  Tetracyclic tetrahydroprotoberberines (THPB) alkaloids contain an isoquinoline backbone and was endowed with various biological properties such as analgesic,anti-convulsant,anti-depressant and anti-psychotic abilities in the central nervous system.Despite the rapid progress of science,the treatment of infectious diseases still remains a serious problem to the scientific community.A key intermediate containing an aldehyde group at 12-position of tetrahydroprotoberberrubine was developed for future modification.This aldehyde is easy to be attacked by neucleophilic reagents to access a series of berberrubine modified benzimidazole derivatives that can ameliorate the weakness of berberine.
