4-dihydroquinoxalin-2(1H)-one (J46), which contains a 3,4-dihydroquinoxalin-2(1H)-one core structure as a key fragment to inhibit JNK3. However, compound J46 displayed high DDR1 and EGFR (T790M, L858R) inhibition and poor physicochemical properties, especially clogD and water-solubility, in its biological studies. Herein, we optimized compound J46 by structure-based drug design and exploiting the selectivity and physicochemical
c-Jun N末端激酶3(JNK3)在多种疾病(包括神经退行性疾病,炎症性疾病,癌症,心血管疾病和代谢性疾病)中起关键作用。以前,我们已经确定了一种铅化合物(Z)-3-(2-(萘-1-基)-2-氧代亚乙基)-3,4-二氢喹喔啉-2(1 H)-一个(J46),其中包含3,4-二氢喹喔啉-2(1 H)-一个核心结构作为抑制JNK3的关键片段。但是,化合物J46在其生物学研究中显示出较高的DDR1和EGFR(T790M,L858R)抑制作用,以及较差的理化特性,尤其是clogD和水溶性。在这里,我们优化了化合物J46通过基于结构的药物设计和开发的选择性和各种弹头基团的物理化学性质,以获得化合物J46 - 37,其不仅表现出对JNK3的强效抑制,但也显示出超过50倍效力比DDR1和EGFR(T790M更好, L858R)。此外,通过分子对接和分子动力学模拟分析了新型合成的3,4-二氢喹喔啉-2(1
