Product Code : AKI-AC-702
Product Desciption :
Erlotinib is an epidermal growth factor receptor/human epidermal growth factor receptor type 1 tyrosine kinas inhibitor. Erlotinib tablet potently inhibits the intracellular phosphorylation of EGFR. EGFR is expressed on the cell surface of normal cells and cancer cells.
The potent effectiveness of Erlotinib in blocking EGFR-mediated signalling in these EGFR mutation positive tumours is attributed to the tight binding of Erlotinib to the ATP-binding site in the mutated kinas domain of the EGFR.
Due to the blocking of downstream-signalling, the proliferation of cells is stopped, and cell death is induced through the intrinsic apoptotic pathway.
Tumour regression is observed in mouse models of enforced expression of these EGFR activating mutations.
