Laboratory studies by University of Alabama at Birmingham (UAB) researchers have shown that the drug triphendiol (NV-196) causes cell death in pancreatic and bile duct cancer cell lines, slows tumor growth and sensitizes tumors to chemotherapy treatments.
The findings were presented April 13 by Ewan Tytler, Ph.D., assistant professor in the UAB Department of Surgery, Gastrointestinal Section, at the annual meeting of the American Association for Cancer Research (AACR).
Tytler and his colleagues assessed the potential of triphendiol as a treatment for pancreatic adenocarcinoma using three representative cell lines. Triphendiol induced cell death in all three cell lines and pre-treating the cell lines with triphendiol increased the effectiveness of chemotherapy. Animal model studies showed that triphendiol in combination with chemotherapy inhibited tumor growth more effectively than each drug alone.
"In our laboratory studies, triphendiol is more potent at inducing cell death in pancreatic and bile duct cancer cells compared to the chemotherapy drug gemcitabine alone at up to 10-fold lower concentrations," Tytler said. "Of course, there is still much work to be done before this could become a treatment protocol for cancer patients but our findings are promising and validate the continued development of triphendiol as a possible pancreatic cancer therapy."
Triphendiol is being developed by Marshall Edwards Inc., as a treatment for late stage pancreatic and gall bladder cancer and recently received orphan drug status by the U.S. Food and Drug Administration. Triphendiol has been licensed by Novogen to Marshall Edwards Inc., who funded Tytler's study.
Tytler said that there is an urgent need for new pancreatic cancer treatments because fewer than 20 percent of patients are candidates for surgery. Current treatment is limited to chemotherapy, which is not always effective, as most tumors are resistant to or become resistant to the commonly used chemotherapy drug for pancreatic tumors, gemcitabine.
UAB research associate Xiaohong Wang, M.D. and UAB professor of Surgery J. Anthony Thompson, Ph.D., are co-authors of the study.Media Contact

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
