Orvepitant maleate is an effective, selective, and well-tolerated neurokinin-1 receptor (NK-1) antagonist (pKi: 10.2 for human neurokinin-1 receptor). Orvepitant maleate has the potential for depressive disorder and chronic refractory cough (CRC) treatmen
YM49598 is a tachykinin receptor antagonist. YM49598 exhibited high binding affinities at NK(1) (pK(i) = 9.09 + - 0.02) and NK(2) (pK(i) = 9.94 + - 0.03) receptors, respectively. YM49598 was almost inactive but produced a potent inhibition (IC(50) = 11 +
