Misfolded or unfolded proteins are accumulated in lumen of endoplasmic reticulum (ER) in ER stress condition. It has been implicated in many pathological conditions such as Alzheimer’s disease, diabetic retinopathy, atherosclerosis, β-cell apoptosis and lung inflammation. We found a series of N-substituted-2-arylcarbonylhydrazinecarbothioamides to potently decrease ER stress signal, showing up to almost 300-fold better activity than 1-hydroxynaphthoic acid and tauro-ursodesoxycholic acid, positive controls, respectively. Structure?activity relationship (SAR) study showed that 2-arylcarbonyl moiety is critical for the activity of the hydrazinecarbothioamide analogues and side chains tethering on thioamide moiety were relatively insensitive to the activity. Some analogues were found to consistently exert the potency under more physiologically relevant condition where ER stress was induced by palmitic acid. ER stress markers such as CHOP and phosphorylated eIF2α and PERK were accordingly decreased in western blotting upon treatment of compound 4h. Potential ER stress inhibitory activity and novel structures could provide a novel platform for new chemical chaperone and therapy for protein misfolding diseases.

A simple and convenient one-pot protocol for the synthesis of substituted 2-amino-1,3,4-oxadiazoles mediated by (tosylimino)phenyl-γ3- iodane has been described. Acylthiosemicarbazides prepared from the corresponding acylhydrazides undergo effi

A series of 1,2,4,5-tetrakis(1,2,4-triazolyl)benzenes and 1,2,4,5-tetrakis(1,3,4-oxadiazolyl)benzenes was synthesized by nucleophilic addition of sodium salts of 4-phenyl-2,4-dihydro-3H-1,2,4-triazole-3-thiones and 1,3,4-oxadiazole-2(3H)-thiones to 1,2,4,5-tetrakis(bromomethyl)benzene. The structure of the newly synthesized compounds was confirmed by elemental analysis, IR and 1H and 13C NMR spectra. Supplemental materials are available for this article.
