ABSTRACT
OBJECTIVE To investigate the material basis and action mechanism for preventing osteoporosis of Erzhi Pill through network pharmacology. METHODS Autodock 4.0 was used to establish the interactions of compounds from Erzhi Pill with 36 target proteins related to OP, and the “ingredient-target-pathway” network of Erzhi Pill for OP treatment was constructed and analyzed by Cytoscape3.6.0. RESULTS 21 ingredients of Erzhi Pill were found to dock with 35 target proteins(POR,CYP17A1,PTH, et al) and 15 pathways, such as HIF-1 signaling pathway, Rheumatoid arthritis and Thyroid hormone signaling pathway, were affected. CONCLUSION The mechanism of Erzhi Pill for OP treatment may be linked with regulating metabolism pathways, intervening related diseases,adjusting the level of estrogen, and so on, reflecting the action features of multi-ingredients, multi-targets and multi-pathways of traditional Chinese medicine.This study provides new clues for further basic study on the pharmacological mechanism of Erzhi Pill.
