To enhance the potency of "combi-molecules", we designed 6a-d and 18 to release an inhibitor of EGFR TK and a bifunctional alkylator. The combi-molecules blocked EGFR TK with potency increasing with the basicity of the mustard moiety. They selectively killed cells transfected with EGFR and were potent against the DU145 prostate cancer cells. Combi-molecule 6a blocked EGFR phosphorylation in an irreversible manner, induced DNA-cross-links, and arrested the cells in mid-S.
