A protein kinase inhibitor (PKI) is a type of enzyme inhibitor that blocks the action of one or more protein kinases. Protein kinases are enzymes that phosphorylate (add a phosphate, or PO4, group) to a protein and can modulate its function.
The phosphate groups are usually added to serine, threonine, or tyrosine amino acids on the protein. Most kinases act on both serine and threonine, the tyrosine kinases act on tyrosine, and a number (dual-specificity kinases) act on all three. There are also protein kinases that phosphorylate other amino acids, including histidine kinases that phosphorylate histidine residues.[citation needed]
Phosphorylation regulates many biological processes, and protein kinase inhibitors can be used to treat diseases due to hyperactive protein kinases (including mutant or overexpressed kinases in cancer) or to modulate cell functions to overcome other disease drivers.
Clinical use
editKinase inhibitors such as dasatinib are often used in the treatment of cancer and inflammation.[1]
Some of the kinase inhibitors used in treating cancer are inhibitors of tyrosine kinases.[2] The effectiveness of kinase inhibitors on various cancers can vary from patient to patient.[3]

Note:
AD = Approval date.
MS = Myelosuppression.
D = Diarrhoea.
FR = Fluid retention.
As far as myelosuppression, diarrhoea and fluid retention goes: +++ means >70% of patients exhibit clinically significant myelosuppression. ++ means 30-70% of patients exhibit significant myelosuppression. + means 10-30% of patients exhibit significant myelosuppression. - means 0-10% of patients exhibit this side effect.
General references templates are given, which refer the reader to the respective drug database.
