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-phenyl, O-benzyl, wherein in each of the above-mentioned groups the phenyl ring is optionally substituted by C1-4 alkyl, C1-4 alkoxy, halogen atoms, or R2 is an —NR3R4 group, in which R3 and R4, each is independently selected from C1-4 alkyl and can be identical or different, or both R3 and R4 groups together with a nitrogen atom, to which they are bonded, form a 5-6-membered nitrogen-containing heterocyclic ring having the above mentioned value for the N(R)2 group; X is hydrogen or a halogen atom selected from Br, Cl, and I or pharmaceutically acceptable salts thereof. Intermediate products of general formula (II) and a method for producing the inventive compounds are also disclosed
本发明涉及一种通式(I)的新型抗病毒化合物,其中B是- N(R)2或-O-(
CH2)nN(R)2基团,其中n是从0、1、2、3和4中选择的整数,每个R独立地选择自C1-4烷基,并且可以相同或不同,或者R两个基团与它们所结合的氮原子一起形成一个含有1-2个氮、氧和
