Inhibitors of the tissue factor/factor VIIa-induced coagulation: synthesis and in vitro evaluation of novel 2-aryl substituted pyrido[3,4-d][1,3]-, pyrido[2,3-d][1,3]-, pyrazino[2,3-d][1,3]-, pyrimido[4,5-d][1,3]-, pyrazolo[3,4-d][1,3]-, thieno[3,2-d][1,3]- and thieno[2,3-d][1,3]-oxazin-4-ones
摘要:
The synthesis of a series of 2-aryl substituted hetero annulated 1,3-oxazin-4-ones and their evaluation as specific inhibitors of the tissue factor (TF)/factor VIIa (FVIIa)-induced pathway of coagulation is reported. Inhibitory activities (IC50 values) in the range 0.64 to > 40 muM on the activation of factor X (FX) by the TF/FVIIa complex were found for compounds having one or two electronegative substituents such as F and NO2 in the 2-aryl substituent. Some of the compounds showed a selectivity ratio towards FX and thrombin of > 50, thus being similar in specificity to 2-aryl substituted 4H-3,1-benzoxazin-4-ones described as potential drugs for oral antithrombotic treatment without side effects, such as bleeding, which is observed especially with thrombin inhibitors.

The invention relates to the use of heterocyclic compounds with formulas (I) and (II), and pharmaceutical acceptable salts thereof, for the manufacture of a pharmaceutical preparation for treatment of coagulation-related diseases. The compounds are inhibitors of TF-FVIIa activity and thus show anticoagulant activity. The invention also relates to methods of treatment. The invention furthermore relates to novel compounds with the formula (I) or (II).
