  Synthesis, SAR, and Biological Evaluation of Oximino-Piperidino-Piperidine Amides. 1. Orally Bioavailable CCR5 Receptor Antagonists with Potent Anti-HIV Activity

  摘要：

  We previously reported the discovery of 4-[(Z)-(4-bromophenyl)(ethoxyimino)methyl]-1'-[(2,4-dimethyl-3-pyridinyl)carbonyl] -4'-methyl-1,4'-bipiperidine N-oxide 1 (SCH 351125) as an orally bioavailable human CCR5 antagonist for the treatment of HIV-1 infection. Herein, we describe in detail the discovery of 1 from our initial lead compound as well as the synthesis and SAR studies directed toward optimization of substitution at the phenyl, oxime, and right-hand side amide groups in the oximino-piperidino-piperidine series. Substitutions (4-Br, 4-CF3, 4-OCF3, 4-SO2Me, and 4-Cl) at the phenyl group are well-tolerated, and small alkyl substitutions (Me, Et, Pr-n, Pr-i, and cyclopropyl methyl) at the oxime moiety are preferred for CCR5 antagonism. The 2,6-dimethylnicotinamide N-oxide moiety is the optimal choice for the right-hand side. Several compounds in this series, including compound 1, exhibited excellent antiviral activity in vitro. Compound 1, which has a favorable pharmacokinetic profile in rodents and primates, excellent oral bioavailability, and potent antiviral activity against a wide range of primary HIV-1 isolates, is a potentially promising new candidate for treatment of HIV-1 infection.

  Structure-activity studies on piperidino-piperidine 3 led to the discovery of SCH 351125 (1), a selective CCR5 antagonist with potent activity against RANTES binding (K-i = 2 nM), which possesses subnanomolar activity in blocking viral entry and has excellent antiviral potency versus a panel of primary HIV-1 viral isolates. Compound 1, which has good oral bioavailability in rats, dogs, and monkeys, is proposed as a potential therapeutic agent for the treatment of HIV-1 and has entered human clinical trials.
