Pharmacophore Modelling and Synthesis of Quinoline-3-Carbohydrazide as Antioxidants

Abstract EN

From well-known antioxidants agents, we developed a first pharmacophore model containing four common chemical features: one aromatic ring and three hydrogen bond acceptors.

This model served as a template in virtual screening of Maybridge and NCI databases that resulted in selection of sixteen compounds.

The selected compounds showed a good antioxidant activity measured by three chemical tests: DPPH radical, OH∘ radical, and superoxide radical scavenging.

New synthetic compounds with a good correlation with the model were prepared, and some of them presented a good antioxidant activity.
