FIELD: organic chemistry, heterocyclic compounds, medicine. ^ SUBSTANCE: invention relates to dihydropyrimidine compounds of the formula (I*): their enantiomers, diastereoisomers and pharmaceutically acceptable salts wherein X1, X2 and X3 in common with atoms to which they are added form ring of the formula: or ; R1 represents hydrogen atom; R2, R3*, R4, R5, R6 and R7 have values given in cl. 1 of the invention claim. Also, invention relates to separate dihydropyrimidine compounds. Proposed compounds are inhibitors of calcium channel function being especially inhibitors of Kv1 subfamily of potential-overlapping K+-channels and especially inhibitors of Kv 1.5 that associated with super-rapid activating delayed cleaning K+-flow of Ikur and can be used in treatment of arrhythmia and Ikur-associated diseases. ^ EFFECT: valuable medicinal properties of compounds. ^ 15 cl, 589 ex |
