生物活性 | Nebentan (YM598 free base) is a potent, selective and orally active non-peptide endothelin ETA receptor antagonist through the modification of Bosentan (HY-A0013). Nebentan inhibits [125I] endothelin-1 binding to cloned human endothelin ETA and ETB receptor, with Ki of 0.697 nM and 569 nM, respectively. YM598 can ameliorate the progression of cor pulmonale and myocardial infarction in vivo. | ||||||||||||||||
体外研究 |
Nebentan inhibits the specific binding of [125I] endothelin-1 to endothelin ETA and ETB receptors in a concentration dependent manner, Ki values are 0.697 nM and 1.53 nM for human and rat endothelin ETA receptors, respectively. In contrast, YM598 exhibits low affinities for human and rat endothelin ETB receptors, with Ki values of 569 nM and 155 nM,respectively.In measurement of intracellular Ca2+ concentration, Nebentan concentration-dependently inhibits the increase in [Ca2+]i induced by 10 nM endothelin-1 in both CHO cells and A10 cells, the IC50 values are 26.2 nM for CHO cells and 26.7 nM for A10 cells, respectively. 西域 has not independently confirmed the accuracy of these methods. They are for reference only. | ||||||||||||||||
体内研究 |
Nebentan (oral administration; 0.1-1 mg/kg; 4 weeks) significantly inhibits the progression of pulmonary hypertension and the development of right ventricular hypertrophy.Nebentan (oral administration; 1 mg/kg; 30 weeks) significantly ameliorates the poor survival rate of CHF rats, it markedly reduces the hypertrophy of both ventricles as well as pulmonary congestion. 西域 has not independently confirmed the accuracy of these methods. They are for reference only. | ||||||||||||||||
