derivatives were isolated from the EtOH extract of Magnolia officinalis and the antiproliferative activity was evaluated on HCC827 (19del EGFR mutation), H1975 (L858 R/T790 M EGFR mutation), and H460 (KRAS mutation) cell lines. Among the isolated compounds, piperitylmagnolol (a 3-substituted magnolol derivative) showed the best antiproliferative activity against those three cell lines with the IC50 values
EGFR T790 M占非小细胞肺癌(NSCLC)对第一代EGFR酪氨酸激酶抑制剂(TKIs)耐药的病例的50%至60%。因此,鉴定具有抗TKIs抗性活性的新化合物具有重要价值。在这项研究中,20个厚朴酚和厚朴酚衍生物从的乙醇提取物中分离厚朴和抗增殖活性在HCC827(19del EGFR突变),H1975(L858 R / T790中号EGFR突变),和H460(KRAS突变)的细胞进行了评价线。在分离的化合物中,哌啶基厚朴酚(3取代的厚朴酚衍生物)对使用IC 50的这三种细胞系表现出最佳的抗增殖活性值分别为15.85、15.60和18.60μM,这为厚朴酚的结构修饰提供了方向。进一步的结构修饰导致了31个厚朴酚衍生物的合成,化合物A13,C1和C2表现出显着的广谱抗增殖活性,IC 50值范围为4.81至13.54μM,大约为4-和8-分别比厚朴酚和厚朴酚更强。而且,它们的水溶性提高了12-,400-和10
