Design, synthesis and biological evaluation of quinazoline–phosphoramidate mustard conjugates as anticancer drugs
摘要:
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 IC50 of 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). (C) 2017 Elsevier Masson SAS. All rights reserved.

The present invention has disclosed a compound of formula I and a pharmaceutically acceptable salt or a solvate thereof, wherein the substituents are as defined in the description. The invention has also disclosed a method for preparing the compound of formula I, the pharmaceutical compositions comprising the same and their uses in the preparation of an anti-tumor medicament.
especially dual-target, drug design has become a popular research field for cancer treatment. Development of small molecule dual-target inhibitors through hybridization strategy can provide highly potent and selective anticancer agents. In this study, three series of quinazoline derivatives bearing a benzene-sulfonamide moiety were designed and synthesized as dual EGFR/CAIX inhibitors. All the synthesized
(ATP)-competitive inhibitors of the epidermal growth factor receptor (EGFR) have provided a significant improvement in the disease outcome of nonsmall cell lung cancer (NSCLC). Unfortunately, some marketed drugs affect a transient beneficial response in EGFR mutant NSCLC patients. We reported a series of potentialEGFRinhibitorsthroughincorporation of macrocyclic polyamine into 4-anilinoquinazoline scaffold
