title: Novel N-substituted benzimidazole CXCR4 antagonists as potential anti-HIV agents.
abstract: The lead optimization of a series of N-substituted benzimidazole CXCR4 antagonists is described. Side chain modifications and stereochemical optimization led to substantial improvements in potency and protein shift to afford compounds with low nanomolar anti-HIV activity.
