  Discovery of Bioavailable 4,4-Disubstituted Piperidines as Potent Ligands of the Chemokine Receptor 5 and Inhibitors of the Human Immunodeficiency Virus-1

  摘要：

  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.

  A free-radical approach has enabled the development of a synthetically versatile alkyl–(hetero)arylation of olefins. Alkyl and (hetero)aryl groups were added concurrently to a full suite of mono- to tetrasubstituted simple alkenes (i.e., without requiring directing or electronically activating groups) for the first time. Key advances also included the introduction of synthetically diversifiable alkyl

  自由基方法使得合成多功能的烯烃烷基（杂）芳基化得以发展。首次将烷基和(杂)芳基同时添加到全套单取代至四取代的简单烯烃中(即，不需要定向基团或电子活化基团)。关键进展还包括引入具有不同取代度的合成多样化烷基、在环状和无环环境中良好的非对映控制、添加具有路易斯碱性氮原子以及简单苯的具有生物价值的杂芳烃，以及生成叔或季苄基中心。这一转变的合成潜力通过利用它作为 oliceridine 简洁合成的关键步骤得到了证明，oliceridine 是一种新型止痛药，于 2020 年获得 FDA 批准。
