Abstract:
Compounds of formula (I) where R2, each X, L, Y, Cy, Lp, D and n are as defined in the specification, are serine protease inhibitors useful as antithrombotic agents.
Abstract:
The invention relates to serine protease inhibitor compounds of fornula (I) where R1 is hydrogen, halo, cyano, nitro or hydroxyl, amino, alkoxy, alkyl amminoalkyl, hydroxyalkyl, thiol, alkylthio, aminosulphonyl alkoxyalkyl, alkoxycarbonyl, acyloxymethoxycabonyl or alkylamino optionally substituted by hydroxy, alkylamino, alkoxy, oxo, aryl, cycloalkyl, amino, halo, cyano, nitro, thiol, alkylthio, alkylsulphonyl, alkylsulphenyl, alkylsulphonamido, alkylaminosulphonyl, haloalkoxy and haloalkyl; R2 is hydrogen, halo, methyl amino, hydroxy, or oxo; and R is X—X—Y(R7)—L—Lp(D)n; wheren each X independently is a C, N, O or S atom or a CO, CR1, C(R1)2 or NR1 group, at least one X being C, CO, CR1 or a C(R1)2 group; Y (the &agr;-atom) is a nitrogen atom or a CR1 group or Y and L taken together form a cyclic group; R7 is a lipophilic group selected from alkyl, alkenyl, mono- or bi-cycloalkyl, aryl, heteroaryl, mono- or bicycloalkylalkyl, mono- or bicycloalkylakenyl, aralkyl, heteroaryl-alkyl, arylalkenyl, heteroarylalkenyl all optionally substituted by a group R1; L is an organic linker group containing 1 to 5 backbone atoms selected from C, N, O and S, or a branched alkyl or cyclic group; Lp is a lipophilic organic group selected from alkyl, heterocyclic, alkenyl, alkaryl cycloalkyl, polycycloalkyl, cycloalkenyl, aryl, aralkyl or haloalkyl group or a combination of two or more such groups optionally substituted by one or more of oxa, thia, aza or R1 groups; D is a hydrogen bond donor group; and n is 0, 1 or 2 and salts thereof.
