Killing Hard to Treat Cancers

The new compound called ERX-41 kills a broad spectrum of hard-to-treat cancers.

A new molecule created by a researcher at the University of Texas at Dallas kills a variety of difficult-to-treat cancers, including triple-negative breast cancer, by taking advantage of a weakness in cells that was not previously targeted by existing drugs.

The research, which was conducted using isolated cells, human cancer tissue, and mouse-grown human cancers, was recently published in Nature Cancer.

A co-corresponding author of the study and an associate professor of chemistry and biochemistry in the School of Natural Sciences and Mathematics at the University of Texas at Dallas, Dr. Jung-Mo Ahn has dedicated more than ten years of his career to developing small molecules that target protein-protein interactions in cells. He previously created potential therapeutic candidate compounds for treatment-resistant prostate cancer and breast cancer using a method called structure-based rational drug design.

In the current work, Ahn and his colleagues tested a novel compound he synthesized called ERX-41 for its effects against breast cancer cells, both those that contain estrogen receptors (ERs) and those that do not. While there are effective treatments available for patients with ER-positive breast cancer, there are few treatment options for patients with triple-negative breast cancer (TNBC), which lacks receptors for estrogen, progesterone, and human epidermal growth factor 2. TNBC generally affects women under 40 and has poorer outcomes than other types of breast cancer.   READ MORE...
