The present invention relates to thienopyrmidine compounds of formula (I) (one of A 1 and A 2 is S and the other is CH), salts thereof, as well as use and preparation of the same. These compounds are inhibitors of various protein tyrosine kinases (PTKs) of the ErbB family and consequently are useful in the treatment of disorders mediated by aberrant activity of such kinases. |
