Induction of differentiation of the acute myeloid leukemia cell line (HL-60) by a securinine dimer.

ABSTRACT: Differentiation therapy has been successfully applied clinically in cases of acute promyelocytic leukemia (APL), but few differentiation-induction agents other than all-trans retinoic acid (ATRA) have been discovered clinically. Based on our previously reported neuritogenic differentiation activity of synthetic dimeric derivatives of securinine, we explored the leukemia differentiation-induction activity of such as compound, SN3-L6. It was found that SN3-L6 induces transdifferentiation of both acute myeloid leukemia (AML) and chronic myelogenous leukemia (CML) cells but unexpectedly, a new transdifferentiation pathway from APL cells to morphologically and immunologically normal megakaryocytes and platelets were discovered. SN3-L6 fails to induce transdifferentiation of ATRA-produced mature
