Furonaphthoquinones are promising skeletons for anticancer drug molecules. In particular, methoxylated furonaphthoquinones are characteristic constituents of Tabebuia plants. In this research, we synthesized the furonaphthoquinones by effective one-pot cascade reactions of 3-phenyliodonio-1,2,4-trioxo-1,2,3,4-tetrahydronaphthalenides with 3-butyn-2-ol in the presence of palladium and cuprous catalysts via Sonogashira coupling and intramolecular cyclization. Furthermore, we demonstrated that the synthetic furonaphthoquinones showed moderate cytotoxicity against human leukemia U937 and HL-60 cells. Our work highlights the importance of furonaphthoquinones as antileukemic agents.
呋喃萘醌类化合物是抗癌药物分子很有前途的骨架。特别是甲氧基化的呋喃萘醌类化合物是 Tabebuia 植物的特征成分。在这项研究中,我们在钯和亚铜催化剂存在下,通过 Sonogashira 偶联和分子内环化反应,以 3-苯基碘-1,2,4-三氧代-1,2,3,4-四氢萘化物和 3-丁炔-2-醇为原料,进行了有效的一锅级联反应,合成了呋喃萘醌类化合物。此外,我们还证明了合成的呋喃萘醌类化合物对人类白血病 U937 和 HL-60 细胞具有适度的细胞毒性。我们的工作凸显了呋喃并萘醌类化合物作为抗白血病药物的重要性。
