Cyclocondensation reaction of heterocyclic carbonyl compounds, Part XIII: Synthesis and cytotoxic activity of some 3,7-diaryl-5-(3,4,5-trimethoxyphenyl)pyrazolo[4,3-e][1,2,4]triazines

Add time:07/17/2019    Source:sciencedirect.com

A series of the 3,7-diaryl-5-(3,4,5-trimethoxyphenyl)pyrazolo[4,3-e][1,2,4]triazines (17a–20f) have been synthesized in five steps. The cytotoxic activity of all of the newly synthesized compounds has been tested in vitro against five cancer cell lines. Several compounds demonstrated significant broad cytotoxic activity in low micromolar range, while others were selectively active against lung adenocarcinoma cell line A549.
