activation strategy was applied to the synthesis of potentially bioactive α-pyrone derivatives. As the result, three different scaffolds were quickly and conveniently generated, including thiophenes, pyrrole and indole derivatives. Among of them, eight α-pyrone derivatives showed potential effects to promote the uptake of LDL in HepG2 cells. Active unique α-pyrones compounds exhibiting potent in vitro
降脂被认为是降低动脉粥样硬化性心血管疾病(ASCVD)风险的最有效方法,其中动脉粥样硬化是最常见的原因。据报道,含有独特类型α-吡喃酮的天然产物可抑制动脉粥样硬化,其中α-吡喃酮可能被视为重要的药核。在这项研究中,将有效的一锅法分子内 C-H 活化策略应用于具有潜在生物活性的α-吡喃酮衍生物的合成。结果,快速方便地生成了三种不同的支架,包括噻吩、吡咯和吲哚衍生物。其中,八个α-pyrone 衍生物显示出促进 HepG2 细胞摄取 LDL 的潜在作用。活性独特的α-吡喃酮类化合物在体外和体内表现出强大的降脂作用,以及与LXR-IDOL-LDLR轴调节相关的新机制,即药理学靶向控制血浆胆固醇水平的新途径,在该论文中首次公开学习。
