BMY 7378 dihydrochloride (BMY7378 HCl) , α1D-adrenergic receptor antagonist, is a weak partial agonist antagonist of 5-HT1A receptor.

α1 adrenoceptor-MO-1 (S enantiomer) has affinity at alpha 1 adrenergic receptor with alphalytic activity and analgesic action. It has more active than R enantiomer.

Arbutamine (GP 21213) is a novel potent non-selective beta-adrenoceptor agonist with alpha-1-sympathomimetic activity.Arbutamine promotes cardiac stress and increases heart rate, cardiac contractility.Arbutamine can be used to study cardiac stress and coronary artery disease

Bunazosin Hydrochloride (E 1015) is an alpha(1)-adrenoceptor antagonist used as a systemic antihypertensive and an ocular hypotensive drug.

Azepexole dihydrochloride (B-HT 933), a potent and selective alpha 2-adrenoceptor agonist, exhibits affinity for α2A-, α2B-, and α2C-adrenoceptor subtypes with pKis of 8.3, 7.6, and 7.5, respectively [1]. It elicits a concentration-dependent inhibition of peristaltic contractions, evidenced by an IC50 of 78.72 nM.

Dilevalol, the RR-stereoisomer of labetalol, is a non-cardioselective beta-adrenoceptor antagonist with substantial partial beta 2-agonist and negligible alpha 1-blocking activity.

Abanoquil is an antagonist of alpha-1 adrenoceptor.

SKF 89748 is an agonists of alpha 1-adrenoceptor.

Rec 15/2615 is an antagonist of α1B-adrenergic receptors (α1B-ARs; Ki = 0.45 nM for the recombinant human receptor).1 It selectively inhibits α1B-ARs over α1A-, α1D-, and α1L-ARs (Kis = 7.59, 10.23, and 49 nM, respectively). Rec 15/2615 inhibits norepinephrine-induced contractions of isolated rabbit prostate and urethral strips (Kis = 100 and 316.2 nM, respectively), as well as reduces norepinephrine-induced contractions of chloroethylclonidine-precontracted isolated rabbit aortic rings (Ki = 50 nM).2 It decreases diastolic blood pressure (ED25 = 183 μg/kg, i.v.) and increases intracavernous pressure in anesthetized dogs when administered intracavernously at doses ranging from 30 and 1,000 μg/kg.1,2 |1.

Beta-Yohimbine has approximately twice as toxic as yohimbine and corynanthine about one fifth as toxic. Beta-yohimbine has alpha-1 and alpha-2 adrenoceptor blocking activities, it has cardiovascular effects. Beta-Yohimbine has anti-plasmodial and anti-mal

l-Stephanine is a potent and highly selective alpha 1 adrenoceptor blocker, inhibits anococcygeus muscle contraction induced by phenylephrine with pA2 values of 6.76. Stephanine shows significant antiplasmodial activities with IC(50) ranged from 1.2 uM to 52.3 uM. Stephanine and crebanine have high inhibitory activity against gram-positive animal pathogenic bacteria, with MIC values of 0.078-0.312g l, but low inhibitory activity against gram-negative animal pathogenic bacteria, they also inhibit hyphal growth of the plant pathogens Cercospora kaki.
