Tbe invention relates to 3H-1,2,3-triazolo[4,5-d]pyrimidine derivatives, especially substituted 3-benzyl-3H-1,2,3-triazolo[4,5-d]-pyrimidines of the general formula ##STR1## in which Ph represents a phenyl radical substituted by halogen, lower alkyl, trifluoromethyl and/or by cyano, R.sub.1 represents a free amino group or an amino group that is substituted aliphatically, cycloaliphatically, cycloaliphatically-aliphatically and/or by acyl, and R.sub.2 represents hydrogen, lower alkyl, a free amino group, or an amino group that is substituted aliphatically, cycloaliphaically, cycloaliphatically-aliphatically and/or by acyl, in free form or in form of a salt, with the proviso, that in a compound of formula I in free form, wherein R.sub.1 represents N,N-di-C.sub.1 -C.sub.6 -alkylamino in which the two N-C.sub.1 -C.sub.6 -alkyl groups may be the same or different, N-mono-C.sub.1 -C.sub.6 -alkylamino or amino, R.sub.2 is other than hydrogen and other than C.sub.1 - C.sub.6 -alkyl, if Ph represents a phenyl radical which is monosubstituted by halogen or by trifluoromethyl, and to compounds of formula I in free form wherein either Ph is o-fluorophenyl, R.sub.1 is N-mono-methylamino or amino, and R.sub.2 is hydrogen or methyl or wherein Ph is o-fluorophenyl, o-chlorophenyl or m-trifluoromethylphenyl, R.sub.1 is N,N-di-methylamino, and R.sub.2 is hydrogen or wherein Ph is m-fluorophenyl, p-fluorophenyl, o-chlorophenyl, o-trifluoromehylphenyl, m-trifluoromethylphenyl or p-trifluoromethylphenyl, R.sub.1 is N-mono-methylamino, and R.sub.2 is hydrogen. These compounds and salts can be used as pharmaceutical active ingredients and can be produced in a manner known per se.
该发明涉及3H-1,2,3-三唑并[4,5-d]嘧啶衍生物,特别是通式##STR1##的取代3-苄基-3H-1,2,3-三唑并[4,5-d]嘧啶。其中Ph代表被卤素、低碳基、三氟甲基和/或氰基取代的苯基基团,R.sub.1代表自由氨基或被脂肪基、环脂肪基、环脂肪基-脂肪基和/或酰基取代的氨基基团,R.sub.2代表氢、低碳基、自由氨基或被脂肪基、环脂肪基、环脂肪基-脂肪基和/或酰基取代的氨基基团,在自由形式或盐形式中。但是,在式I的自由形式化合物中,其中R.sub.1代表N,N-二C.sub.1-C.sub.6-烷基氨基,其中两个N-C.sub.1-C.sub.6烷基可能相同或不同,N-单C.sub.1-C.sub.6-烷基氨基或氨基,R.sub.2不是氢且不是C.sub.1-C.sub.6-烷基,如果Ph代表单卤代苯基或三氟甲基取代的苯基基团,则式I的自由形式化合物中,R.sub.2不是氢且不是C.sub.1-C.sub.6-烷基。该发明还涉及式I的自由形式化合物,其中Ph是o-氟苯基,R.sub.1是N-单甲基氨基或氨基,R.sub.2是氢或甲基,或者Ph是o-氟苯基,o-氯苯基或m-三氟甲基苯基,R.sub.1是N,N-二甲基氨基,R.sub.2是氢,或者Ph是m-氟苯基,p-氟苯基,o-氯苯基,o-三氟甲基苯基,m-三氟甲基苯基或p-三氟甲基苯基,R.sub.1是N-单甲基氨基,R.sub.2是氢。这些化合物和盐可用作药物活性成分,并可按已知方法制备。
