A series of novel compounds with phosphoramide mustard functionality incorporated into the quinazoline scaffold of EGFR/HER2 inhibitors were designed and synthesized as multi-target-directed ligands against tumor cells. In?vitro assays showed that tumor cell lines with high HER2 level were more sensitive to the compounds than tumor cells with low HER2 level. Compound 10d (EMB-3) was one of the most potent inhibitors with IC50of 7.4?nM and 82?nM against EGFR and HER2, respectively. The mechanism studies were also supported by the effect of 10d-induced DNA damage in MDA-MB-468?cells. In?vivo efficacy study showed that 10d could significantly inhibit H522 tumor xenograft model with a TGI of 68% at dose of 100?mg/kg (QDx28, p.o.) and no significant body weight loss was observed. MTD study indicated that compound 10d had no acute toxicity to mice at doses up to 900?mg/kg (single dose).

On the basis of combination strategy, a novel series of EGFR inhibitors were designed and synthesized by combination of dithiocarbamic acid esters and 4-anilinoquinazolines. The effect of the synthesized compounds on cell proliferation was evaluated by MTT assay in three human cancer cell lines: MDA-MB-468, SK-BR-3 and HCT-116. Two compounds (11d and 11f) were found more potent against all three cell lines and five compounds (11a, 11d-11g) were found more potent against both MDA-MB-468 and SK-BR-3 than Lapatinib. SAR studies revealed that the substituents on C6 and C7 positions of quinazoline, the amine component of dithiocarbamate moiety and the linker greatly affected the activity. This work provides a promising new strategy for the preparation of potent tyrosine kinase inhibitors.
