A series of N-(4-amino-2-butynyl)acetamides were synthesized and examined for their inhibitory activity on detrusor contraction and mydriatic activity as an index of anticholinergic side effect. Among those compounds synthesized, (+)-2-cyclohexyl-N-(4-dimethylamino-2-butynyl)-2-hydroxy-2-phenylacetamide hydrochloride ((+)-13b·HCl), 2-cyclohexyl-2-hydroxy-N-(4-methylamino-2-butynyl)-2-phenylacetamide hydrochloride (13c·HCl), N-(4-dimethylamino-2-butynyl)-2, 2-diphenyl-2-hydroxyacetamide hydrochloride (14a·HCl), and 2, 2-diphenyl-N-(4-ethylamino-2-butynyl)-2-hydroxyacetamide hydrochloride (14b·HCl) showed equipotent inhibitory activity on detrusor contraction to oxybutynin (1) and less mydriatic activity. Further evaluation of these compounds as an agent for the treatment of overactive detrusor has been examined.
合成了一系列N-(4-氨基-2-丁炔基)乙酰酰胺,并检测了其对逼尿肌收缩的抑制活性以及作为抗胆碱能副作用指标的散瞳活性。在合成的化合物中,(+)-2-环己基-N-(4-二甲氨基-2-丁炔基)-2-羟基-2-苯基乙酰酰胺盐酸盐((+)-13b·HCl)、2-环己基-2-羟基-N-(4-甲氨基-2-丁炔基)-2-苯基乙酰酰胺盐酸盐(13c·HCl)、N-(4-二甲氨基-2-丁炔基)-2,2-二苯基-2-羟基乙酰酰胺盐酸盐(14a·HCl)和2,2-二苯基-N-(4-乙氨基-2-丁炔基)-2-羟基乙酰酰胺盐酸盐(14b·HCl)在抑制逼尿肌收缩方面表现出与氧丁嗪(1)相当的活性,并且散瞳活性较低。进一步评估这些化合物作为治疗膀胱过度活动的药物的潜力。
