: SET protein is a multi-functional oncoprotein that is ubiquitously expressed in most tumor cells. Dysregulation of SET has been associated with many types of cancer. Due to ever-accumulating evidence of its strong correlation with both poor prognosis and drug resistance, the targeting of SET is starting to be explored. SET is currently regarded as a potential target for cancer therapy, and several inhibitors are being developed for clinical trials. In this review, the physiological and pathological functions of SET, as well as its antagonists, will be discussed along with the prospects and challenges involved with translating SET inhibitors into bona fide therapeutic options.

The selective O-benzylation of 2-oxo-1,2-dihydropyridines plays a critical role in organic synthesis of natural products and biological active molecules. Herein we report a novel ternary system of ZnO, ZnCl2 and N,N-diisopropylethylamine (DIEA), that is highly effective for selective O-benzylation of 2-oxo-1,2-dihydropyridines using abundant substituted benzyl halides and related substituted 2-oxo-1,2-dihydropyridines compounds. This process allows access to a variety of O-benzyl products under mild reaction conditions, which are important synthetic intermediates in the protection of functional groups, and represents a new method toward the development for the O-benzylation of 2-oxo-1,2-dihydropyridines.

A synthetic route to 3-formylbenzenesulfonyl chloride derivatives from the corresponding benzaldehydes has been developed. The key step in this procedure is the conversion of aldehyde bisulfite adducts to target compounds via a two-stage reaction in the presence of Na2SO4. A series of 3-formylbenzenesulfonyl chloride derivatives were prepared by this method and identified by chemical derivatization method.

There are many protocols for the preparation of hydroxamic acids from their corresponding carboxylic esters or carboxylic acids, but as for ester precursors, strong bases are usually indispensable. Herein, an...

Two series of L-quebrachitol derivatives have been designed and synthesized in order to search for novel hypoglycemic agents. The α-glycosidase inhibitory activities of these compounds were evaluated, and their structure-activity...
