  Novel 4,4-Disubstituted Piperidine-Based C–C Chemokine Receptor-5 Inhibitors with High Potency against Human Immunodeficiency Virus-1 and an Improved human Ether-a-go-go Related Gene (hERG) Profile

  摘要：

  We recently described (J. Med. Chem. 2008, 51, 6538-6546) a novel class of CCR5 antagonists with strong anti-HIV potency. Herein, we detail SAR converting leads 1 and 2 to druglike molecules. The pivotal structural motif enabling this transition was the secondary sulfonamide substituent. Further fine-tuning of the substituent pattern in the sulfonamide paved the way to enhancing potency and bioavailability and minimizing hERG inhibition, resulting in discovery of clinical compound 122 (GSK163929).

  Abstract A four‐step, high‐yielding, kilogram‐scale protocol to prepare aldehyde 5 is reported. The key reaction is a mild, two‐step Cu2O‐mediated decarboxylation of cyanoester 3 that proceeds in excellent yield. The general applicability of this methodology has also been explored.

  We describe robust chemical approaches toward putative CCR5 scaffolds designed in our laboratories. Evaluation of analogues in the (125)I-[MIP-1 beta] binding and Ba-L-HOS antiviral assays resulted in the discovery of 64 and 68 in the 4,4-disubstitited piperidine class H, both potent CCR5 ligands (pIC(50) = 8.30 and 9.00, respectively) and HIV-1 inhibitors (pIC(50) = 7.80 and 7.84, respectively, in Ba-L-HOS assay). In addition, 64 and 68 were bioavailable in rodents, establishing them as lead molecules for further optimization toward CCR5 clinical candidates.
