Definition:A cyclic ether that is 16,17-dihydro-2H-8,4-(metheno)pyrazolo[4,3-h][2,5,11]benzoxadiazacyclotetradecin-15(10H)-one substituted by methyl groups at positions 2 and 10R, and by cyano, amino and fluoro groups at positions 3, 7 and 12 respectively. It is a small molecule inhibitor of ALK and ROS1 kinase developed by Pfizer for the treatment of ALK-positive non-small cell lung cancer.
