Background: A series of novel 3-(1,3-dioxoisoindolin-2-yl)-N-substituted phenyl benzamide derivatives was synthesized and tested in vitro against human immunodeficiency virus type-1 Integrase (HIV-1 IN).

Methods: Out of the 18 analogues, six (compounds 16c, 16h, 16i, 16m, 16n and 16r) showed significant inhibition of strand transfer by HIV-1 integrase. For these six compounds. IC50 was below 5.0 µM. In silico docking studies revealed that the presence of 2-phenyl isoindoline-1,3-dione motif was essential as it was found to interact with active site magnesium.

Results: To further confirm the results, cell-based HIV-1 and HIV-2 inhibitory assay was carried out.

Conclusion: These compounds possess structural features not seen in previously reported HIV-1 integrase inhibitors and thus can help further optimization of anti-HIV-1 integrase activity.

Keywords: HIV-1 integrase, strand transfer inhibitors, N-substituted phenyl benzamide, AIDS, IN inhibitors, docking studies.
