The invention provides a compound of formula (0):
or a pharmaceutically acceptable salt, N-oxide or tautomer thereof; wherein:
n is 1 or 2;
X is CH or N;
Y is selected from CH and C—F;
Z is selected from C—Rz and N;
R1 is selected from:
-(Alk1)t-Cyc1; wherein t is 0 or 1;
Optionally substituted C1-6 acyclic hydrocarbon groups
R2 is selected from hydrogen; halogen; and C1-3 hydrocarbon groups optionally substituted with one or more fluorine atoms;
R3 is hydrogen or a group L1-R7;
R4 is selected from hydrogen; methoxy; and optionally substituted C1-3 alkyl; and
R4a is selected from hydrogen and a C1-3 alkyl group;
wherein Rz, Alk1, Cyc1, L1 and R7 are defined herein;
provided that the compound is other than 6-benzyl-3-2-[(2-methylpyrimidin-4-yl)amino]pyridin-4-yl}-7,8-dihydro-1,6-naphthyridin-5(6H)-one and 3-2-[(2-methylpyrimidin-4-yl)amino]pyridin-4-yl}-7,8-dihydro-1,6-naphthyridin-5(6H)-one and salts and tautomers thereof.
The compounds are inhibitors of ERK1/2 kinases and will be useful in the treatment of ERK1/2-mediated conditions. The compounds are therefore useful in therapy, in particular in the treatment of cancer.
