(R)-Terazosin

Research use only, not for human use.

(R)-Terazosin is an active R-enantiomer of Terazosin. (R)-Terazosin is a potent antagonist of α1-adrenoceptor (α1a, α1b and α1d-adrenoceptor with Ki values of 6.51 nM, 1.01 nM and 1.97 nM, respectively).

(R)-Terazosin is a potent antagonist of α1-adrenoceptor (α1a, α1b and α1d-adrenoceptor with Ki values of 6.51 nM, 1.01 nM and 1.97 nM, respectively). (R)-Terazosin is low affinity for α2a, α2B and α2c-adrenoceptor(Ki of 3.85 μM, 0.33 μM and 0.37 μM, respectively). (R)-Terazosin may prove to be a useful probe in understanding the functional role of subtypes of adrenoceptors in various tissues.(R)-Terazosin shows antagonism of at rat atrial α2B receptor (pEC30 : 5.69). (R)-Terazosin shows antagonism of at rat vas deferens α1A and α2A receptor (pA2 of 7.5 and 5.31, respectively).(In Vitro):(R)-Terazosin is low affinity for α2a, α2B and α2c-adrenoceptor with Ki values of 3.85 μM, 0.33 μM and 0.37 μM, respectively.(R)-Terazosin may prove to be a useful probe in understanding the functional role of subtypes of adrenoceptors in various tissues. Because it is a weaker antagonist at α2B sites than its enantiomer, it may be possible to use (R)-Terazosin to differentiate between pharmacological effects mediated by subtypes of α2-adrenoceptors in animal studies.(In Vivo):(R)-Terazosin shows antagonism of at rat atrial α2B receptor with a pEC30 of 5.69. (R)-Terazosin shows antagonism of at rat vas deferens α1A and α2A receptor with pA2 values of 7.5 and 5.31, respectively.
