-
, (2008/06/13)
A compound of formula (I) where D is a VLA-4 specificity determinant which does not impart significant IIB/IIIa activity; R41 is a group of the formula (V): U - (CH2)d - V - T wherein U is selected from oxygen, sulphur, a direct bond or —CH2O—, V is selected from nitrogen, oxygen, sulphur, S(O), S(O)2 or a direct bond, d is zero or a number from 1 to 4, and T is selected from a range of variables defined in the application; and other variables are defined in the application, or a pharmaceutically acceptable salt or in vivo hydrolysable derivative thereof. The compounds are useful in the treatment of disease mediated by the interaction between VCAM-1 and/or fibronectin and the integrin receptor α4β1. Pharmaceutical compositions and methods of use or treatment are also described and claimed.
