<p>Compound of formula (I) wherein: A is a bicyclic heteroaryl, optionally substituted with one or more substituents; B is aryl or a mono or bicyclic heteroaryl, each of which can be optionally subsituted with one or more subsituents; Z is -X(CRaRb)aCO, -NH, -CO or the group X-(CH2)bCONH (CH2)cNH where X is oxygen, sulphur, amino, alkylamino or a direct bond, R?a and Rb¿ are independently hydrogen or C¿1-4? alkyl, a is an integer from 1 to 4, b is 1 or 2 and c is from 2 to 5, and; W is -NHCH(R?w¿)CO- or OC(Rw)CHNH where Rw is -CH¿2?CH(CH3)2-CH2CH2S(CH3) or CH2CH2S(O2)(CH3); q is 0 or 1 and when q is 0 Z is linked to the group W by the formation of an amide bond between Z and Y, and when q is 1 Z is linked to the group W by the formation of an amide bond between Z and W and W is linked to the group Y by the formation of an amide bond between W and Y; Y is a fragment derived from the C-terminus of a compound which inhibits the interaction between the integrin αIIbβ3 and its ligand fibrinogen; R?1¿ is hydrogen, C¿1-5?alkyl, C1-3 alkanoyl or C1-3 alkoxycarbonyl; or a pharmaceutically acceptable salt or in vivo hydrolysable derivative thereof.</p> |
