Abstract

Acute myeloid leukemia (AML) is the second most prevalent and fatal form of leukemia. The growth of AML cells harboring oncogenic MLL rearrangements relies on the YEATS domain-containing protein ENL. Many small molecule inhibitors targeting ENL have been developed. To prioritize these inhibitors for in vivo studies, a NanoBRET system was introduced to evaluate their cellular permeability and potency. This screening identified inhibitor 13 as a promising candidate. This inhibitor has remarkable metabolic stability and potent antiproliferative effects on MLL-fusion leukemia cell lines. In AML-xenografted mice, inhibitor 13 significantly improved survival. Subsequent optimization efforts led to the development of SR-C-107 (R), which exhibited strong activity against AML both at the cellular level (CC50 (MOLM-13): 1.25 ± 0.18 μM; CC50 (MV4-11): 0.81 ± 0.15 μM) and in vivo. These findings establish SR-C-107 (R) as a compelling candidate for AML treatment and lay the groundwork for the development of next-generation AML inhibitors.
