RS 17053 is an ?1A-adrenergic receptor (?1A-AR) antagonist.{18268} It selectively binds to the ?1A-AR (Ki = 2.5 nM) over ?1B- and ?1D-ARs (Kis = 50 and 79 nM, respectively). RS 17053 inhibits norepinephrine-induced contractions in isolated rat kidney and mesenteric arteries (pA2s = 9.8 and 9.9, respectively), tissues that endogenously express high levels of ?1A-AR, and, to a lesser extent, in isolated rat aortic rings, which highly express ?1D-ARs, and human lower urinary tract tissue (pA2s = 7.7 and 7.3, respectively).{62039} It also inhibits phenylephrine-induced increases in mean arterial pressure (MAP) in normotensive and spontaneously hypertensive rats (ED50s = 528 and 533 µg/kg, respectively).{62040}
