Melanoma treatment options 1 step closer

21.10.2009
A targeted chemotherapy for the treatment of skin cancer is one step closer, after a team of University of Alberta researchers successfully synthesized a natural substance that shows exceptional potential to specifically treat this often fatal disease.

U of A chemistry professor Dennis Hall said after three years of work, his research team has successfully produced the substance called Palmerolide A.

"The potency of palmerolide is exceptional and melanoma is a very aggressive cancer for which there is almost no chemotherapeutic recourse," said Hall. "Natural substances like palmerolide offer real hope for such treatments.

"Current chemotherapy as an overall strategy is not very effective in treating melanoma. Less than a quarter of patients respond to chemotherapy and it typically only works for less than a year, and it has little to no effect on survival time. Palmerolide A as a targeted therapy may prove to be more effective [for treatment] with less toxicity," said Hall.

"One of the problems with most cancer drugs is the lack of selectivity for cancer cells versus normal cells. Preliminary data for Palmerolide A looks very promising in terms of solving this issue," he said.

"For commercialization, the structure needs to be made more 'drug-like;' smaller and more water-soluble, while preserving the potency," said Hall, who is optimistic that his U of A team is moving forward in the race to develop a treatment for melanoma.

Hall's research findings were recently published in the Journal of the American Chemical Society.

Dennis Hall is available for interviews on Wednesday, Oct. 21. Please Contact Wanda Vivequin..

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: Lining up surprising behaviors of superconductor with one of the world's strongest magnets

Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...
