Patent ID: 7842704

Claim:
A compound of formula I: wherein one of G 1 and G 2 represents NH and the other represents S, NH, O or CH 2 ; W represents O or NW a ; where W a is hydrogen or (1-4C)alkyl; each R 1 is independently selected from (1-4C)alkyl, (2-4C)alkenyl, (2-4C)alkynyl, (3-6C)cycloalkyl, cyano, halo, —OR 1a , —C(O)OR 1b , —SR 1c , —S(O)R 1d , —S(O) 2 R 1e and —NR 1f R 1g ; where each of R 1a , R 1b , R 1c , R 1d , R 1e , R 1f and R 1g ; is independently hydrogen, (1-4C)alkyl or phenyl-(1-4C)alkyl; each R 2 is independently selected from (1-4C)alkyl, (2-4C)alkenyl, (2-4C)alkynyl, (3-6C)cycloalkyl, cyano, halo, —OR 2a ,—C(O)OR 2b , —SR 2c , —S(O)R 2d , —S(O) 2 R 2e and —NR 2f R 2g ; where each of R 2a , R 2b , R 2c , R 2d , R 2e , R 2f and R 2g is independently hydrogen, (1-4C)alkyl or phenyl-(1-4C)alkyl; each R 3 is independently selected from (1-4C)alkyl, (2-4C)alkenyl, (2-4C)alkynyl, (3-6C)cycloalkyl, cyano, halo, —OR 3a , —C(O)OR 3b , —SR 3c , —S(O)R 3d , —S(O) 2 R 3e and —NR 3f R 3g ; or two R 3 groups are joined to form (1-3C)alkylene, (2-3C)alkenylene or oxiran-2,3-diyl; where each of R 3a , R 3b , R 3c , R 3d , R 3e , R 3f and R 3g is independently hydrogen or (1-4C)alkyl; R 4 represents a divalent hydrocarbon group containing from 4 to 28 carbon atoms and optionally containing from 1 to 10 heteroatoms selected independently from halo, oxygen, nitrogen and sulfur, provided that the number of contiguous atoms in the shortest chain between the two nitrogen atoms to which R 4 is attached is in the range of from 4 to 16; R 5 represents hydrogen or (1-4C)alkyl; R 6 represents hydrogen or hydroxyl; each R 7a and R 7b is independently selected from hydrogen, (1-4C)alkyl, hydroxy and fluoro; a is 0 or an integer of from 1 to 3; b is 0 or an integer of from 1 to 3; c is 0 or an integer of from 1 to 4; d is 0 or an integer of from 1 to 5; and m is 0 or an integer of from 1 to 3; or a pharmaceutically acceptable salt or stereoisomer thereof.
