The invention provides compounds of the formula (I):
or salts, tautomers, solvates and N-oxides thereof; wherein R
1
is hydroxy or hydrogen; R
2
is hydroxy; methoxy or hydrogen; provided that at least one of R
1
and R
2
is hydroxy; R
3
is selected from hydrogen; halogen; cyano; optionally substituted C
1-5
hydrocarbyl and optionally substituted C
1-5
hydrocarbyloxy; R
4
is selected from hydrogen; a group —(O)
n
—R
7
where n is 0 or 1 and R
7
is an optionally substituted acyclic C
1-5
hydrocarbyl group or a monocyclic carbocyclic or heterocyclic group having 3 to 7 ring members; halogen; cyano; hydroxy; amino; and optionally substituted mono- or di-C
1-5
hydrocarbylamino; or R
3
and R
4
together form a monocyclic carbocyclic or heterocyclic ring of 5 to 7 ring members; and NR
5
R
6
forms an optionally substituted bicyclic heterocyclic group having 8 to 12 ring members of which up to 5 ring members are heteroatoms selected from oxygen, nitrogen and sulphur.
The compounds have activity as Hsp90 inhibitors.
Compounds having the formula (I):
and in particular, those of subgenus VIIa
are disclosed as inhibits or modulators of the activity of the heat shock protein Hsp90. As such they are useful for treating cancer, particularly hematopoietic tumors of lymphoid or myeloid lineage, prostate cancer, lung cancer, gastrointestinal stromal tumor, breast cancer and melanoma.
