5-Substituted 4-anilinoquinazolines as potent, selective and orally active inhibitors of erbB2 receptor tyrosine kinase.

ABSTRACT

Starting from a 6,7-substituted quinazoline lead 4, optimisation of 5-substituted quinazolines containing an extended aniline motif led to potent and selective inhibitors of erbB2 receptor tyrosine kinase, and a representative compound 12a inhibited tumour growth in a mouse xenograft model.
