Multi-target, 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 compounds were evaluated against epidermoid carcinoma (A431) and non-small cell lung cancer (A549 and H1975) cell lines, which displayed weak to potent anticancer activity. In particular, compound 8v emerged as the most potent derivative against mutant-type H1975 cells, which exhibited comparable activity to osimertinib. Importantly, 8v exhibited stronger anti-proliferative activity than osimertinib against H1975 cells under hypoxic condition. Kinase inhibition studies indicated that 8v showed excellent inhibitory effect on EGFRT790M enzyme, which was 41 times more effective than gefitinib and almost equal to osimertinib. Mechanism studies revealed that 8v exhibited remarkable CAIX inhibitory effect comparable to acetazolamide and significantly inhibited the expression of p-EGFR as well as its downstream p-AKT and p-ERK in H1975 cells. Notably, 8v was found to inhibit the expression of CAIX and its upstream HIF-1α in H1975 cells under hypoxic condition. Molecular docking was also performed to gain insights into the ligand-binding interactions of 8v inside EGFRWT, EGFRT790M and CAIX binding sites.

Adenosine triphosphate (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 potential EGFR inhibitors through incorporation of macrocyclic polyamine into 4-anilinoquinazoline scaffold. It is expected that anilinoquinazoline part effectively bind to EGFR domain, while ATP molecules are captured by a macrocyclic polyamine moiety. In vitro experiments exhibited that most of tested compounds suppressed tumor cell proliferation more strongly than Gefitinib and Lapatinib (dual inhibitor of EGFR/HER2) as controls. In kinase assays, the compound 1f showed excellent dual inhibition activity toward EGFRWT (IC50 = 1.4 nM) and HER2 (IC50 = 2.1 nM). In vivo pharmacology evaluation of 1f showed significant antitumor activity (TGI = 44.2%) in A549 xenografts mice. The current work provided a feasible solution to optimize anilinoquinazoline-based inhibitors.

4-Anilinoquinazoline analogues stand out among many kinds of small molecules that inhibit the tyrosine kinase activities of epidermal growth factor receptor (EGFR), thus serving as significant molecular targets for anticancer drug design. Herein, a series of novel perfluorocarbon (PFC) modulated 4-anilinoquinazolines were designed and prepared straightforwardly by nucleophilic substitution reaction of various anilinoquinazolines and PFC-derived methanesulfonate. In the presence of base, the reaction proceeded smoothly to afford a wide range of 4-anilinoquinazolines with different substituents on aniline moiety in good to high yields. Furthermore, the PFC-modified analogues of gefitinib and erlotinib were also obtained in 93% and 90% respectively, which may have potential for developing new inhibitors of the epidermal growth factor receptor (EGFR) tyrosine kinase and fluorinated contrast agents (CA) for 19F MRI.

A series of hybrids derived from 4-anilinoquinazoline and hydroxamic acid were designed, synthesized, and evaluated as dual inhibitors of vascular endothelia growth factor receptor-2 (VEGFR-2) tyrosine kinase and histone deacetylase (HDAC). Most of these compounds exhibited potent HDAC inhibition and moderate VEGFR-2 inhibition. Among them, compound 6l exhibited the most potent inhibitory activities against VEGFR-2 (IC50 = 84 nM) and HDAC (IC50 = 2.8 nM). It also showed the most potent antiproliferative ability against MCF-7, a human breast cancer line, with IC50 of 1.2 μM. Docking simulation supported the initial pharmacophoric hypothesis and suggested a common mode of interaction of compound 6l at the active binding sites of VEGFR-2 and HDAC.

A series of 4-anilinoquinazolines with C-C multiple bond substitutions at the 6-position were synthesized and investigated for their potential to inhibit epidermal growth factor receptor (EGFR) tyrosine kinase activity. Among the compounds synthesized, alkyne 6d and allenes 7d and 7f significantly inhibited EGFR tyrosine kinase activity. These compounds inhibited EGF-mediated phosphorylation of EGFR in A431 cells, resulting in cell-cycle arrest and apoptosis induction. The C-C multiple bonds substituted at the C-6 position of the anilinoquinazoline framework were essential for the significant inhibitory activity. Compounds with long carbon chains (n = 3-6), such as 6c-f, 7c-f, 11, and 12, displayed prolonged inhibitory activity.
