Three series of novel 2-methylpiperazine derivatives were designed and synthesized using a fragment-assembly strategy. Among them, six compounds (13, 16, 18, 22, 33, and 36) showed potent activity against CCR5 comparable to that of the positive control, maraviroc, in calcium mobilization assay. Moreover, some compounds were selected and further tested for their antiviral activity in HIV-1 single cycle assay. As a result, four compounds (13, 16, 33, and 36) showed antiviral activity at the nanomolar level. Additionally, the potent four compounds showed no cytotoxicity at a concentration of 10 μM.

Based on a putative 'Y shape' pharmacophore model of CCR5 inhibitors, a series of novel piperidine-4-carboxamide derivatives were designed and synthesized using a group-reverse strategy. Among synthesized target compounds, 16g (IC50 = 25.73 nM) and 16i (IC50 = 25.53 nM) showed equivalent inhibitory activity against CCR5 to that of the positive control maraviroc (IC50 = 25.43 nM) in calcium mobilization assay. Selected compounds were further tested for their antiviral activity in HIV-1 single cycle assay. Two compounds, 16g and 16i, displayed antiviral activity with IC 50 values of 73.01 nM and 94.10 nM, respectively. Additionally, the pharmacokinetic properties and inhibitory potency against hERG of 16g were evaluated, providing a foundation for ongoing optimization.
