A series of 5-amino-3-phenylisoxazole derivatives was synthesized and evaluated as part of a search for new types of centrally acting muscle relaxants. The derivtives with an alkylaminopropyl moiety exhibited muscle relaxant activity comparable to that of tolperisone (1), but this activity was accompanied by strong general central nervous system (CNS) depressant and slight anticonvulsant activities.On the other hand, the derivative with a propanamide moiety exhibited a favorable pharmacological profile for a selective muscle relaxant with little CNS depressant action.
作为寻找新型中枢性肌肉松弛剂的一部分,合成并评估了一系列 5-氨基-3-苯基异恶唑衍生物。具有烷基氨基丙基部分的衍生物表现出与甲苯哌丙酮 (1) 相当的肌肉松弛活性,但这种活性伴随着强烈的一般中枢神经系统 (CNS) 抑制剂和轻微的抗惊厥活性。 另一方面,具有丙酰胺部分的衍生物作为一种选择性肌肉松弛剂,表现出良好的药理学特征,几乎没有中枢神经系统抑制作用。
