Design, Synthesis, and In Vitro Anticancer Activities of Diethylene Glycol Tethered Isatin‐1,2,3‐triazole‐coumarin Hybrids

A series of novel diethylene glycol tethered isatin‐1,2,3‐triazole‐coumarin hybrids 9a–l were designed, synthesized, and evaluated for their in vitro anticancer activities against HepG2 (liver carcinoma), Hela (cervical cancer), A549 (lung adenocarcinoma), DU145 (prostatic cancer), SKOV3 (ovarian carcinoma), MCF‐7 (breast cancer), and drug‐resistant MCF‐7/DOX (doxorubicin‐resistant MCF‐7) human cancer cell lines. The results showed that most of the synthesized hybrids exhibited considerable in vitro activities against the tested seven cancer cell lines, and these hybrids can be acted as starting points for further investigation.
