HOW DO HEMATOLOGIC KINASE INHIBITORS WORK?

Kinase inhibitors also known as tyrosine kinase inhibitors (TKIs) are potent anticancer drugs. They disrupt the signal transduction pathways of enzyme tyrosine kinases which are involved in cell growth, migration, differentiation, apoptosis, and cell death. These drugs are used for the treatment of patients with intermediate- or high-risk myelofibrosis (MF).

The JAK-STAT (Janus-associated kinase-signal transducer and activator of transcription) pathway plays a key role in the signaling of several cytokines and growth factors and is involved in cellular proliferation, growth, hematopoiesis, and the immune response. JAK kinase levels may be increased in inflammatory diseases, myeloproliferative disorders, and various malignancies.

Fedratinib acts as a competitive inhibitor of protein tyrosine kinase including JAK-2 and other related kinases: FLT3, CD135, STK1, FLK2, and RET. Fedratinib inhibits and blocks the cellular signaling (JAK-STAT), and thus, the proliferation of the tumor cells is suppressed and apoptosis (programmed cell death) may be induced.

Ruxolitinib specifically binds and inhibits protein tyrosine kinases JAK-1 and 2, thus reducing inflammation and inhibiting cellular proliferation.
