Tricyclic azepine derivatives: Pyrimido[4,5-b]-1,4-benzoxazepines as a novel class of epidermal growth factor receptor kinase inhibitors
摘要:
A novel class of pyrimido[4,5-b]-1,4-benzoxazepines is described as inhibitors of epidermal growth factor receptor (EGFR) tyrosine kinase. Two compounds display potent EGFR inhibitory activity of less than 1 mu M in cellular phosphorylation assays (IC50 0.47-0.69 mu M) and are highly selective against a small kinase panel. Such compounds demonstrate anti-EGFR activity within a class that is different from any known EGFR inhibitor scaffolds. They also provide a basis for the design of kinase inhibitors with the desired selectivity profile. (C) 2005 Elsevier Ltd. All rights reserved.
Novel tricyclic azepine derivatives: Biological evaluation of pyrimido[4,5-b]-1,4-benzoxazepines, thiazepines, and diazepines as inhibitors of the epidermal growth factor receptor tyrosine kinase
摘要:
Novel tricyclic derivatives containing an oxazepine, thiazepine, or diazepine ring were studied for their EGFR tyrosine kinase inhibitory activity. While the oxazepines were in general more potent than thiazepines, the diazepines displayed somewhat different structure-activity relationships. Moreover, the diazepines, in contrast to the oxazepines, showed appreciable inhibitory activity against the KDR tyrosine kinase. Furthermore, both oxazepines and diazepines demonstrated significant ability to inhibit autophosphorylation of EGFR in DiFi cells (generally, IC50 values in the single-digit micromolar to submicromolar range).
