Salts of kukoamine B, their preparation method and their pharmaceutical use in preparation of drugs for preventing and treating sepsis. Experiments indicate that salts of kukoamine B have a good effect on antagonizing the key factors inducing sepsis, and can be used in the preparation of drugs for preventing and treating sepsis. Under the current circumstances of the lack of effective measures for the treatment of sepsis in clinical practice, the medicinal formulations, which comprise the salts of kukoamine B, pharmaceutically acceptable carrier and/or diluent, provide a new approach for the prevention and treatment of sepsis.

Salicylicacid is an NSAID with serious side effects on the GIS. The side effects of salicylicacid on the GIS are slightly reduced by acetylating salicylicacid. 12 new ester analogs of salicylicacid were synthesized with high yields in this study. The chemical structures of the synthesized compounds were characterized by 1H-NMR, 13C-NMR, and HRMS spectra. The inhibitory potential of the compounds
