Nebentan Chemical Properties, Uses, Production

Uses

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[1]. YM598 can ameliorate the progression of cor pulmonale and myocardial infarction in vivo[2].

in vivo

Nebentan (oral administration; 0.1-1 mg/kg; 4 weeks) significantly inhibits the progression of pulmonary hypertension and the development of right ventricular hypertrophy[2].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[2].

IC 50

ETA: 0.697 nM (Ki); ETB: 569 nM (Ki)
