least 1000-fold more potent as an antagonist of A1 than of A2adenosine receptors. While most substitutions on the 8-cycloalkyl moiety caused decreased potency to inhibit both A1 and A2adenosine receptors, 8-[trans-4-(acetamidomethyl)cyclohexyl]-1,3-dipropylxanthine was nearly equipotent as an antagonist of the two receptors and appeared to be the most potentantagonist of A2adenosine receptors reported
Preventives/remedies for voiding disturbance containing a compound having both of an acetylcholinesterase inhibitory action and an α1 antagonistic action which exhibits an excellent effect of improving the urinary function of the bladder (i.e., effects of improving urine flow rate and voiding efficiency) without affecting the urinary pressure or the blood pressure.
