In our effort towards the identification of novel BuChE-IDO1 dual-targeted inhibitor for the treatment of Alzheimer's disease (AD), sertaconazole was identified through a combination of structure-based virtual screening followed by MM-GBSA rescoring. Preliminary chemical optimization was performed to develop more potent and selective sertaconazole analogues. In consideration of the selectivity and the inhibitory activity against target proteins, compounds 5c and 5d were selected for the next study. Further modification of compound 5c led to the generation of compound 10g with notably improved selectivity towards BuChE versus AChE. The present study provided us with a good starting point to further design potent and selective BuChE-IDO1 inhibitors, which may benefit the treatment of late stage AD.

A novel process involving base-catalyzed intramolecular defluorination/O-arylation of readily available α-fluoro-β-one-sulfones was realized and provided a series of 3-fluoro-1,4-oxathiine 4,4-dioxide derivatives in good to excellent yields. Unlike traditional defluorination reactions with stoichiometric base as the deacid reagent, this process is triggered by a catalytic amount of base (TMG: tetramethylguanidine) and molecular sieves serve as both an adsorbent to remove HF acid and an activator to assist C-F bond cleavage.

Paragraph 0070-0072; 0106-0107, (2021/04/26)
The invention relates to the field of medicines, and particularly discloses a BuChE-IDO1 inhibitor as well as a preparation method and application thereof. The 7-chlorine-3-substituted benzothiophene part of sertaconazole is chemically modified, the influence of the 7-chlorine-3-substituted benzothiophene part of sertaconazole on the in-vitro inhibitory activity of AChE, BuChE and IDO1 is explored, the target compound is further optimized, and the technical problems that an existing BuChE-IDO1 inhibitor is poor in pertinence and safety are solved. What is explored is that an appropriate substituent group introduced to a 2-benzothiazole ring can form additional interaction with surrounding amino acids and heme iron, so that the binding affinity of the analogue with BuChE and IDO1 is increased, and a new idea is broadened for more efficient and targeted treatment of advanced AD diseases.
