These are Wyeth’s EKB569 analogs which are covalent inhibitors of EGF.
There’s a cystine residue in proximity which adds 1,4 to the butenamide.

There should indeed be a methylene and I’ll fix that if I haven’t already by the time you read this. Pfizer’s got one of these kinds of things in the clinic too, named Canertinib (sans amine). Here’s a free link to a relevant article:

    Either the structure or the patents you refer to is wrong. The scaffold is based on a 3 cyanoquinolines, NOT a quinazolinescaffold as in your picture. Just to be correct! =)

    –Updated–Thanks for the correction – boy I made a mess of this one.
