S 15535(1)在突触前和突触后5-HT(1A)受体上分别显示出激动剂和拮抗剂(弱部分激动剂)活性的独特特征。它已被证明在预测抗焦虑,抗抑郁和认知特性的几种模型中具有活性。为了提高其选择性和代谢稳定性,并以人类代谢研究的结果为指导,我们制备了一系列顺式和反式-2-(芳基环烷基胺)1-茚满醇。不论芳基环烷基胺部分的性质如何,或在茚满环上存在取代基,反式异构体始终显示出对人重组h5-HT(1A)受体的最高亲和力。其中,化合物39、42、45、49、52、53、54、57、61、64、67和70显示出与母体化合物1相似或更高的亲和力(pK(i)>或= 9.1)。5-HT(1A)配体经常遇到对α1-肾上腺素受体缺乏选择性的情况。尽管S 15535本身在这方面表现出合理的选择性(158倍),但反式哌嗪衍生物4-trans,35、39、41、47、64、68、69、70、71与alpha1-肾上腺

Compounds having the formula (I) wherein R and R.sub.1, similar or different, represent a hydrogen or halogen atom or a radical alkyl, alkoxy, amino, acylamino, phenylureido, --N.dbd.CH--N(R.sub.2)R.sub.3, nitro, imidazolyl, phenyl, SO.sub.3 H or cyano; R.sub.2 and R.sub.3 which may be similar or different, represent each an alkyl radical; the invention also relates to the salts of such compounds, their preparation, intermediates for preparing them and drugs containing them. ##STR1##
A novel series of readily water soluble 8-methylureido-4,5-dihydro-4-oxo-10H-imidazo[1,2-a]indeno[1,2-e]pyrazines were synthesized. The -10-yl acetic acid ((+)-3) and -10-carboxylidene (4) derivatives exhibit potent affinities (IC50 = 4 and 19 nM, respectively) and antagonist properties (IC50 = 2 and 3 nM, respectively) at the ionotropic AMPA receptor. These compounds also display anticonvulsant properties against both electrically and sound-induced convulsions in mice after ip, sc and iv administration with ED50 values between 0.9 and 11 mg/kg, thus suggesting adequate brain penetration.
