The present invention relates to a prodrug and application thereof in the treatment of viral and cancerous diseases. Said prodrug inhibits HCV NS5B of HBV polymerase, DNA polymerase, and HIV-1 of reverse transcriptase (RT) and is used for the treatment of hepatitis B and C infection in mammals.
The present invention also relates to the prodrugs of general formula 1 and stereoisomers thereof and their isotopically enriched analogs, pharmaceutically acceptable salts, hydrates, solvates, or crystalline or polycrystalline forms of the prodrugs of general formula 1 and stereoisomers thereof,
wherein n is 1 or 0;
Nuc is
R1 is hydrogen or methyl;
R2, R3 are optionally identical substituents selected from H, F, CI, CH3, OH provided that a solid line together with a dashed line above thereof (----) denote a carbon-carbon single bond (C-C), or R2 and R3 denote hydrogen provided that a solid line together with a dashed line above thereof (----) denote a carbon-carbon double bond (C=C); X is O, CH2 or C=CH2; Y is O, S, CH2 or a HO-CH group provided that a solid line together with a dashed line above thereof (----) denote a carbon-carbon single bond (C-C), or Y is a CH group provided that a solid line together with a dashed line above thereof (----) denote a carbon-carbon double bond (C=C).
本发明涉及一种前药及其在治疗病毒性和癌症性疾病中的应用。该前药抑制HBV聚合酶的HCV NS5B,DNA聚合酶和HIV-1的逆转录酶(RT),用于治疗哺乳动物中的乙型和丙型肝炎感染。
本发明还涉及一般式1及其立体异构体的前药及其同位素富集的类似物,药学上可接受的盐,水合物,溶剂合物,或一般式1及其立体异构体的晶体或多晶形式,
其中n为1或0;
Nuc为
R1为氢或甲基;
R2,R3为可选相同的取代基,选自H,F,CI,CH3,OH,前提是实线与其上方的虚线(----)表示碳-碳单键(C-C),或R2和R3表示氢,前提是实线与其上方的虚线(----)表示碳-碳双键(C=C);X为O,CH2或C=CH2;Y为O,S,CH2或HO-CH基团,前提是实线与其上方的虚线(----)表示碳-碳单键(C-C),或Y为CH基团,前提是实线与其上方的虚线(----)表示碳-碳双键(C=C)。
