A phenotypic screen identifies a compound series that induces differentiation of acute myeloid leukemia cells in vitro and shows anti-tumour effects in vivo

Induction of differentiation is a promising therapeutic strategy against acute myeloid leukemia. However, current differentiation therapies are effective only to specific patient populations. To identify novel differentiation agents with wider efficacy, we developed a phenotypic high-throughput screen with a range of genetically diverse cell lines. From the resulting hits, one chemical scaffold was optimised in terms of activity and physicochemical properties to yield OXS007417, which was also able to decrease tumour volume in a murine in vivo xenograft model.
