Нилотиниб

Описание

Chronic myeloid leukemia (CML), a hematological stem-cell disorder, is definitively diagnosed by the detection of the Philadelphia chromosome, a truncated version of chromosome 22 resulting from the reciprocal translocation of chromosomes 9 and 22 induced by a single mutagenic event. The consequence is the juxtaposition of two genes creating a fusion gene BCR-ABL. This gene leads to the translation of a fusion protein with increased tyrosine kinase activity that contributes to the pathogenesis of CML. Targeting the BCR-ABL protein has led to the successful intervention of the disease. Now established as first-line therapy for CML, imatinib was the first selective tyrosine kinase inhibitor of BCR-ABL. Since imatinib only binds to an inactive conformation of the ABL kinase portion, the conformational restrictions contribute to its selectivity.

Использование

Nilotinib, an orally active signal transduction inhibitor that selectively inhibits the tyrosine kinase Bcr-Abl, was discovered and developed by Norvartis and was launched for the treatment of chronic myeloid leukemia (CML) in patients with Philadelphia chromosome-positive (Ph+) disease who are resistant or intolerant to imatinib mesilate. Additional clinical trials are currently underway for the treatment of acute lymphoblastic leukemia (ALL) and gastrointestinal stromal tumors (GISTs).

Определение

ChEBI: Nilotinib is a member of (trifluoromethyl)benzenes, a member of pyrimidines, a member of pyridines, a member of imidazoles, a secondary amino compound and a secondary carboxamide. It has a role as an antineoplastic agent, a tyrosine kinase inhibitor and an anticoronaviral agent.
