Synthesis and QSAR Study of (4-Oxo-3-aryl-3,4-dihydro-quinazolin-2-ylsulfanyl)-propionic Acid arylidene/aryl-ethylidene-hydrazides via Microwave Assisted Solvent Free Reations

Abstract

In the present work, s-alkylated derivatives of thio-quinazolinone were obtained using Methyl 2-chloro propionate via a solvent-free microwave-assisted method. The alkylated thio quinazolinones were further sequentially condensed with hydrazine hydrate and different aromatic aldehydes to get the hydrazides, which were studied for QSAR. The synthesized compounds were subjected to a prediction of biological activities. A software application (PASS) was used for this purpose. . The relationship between structure and different biological activities was studied and the different derivatives were recommended for the screening of some specific activities like anti-tuberculosic, anti-mycobacterial & HDL cholesterol increasing activities.
