Exploring Anticancer and (Bio)catalytic Activities of New Oxovanadium(V), Dioxomolybdenum(VI), and Copper(II) Complexes of Amide–Imine Conjugates

An amide–imine conjugate, (E)-N′-((2-hydroxynaphthalen-1-yl) methylene)–4-methylbenzohydrazide (PTANAP), derived from 4-methyl-benzoic acid hydrazide (PTA) and 2-hydroxynapthaldehyde, is explored to prepare dinuclear oxovanadium­(V), mononuclear dioxomolydenum­(VI), and Cu­(II) complexes. Single crystal X-ray structurally characterized complexes have been exploited as catalyst for oxidation of ethylbenzene, catechol, and o-aminophenol. The anticancer properties of the oxo-vanadium complex have been explored against human leukemia cell (K-562) and mouse lymphoma cells (2PK3).
