIB) after antigen inhalation and investigated the effect of specific thromboxane (TXA2) receptor antagonists, S-1452 and ONO NT-126, on PIB in passively sensitized and artificially ventilated guinea pigs to determine whether TXA2 is involved in PIB [3].
2. The effects of inhaled IL-8 on bronchial responsiveness and of the TXA2 antagonists, S-1452 (0.01 and 0.1 mg kg-1) and ONO-NT-126 (1.0 or 10 micrograms kg-1), on IL-8-induced BHR were examined by use of a modified Konzett-Rössler method in guinea-pigs [4].
Treatment with specific TXA2 antagonist, calcium 5(Z)-1R,2S,3S,4S-7-[3-phenylsulfonylaminobicyclo[2,2,1]hept-2-yl]- 5-heptonoate hydrate (S-1452) and 5(Z-6-[(1R,2R,3R,4S)-3-(N-4-bromobenzenesulfonyl aminomethyl) bicyclo[2,2,1]heptane-2-yl]-hex-5-enoic acid (ONO-NT-126), enhanced the cisplatin-induced apoptosis in each cell line [5].
[3H]SQ29548 binding to membranes was inhibited by ONO NT-126 and the other TXA2 antagonists with Ki values (nM) of 0.09, 2.18, 8.35 and 25.9 for ONO NT-126, S-145, SQ29548 and ONO3708, respectively [1].
