The invention relates to novel substances, and more particularly to optical isomers of (+) and (−)-benzhydryl ureas of formula (I) and (+) and (−)-1-[(3-chlorophenyl)-phenyl-methyl]urea, a pharmaceutical composition based thereon, and a method for producing said optical isomers and for using same on the basis of the different therapeutic activity exhibited. (I) Where R≠R′ and are selected from the group comprising hydrogen, alkyl, halogen, nitro, amino, alkylamino and hydroxy groups and are situated in the ortho-, para- or meta-positions of the benzene rings. When racemic Halodif 1-[(3-chlorophenyl)-phenyl-methyl]urea was separated using the method according to the invention, optical isomers of (+) and (−)-1-[(3-chlorophenyl)-phenyl-methyl]urea (Halodif isomers) with different degrees of therapeutic activity were produced.
该发明涉及新颖物质,更具体地涉及公式(I)中的光学异构体以及基于此的药物组合物和生产该光学异构体的方法,以及基于展示的不同治疗活性使用它们的方法。其中R≠R′,并且选自包括氢、烷基、卤素、硝基、氨基、烷基氨基和羟基的基团,并位于苯环的邻位、对位或间位。当使用该发明的方法分离混合的1-[(3-氯苯基)-苯基甲基]脲的外消旋体时,产生了具有不同治疗活性程度的光学异构体(Halodif异构体)。
