Microwave-assisted three component one-pot synthesis of pyrimido-oxazepines
摘要:
A synthetic approach toward pyrimido-oxazepine analogs was developed through the use of microwave heating. Certain analogs can be made in one step, which make this a valuable tool in the investigation of this therapeutically relevant scaffold. (c) 2007 Elsevier Ltd. All rights reserved.
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.
