    Abstract: The present invention pertains to the field of toxicological assessments for risk stratification of chemical compounds. Specifically, it relates to a method for diagnosing liver toxicity. It also relates to a method of determining whether a compound is capable of inducing such liver toxicity in a subject and to a method of identifying a drug for treating liver toxicity. Furthermore, the present invention relates to a data collection comprising characteristic values of at least five metabolites, a data storage medium comprising said data collection, and a system and a device for diagnosing liver toxicity. Finally, the present invention- pertains to the use of a group of metabolites or means for the determination thereof for the manufacture of a diagnostic device or composition for diagnosing liver toxicity in a subject. For each sex, a different metabolome pattern, i.e. a different set of analytes is disclosed. The liver toxicity markers are mainly selected from free fatty acids, but also include various phosphatidylcholines, Hydroxyphenylpyruvic acid, alpha-Tocopherol, Cholesterol,myo-Inositol-2-monophosphate, 4-Hydroxysphinganine, Ceramide (dl8:1, C24:1), Ceramide (dl8:2, C24:0), Sphingomyelin (dl8:1, C16:0), 1, 2-Dioleoyl-sn-glycero-3-phosphatidyl-L-serine, 18:1 Lyso Phosphatidylcholine, CoenzymeQ9, Glucose, Glycerol, Glycerophosphates, Phosphate, 5-Methoxysphingosine, erythrosphingosine, Threonine, Diacylglycerides and Triacylglycerides.

    Abstract translation: 本发明涉及化学化合物危险分层的毒理学评估领域。 具体地说,涉及一种诊断肝毒性的方法。 它还涉及确定化合物是否能够在受试者中诱导这种肝毒性的方法以及鉴定用于治疗肝毒性的药物的方法。 此外,本发明涉及包含至少五种代谢物的特征值的数据收集,包括所述数据收集的数据存储介质,以及用于诊断肝脏毒性的系统和装置。 最后,本发明涉及一组代谢物或方法用于制备用于诊断受试者的肝脏毒性的诊断装置或组合物的用途。 对于每个性别,公开了不同的代谢组织模式,即不同的分析物组。 肝毒性标志物主要选自游离脂肪酸,还包括各种磷脂酰胆碱,羟基苯基丙酮酸,α-生育酚,胆固醇,肌醇-2-单磷酸,4-羟基鞘氨醇,神经酰胺(dl8:1,C24:1) 神经酰胺(dl8:2,C24:0),鞘磷脂(dl8:1,C16:0),1,2-二油酰-sn-甘油-3-磷脂酰-L-丝氨酸,18:1溶血磷脂酰胆碱,辅酶Q9,葡萄糖, 甘油,磷酸甘油酯,磷酸酯,5-甲氧基肌氨酸,红细胞素,苏氨酸,二酰基甘油酯和三酰基甘油酯。
