Patent
CA 2222960
The invention relates to an imidazo[1,5a]pyridine derived serine protease inhibitor comprising a unit having general formula (I) wherein R1 is hydrogen, lower alkyl or an acyl group; R2 is hydrogen or lower alkyl; R3 and R4 are independently hydrogen, lower alkyl or together form =CH-NR5R6, R5 and R6 being lower alkyl. The compounds are serine protease inhibitors and can be used for the treatment and prophylaxis of thrombosis and thrombin-associated diseases.
Cette invention concerne un inhibiteur de sérine protéase dérivé de imidazo[1,5a]pyridine, lequel inhibiteur comprend une unité correspondant à la formule générale (I) où R¿1? représente hydrogène, alkyle inférieur ou un groupe acyle; R¿2? représente hydrogène ou alkyle inférieur; R¿3? et R¿4? représentent indépendamment hydrogène, alkyle inférieur ou forment ensemble =CH-NR¿5?R¿6?, R¿5? et R¿6? représentant un alkyle inférieur. Ces composés sont des inhibiteurs de sérine protéase et peuvent être utilisés dans le traitement et la prévention de thromboses et de maladies associées à la thrombine.
