摘 要:Objective:Hepatotoxicity of traditional Chinese medicines(TCMs) has attracted worldwide concerns;however,data on TCM toxicity are *** major reason lies in that safety evaluation in vitro assays is much costly and time-consuming based on the numerous ingredients in varities of *** study aims to develop a more applicable and optimal tool to evaluate TCM ***:A quantitative structure-activity relationship(QSAR) analysis was performed based on published data and *** and Drug Administration’s Liver Toxicity Knowledge Base(LTKB).Results:Eleven herbal ingredients with proven liver toxicity in the literature were added into the dataset besides chemicals from *** generated QSAR model yielded a sensitivity of 83.8%,a specificity of 70.1% and an accuracy of 80.2%.As a comparison,using the same procedure,another QSAR model was built up on the basis of the identical compounds excluding the 11 herbal *** performance of the two QSAR models was further assessed by the external independent *** the externally tested 20 compounds from TCMs,14 hepatotoxins were all accurately predicted by the QSAR model generated from the dataset containing herbal ingredients;while 4 well-known hepatotoxins were not correctly predicted by the QSAR model generated from the dataset excluding herbal ***:Adding natural hepatotoxins into the dataset makes the QSAR model more applicable for TCM hepatotoxicity assessment,which provides a right direction in the methodology study for TCM safety *** generated QSAR model has the practical value to prioritize the hepatotoxicity risk of TCM compounds.
