...we investigated the preclinical activity of ME-344, a novel isoflavone OXPHOS inhibitor, on AML cell lines and relapsed/refractory (R/R) patient samples in vitro and examined the efficacy of ME-344 in combination with VEN in Ara-C sensitive and resistant AML cell lines and patient-derived xenografts (PDX) both in vitro and in vivo....The dual inhibition of OXPHOS/Bcl-2 reduced Mcl-1 levels and showed efficacy in Mcl-1 overexpressing and Ara-C resistant AML models.
