The invention relates to a novel class of amide derivatives which act as thrombin inhibitors as described by formula (I), where R1 and R2, independently represent a group (a) or R1 and R2 together form a C3-7 heterocycloalkyl or heterocycloalkenyl group which may be optionally substituted by C1-6 alkyl, C1-4 alkoxy, halogen, carboxylic acid or a C1-4 carboxylic acid ester group; R3 represents hydrogen, C1-3 alkyl, halogen, or C1-2 alkoxy; R4, R5 and R6 independently represent hydrogen, or halogen; R7 represents hydrogen or C1-6 alkyl; R8 represents hydrogen, C3-7 cycloalkyl, C3-7 cycloalkenyl, C3-7 heterocycloalkyl, C3-7 heterocycloalkenyl, aryl or heteroaryl, which groups are optionally substituted by one or more groups selected from halogen, hydroxy, CN, C1-6 alkyl, C1-6 alkoxy, C1-6 acyloxy, NR9R10, NHCOR11, NHSO2R12, COR13, CO2R14, CONR15R16, and SO2NHR17; X represents a bond, a C1-6 alkyl chain, or a C3-6 alkenyl chain, where one or two nitrogen, oxygen, or sulfur atoms may be optionally contained within each chain, and the chains are optionally substituted by one or more groups selected from halogen, hydroxy, CN, C1-6 alkyl, C1-6 alkoxy, C1-6 acyloxy, NR9R10, NHCOR11, NHSO2R12, COR13, CO2R14, CONR15R16, and SO2NHR17; R9-R17 represent hydrogen, C1-6 alkyl, or R9 and R10 or R15 and R16 form a C3-7 heterocycloalkyl ring, or R12 additionally may represent trifluoromethyl; and pharmaceutically acceptable derivatives or solvates thereof, to processes for their preparation; and their use in the treatment of clinical conditions susceptible to amelioration by administration of a thrombin inhibitor.
该发明涉及一种新型酰胺衍生物类,其作为一种凝血酶抑制剂,其由式(I)描述,其中R1和R2独立地代表一个基团(a),或者R1和R2一起形成一个C3-7杂环烷基或杂环烯基基团,该基团可以选择性地被C1-6烷基、C1-4烷氧基、卤素、羧酸或C1-4羧酸酯基团取代;R3代表氢、C1-3烷基、卤素或C1-2烷氧基;R4、R5和R6独立地代表氢或卤素;R7代表氢或C1-6烷基;R8代表氢、C3-7环烷基、C3-7环烯基、C3-7杂环烷基、C3-7杂环烯基、芳基或杂芳基,这些基团可以选择性地被卤素、羟基、CN、C1-6烷基、C1-6烷氧基、C1-6酰氧基、NR9R10、NHCOR11、NHSO2R12、COR13、CO2R14、CONR15R16和SO2NHR17中的一个或多个基团取代;X代表一个键、一个C1-6烷基链或一个C3-6烯基链,其中每个链内可以选择性地包含一个或两个氮、氧或硫原子,并且这些链可以选择性地被卤素、羟基、CN、C1-6烷基、C1-6烷氧基、C1-6酰氧基、NR9R10、NHCOR11、NHSO2R12、COR13、CO2R14、CONR15R16和SO2NHR17中的一个或多个基团取代;R9-R17代表氢、C1-6烷基,或者R9和R10或R15和R16形成一个C3-7杂环烷基环,或者R12还可以表示三氟甲基;以及其药学上可接受的衍生物或溶剂,以及其制备方法;以及它们在治疗临床病况中的使用,该病况容易通过给予凝血酶抑制剂来改善。
