FIELD: medicine. SUBSTANCE: described are new 2-amino-4-phenyl-4-oxo-butyric acid of general formula IA: C<SB>1</SB>-C<SB>6</SB> wherein each of groups X and Y is independently hydrogen, halogen, trifluoromethyl, hydroxy, <EMI ID=0.73 HE=3 WI=9 TI=CHI> alkyl, benzyl, phenyl, naphthyl, <EMI ID=0.74 HE=3 WI=6 TI=CHI>, SO<SB>2</SB>R, SOR or <EMI ID=0.75 HE=3 WI=3 TI=CHI> wherein C<SB>1</SB>-C<SB>6</SB> is <EMI ID=0.76 HE=3 WI=6 TI=CHI> alkyl or benzyl; R is hydroxy, amino, hydroxy-amino, <EMI ID=0.77 HE=3 WI=9 TI=CHI>, <EMI ID=0.78 HE=6 WI=6 TI=CHI>, <EMI ID=0.79 HE=3 WI=9 TI=CHI> or <EMI ID=0.80 HE=3 WI=3 TI=CHI> wherein <EMI ID=0.81 HE=3 WI=9 TI=CHI> is as defined above, provided that R is not hydroxy when X and Y are simultaneously hydrogen; or X and Y are in position 3 or 4 of phenyl ring and are simultaneously hydroxy or <EMI ID=0.82 HE=3 WI=3 TI=CHI> group wherein <EMI ID=0.83 HE=21 WI=45 TI=CHI> is methyl, or one of groups X and Y is hydrogen and the other is in position 4 of phenyl ring and is hydroxy fluorine, chlorine, methyl, n-propyl or methoxy; or as individual isomers or mixtures thereof, or pharmaceutically acceptable salts thereof. 2-amino-4- phenyl-4-oxobutyric acid derivatives act as kinureninase and/or kinurenin-3-hydroxylase and are useful for prevention and/or treatment of diseases associated with neurodegeneration of tissues. Also described is pharmaceutical composition based on compounds of formula I. EFFECT: improved properties of the composition. 5 cl, 16 ex, 2 tbl
