Using an ancient Chinese folk remedy as a model, researchers at The Johns Hopkins University in Baltimore have designed several new compounds that, in early testing, promise to be both safer and more effective in fighting malaria and some forms of cancer than the current “gold standard” drug treatments.
Scientists will announce their successful results in late August at the American Chemical Society’s annual summer meeting, held this year in Philadelphia. Some of the results also appeared in the January 2004 issue of the Journal of Medicinal Chemistry. “Preliminary data show that our laboratory-synthesized compounds have a therapeutic index – the measure of a drug’s safety and efficacy – that is better, in some cases, many times better, in rodents than the drugs currently considered the gold standard for chemotherapy of both malaria and prostate cancer,” said Gary Posner, Scowe Professor of Chemistry in the Krieger School of Arts and Sciences at Johns Hopkins. “These results are preliminary, but exciting, and certainly worth pursuing.”
Malaria afflicts between 300 million and 500 million people a year, killing between 1.5 million and 3 million of them – mostly children. Spread by female mosquitos feeding on human blood, the most commonly fatal strain of the malaria parasite began showing formidable resistance to current treatments decades ago, making the development of new and more effective drugs a worldwide priority.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
