On the basis of the structures of small-molecule hits targeting the HIV-1 gp41, N-(4-carboxy-3-hydi-oxy)plieiiyl-2,5-dimethylpyl-role (2, NB-2), and N-(3-carboxy-4-chloro)phenylpyrrole (A(1), NB-64), 42 N-carboxyphenylpyrrole derivatives in two categories (A and B series) were designed and synthesized. We found that I I compounds exhibited promising anti-HIV-1 activity at micromolar level and their antiviral activity was correlated with their inhibitory activity on gp41 six-helix bundle formation, suggesting that these compounds block HIV fusion and entry by disrupting gp41 core formation. The structure-activity relationship and molecular docking analysis revealed that the carboxyl group Could interact with either Arg579 or Lys574 to form salt bridges and two methyl groups on the pyrrole ring were favorable for interaction with the residues in gp41 pocket. The most active compound, N-(3-carboxy-4-hydroxy)phenyl-2,5-dimethylpyrrole (A(12)), partially occupied the deep hydrophobic pocket, suggesting that enlarging the molecular size of A(12) could improve its binding affinity and anti-HIV-1 activity for further development as a small-molecule HIV fusion and entry inhibitor.
