Synthesis of Novel Phthalazinedione-Based Derivatives with Promising Cytotoxic, Anti-bacterial, and Molecular Docking Studies as VEGFR2 Inhibitors.

ABSTRACT: The parent ester methyl-3-[2-(4-oxo-3-phenyl-3,4-dihydro-phthalazin-1-yloxy)-acetylamino] has 18 compounds. The starting material for alkanoates, their corresponding hydrazides, hydrazones, and dipeptides were produced by chemoselective O-alkylation of 2-phenyl-2,3-dihydrophthalazine-1,4-dione with ethyl chloroacetate(4-oxo-3-phenyl-3,4-dihydro-phthalazin-1-yloxy) acetic acid methyl ester. The starting ester was hydrazinolyzed, then azide coupled with amino acid ester hydrochloride to produce several parent esters, and then hydrazinolyzed to produce parent hydrazides. These hydrazides were used to make a series of dipeptides by reacting them with amino acid ester hydrochloride under azide coupling conditions, and they were also condensed with a number of aldehydes to make the hydrazones.
