Dissertations and Theses
Coumarins are natural compounds that have various physiological and therapeutic properties, making them pharmacologically important. Combretastatin A-4 (CA-4) is a microtubule-binding agent that has potent cytotoxic effects against human cell lines. In CA-4 the trimethoxyarene moiety plays a crucial role in its carcinopreventive effect. Thus, we decided to synthesize novel, potential anti-cancer agents called 1,4-triazolyl combretacoumarins, by coupling different coumarins and the functionally relevant group of CA-4 i.e, the trimethoxyarene moiety, via a 1,2,3-triazolyl ring using a copper-catalyzed [3 + 2] azide-alkyne cycloaddition (CuAAC) reaction, which is a very atom-economical reaction. The coupling partners, 4-azidocoumarins, required for making these …
