合成了二十一种新的(+)-松香酸类类似物,属于三类,例如烯胺,亚胺和吡唑。所有合成的化合物均通过其光谱数据(1 H NMR,13 C NMR,IR和HRMS)进行表征。通过使用SRB细胞增殖测定法评估了合成的化合物对一组包括HeLa(子宫颈),MDA-MB-231(乳腺),A549(肺)和MiaPaca(胰腺)的四种人类癌细胞系的抗增殖活性。筛选结果表明,所有合成的化合物均显示出比母体化合物更高的活性。最重要的是,化合物2e和4a对所有测试的癌细胞系均显示出强大的抗增殖活性。化合物2e和4a使细胞周期停滞在G2 / M期并诱导HeLa细胞凋亡。

diseases, such as Alzheimer's disease (AD). Uncontrollable neuroinflammation and tau pathology form a vicious circle that further aggravates AD progression. Herein, we reported the synthesis of usnic acid derivatives and evaluation of their inhibitory activities against tau-aggregation and neuroinflammation. The inhibitory activity of the derivatives against the self-fibrillation of the hexapeptide AcPHF6
enhanced activity than the parent compound. Most significantly, compounds 2e and 4a showed potent antiproliferative activity against all the cancer cell lines tested. Compounds 2e and 4a arrested the cell cycle in G2/M phase and inducedapoptosis in HeLa cells. In view of significant antiproliferative activity, compounds 2e and 4a can be considered as lead molecules for further development.[Formula:
