Quinazoline derivatives as anticancer drugs: a patent review (2011 -- present)

Introduction: Quinazoline is one of the most studied moieties in medicinal chemistry due to the wide range of biological properties such as the anticancer, antibacterial, anti-inflammatory, antimalarial and antihypertensive activities. During the past decades, several patents and articles have been published in international peer-reviewed literature regarding the discovery and development of original and promising quinazoline derivatives for cancer treatment. Although quinazolines are well known to inhibit EGFR, there is also a large panel of other therapeutic protein targets.Areas covered: This review summarized the new patents and articles published about quinazoline derivatives as anticancer drugs since 2011.Expert opinion: Since 2011, a lot of quinazoline compounds have shown EGFR inhibition. Unlike the first-generation EGFR inhibitors, they inhibit both wild-type and mutated EGFR. In recent years, a number of studies on quinazoline synthesis have been reported and used by several medicinal chemistry ...
