BENZOXAZINE DERIVATIVES AND BENZOTHIAZINE DERIVATIVES HAVING NOS-INHIBITORY AND ANTIOXIDANT PROPERTIES
The invention relates to compounds of formula (I) and to the tautomeric and isomeric forms and salts thereof, wherein: X represents O or S; R<1> represents -(CHR<9>)n-NR<7>-A-NR<8>-B, -(CHR<9>)n-NR<8>-B or -(CHR<9>)n-B; R<2> represents hydrogen or R<1> and R<2>, together with two adjacent carbon atoms, form a 5-, 6-, 7- or 8-member ring, which is monocyclic or bicyclic, saturated or unsaturated, and in which 1 or 2 CH2 groups can be replaced by oxygen or carbonyl, and which is substituted by -(CHR<9>)r-NR<7>-A-NR<8>-B, -(CHR<9>)n-B or -(CHR<9>)r-NR<8>-B; R<3> represents hydrogen or NR<15>R<16>; R<4> represents hydrogen or acyl; R<5> and R<6>, independent of one another, represent hydrogen, C3-7 cycloalkyl, phenyl, C1-6 alkyl, C2-6 alkenyl radicals or C2-6 alkynyl radicals, which can each be substituted by halogen, OH, O-C1-6 alkyl, SH, S-C1-6 alkyl, NR<15>R<16>, 5- or 6-member heteroaryl with 1-3 N, O or S atoms, phenyl or C3-7 cycloalkyl; A represents a straight-chain or branched C1-6 alkylene or -(CH2)p-Q-(CH2)q-, and; B represents (II) or (III). The invention also relates to the method for preparing said compounds and to their use in medicaments.
