A series of novel quinazoline derivatives bearing various C-6 benzamide substituents were synthesized and evaluated as EGFR inhibitors, and most showed significant inhibitory potency against EGFR kinase. In particular, compound 6g possessed potent inhibitory activity against EGFR wild-type (IC = 5 nM), and strong antiproliferative activity against HCC827 and Ba/F3 (L858R) cell lines. Kinase profiling against a panel of 365 kinases showed that 6g was highly selective for EGFR. Furthermore, 6g showed desirable properties in assays of liver microsome metabolic stability and cytochromes P450 inhibition and preliminary pharmacokinetic study. The overall attractive profile of 6g made it an interesting compound for further development.

A novel mechanism for -heteroaryl C-H functionalization via dearomative addition-hydrogen autotransfer is described. Upon exposure to the catalyst derived from RuHCl(CO)(PPh) and Xantphos, dienes - suffer hydroruthenation to form allylruthenium nucleophiles that engage in -heteroaryl addition-β-hydride elimination to furnish branched products of C-C coupling - and -. Oxidative cleavage of isoprene adducts , , , and followed by ruthenium-catalyzed dynamic kinetic asymmetric ketone reduction provides enantiomerically enriched -heteroarylethyl alcohols - and, therefrom, -heteroarylethyl amines -.

Among the various cations, the Fe ion is one of the most critical transition metal ions in living cells for many cellular functions and enzymatic activities. The decrease or overloading of Fe can lead to different disruptions in humans. Also, Fe, highly toxic, is very common in all industrial wastewater.

Bromodomain-containing protein 4 (BRD4) has been identified as a promising target in drug discovery, and the development of novel specific BRD4 bromodomain inhibitors will benefit anti-inflammatory drug discovery as well as bromodomain function role disclose. Herein, inspired by marine quinazolinone alkaloid penipanoid C, we designed and synthesized a series of quinazolin-4(3H)-ones with diverse linkers between two aromatic ring systems. Among them, compound 25 possessed good in vitro BRD4 inhibitory activities (IC = 3.

Cancer, characterized by uncontrolled growth and spread of abnormal cells potentially influencing almost all tissues in the body, is one of the most devastating and lethal diseases throughout the world. Chemotherapy is one of the principal approaches for cancer treatment, but multidrug resistance and severe side effects represent the main barriers to the success of therapy, creating a vital need to develop novel chemotherapeutic agents. The 1,2,3-triazole moiety can be conveniently constructed by "click chemistry" and could exert diverse noncovalent interactions with various enzymes in cancer cells.
