Design, synthesis, and biological evaluation of novel piperidine-4-carboxamide derivatives as potent CCR5 inhibitors
摘要:
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 IC50 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. (C) 2013 Elsevier Masson SAS.

less reactive functional groups under catalyst-free conditions is an interesting aspect and requires a typical protocol. Herein, we report the synthesis of various primary, secondary, and tertiary amines through hydroboration of amides using pinacolborane under catalyst-free and solvent-freeconditions. The deoxygenative hydroboration of primary and secondary amides proceeded with excellent conversions

We report sodium trihydroxyaryl borates as the first robust tetracoordinate organoboron catalysts for reductive functionalization of CO2. These catalysts, easily synthesized from condensing boronic acids with metal hydroxides, activate main group element–hydrogen (E–H) bonds efficiently. In contrast to BX3 type boranes, boronic acids and metal-BAr4 salts, under transition metal-free conditions, sodium
