Synthesis and quantitative structure-activity relationship analysis of 2-(aryl or heteroaryl)quinolin-4-amines, a new class of anti-HIV-1 agents

Thirty-eight 2-(aryl or heteroaryl)quinolin-4-amines, N,N-disubstituted, N-monosubstituted, and without a substituent at the amino group have been synthesized with use of novel chemistries developed by us recently. Some of these derivatives show anti-HIV-1 activity at a concentration level of 1 microM and low cell toxicity in vitro. The most active and least toxic compounds are derivatives of 2-(3-pyridyl)quinoline. The results of the quantitative structure-activity relationship analyses, including several classical, linear regression correlations and a Free-Wilson approach of de novo model, provide guidelines for the design of new active compounds of this class.
