COMPOUNDS CONTAINING A HYDROXYPHENYL MOIETY AND THEIR USE

The inventors have succeeded in developing urea, oxalamide, amide, thiourea, carbamate or ester compounds, in particular urea compounds, bearing two side groups, one of which carries a hydroxyphenyl or phenyl moiety, in particular a hydroxyphenyl moiety. These compounds have the advantage of inhibiting IRE1 RNase activity and sensitizing cancer cells, in particular GB cells, to chemotherapy. The present invention relates to urea, oxalamide, amide, thiourea, carbamate or ester compounds, in particular urea compounds containing a hydroxyphenyl or phenyl moiety, in particular a hydroxyphenyl moiety, including their pharmaceutically acceptable salts and solvates which are useful as sensitizers for chemotherapy of cancer cells, particularly in glioblastoma, and are useful as therapeutic compounds, particularly in the treatment of cancers that may be treated by alkylating agents, such as temozolomide.
