Prazosin 193-201 adrenoceptor alpha 1A Homo sapiens 155-166 25447534-0 2014 Molecular exploration of the alpha(1A)-adrenoceptor orthosteric site: binding site definition for epinephrine, HEAT and prazosin. Prazosin 120-128 adrenoceptor alpha 1A Homo sapiens 29-51 23935897-5 2013 Equilibrium and kinetic binding experiments were used to demonstrate that rho-Da1a, prazosin and HEAT compete at the alpha1A-adrenoceptor. Prazosin 84-92 adrenoceptor alpha 1A Homo sapiens 117-137 21262225-7 2011 In addition, using specific binding experiments, we established that these ions acted as negative allosteric ligands on prazosin/alpha(1A)-adrenoceptor interaction, but in a different manner from the allosteric modulator 5-(N-ethyl-N-isopropyl)-amiloride, suggesting distinct mode of interaction. Prazosin 120-128 adrenoceptor alpha 1A Homo sapiens 129-151 18379048-4 2008 On the other hand, the Gln167Phe mutant alpha 1a-AR showed reduced binding affinity for [3H]prazosin. Prazosin 88-100 adrenoceptor alpha 1A Homo sapiens 40-51 18379048-7 2008 The results provide direct evidence that these amino acid residues are responsible for the interactions between alpha 1a-AR and radioligand [3H]prazosin as well as tamsulosin and KMD-3213. Prazosin 140-152 adrenoceptor alpha 1A Homo sapiens 112-123 9249248-7 1997 For the alpha1A-adrenoceptor, binding studies revealed a pharmacological profile typical for the classically defined alpha1A-adrenoceptor, such that prazosin, RS-17053, WB 4101, 5-methylurapidil, Rec 15/2739 and S-niguldipine all displayed subnanomolar affinity. Prazosin 149-157 adrenoceptor alpha 1A Homo sapiens 8-28 11525314-5 2001 Prazosin, cyclazosin, RS-100329 and Ro70-0004/003 antagonized norepinephrine-induced contractile responses with affinity estimates (pK(B) or pA2) of 8.4, 7.3, 9.2 and 8.8, respectively, consistent with the singular involvement of alpha1A-adrenoceptor subtype. Prazosin 0-8 adrenoceptor alpha 1A Homo sapiens 230-250 10433504-11 1999 Schild analysis revealed that the affinity profile of this AR subtype to antagonists in the clone aH7 had a typical pattern for the alpha1a-AR; high affinity for prazosin and WB 4101, and low affinity for BMY7378 (pA2=9.5, 9.8 and 7.3, respectively). Prazosin 162-170 adrenoceptor alpha 1A Homo sapiens 59-61 9857099-8 1998 These findings prove that alpha1a adrenoceptor-subtype selective antagonists such as (-)-63 may be developed as uroselective agents for an improved treatment of BPH over nonselective alpha1 antagonists such as prazosin and terazosin, with fewer side effects. Prazosin 210-218 adrenoceptor alpha 1A Homo sapiens 26-46 9249248-7 1997 For the alpha1A-adrenoceptor, binding studies revealed a pharmacological profile typical for the classically defined alpha1A-adrenoceptor, such that prazosin, RS-17053, WB 4101, 5-methylurapidil, Rec 15/2739 and S-niguldipine all displayed subnanomolar affinity. Prazosin 149-157 adrenoceptor alpha 1A Homo sapiens 117-137 31067439-3 2019 Evidence is presented that the postulated alpha1L-adrenoceptor is simply the native alpha1A-adrenoceptor at which prazosin has low potency. Prazosin 114-122 adrenoceptor alpha 1A Homo sapiens 84-104 30719698-2 2019 Prazosin has a lower affinity for the lower urinary tract alpha1A -adrenoceptor than alpha1A -adrenoceptors found in other parts of the body.
