By introducing various aromatic groups in 13-C of berberine and berberrubine, a series of 13-(substituted benzyl) berberine and berberrubine derivatives were synthesized and examined for antifungal activities against various human pathogenic fungi. The synthesized compounds exhibited more potent antifungal activities than berberine and berberrubine. Among them, 13-(4-isopropyl benzyl) berberine (6e) exerted the most potent antifungal activities against Candida species (MIC=1-8 microg/ml) and a 4-fold stronger activity than 13-(4-isopropyl benzyl) berberrubine (7e) synthesized by pyrolysis of compound 6e.

D001230 Aspergillus A genus of mitosporic fungi containing about 100 species and eleven different teleomorphs in the family Trichocomaceae.
D001599 Berberine An alkaloid from Hydrastis canadensis L., Berberidaceae. It is also found in many other plants. It is relatively toxic parenterally, but has been used orally for various parasitic and fungal infections and as antidiarrheal. Umbellatine
