  Orally Bioavailable Competitive CCR5 Antagonists

  摘要：

  The chemokine receptor CCR5 plays an important role in inflammatory and autoimmune disorders as well as in transplant rejection by affecting the trafficking of effector T cells and monocytes to diseased tissues. Antagonists of CCR5 are believed to be of potential therapeutic value for the disorders mentioned above and HIV infection. Here we report on the structure-activity relationship of a new series of highly potent and selective competitive CCR5 antagonists. While all compounds tested were inactive on rodent CCR5, this series includes compounds that cross-react with the cynomolgus monkey (cyno) receptor. One of these compounds, i.e., 26n, has good PK properties in cynos, and its overall favorable profile makes it a promising candidate for in vivo profiling in transplantation and other disease models.

  Piperazine-based CCR5 antagonists as HIV-1 inhibitors. III: synthesis, antiviral and pharmacokinetic profiles of symmetrical heteroaryl carboxamides

  摘要：

  The unsymmetrical nicotinamide-N-oxide moiety in compound I was replaced with symmetrical isonicotinamides as well as 4,6-dimethyl pyrimidine-5-carboxamides. Compound 16 from the latter set reduced the number of rotamers, improved potency of inhibiting UIV entry, slightly diminished the affinity for the muscarine receptors and showed very good oral absorption.

  In its several embodiments, this invention discloses a novel process to prepare the compounds of Formula 3: wherein R 1 is lower alkyl, and R 2 and R 3 can be the same or different, each being independently selected from the group consisting of alkyl, aryl and aralkyl; said process being carried out in a suitable solvent with at least one tert-amine carboxylate salt catalyst. The compounds of formula 3 are chemical intermediates useful for the synthesis of various heterocyclic compounds. These heterocyclic compounds are in turn useful precursors for diverse pharmaceutical, herbicidal and insecticidal agents. In particular, these intermediates are useful precursors to a variety of CCR5 inhibitors.
