Abstract:
Background: Herba Epimedii, a commonly used traditional herb, has been proven
effective in ameliorating osteoporosis. However, the active ingredients and potential mechanism
need further exploration.
Objective: To screen active ingredients of Herba Epimedii with the effect of ameliorating osteoporosis
and to explore their potential mechanisms.
Methods: TCMSP and Swiss Target Prediction were applied to collect the ingredients of Herba
Epimedii and their targets. UniProt, GeneCards, TTD, DisGeNET, and OMIM were adopted to
search osteoporosis-related genes. STRING and DAVID were used to perform enrichment analysis.
Effects of screened ingredients were evaluated on MC3T3-E1 cells and RAW264.7 cells,
respectively.
Results: Eleven ingredients were screened by Network Pharmacology. They exerted a promoting
effect on MC3T3-E1 cells (10-9-10-5 M). The ingredients didn’t significantly affect ALP activity
and osteoblastogenesis-related genes. Baohuoside 1, Sagittatoside B, Chlorogenic acid,
Cryptochlorogenic acid, and Neochlorogenic acid significantly increased calcium depositions.
The ingredients didn’t exhibit a dose-dependent inhibition or promotion on RAW264.7 cells.
Baohuoside 1, Sagittatoside B, Neochlorogenic acid, Cryptochlorogenic acid, Icariin, Epimedin
A, Chlorogenic acid, Sagittatoside A, and Epimedin C suppressed the level of TRACP. Baohuoside
1, Sagittatoside B, Cryptochlorogenic acid, Neochlorogenic acid, Chlorogenic acid, Sagittatoside
A, and Icariin decreased the number of multinucleated osteoclastic cells. Baohuoside 1,
Sagittatoside B, and Cryptochlorogenic acid could significantly inhibit MMP-9 expression.
Conclusion: Neochlorogenic acid, Sagittatoside B, Chlorogenic acid, and Cryptochlorogenic acid
promoted MC3T3-E1 differentiation, among which Neochlorogenic acid showed significant
promotion in viability, mineralization, and OPN expression. Baohuoside 1, Sagittatoside B,
Cryptochlorogenic acid, Neochlorogenic acid, Chlorogenic acid, and Icariin inhibited
RAW264.7 differentiation, among which Baohuoside 1 showed significant inhibition on
TRACP, multinucleated osteoclastic cells number and MPP-9 expression. The mechanism might
relate to the FoxO signaling pathway, MAPK signaling pathway, and TNF signaling pathway.
