Mr. Myers et al., THE PREPARATION AND SAR OF 4-(ANILINO), 4-(PHENOXY), AND 4-(THIOPHENOXY)-QUINAZOLINES - INHIBITORS OF P56(LCK) AND EGF-R TYROSINE KINASE-ACTIVITY, Bioorganic & medicinal chemistry letters, 7(4), 1997, pp. 417-420
We report herein our preliminary results of a SAR study of quinazoline
-based inhibitors of p56(lck) and EGF-R tyrosine kinase activity.(1) T
he most potent inhibitor of p56(lck) identified, RPR-108518A (10), has
an IC50 of 0.50 mu M. The 3-chlorophenoxy- and 3-chlorothiophenoxy- d
erivatives 5 and 6 were also shown to be extremely potent EGF-R inhibi
