erlotinib is an approved drug (FDA (2004), EMA (2005))
Compound class: Synthetic organic
Comment: Erlotinib is a clinically approved type-1 inhibitor of the epidermal growth factor receptor (EGFR) receptor tyrosine kinase. This drug shows some selectivity for EGFR exon 19 deletion or exon 21 L858R mutations over the wild type receptor.
Subsequent studies have shown erlotinib to be a potent inhibitor of JAK2V617F activity. JAK2V617F, a mutant from of tyrosine kinase JAK2, is found in most patients with polycythemia vera (PV) and a substantial proportion of patients with idiopathic myelofibrosis or essential thrombocythemia. Study suggests that erlotinib may be used for treatment of JAK2V617F-positive PV and other myeloproliferative disorders. Specificity of inhibition with regard to other tyrosine kinase receptors remains to be fully characterized. Erlotinib is a Type-1 kinase inhibitor.
