  Thirty quaternary coptisine derivatives from a synthesized library were found to activate the in vitro transcription of x-box-binding protein 1 (XBP1). Among these, the dihydrocoptisines were demonstrated by in vitro XBP1 transcriptional activity assays and animal experiments to be much more active anti-ulcerative colitis (UC) agents than quaternary coptisines, tetrahydrocoptisines, and the positive control. Unsubstituted dihydrocoptisine exhibited more significant anti-UC efficacy than dihydrocoptisines substituted at the C-8 or C-13 position. The EC50 value of dihydrocoptisine for XBP1 transcriptional activation was 2.25 nM. Dihydrocoptisine exhibited a significant dose effect relationship, as indicated by biomarkers in in vitro and in vivo experiments. According to this study, the starting material's reductive states and the substitution patterns of the dihydrocoptisines were determined to be the critical parameters for modulating their anti-UC efficacy, and the dihydrocoptisine skeleton was designated as the key pharmacophore. The synthesized dihydrocoptisine is a promising lead for developing anti-UC drugs.

  New and convenient synthesis of 2,3,9,10-tetraoxygenated protoberberine alkaloids and their 13-methyl alkaloids through the same intermediates was developed. Acylation of the brominated benzylphenethylamine (13) with alpha-chloro-alpha-(methylthio)acetyl chloride, followed by cyclization with stannic chloride, furnished the key intermediates 4-methylthio-3-phenethylisoquinolin-3-ones (14), which were
