Naftopidil 2HCl is a selective 5-HT1A and α1-adrenergic receptor antagonist with IC50 of 0.1 μM and 0.2 μM, respectively. -
α-adrenergic (AR) antagonist/CaM inhibitor
Phenoxybenzamine is a cell-permeable, non-specific, irreversible α-adrenergic (AR) antagonist that also acts as an CaM inhibitor. -
α1-adrenoceptor antagonist
Silodosin(Rapaflo) is an α1-adrenoceptor antagonist with high uroselectivity. It causes practically no orthostatic hypotension (in contrast to other α1 blockers). -
alpha-1A/alpha-1B-adrenoceptor antagonist
Tamsulosin is an alpha1a-selective alpha blocker used in the symptomatic treatment of benign prostatic hyperplasia (BPH). -
β2 adrenergic antagonist
ICI 118551 hydrochloride is a selective β2 adrenergic antagonist. -
Adrenoceptors antagonist
BRL 44408 maleate is a high purity Adrenoceptors antagonist. It increases hippocampal noradrenalin release following systemic administration. -
Adrenergic α1 Receptor Antagonist
HEAT hydrochloride is a very selective α1-AR adrenoceptor antagonist, precursor of the 3-[125I]-derivative. Adrenoreceptors (AR) or adrenergic receptors are G-protein coupled receptors involved in a variety of sympathetic nervous system processes. -
5-HT1A receptor antagonist
NAN-190 is a drug and research chemical widely used in scientific studies. It was previously believed to act as a selective 5-HT1A receptor antagonist, but a subsequent discovery showed that it also potently blocks the α2-adrenergic receptor. -
α2-adrenergic receptor antagonist
Rauwolscine is a natural alkaloid that acts as a selective and reversible α2-adrenergic receptor antagonist (Ki = 12 nM). -
Adrenoceptors antagonist

Adrenoceptors antagonist
(S)-Timolol maleate is a adrenergic receptor antagonist selective for β1-AR. -
adrenergic receptor antagonist
Celiprolol HCl is a b1 adrenergic receptor antagonist and a b2 adrenergic receptor partial agonist that has been shown to relax human arteries and veins with ED50 values of 40-50 M in vitro. -
α2 adrenergic receptor antagonist
Atipamezole HCl is a selective α2-adrenergic receptor antagonist (Ki values are 1.1, 1.0, 0.89, 1300 and 6500 nM for α2A, α2B, α2C, α1A and α1B receptors respectively). Has been shown to be a brain penetrant. -

α1A antagonist
RS 17053 HCl is α1A-adrenoceptor antagonist, with very high affinity for α1A receptors (pKi and pA2 estimates of 9.1 - 9.9) and a 30 - 100 fold selectivity over the α1B and α1D subtypes (pKi and pA2 estimates 7.7 - 7.8). -
beta-adrenergic receptor antagonist
Nifenalol, also known as INPEA, is a new beta-adrenergic receptor antagonist. -
β-adrenergic receptor antagonist
(R)-Atenolol is a beta blocker used to treat high blood pressure and chest pain (angina). It can also reduce the risk of death after a heart attack. -
α1A-adrenoceptor antagonist
Nicergoline is an ergot derivative used to treat senile dementia and other disorders with vascular origins. It has been found to increase mental agility and enhance clarity and perception. It decreases vascular resistance and increases arterial blood flow in the brain, improving the utilization of oxygen and glucose by brain cells. It has similar vasoactive properties in other areas of the body, particularly the lungs. Nicergoline is used for vascular disorders such as cerebral thrombosis and atherosclerosis, arterial blockages in the limbs, Raynaud's disease, vascular migraines, and retinopathy. -
