    • PURPOSE: Provided are novel 2,4-difluorobenzamide derivatives which are excellent in inhibition of the growth of both HBV and HCV, and thus used as prevention and treatment agents for HBV hepatitis and HCV hepatitis. also, provided are their pharmaceutically acceptable salts and their manufacturing method. CONSTITUTION: The 2,4-difluorobenzamide derivative is represented by the formula(1), wherein R1 is C1-C4 linear or branched alkyl group, hydroxy group, a C2-C6 alkylamino group, a 4-sulfamoylphenyl group, or a saturated or unsaturated 5 or 6 membered hetero cycle having 1-2 of hetero atoms selected from N, O and S; R2 is H or a C1-C3 linear or branched alkyl group; or R1 and R2 are bound together with 1-2 of hetero atoms selected from N, O and S to form a saturated or unsaturated 5, 6 or 7 membered hetero cycle, wherein the hetero cycle is a C1-C4 linear or branched alkyl group, or substituted or unsubstituted with a C1-C3 hydroxyalkyl group; and R3 is a 5-indazolyl group; and n is an integer of 0-4.
    • 目的:提供对HBV和HCV的生长抑制优异的新型2,4-二氟苯甲酰胺衍生物,因此用作HBV肝炎和HCV肝炎的预防和治疗剂。 还提供了它们的药学上可接受的盐及其制造方法。 构成:2,4-二氟苯甲酰胺衍生物由式(1)表示,其中R1是C1-C4直链或支链烷基,羟基,C2-C6烷基氨基,4-氨磺酰基苯基或饱和或 具有1-2个选自N,O和S的杂原子的不饱和5或6元杂环; R2是H或C1-C3直链或支链烷基; 或R 1和R 2与1-2个选自N,O和S的杂原子结合在一起以形成饱和或不饱和的5,6或7元杂环,其中杂环是C 1 -C 4直链或支链烷基 或者被C1-C3羟烷基取代或未取代; 并且R 3是5-吲唑基; n为0-4的整数。
