BICYCLIC COMPOUNDS CAPABLE OF INHIBITING TYROSINE KINASES OFTHE EPIDERMAL GROWTH FACTOR RECEPTOR FAMILY

摘要

Epidermal growth factor inhibitors of formula (1), where: at least one, and as many as three of A-E are nitrogen, with the remaining atom(s) carbon, or any two contiguous positions in A-E taken together can be a single heteroatom, N, O or S, in which case one of the two remaining atoms must be carbon, and the other can be either carbon or nitrogen; X = O, S, NH or NR7, such that R7 = lower alkyl (1-4 carbon atoms), OH, NH2, lower alkoxy (1-4 carbon atoms) or lower monoalkylamino (1-4 carbon atoms); n = 0, 1, 2.
