A protein kinase inhibitor is a kind of enzyme inhibitor that blocks the motion of a number of protein kinases. Protein kinases are enzymes that add a phosphate (PO4) group to a protein, and might modulate its perform.
The phosphate teams are often added to serine, threonine, or tyrosine amino acids on the protein: most kinases act on each serine and threonine, the tyrosine kinases act on tyrosine, and a quantity (dual-specificity kinases) act on all three. There are additionally protein kinases that phosphorylate different amino acids, together with histidine kinases that phosphorylate histidine residues.[citation needed]
Phosphorylation regulates many organic processes, and protein kinase inhibitors can be utilized to deal with illnesses attributable to hyperactive protein kinases (together with mutant or overexpressed kinases in most cancers) or to modulate cell features to beat different illness drivers.

Scientific use[edit]
Kinase inhibitors akin to dasatinib are sometimes used within the remedy of most cancers and irritation.[1][2]
A number of the kinase inhibitors utilized in treating most cancers are inhibitors of tyrosine kinases.[3]
The effectiveness of kinase inhibitors on numerous cancers can differ from affected person to affected person.[4]
Examples[edit]
There are a number of medication launched or in improvement that concentrate on protein kinases and the receptors that activate them:
Comparability of obtainable brokers[edit]
Word:
AD = Approval date.
MS = Myelosuppression.
D = Diarrhoea.
FR = Fluid retention.
So far as myelosuppression, diarrhoea and fluid retention goes: +++ means >70% of sufferers exhibit clinically vital myelosuppression. ++ means 30-70% of sufferers exhibit vital myelosuppression. + means 10-30% of sufferers exhibit vital myelosuppression. – means 0-10% of sufferers exhibit this facet impact.
