Exploration of Novel Urolithin C Derivatives as Non-Competitive Inhibitors of Liver Pyruvate Kinase
摘要:
肝脏丙酮酸激酶是一种脂肪在肝脏中逐渐积累并最终导致肝硬化的疾病,抑制肝脏丙酮酸激酶有助于阻止或逆转非酒精性脂肪肝。最近,有报道称尿石素 C 是开发肝丙酮酸激酶(PKL)异位抑制剂的新支架。本研究对尿石素 C 进行了全面的结构-活性分析。我们合成了 50 多种类似物,并测试了这些类似物所具有的化学特征。这些数据可为开发更强效、更具选择性的 PKL 异位抑制剂铺平道路。

The reaction of four substituted bis(3-alkoxybenzoyl) peroxides (1b-e) in neat phenols (2a-e) affords mainly 8-alkoxy-6H-dibenzo[b,d]pyran-6-ones (7) and ortho-benzoyloxylation products (4) of the phenol. Diaroyl peroxides without electron-releasing meta substituents afford essentially products 4. A mechanism involving monoelectronic oxidation of the phenol by the peroxide and biaryl coupling by preferential addition of the phenol radical cation to the ortho positions to the alkoxy group of the diaroyl peroxide is suggested.
