Berberine is an essential phytochemical for the treatment of various diseases; however, when used to treat osteoporosis, it has minor effect as compared with that of the currently available drugs. This study aimed to find a new compound that would have a better anti-osteoporotic effect than that of berberine. Based on structure and activity relationship study, we identified compound 2c, a berberine derivative, to be the most potent compound to affect osteoblast differentiation. Compound 2c was more effective than berberine and exhibited no toxicity within its effective concentration. Compound 2c increased, in a dose-dependent manner, ALP activity during osteoblast differentiation and enhanced the mRNA expression of osteogenic factors including ALP, Runx2, and Osterix. Furthermore, compound 2c increased the transcriptional activity induced by BMP4 on the ALP and BSP promoter. Taken together, compound 2c shows promise as a therapeutic agent for osteoporosis by promoting osteoblast differentiation. Copyright © 2020 Elsevier Inc. All rights reserved.
