How do pulmonary tyrosine kinase inhibitors work?

Pulmonary tyrosine kinase inhibitors are medications used to treat progressive lung diseases such as pulmonary fibrosis which cause scarring and thickening of the lungs resulting in loss of lung function. Pulmonary tyrosine kinase inhibitors prevent scar tissue formation in the lungs by inhibiting the activity of tyrosine kinase.

Tyrosine kinases are enzymes that play a key role in intercellular communication and many cellular functions including regulation of cell growth, proliferation, differentiation, and survival. Tyrosine kinases respond to growth factor proteins and activate a downstream signaling cascade that initiates action within the cell.

In fibrotic lung diseases, tyrosine kinases promote abnormal growth of scar tissue which replaces normal lung tissue, progressively affecting lung function. Pulmonary tyrosine kinase inhibitors prevent tyrosine kinases from promoting scar tissue growth in the lungs.

Pulmonary tyrosine kinase inhibitors prevent the activity of many tyrosine kinases implicated in pulmonary fibrosis including:
