摘要

Structure-activity studies were performed on the α_(1A)-adrenoceptor (AR) selective agonist N-[5-(1H-imidazol-4-yl)-5,6,7,8-tetrahydro-1-naphthalenyl]methanesulfonamide (4). Compounds were evaluated for binding activity at the α_(1A), α_(1b), α_(1d), α_(2a), and α_(2B) subtypes. Functional activity in tissues containing the α_(1A) (rabbit urethra), α_(1B) (rat spleen), α_(1D) (rat aorta), and α_(2A) (rat prostatic vas deferens) was also evaluated. A dog in vivo model simultaneously measuring intraurethral pressure (IUP) and mean arterial pressure (MAP) was used to assess the uroselectivity of the compounds. Many of the compounds that were highly selective in vitro for the α_(1A)-AR subtype were also more uroselective in vivo for increasing IUP over MAP than the nonselective α_1-agonists phenylpropanolamine (PPA) (1) and ST-1059 (2, the active metabolite of midodrine), supporting the hypothesis that greater α_(1A) selectivity would reduce cardiovascular side effects. However, the data also support a prominent role of the α_(1A)-AR subtype in the control of MAP.
