The Food and Drug Administration (FDA) has approved several quinazoline derivatives for clinical use as anticancer drugs. These include gefitinib, erlotinib, lapatinib, afatinib, and vandetanib (Fig.1) [43]. Gefitinib (Iressa®) was approved by the FDA in 2003 for the treatment of locally advanced or metastatic non-small-cell lung cancer (NSCLC) in patients after failure of both platinum-based and/or docetaxel chemotherapies. In 2004, erlotinib (Tarceva®) was approved by the FDA for treating NSCLC. Furthermore, in 2005, the FDA approved erlotinib in combination with gemcitabine for treatment of locally advanced, unrespectable, or metastatic pancreatic cancer. Erlotinib acts as a reversible tyrosine kinase inhibitor. Lapatinib (Tykreb®) was approved by the FDA in 2012 for breast cancer treatment. It inhibits the activity of both human epidermal growth factor receptor-2 (HER2/neu) and epidermal growth factor receptor (EGFR) pathways. Vandetanib (Caprelsa®) was approved by the FDA in 2011 for the treatment of metastatic medullary thyroid cancer. It acts as a kinase inhibitor of a number of cell receptors, mainly the vascular endothelial growth factor receptor (VEGFR), EGFR, and rearranged during transfection (RET)-tyrosine kinase (TK). Afatinib (Gilotrif®) was approved by the FDA in 2013 for NSCLC treatment. It acts as an irreversible covalent inhibitor of the receptor tyrosine kinases (RTK) for EGFR and erbB-2 (HER2).

An insight into the therapeutic potential of quinazoline derivatives as anticancer agents

Abstract

Cancer is one of the major causes of worldwide human mortality. A wide range of cytotoxic drugs are available on the market, and several compounds are in different phases of clinical trials. Many studies suggest that these cytotoxic molecules are also associated with different types of adverse side effects; therefore researchers around the globe are involved in the development of more efficient and safer anticancer drugs. In recent years, quinazoline and its derivatives have been considered as a novel class of cancer chemotherapeutic agents that show promising activity against different tumors. The aim of this article is to comprehensively review and highlight the recent developments concerning the anticancer activity of quinazoline derivatives as well as offer perspectives on the development of novel quinazoline derivatives as anticancer agents in the near future.
