New disubstituted bicyclic heterocycles of general formula
Ra—A—Het—B—Ar—E (I)
Compounds of the above general formula I, wherein E denotes an RbNH—C(═NH)— group, have valuable pharmacological properties, particularly a thrombin-inhibiting effect and the effect of prolonging thrombin time, and those wherein E denotes a cyano group, are valuable intermediates for preparing the other compounds of general formula I. Exemplary compounds of formula I are:
(a) 1-Methyl-2-[N-(4-amidinophenyl)-aminomethyl]-benzimidazol-5-yl-carboxylic acid-N-phenyl-N-(2-hydroxycarbonylethyl)-amide,
(b) 1-Methyl-2-[N-(4-amidinophenyl)-aminomethyl]-benzimidazol-5-yl-carboxylic acid-N-(2-pyridyl)-N-(hydroxycarbonylmethyl)-amide,
(c) 1-Methyl-2-[N-(4-amidino-2-methoxy-phenyl)-aminomethyl]-benzimidazol-5-yl-carboxylic acid-N-(2-pyridyl)-N-(hydroxycarbonylmethyl)-amide, and
(d) 1-Methyl-2-[N-[4-(N-n-hexyloxycarbonylamidino)phenyl]aminomethyl]-benzimidazol-5-yl-carboxylic acid-N-(2-pyridyl)-N-(2-ethoxycarbonylethyl) amide.
通式为Ra—A—Het—B—Ar—E的新型二取代的双环杂环化合物(I),其中E表示RbNH—C(═NH)—基团,具有有价值的药理学特性,特别是抑制凝血酶的作用和延长凝血酶时间的作用,其中E表示氰基的化合物是制备通式I其他化合物的有价值中间体。通式I的示例化合物包括:(a) 1-甲基-2-[N-(4-氨基苯基)-氨甲基]-苯并咪唑-5-基-羧酸-N-苯基-N-(2-羟基羧乙基)-酰胺,(b) 1-甲基-2-[N-(4-氨基苯基)-氨甲基]-苯并咪唑-5-基-羧酸-N-(2-吡啶基)-N-(羟基甲基)-酰胺,(c) 1-甲基-2-[N-(4-氨基-2-甲氧基苯基)-氨甲基]-苯并咪唑-5-基-羧酸-N-(2-吡啶基)-N-(羟基甲基)-酰胺,和(d) 1-甲基-2-[N-[4-(N-正己氧羰基酰胺基)苯基]氨甲基]-苯并咪唑-5-基-羧酸-N-(2-吡啶基)-N-(2-乙氧羰基乙基)酰胺。
