Drug candidates for inhibition of HIV-1 replication can target Src family kinases (SFK), such as Hck, that interact with Nef protein of the virus. Compounds characterized by such inhibitory activity were identified via an assay for kinase activity of an SFK in a Nef:SFK complex. Illustrative of inhibitors identified using the kinase assay are various 2,3-diaminoquinaxolines and furo[2,3-d]pyrimidines. The inventive inhibitors were found to arrest HIV-1 viral replication in vitro.

N,N-Dialkyl-1-naphthylamines substituted by alkyl groups R (R = Me, Et, i-Pr, t-Bu) in position 2 display anisochronous NMR signals owing to their twisted conformational arrangement. These conformers are enantiomerically related (conformational atropoisomers), and variable temperature NMR measurements allowed the enantiomerization barriers to be determined. The barriers increase with the increasing dimension of the substituents (covering the range 15.7-23.0 kcal mol-1), and the observed trend was reproduced by Molecular Mechanics calculations. The calculations also gave indications upon the structure of the conformers that correspond to energy minima. The final choice among the possible conformations could be achieved by comparing the computed interprotonic distances with the results of NOE experiments.
