4-dimethyl-benzoic acid led to the selection of compound 4f for clinical studies. Compound 4f showed an IC50 of 123 nM for inhibition of PGE2-induced TNFα reduction in an ex vivo LPS-stimulated human whole blood assay (showing >10-fold increase over clinical compound CJ-023,423). Pharmacokinetic profile, selectivity and in vivo efficacy comparing 4f to NSAID diclofenac in the monoiodoacetic acid (MIA) pain
一系列3-甲基吡啶-2-羰基氨基-2,4-二甲基-苯甲酸的SAR持续优化使人们选择了用于临床研究的化合物4f。化合物4f在离体LPS刺激的人全血检测中,抑制PGE2诱导的TNFα降低的IC 50为123 nM(显示比临床化合物CJ-023,423增加10倍以上)。包括在单碘乙酸(MIA)疼痛模型和佐剂诱导的关节炎(AIA)炎症模型中比较4f与NSAID双氯芬酸的药代动力学,选择性和体内功效。
