The present invention relates to novel compounds according to the general Formulae (I, II, III, IV or V); wherein B is nucleoside base according to the structure Formula (VI); R is H, F, Cl, Br, I, C1-C4 alkyl (preferably CH3),-C=N, -C=C-Ra, Formula (VII); X is H, C1-C4 alkyl (preferably, CH3), F, Cl, Br or 1; Z is 0 or CH2, with the proviso that Z is CH2 and not O when the compound is according to general formula II, R3 is - C=C-H and R2 is H or a phosphate, diphosphate, triphosphate or phosphotriester group; R1 is H, an acyl group, a C1-C20 alkyl or an ether group; R2 is H, an acyl group, a CI-C20 alkyl or ether group, a phosphate, diphosphate, triphosphate, phosphodiester group or a Formula;(VIII) or Formula (IX) group; Nu is a radical of a biologically active antiviral compound such that an amino group or hydroxyl group from said biologically active antiviral compound forms a phosphate, phosphoramidate, carbonate or urethane group with the adjacent moiety; R8 is H, or a C1-C20 alkyl or ether group, preferably a C1-C12 alkyl group; k is 0-12, preferably, 0-2; R3 is selected from a C1- C4 alkyl (preferably, CH3), -(CH2)n-C=C-Ra, Formula (X) or Formula (XI); R3a and R3b are independently selected from H, F, C1, Br or I ; R4 and R5 are independently selected from H, F, C1, Br, I, OH, C1-C4 alkyl (preferably, CH3),-(CH2)n-C=C-Ra, Formula(XII) or Formula(XIII) with the proviso that R4 and R5 are not both H; Ra is H, F, Cl, Br, I, or -C1-C4 alkyl, preferably H or CH3; Y is H, F, C1, Br, I or -C1-C4 alkyl, preferably H or CH3; and n is 0, 1, 2,3, 4 or 5, preferably 0, 1 or 2; and their anomers, pharmaceutically acceptable salts, solvates, or polymorphs thereof. |
