  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).

  3-Phenyl-5-methyl-2H,5H-furan-2-ones: tuning antifungal activity by varying substituents on the phenyl ring

  摘要：

  A series of racemic 3-phenyl-5-methyl-2H,5H-furan-2-ones related to a natural product, (-)incrustoporine, was synthesized, and their antifungal activity evaluated. The key structural feature, furanone ring, was closed via H2SO4-mediated cyclization of 3-phenylpent-4-enoic acids. The compounds displayed antifungal activity, especially against filamentous fungi. Expressed as the minimum inhibition concentration (MIC) in mu mol/L, the activity of the most promising derivative against Absidia corymbifera matched that of ketoconazole (31.25 mu mol/L). In terms of mu g/mL, the substance was more active (7.6 mu g/mL) than this standard antifungal drug (16.6 mu g/mL). (C) 2000 Elsevier Science Ltd. All rights reserved.

  The concomitant generation of a nucleophilic and an electrophilic site from unsaturated Weinreb amide by using Cp2Zr(H)Cl) as the unique reagent was developed to promote a cyclisation reaction. The access to trans-2-substituted cyclopentanols or cyclopentylhydroxylamines can be selectively driven by a judicious choice of the cyclisation promotor. An access to cis-3-substituted is also described.

  (2S)-2-(3,4-Dichlorophenyl)-1-[N-(methyl)-N-(phenylsulfonyl)amino]-4-[spiro(2,3-dihydrobenzthiophene-3,4'-piperidin-1'-yl)]butane S-oxide (3) has been identified as a potent CCR5 antagonist lead structure having an IC50 = 35 nM. Herein, we describe the structure-activity relationship studies directed toward the requirement for and optimization of the C-2 phenyl fragment. The phenyl was found to be important for CCR5 antagonism and substitution was limited to small moieties at the 3-position (13 and 16. X=H, 3-F, 3-Cl, 3-Me).
