With the aim of improving of the efficacy and decreasing the side effects of oxybutynin (1), N-[(tetrahydro-3- or 4-pyridyl)methyl]-, N-(4-piperidyl)-, and N-(3- or 4-piperidylalkyl)-2-hydroxyacetamides (3a-n, 4a-g) and the related carboxamides (3o-r, 4h-k, 13', 17) were synthesized and evaluated for inhibitory activity against urinary bladder rhythmic contraction in rats and for mydriatic activity
为了提高功效并减少奥昔布宁(1)的副作用,N-[(四氢-3-或4-吡啶基)甲基]-,N-(4-哌啶基)-和N-(3合成了-或4-哌啶基烷基)-2-羟基乙酰胺(3a-n,4a-g)和相关的羧酰胺(3o-r,4h-k,13',17)并评估了其对膀胱节律性收缩的抑制活性大鼠和散瞳活动的大鼠。这些化合物中的一些在对膀胱收缩的抑制活性和对膀胱收缩的抑制活性与散瞳活性之间的选择性方面均优于奥昔布宁。其中,N-[((1,2,3,6-四氢-4-吡啶基)甲基]-和N-[(1,2,3,6-四氢-1-甲基-4-吡啶基)甲基]- 2-羟基-2,2-二苯基乙酰胺(3e,3f)对膀胱收缩表现出最有效的抑制活性(ED30 = 0。静脉注射分别为005和0.003 mg / kg)。从3e对豚鼠体外逼尿肌收缩的影响来看,似乎3e体内抑制膀胱收缩的活性主要与卡巴胆碱诱导的体外对逼尿肌收缩的抑制活性有关(类抗毒蕈碱活性)。
