Soluble 2-substituted aminopyrido [2, 3-d] pyrimidin-7-yl ureas. Structure-activity relationships against selected tyrosine kinases and exploration of in vitro and in vivo …
In continuing our search for medicinal agents to treat proliferative diseases, we have discovered 2-substituted aminopyrido [2, 3-d] pyrimidin-7-yl ureas as a novel class of soluble, potent, broadly active tyrosine kinase (TK) inhibitors. An efficient route was developed that enabled the synthesis of a wide variety of analogues with substitution on several positions of the template. From the lead structure 1, several series of analogues ...
