Abstract: The invention relates to novel 5-hydroxy-4-aminomethyl-1-cyclohexane or (cycloheptyl)-3-alkoxycarbonyl indole derivatives of general formula (I) and to pharmaceutically acceptable salts thereof exhibiting antiviral activity and to a method for the production thereof. The compounds can be used for treating and/or preventing such viral diseases as pig and bird flu. The invention also relates to a method for producing the compounds of general formula (I), wherein X is hydrogen, chlorine or iodine, n=1 or 2, R3 is C1-C5 alkyl, Alk is a C1-C6 alkyl group, R1 and R2 are independently selected from C1-C4 alkyl, mainly methyl, or the NR1R2 group means groups of formula (II).

Abstract: The invention relates to novel antiviral compounds of general formula (I), where B is —N(R)2 or —O—(CH2)nN(R)2 groups, in which n is a whole number selected from 0, 1, 2, 3 and 4, each R is independently selected from C1-4 alkyl and can be identical or different, or both groups R together with a nitrogen atom, to which they are bonded, form a 5-6-membered heterocyclic ring containing 1-2 heteroatoms selected from nitrogen, oxygen and sulphur, such as pyrrolidine, piperidine, piperazine, morpholine or thyomorpholine, at which each of above-mentioned heterocyclic rings can be substituted by C1-4 alkyl, phenyl, benzyl, phenetyl, a carbonylamino —COOC1-4 alkyl group or the carbonylamino —COOC1-4 alkyl group and phenyl, which also can be substituted and have substituents selected from halogen, C1-4 alkyl, C1-4 alkoxy, and alkyl in said groups can be linear or branched; R1 is C1-4 alkoxy, phenyl optionally substituted by C1-4 alkyl or C1-4 alkoxy, halogen atoms, naphthyl; R2 is C1-4 alkyl, —S-phenyl, —S-benzyl, —O-
