A method of inhibiting or effecting the activity of an integral receptor which comprises contacting an integrin with a compound of formula I, or a pharmaceutically acceptable salt thereof; General Formula I Wherein the ring may be of any configuration; Z is sulphur, oxygen, CH 2 , NH, NR A or hydrogen, in the case where Z is hydrogen then R 1 is not present, R A is selected from the set defined for R 1 to R 5 , X is oxygen or NR A providing that at least one X of General Formula I is NR A , X may also combine independently with one of R 1 to R 5 to form an azide, R 1 to R 5 are independently selected from the group comprising H, —(CO)R 6 or an alkyl, acyl, alkenyl, alkynyl, heteroalkyl, aryl, heteroaryl, arylalkyl or heteroarylalkyl substituent of 1 to 20 atoms, which is optionally substituted, and can be branched or linear wherein substituents may optionally be further substituted, wherein R 6 is selected from the group comprising an alkyl, acyl, alkenyl, alkynyl, heteroalkyl, aryl, heteroaryl, arylalkyl or heteroarylalkyl substituent of 1 to 20 atoms, which is optionally substituted, and can be branched or linear wherein substituents may optionally be further substituted, with the proviso that XR 2 or XR 3 or XR 4 or XR 5 is not NH 2 , with the further proviso that not more than one of R 2 to R 5 is hydrogen, where the group X is NR A and R A is not hydrogen, the groups R A and the corresponding group R 2 to R 5 may combine to form a cycle. |
