Ecstasy is known to kill some cancer cells, but scientists have increased its effectiveness 100-fold, they said in Investigational New Drugs journal.
Their early study showed all leukaemia, lymphoma and myeloma cells could be killed in a test tube, but any treatment would be a decade away. [...]
In 2006, a research team at the University of Birmingham showed that ecstasy and anti-depressants such as Prozac had the potential to stop cancers growing.
The problem was that it needed doses so high they would have been fatal if given to people.
The researchers, in collaboration with the University of Western Australia, have chemically re-engineered ecstasy by taking some atoms away and putting new ones in their place.

The results of Geoffrey von Maltzahn et al. in their Nature Materials publication reveal that nanoparticles that communicate with each other can deliver more than 40-fold higher doses of chemotherapeutics (anti-cancer drugs) to tumors than nanoparticles that do not communicate can deliver. These results show the potential for nanoparticle communication to amplify drug delivery over that achievable by nanoparticles that work alone, similar to how insect swarms perform better as a group than the individual insects do on their own.

Then, for three weeks, researchers injected standard doses of THC into mice that had been implanted with human lung cancer cells, and found that tumors were reduced in size and weight by about 50 percent in treated animals compared to a control group. There was also about a 60 percent reduction in cancer lesions on the lungs in these mice as well as a significant reduction in protein markers associated with cancer progression, Preet says.
Although the researchers do not know why THC inhibits tumor growth, they say the substance could be activating molecules that arrest the cell cycle. They speculate that THC may also interfere with angiogenesis and vascularization, which promotes cancer growth.
Preet says much work is needed to clarify the pathway by which THC functions, and cautions that some animal studies have shown that THC can stimulate some cancers. “THC offers some promise, but we have a long way to go before we know what its potential is,” she said.
