Definition: A protein kinase inhibitor is a type of enzyme inhibitor that blocks the action of one or more protein kinases. Protein kinases are enzymes that add a phosphate (PO4) group to a protein, and can modulate its function.

Protein-kinase inhibitors are generally small molecules that show competitive inhibition with respect to ATP.

Examples

- tyrosine kinase inhibitors (TKIs )
