3BDO—A new autophagy inhibitor

MTOR, a central regulator of autophagy, is involved in cancer and cardiovascular and neurological diseases. Modulating the MTOR signaling balance could be of great significance for numerous diseases. In previous studies, Professor BaoXiang Zhao of Shandong University found a chemical small molecule , 3-Benzyl-5-((2-nitrophenoxy) methyl)–dihydrofuran-2(3H)-one (3BDO), that inhibited autophagy in human umbilical vein endothelial cells (HUVEC s) and neuronal cells. JK Scientific offers 3BDO as sole agent.

3BDO was more efficient than 3-MA as autophagy inhibitor

3BDO could dock on FKBP1A in the same sites (TYR82A and ILE56A) as Rapamycin

Trifluoromethylthiolating Reagents

The trifluoromethylthio group (CF3S-) represents one of the most lipophilic substituents. It is well known that incorporation of the trifluoromethylthio group into small molecules greatly enhances their ability to cross lipid membranes and their absorption rate in vivo. In addition, the high electronegativity of the CF3S group significantly improves the small molecule’s stability in acidic environments. Thus, the trifluoromethylthio group has drawn special attention from the pharmaceutical and agrochemical industries for its use in isosetere-based drug design.

J&K offers trifluoromethylthiolating reagents developed by Qilong Shen’s group at Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences. There are two types of these new electrophilic reagents: Trifluoromethanesulfenates (Lu-Shen reagent) and N-trifluoromethylthiosaccharin (Shen reagent).
