Researchers at the Technion-Israel Institute of Technology have developed a tiny "Trojan Horse" system for delivering cancer-fighting drugs, reports the American Technion Society. The researchers created the system by attaching folic acid and an anticancer drug to an extract from the coniferous Larix (Larch) tree. "We were looking for a natural polymer that would be highly soluble in water, and found it in a polysaccharide known as arabinogalactan, which is extracted from the Larix," explains lead researcher Yoav Livney. The system is expected to be especially efficient against ovarian, kidney and uterine cancer, which are characterized by high production of folic acid receptors. Report
