TRYPSIN-LIKE SERINE PROTEASE INHIBITORS, THEIR PREPARATION AND USE AS SELECTIVE INHIBITORS OF THE CLOTTING FACTORS IIA AND XA

摘要

The invention provides methods of making and using compounds of the formula (I) or a pharmaceutically acceptable salt thereof; wherein n is an integer between 1 and 2 inclusively; m is an integer between 0 and 2 inclusively; X is selected from the group consisting of CH or N; R1 is selected from the group consisting of -CH2NH2, and (Formula (II)); R2 is selected from the group consisting of -H, -OH, -NH2 and acetyl; R3 is selected from the group consisting of -H, benzyloxycarbonyl and benzyisulfonyl;and R4 is selected from the group consisting of -OH, (Formulae (III), (IV), (V), (VI)), wherein p is an integer between 0 and 2 inclusively, Y is selected from the group consisting of -0-, -S-, -S(=0)-, -S02-, methylene, -CH(OH)-, -CH(NH2)-, -CH(CH2-OH)-, -CH(CH2- NH2)- or -N(R6)-, R5 is selected from the group consisting of -H or a simple (C1-C3) alkyl and R6 is selected from the group consisting of -H, a simple (C1-C3) alkyl or a simple (C1-C3) acyl. These compounds are useful as anticoagulant agents as a result of their selective dual inhibition of thrombin and prothrombinase.
