An experimental drug derived from a poisonous weed can travel harmlessly through the bloodstream until it detects cancer cells and kills them. In laboratory studies, the researchers say, a three-day course of the drug G202 shrunk human prostate tumors grown in mice by an average of 50 percent within 30 days. It far outperformed docetaxel, a chemotherapy drug now used against prostate cancer, and was also highly effective against animal models of human breast cancer, kidney cancer, and bladder cancer.
