Discovery of novel FMS kinase inhibitors as anti-inflammatory agents
摘要:
The optimization of the arylamide lead 2 resulted in identification of a highly potent series of 2,4-disubstituted arylamides. Compound 8 (FMS kinase IC50 = 0.0008 mu M) served as a proof-of-concept candidate in a collagen-induced model of arthritis in mice. (c) 2008 Elsevier Ltd. All rights reserved.

A broad survey of aromatic compounds with halogens positioned both ortho and para to activatinggroups was studied in SNAr reactions with piperidine. Regioselectivities varied with the substituent group and the polarity of the solvent. Many activatinggroups exhibited an overall bias toward ortho-substitution, and this led in nonpolar solvents to very high ortho selectivity. More polar solvents uniformly

boxamide (CPPC). Therefore, we synthesized radioligand [18F]1 by radiofluorination of chlorine-substituted precursor 7 in 13–15% decay-corrected radiochemical yield. Dynamic PET/CT images showed higher uptake in the lipopolysaccharide (LPS)-treated mouse brain than in control mouse brain. Ex vivo biodistribution study conducted at 45 min after radioligand injection showed that the brain uptake in LPS
