exploring new drugs that specifically directly activate Wnt is worthwhile to obtain new anti-vitiligo agents. In this work, two portions design and synthesis were put into effect. firstly, 17 phenanthridine derivatives with C-4 substitutes were designed and synthesized, which compounds 4, 6, 12, 13 served as H-acceptor with protein showed enhance melanogenesis activity; Secondly, 7 hybrid new scaffolds
人类长期患有白癜风。靶向白癜风药物尚未获得批准。Wnt/ β -catenin信号的激活在白癜风的治疗应用中具有潜力,因此探索特异性直接激活Wnt的新药对于获得新的抗白癜风药物是值得的。在这项工作中,设计和综合两部分进行。首先,设计合成了17个C- 4取代的菲啶衍生物,其中化合物4、6、12、13作为H-受体与蛋白质具有增强的黑素生成活性;其次,设计合成了7个杂化新的scaffolds,scaffold hopping化合物36芳香苯被C环上的吡唑取代,增强了黑色素生成和酪氨酸酶活性;最后也是最重要的,对化合物36进行了综合优化和SAR,化合物41和43在C-7位共享酚羟基或3-甲基-吡啶取代物,显着提高了黑素生成能力和酪氨酸酶活性。化合物43被鉴定为通过靶向Axin特异性激活 Wnt/ β -catenin 信号通路的新型抗白癜风药物. 构效关系分析表明,C-4位的H-受体取代和C-7位
