(S)-Terazosin is an active S-enantiomer of Terazosin. (S)-Terazosin is a potent and high-affinity antagonist of α-adrenoceptor(α1a, α1b and α1d-adrenoceptor with Ki values of 3.91 nM, 0.79 nM and 1.16 nM, respectively).
Iloperidone metabolite P95 is a metabolite of the atypical antipsychotic iloperidone . It binds to the serotonin (5-HT) receptor subtype 5-HT2A and α1-, α2B-, and α2C-adrenergic receptors with mean Ki values of 7.08, 21.38, 83.18, and 47.86 nM, respectively, but does not cross the blood-brain barrier.
