FIELD: chemistry. ^ SUBSTANCE: present invention relates to novel substituted 2-(5-hydroxy-2-methyl-1H-indol-3-yl)acetic acids. The substituted 2-(5-hydroxy-2-methyl-1H-indol-3-yl)acetic acids of general formula 1 and their pharmaceutically acceptable salts and/or hydrates , where: R1 is an amino group substitute selected from hydrogen; optionally substituted C1-C5 alkyl; optionally substituted C1-C5 alkylsulphonyl, optionally substituted arylsulphonyl or optionally substituted heterocyclylsulphonyl; acyl; R2 is an alkyl substitute selected from hydrogen, substituted amino group, optionally substituted hydroxy group, substituted mercapto group, substituted alkylamino group; R3 is hydrogen, C1-C3 alkyl; R4 is a substitute selected from hydrogen, C1-C3 alkyl substituted with an amino group, optionally substituted with phenyl or heterocyclyl; R5 is one or more substitutes of the cyclic system selected from trifluoromethyl, carboxyl, alkyloxycarbonyl, possibly substituted aryl, heterocyclyl, substituted aminomethyl, cyano group, or R5 is hydrogen provided that when R1 is a substitute selected from hydroxy-substituted C1-C3 alkyl, amino-substituted C1-C3 alkyl, and R2, R3, R4 and R6 are as described above, or R2 is an alkyl substitute selected from substituted amino group, optionally substituted hydroxy group, substituted mercapto group, substituted alkylamino group, and R1, R3, R4 and R6 are as described above; or R5 is fluorine. ^ EFFECT: obtaining novel substituted 2-(5-hydroxy-2-methyl-1H-indol-3-yl)acetic acids which have antiviral activity, especially against the influenza virus and hepatitis C virus (HCV). ^ 19 cl, 3 tbl, 20 ex |
