A series of thirty N-(phenoxy)alkyl or N-2-[2-(phenoxy)ethoxy]ethyl}aminoalkanols has been designed, synthesized and evaluated for anticonvulsant activity in MES, 6 Hz test, and pilocarpine-induced status epilepticus. Among the title compounds, the most promising seems R-(−)-2N-2-[2-(2,6-dimethylphenoxy)ethoxy]ethyl}aminopropan-1-ol hydrochloride (22a) with proved absolute configuration with X-ray
已设计,合成并评估了三十种N-(苯氧基)烷基或N- 2- [2-(2-苯氧基)乙氧基]乙基}氨基链烷醇,并评估了其在MES中的抗惊厥活性,6 Hz测试和毛果芸香碱引起的癫痫持续状态。在标题化合物中,最有前途的似乎是R -(-)-2 N- 2- [2-(2-(2,6-二甲基苯氧基)乙氧基]乙基}氨基丙烷-1-醇盐酸盐(22a),具有X的绝对构型射线分析和对映体纯度。该化合物在ED 50 = 12.92 mg / kg bw及其rotodod TD 50的MES测试中有效 = 33.26 mg / kg bw活性剂量在神经源性疼痛模型(福尔马林测试)中也有效。在高通量分析中,在81个靶标中,观察到该化合物对σ受体和5-HT转运蛋白的最强亲和力,并且该化合物不与hERG结合。在哈维氏弧菌测试中,它也没有表现出诱变特性。此外,鼠肝微粒体测定和药代动力学特征(小鼠,静脉,口服,腹膜内)表明,肝
