A tyrosine kinase inhibitor (TKI) is a pharmaceutical drug that inhibits tyrosine kinases. Tyrosine kinases are enzymes responsible for the activation of many proteins by signal transduction cascades. The proteins are activated by adding a phosphate group to the protein (phosphorylation), a step that TKIs inhibit. TKIs are typically used as ...
Intedanib is a multiple tyrosine kinase inhibitor and is the first drug to treat idiopathic pulmonary fibrosis. [4] Indol derivatives with 1-NH of 2-indolinone motif that is an H-bond donor, and 2-carbonyl oxygen that acts as an H-bond acceptor, bind with Glu915 and Cys917, respectively.
Cancer's response to an inhibitor of tyrosine kinase was assessed in a clinical trial. [15] In this case, Gefitinib is the inhibitor of tyrosine kinase. Incorrect tyrosine kinase function can lead to non-small cell lung cancer. [16]
Imatinib use may cause lightening/depigmentation or darkening/repigmentation of hair (as is the case with some other tyrosine kinase inhibitors) and/or skin as well as hyperpigmentation of the gingiva. The median onset of hair color change is 4 weeks after initiation of therapy (but may occur over a year after initiation), is dose-dependent ...
Axitinib, sold under the brand name Inlyta, is a small molecule tyrosine kinase inhibitor developed by Pfizer.It has been shown to significantly inhibit growth of breast cancer in animal models [4] and has shown partial responses in clinical trials with renal cell carcinoma (RCC) [5] and several other tumour types.
ALK inhibitors are anti-cancer drugs that act on tumours with variations of anaplastic lymphoma kinase (ALK) such as an EML4-ALK translocation. [1] They fall under the category of tyrosine kinase inhibitors , which work by inhibiting proteins involved in the abnormal growth of tumour cells.
Nilotinib is a selective Bcr-Abl kinase inhibitor. [13] [18] Nilotinib is 10-30 fold more potent than imatinib in inhibiting activity of the Bcr-Abl tyrosine kinase and proliferation of Bcr-Abl expressing cells. [12] [18] [20] [21] The drug effectively inhibits the auto phosphorylation of Bcr-Abl on Tyr-177 that is involved in CML pathogenesis ...
