Structure-activity and structure-property relationships of novel Nrf2 activators with a 1,2,4-oxadiazole core and their therapeutic effects on acetaminophen (APAP)-induced acute liver injury
The antioxidant function induced by Nrf2protects the liver from damage. We found a novel Nrf2 activator named compound 25 via structural modification of compound 1 we previously reported. In vitro, compound 25 induced Nrf2 transport into the nucleus and protected hepatocyte L02 cells from APAP-induced cytotoxicity via activating the Nrf2-ARE signalingpathway. In vivo, 25 exhibited therapeutic effects

We report herein a high-throughput methodology for the synthesis of 1,2,4-oxadiazole and 1,2,4-triazole small-molecule libraries using an integrated synthesis and purification platform.
The new pyridine, 4‐pyridine N‐oxide and pyrazine derivatives exhibiting an antibacterial activity have been synthesized. Amidoximes were transformed into N‐hydroxyimidoyl chlorides and then into appropriate oximes. Upon treatment of pyridinecaboxamidoximes with methyl iodide 1‐methylpyridynium iodides were formed. Reaction of amidoximes with various carbamoyl chlorides led to corresponding 5‐aminocarbonyl‐1
