A high-throughput screen (HTS) with the National Institute of Health-Molecular Libraries Small Molecule Repository (NIH-MLSMR) compound collection identified a class of acyl hydrazones to be selectively lethal to breast cancer stem cell (CSC) enriched populations. Medicinal chemistry efforts were undertaken to optimize potency and selectivity of this class of compounds. The optimized compound was declared as a probe (ML239) with the NIH Molecular Libraries Program and displayed greater than 20-fold selective inhibition of the breast CSC-like cell line (HMLE_sh_Ecad) over the isogenic control line (HMLE_sh_GFP).

Abstract A cobalt(III) complex with pyridine-2-carbaldehyde 2,4-dichlorophenoxyacetylhydrazone (HL) is studied by elemental and thermogravimetric analyses, IR and electron spectroscopy, and single crystal XRD. It is found that regardless of the synthesis conditions cobalt(II) ions transform into cobalt(III), and two HL ligands are deprotonated in the complex and perform the tridentate chelating function

Abstract Nickel(II) complexes with pyridine-2-carbaldehyde 2,4-dichlorophenoxy acetylhydrazone (HL) are studied by elemental and thermogravimetric analyses, IR and electron spectroscopy, and X-ray diffraction analysis. It is established that ligands in the complex occur in deprotonated or molecular forms, depending on the synthesis conditions, thus forming [NiL2]·2H2O (I) and [Ni(HL)L](NO3)·2H2O (II) compounds
