This invention is directed toward pharmacologically active compounds of the formula ##STR1## wherein A represents a nitrogen atom which may be substituted by a methyl, cyclopropylmethyl, di(C.sub.1-4 alkyl)aminoethyl, methoxymethyl or hydroxyethyl group and B represents a carbonyl group or A and B together represent a grouping of the formula ##STR2## in which R.sup.a represents a hydrogen atom or a lower alkyl or hydroxymethyl group and X represents a nitrogen atom or C--R.sup.b wherein R.sup.b represents a hydrogen atom or a lower alkyl or hydroxymethyl group; R represents a halogen atom or a nitro or trifluoromethyl group; R.sup.1 represents a hydrogen atom or a lower alkyl group; R.sup.2 represents an acyl group derived from a naturally occurring amino acid (all such groups which contain an asymmetric carbon atom having the L- or D,L-configuration) and R.sup.3 represents a phenyl, halophenyl or 2-pyridyl group And acid addition salts thereof. Also provided are methods for their preparation and intermediates thereof. These compounds exhibit activity as anticonvulsants, muscle relaxants and sedatives.
这项发明涉及公式为##STR1##的药理活性化合物,其中A代表氮原子,可被甲基、环丙甲基、二(C.sub.1-4烷基)氨基乙基、甲氧甲基或羟乙基基团取代,B代表羰基基团或A和B一起代表公式##STR2##的基团,其中R.sup.a代表氢原子或较低的烷基或羟甲基基团,X代表氮原子或C--R.sup.b,其中R.sup.b代表氢原子或较低的烷基或羟甲基基团;R代表卤原子或硝基或三氟甲基基团;R.sup.1代表氢原子或较低的烷基基团;R.sup.2代表从天然氨基酸衍生的酰基基团(所有这些基团都包含具有L-或D,L-构型的不对称碳原子)和R.sup.3代表苯基、卤代苯基或2-吡啶基团,以及它们的酸加成盐。还提供了它们的制备方法和中间体。这些化合物表现出抗惊厥、肌肉松弛和镇静活性。
