Abstract: We report herein our preliminary results of a SAR study of quinazoline-based inhibitors of p56lck and EGF-R tyrosine kinase activity. The most potent inhibitor of p56lck identified, RPR-108518A (10), has an IC50 of 0.50 μM. The 3-chlorophenoxy- and 3-chlorothiophenoxy- derivatives 5 and 6 were also shown to be extremely potent EGF-R inhibitors.
