A substance that inhibits or prevents the action of kinase enzymes, which add phosphate groups to proteins in cellular processes.
From anti- (against) + kinase (from Greek kinein, to move + -ase, enzyme suffix). This biochemical term emerged as scientists studied cellular signaling and enzyme inhibition.
Cancer drugs often work as antikinases because cancer cells use kinase enzymes excessively to signal 'keep dividing!'—by blocking these enzymes, doctors can slow or stop the cancer's growth without harming normal cells as much.
