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.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics
Recently, researchers from Harvard and MIT succeeded in trapping a record 53 atoms and individually controlling their quantum state, realizing what is called a...
The historic first detection of gravitational waves from colliding black holes far outside our galaxy opened a new window to understanding the universe. A...
A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
