Application

di-2-Pyridyl ketone has been used in the preparation of unusual {Ni(II)(3)Ln(III)(μ-OR)(6)}(3+) complexes with a "star" topology. Its monoanionic form has been used in the synthesis of triangular Ni(2)M (M = lanthanide, Y) complexes.

Biochem/physiol Actions

The Schiff base ligands derived from di-2-pyridyl ketone exhibit antiproliferative activity in SK-N-MC neuroepithelioma (cancer) cells.

ABC transporters fulfill diverse physiological functions in different cellular localizations ranging from the plasma membrane to intracellular membranous compartments. Several ABC transporters have been spotted in the endolysosomal system, which consists of endosomes, autophagosomes, lysosomes, and lysosome-related organelles. In this
