(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.
Ecopipam (SCH 39166) hydrochloride is a highly potent, selective, and orally active antagonist of dopamine D1 D5 receptors. It exhibits impressive binding affinities, with Ki values of 1.2 nM and 2.0 nM for D1 and D5 receptors, respectively. Ecopipam hydrochloride demonstrates remarkable selectivity, displaying over 40-fold selectivity compared to D2, D4, 5-HT, and α2a receptors, with Ki values of 0.98 μM, 5.52 μM, 0.08 μM, and 0.73 μM, respectively. Its application extends to various areas of research, including schizophrenia, cocaine addiction, and obesity [1] [3].
