The new aryloxy acetic acid amide derivatives of formula (I) where R1 and R2 are the same or different and can be hydrogen atom or C1-4 alkanoylamido group optionally substituted by halogen atom or C1-4 alkyl-sulfonylamido group or N'-( C1-4 alkyl)-ureido group C1-6 alkoxy-carbonyl-amido or di-( C1-4 alkyl)-amino group with the proviso that only one of them can be hydrogen atom, or R1 and R2 form together a -NH-CO-NH-, -NH-N=CH- or -NH-CO-O- chain attached to two neighbouring carbon atoms of the benzyl group, R3 and R4 mean the same or different C1-4 alkyl groups which are substituted by phenyl group, or R3 and R4 mean together a C4-6 alkylene chain which can be interrupted optionally by a nitrogen atom and which can contain a C-C double bound and which C4-6 alkylene chain can substituted by one or two substituents from the following hydroxy group, phenyl or phenoxy group optionally substituted by a C1-4 alkyl or trifluoro methyl group, =CH-phenyl group which can be substituted by halogen atom or C1-4 alkyl group, C1-4 alkyl group optionally substituted by hydroxy groµp and one or two phenyl groups which can be substituted by halogen atom or C1-4 alkyl group, C1-4 alkyl amino group which is substituted by a phenyl or naphtyl group which can be substituted optionally by a halogen atom or a C1-4 alkyl group, as well as their salts formed with organic or inorganic acids or bases and solvates of these compounds are functional antagonists of NMDA receptors, which target the NMDA receptors primarily via binding to the ifenprodil binding site. Furthermore objects of the present invention are the pharmaceutical compositions containing new aryloxy acetic acid amide derivatives of formula (I) or optical antipodes or racemates or the salts thereof as active ingredients and processes for producing these compounds and pharmaceutical compositions.
公式(I)的新的芳氧乙酸酰胺衍生物,其中R1和R2相同或不同,可以是氢原子或C1-4烷酰胺基团,可选择地被卤素原子或C1-4烷基磺酰胺基团或N'-(C1-4烷基)-脲基团C1-6烷氧基羰基胺或二-(C1-4烷基)-氨基团取代,但其中只有一个可以是氢原子,或者R1和R2共同形成一个-NH-CO-NH-,-NH-N=CH-或-NH-CO-O-链,附加在苯甲基的两个相邻碳原子上,R3和R4表示相同或不同的C1-4烷基,它们被苯基取代,或者R3和R4共同表示一个C4-6烷基链,可以被氮原子随意中断,并且可以包含一个C-C双键,这个C4-6烷基链可以被以下羟基,苯基或苯氧基取代,可选择地被C1-4烷基或三氟甲基基团取代,=CH-苯基团,可被卤素原子或C1-4烷基团取代,可选择地被羟基团取代的C1-4烷基基团以及一个或两个苯基团,这些苯基团可以被卤素原子或C1-4烷基团取代,被苯基或萘基团取代的C1-4烷基氨基团,这些基团可选择地被卤素原子或C1-4烷基团取代,以及它们与有机或无机酸或碱形成的盐和这些化合物的溶剂化合物,是NMDA受体的功能性拮抗剂,其通过主要结合ifenprodil结合位点来靶向NMDA受体。此外,本发明的目标是含有公式(I)的新的芳氧乙酸酰胺衍生物或其光学异构体或外消旋体或其盐作为活性成分的制药组合物以及制备这些化合物和制药组合物的过程。
