VERWENDUNG VON OXAZOLO-(2,3-A)ISOINDOL-UND IMIDAZO(2,1-A)-ISOINDOL-DERIVATEN ALS ANTIVIRALE ARZNEIMITTEL SOWIE NEUE OXAZOLO(2,3-A)ISOINDOL-DERIVATEN

摘要

The invention concerns the use of oxazolo-[2,3-a]isoindole and iminazo[2,1-a]isoindole derivatives as antiviral drugs, as well as optically active derivatives, new oxazolo-[2,3-a]isoindole derivatives, a method for preparing them and drugs containing these compounds. In particular, the subject matter of the invention is the use of oxazolo-[2,3-a]isoindole and imidazo[2,1-a]isoindole derivatives of general formula (I) to produce antiviral drugs. In formula (I), X stands for an oxygen atom or a sulphur atom, the imino group =NH or a =N-C1-C5 alkylimino group, Y stands for an oxygen atom or the group NR<7>, wherein R<7> is a hydrogen atom or a C1-C6 alkyl residue or a C1-C6 acyl residue, R is a hydrogen atom, a straight-chain or branched, saturated or unsaturated aliphataic residue containing 1-9 carbon atoms, possibly substituted by phenyl, or a phenyl ring possibly substituted one or more times, or a carbocyclic or heterocyclic ring, R<1> and R<2> stand for a hydrogen atom, a straight-chain or branched, saturated or unsaturated aliphatic residue with 1 to 6 carbon atoms, R<3>-R<6> stand for hydrogen, C1-C6 alkyl, C1-C6 alkoxy, C1-C6 alkylmercapto, amino, C1-C6 alkylamino, di-C1-C6 alkylamino, halogen, cyano, hydroxy, carboxy, aminocarbonyl, substituted aminocarbonyl or C1-C6 alkoxycarbonyl. The invention also concerns their tautomers, enantiomers, diastereomers and physiologically acceptable salts.
