CCI-007, a novel small molecule with cytotoxic activity against infant leukemia with MLL rearrangements.

ABSTRACT: There is an urgent need for the development of less toxic, more selective and targeted therapies for infants with leukemia characterized by translocation of the mixed lineage leukemia (MLL) gene. In this study, we performed a cell-based small molecule library screen on an infant MLL-rearranged (MLL-r) cell line, PER-485, in order to identify selective inhibitors for MLL-r leukemia. After screening initial hits for a cytotoxic effect against a panel of 30 cell lines including MLL-r and MLL wild-type (MLL-wt) leukemia, solid tumours and control cells, small molecule CCI-007 was identified as a compound that selectively and significantly decreased the viability of a subset of MLL-r and related leukemia cell lines with CALM-AF10 and SET-NUP214 translocation. CCI-007 induced a rapid caspase-dep
