Description

Imatinib (Gleevec) is a number of tyrosine kinase enzymes specific inhibitor. It act by specifically inhibiting a certain enzyme that is characteristic of a particular cancer cell, rather than non-specifically inhibiting and killing all rapidly dividing cells, and served as a model for other targeted therapy modalities through tyrosine kinase inhibition. In chronic myelogenous leukemia, the Philadelphia chromosome leads to a fusion protein of abl with bcr (breakpoint cluster region), termed bcr-abl. As this is now a constitutively active tyrosine kinase, it is used to decrease bcr-abl activity. It is being used as an experimental agent to suppress platelet-derived growth factor (PDGF) by inhibiting its receptor (PDGF-Rβ).
