This invention provides methods for treating, alleviating or reducing the incidence of a disease or condition comprising or arising from abnormal cell growth in a mammal, which comprise administering to the mammal a compound, salt, hydrate, tautomer or N-oxide according to formula (I):
wherein R
1
is hydroxy or hydrogen; R
2
is hydroxyl, 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 compounds have activity as Hsp90 inhibitors.
本发明提供了一种治疗、缓解或减少哺乳动物中由异常细胞生长引起或涉及的疾病或状况的方法,该方法包括向哺乳动物中给予根据公式(I)的化合物、盐、水合物、互变异构体或N-氧化物,其中R1为羟基或氢;R2为羟基、甲氧基或氢;但至少其中之一为羟基;R3选自氢、卤素、氰基、可选取代的C1-5烃基和可选取代的C1-5烃氧基;R4选自氢、—(O)n.R7基团(其中n为0或1,R7为可选取代的非环C1-5烃基或具有3至7个环成员的单环碳环或杂环基团)、卤素、氰基、羟基、氨基和可选取代的单或双C1-5烃基氨基;或R3和R4共同形成具有5至7个环成员的单环碳环或杂环环;以及NR5R6形成具有8至12个环成员(其中高达5个环成员为氧、氮和硫的杂原子)的可选取代的双环杂环基团。这些化合物具有作为Hsp90抑制剂的活性。
