Researchers successfully synthesize cancer agent thapsigargin

Queen’s University researchers have successfully synthesized the anticancer agent thapsigargin, which could right now open the door to the creation of brand-new cancer drugs.


The team of P. Andrew Evans (Chemistry) along with also his graduate student Dezhi Chen developed an efficient route to thapsigargin in only 12 steps.

“The first successful synthesis of thapsigargin required 42 steps, which was accomplished by at least 10 co-workers over a 10 year period,” says Dr. Evans. “What Dezhi did will be impressive by any measure. He devised a brand-new route to This kind of important agent along with also successfully implemented his idea to complete a 12 step synthesis in only nine months.”

Thapsigargin was isolated by a wild poisonous plant, which will be commonly known as the deadly carrot, in 1978. Despite numerous attempts to synthesize, the complexity of the molecule made This kind of very challenging.

A key feature with thapsigargin will be in which This kind of kills both slow along with also fast-growth cancer cells by inhibiting an enzyme in which controls essential calcium balance inside cells.

With the anticancer drug Mipsagargin entering late-stage clinical trials, Dr. Evans says “This kind of’s estimated in which more than one metric ton of thapsigargin will be required per year.”

The prodrug Mipsagargin will be being tested for the treatment of some of most challenging cancers, for example liver, brain, kidney along with also prostate cancer, thereby doing This kind of an exciting prospect.

“The efficient synthesis of This kind of molecule will be critical as relying on the isolation by a plant growing inside the wild will be not a sound strategy,” says Dr. Evans.

“The plant will be resistant to cultivation in natural or greenhouse conditions, which coupled to the low yielding along with also tedious isolation makes our approach a timely development. With our process we can make thapsigargin much more readily available that has a more efficient process. We have also opened up This kind of area for the preparation of simplified analogues.”

The research was recently published in Journal of the American Chemical Society.
