The invention provides combinations comprising (or consisting essentially of) one or more ancillary compound(s) and a compound 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
hydrocarbyl-amino; 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 combinations have activity as Hsp90 inhibitors.
