Acid-seeking 'warheads' promise safer, more effective cancer weapons

Researchers in California report development of an anti-cancer “warhead” that targets the acidic signature of tumor cells in much the same way that heat-seeking missiles seek and destroy military targets that emit heat. These acid-seeking substances are not toxic to healthy cells, and represent a new class of potentially safer, more effective anti-cancer drugs, they say. Their study is scheduled for the March 6 issue of ACS’ The Journal of Physical Chemistry B.
