Design, Synthesis, and Evaluation of Tetraethylene Glycol‐Tethered Isatin–1,2,3‐Triazole–Coumarin Hybrids as Novel Anticancer Agents

Abstract

We report herein the design and synthesis of a series of novel tetraethylene glycol‐tethered isatin–1,2,3‐triazole–coumarin hybrids and evaluate their in vitro antitumor activities against seven common human cancer cell lines including drug‐resistant cell line. Results revealed that all the synthesized hybrids showed weak to moderate activities against the tested seven cancer cell lines. The structure–activity relationship was also discussed, and the enriched structure–activity relationship may pave the way for further rationale design of this kind of hybrids.
