design, synthesis, and ability to inhibit p38α MAP kinase by a novel series of naphthyridine N-oxides will be described. Some of these compounds showed a significant reduction in the LPS-induced TNFα production in human whole blood. Structure–activity relationship studies revealed that N-oxide oxygen was essential for activity and was probably a determinant factor for its marked selectivity against
将描述通过一系列新的萘啶N-氧化物抑制p38αMAP激酶的设计,合成和能力。这些化合物中的一些显示出人全血中LPS诱导的TNFα产生的显着减少。结构-活性关系研究表明,N-氧对于活性至关重要,并且可能是其对其他相关激酶的显着选择性的决定因素。经过广泛的SAR练习,该系列的几种化合物被鉴定为非常有效的p38α抑制剂。在急性小鼠炎症模型中,已证明某些衍生物的体内功效可降低TNFα水平(ED 50当在LPS给药前1.5 h口服给药时,LPS诱导的TNFα产生= 0.5 mg / kg)。口服给药(ED 50 <1 mg / kg)时,在已确诊疾病的大鼠的慢性佐剂性关节炎慢性模型中进一步证明了口服功效。
