A series of 2-(2-aminoethoxy)-1-phenylethanols having a variety of N- and phenyl-substitution patterns as well as 5- and 6-membered heteroaryl counterparts of our prototype compound 1 (2-(2-dimethylaminoethoxy)-1-phenylethanol) have been prepared and evaluated for antiamnestic and antihypoxic activities. Compound 3b, the 3-methylphenyl analogue of 1, proved to be significantly more potent than 1 in reversing eelctroconvulsive shock-induced amnesia as well as CO2-induced learning-impairment in mice. It exhibited low acute toxicity in mice and afforded a greater brain/serum concentration ratio than 1 after oral administration to rats.
一系列具有多种N-和苯基取代模式的2-(2-氨基乙氧基)-1-苯乙醇及其5-和6元异芳烃对应化合物已经被合成并评估了其抗遗忘和抗缺氧活性。化合物3b,即1的3-甲基苯基类似物,在逆转电休克引起的健忘症及CO2诱导的小鼠学习障碍方面的效力显著高于1。它在小鼠中表现出低急性毒性,并且在口服给药后比1在大鼠中提供了更高的脑/血清浓度比。
