Novel, Orally Bioavailable γ-Aminoamide CC Chemokine Receptor 2 (CCR2) Antagonists
摘要:
Through modification of a screening hit we have discovered a structurally distinct new lead, (2S)-N-[3,5-bis(trifluoromethyl)benzyl]-2-(4-fluorophenyl)-4-(4-phenylpiperidin-1-yl)butanamide (11), which has subsequently served as the departure point for an ongoing program targeting CCR2 antagonists. Optimization of 11 leading to antagonists 26 and 37 is described. Antagonist 26 was shown to have good oral bioavailability in rats. Antagonist 37 had a CCR2 IC50 of 59 nM and excellent potency in a functional assay measuring inhibition of MCP-1 induced monocyte chemotaxis (IC50 of 41 nM).

The first nonpeptide antagonists of the neurohypophyseal hormone, oxytocin (OT) are described. Derivatives of the spiroindenepiperidine ring system, these compounds include L-366,509, an orally bioavailable OT antagonist with good in vivo duration. The potential use of these agents for treatment of preterm labor and their significance as new nonpeptide ligands for peptide receptors are discussed.
