Background:
Despite the progress achieved by anti-retroviral drug research in the last decades, the discovery of novel compounds endowed with selective antiviral activity and reduced side effects is still a necessity. At present, the most urgent requirement includes the improvement of HIV (Human Immunodeficiency Virus) prevention and sexual transmission and the development of new drugs to treat the chronic lifelong infection.
Methods:
Six chloro-1,4-dimethyl-9H-carbazoles (2a,b-4a,b) have been prepared following opportunely modified known chemical procedures and tested in luciferase and Escherichia coli β-galactosidase expressing CD4⁺, CXCR4⁺, CCR5⁺ TZM-bl cells.
Results And Conclusion:
a preliminary biological investigation on the synthesized small series of chloro-1,4-dimethyl-9H-carbazoles has been carried out. Among all tested compounds, a nitro-derivative (3b) showed the most interesting profile representing a suitable lead for the development of novel anti-HIV drugs.

Conjugate Addition (1,4-Addition) vs Direct Addition (1,2-Addition)
Conjugate addition results in a thermodynamically stable product. The reaction retains the stronger C=O bond at the expense of the weaker C=C π bond. The process is slow as the β carbon is less electrophilic than the carbonyl carbon.
