  Synthesis and anti-endoplasmic reticulum stress activity of N-substituted-2-arylcarbonylhydrazinecarbothioamides

  摘要：

  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, beta-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 eIF2 alpha 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.

  4‐triazole‐5(4H)‐thione hybrids 6a – 6o was designed, synthesized and evaluated for their in vitro antibacterial activities against a panel of clinically important drug‐sensitive and drug‐resistant Gram‐positive and Gram‐negative pathogens. Our results revealed that all hybrids 6a – 6o had great potency against the tested strains, especially Gram‐negative pathogens. The synthesized hybrids were more potent

  Two classes of compounds, thiocarbamates 1 and triazoles 2, have been identified as HIV RT RNase H inhibitors using a novel FRET-based HTS assay. The potent analogs in each series exhibited selectivity and were active in cell-based assays. In addition, saturable, 1: 1 stoichiometric binding to target was established and time of addition studies were consistent with inhibition of RT-mediated HIV replication. (C) 2009 Elsevier Ltd.
