potency was investigated. Several anilines were identified as providing potent, reversible pan-erbB inhibition. Optimum 4- and 6-substituents with known 7-substituents provided preferred irreversible inhibitors for pharmacodynamic testing in vivo. Quinazoline 54 and pyrido[3,4-d]pyrimidine 71 were identified as clearly superior to canertinib. Both compounds possess a piperidinyl crotonamide Michael acceptor
确定了一系列不可逆的pan-erbB抑制剂canertinib的基于喹唑啉和吡啶并[3,4- d ]嘧啶的类似物,确定了与erbB1,erbB2和erbB4抑制相关的构效关系。测定带有环胺的巴豆酰胺可在肝微粒体和肝细胞测定中快速抑制细胞erbB1自磷酸化并具有良好的代谢稳定性。研究了4-苯胺基取代对pan-erbB抑制效能的影响。几种苯胺被鉴定为提供有效的,可逆的pan-erbB抑制作用。具有已知7位取代基的最佳4位和6位取代基为体内药效学测试提供了首选的不可逆抑制剂。喹唑啉54和吡啶并[3,4- d ]嘧啶确定有71例明显优于canertinib。两种化合物均具有哌啶基巴豆酰胺迈克尔受体和3-氯-4-氟苯胺,分别表明它们分别为优化的6-和4-取代基。化合物54和71在三个物种中的药代动力学比较选择了化合物54作为优选的候选物。已为化合物54(PF-00299804)命名为dacomitinib,目前正在临床评估中。
A series of molecules with dual inhibitory activities on calpain and lipid peroxidation were synthesized. These hybrid compounds were built on the calpain pharmacophore 2-hydroxytetrahydrofuran linked to a set of antioxidants via a L-leucine linker. Compound 7, the most potent in cellular calpain and lipid peroxidation inhibitions, provided effective protection against glial cell death induced by maitotoxin. (C) 2004 Elsevier Ltd.
