摘要:Tpl2 (Cot/map3K8) Is An Upstream Kinase Of Mek In The Erk Pathway. It Plays An Important Role In Tumor Necrosis Factor-Alpha (Tnf-Alpha) Production And Signaling. We Have Discovered That 8-Halo-4-(3-Chloro-4-Fluorophenylamino)-6-[(1H-[1,2,3]Triazol-4-Ylmethyl)-Amino]-Quinoline-3-Carbonitriles (4) Are Potent Inhibitors Of This Enzyme. In Order To Improve The Inhibition Of Tnf-Alpha Production In Lps-Stimulated Human Blood,A Series Of Analogs With A Variety Of Substitutions Around The Triazole Moiety Were Studied. We Found That A Cyclic Amine Group Appended To The Triazole Ring Could Considerably Enhance Potency,Aqueous Solubility,And Cell Membrane Permeability. Optimization Of These Cyclic Amine Groups Led To The Identification Of 8-Chloro-4-(3-Chloro-4-Fluorophenylamino)-6-((1-(1-Ethylpiperidin-4-yl)-1H-1,2,3-Triazol-4-yl) Methylamino)Quinoline-3-Carbonitrile (34). In A Lps-Stimulated Rat Inflammation Model,Compound 34 Showed Good Efficacy In Inhibiting Tnf-Alpha Production. (C) 2009 Elsevier Ltd. All Rights Reserved.
