摘要

在一个大型数据库(n = 1706)中建立了hBACE-1抑制剂(pIC50)的稳健定量构效关系(QSARs)。提出并检验了模型预测潜力的新统计准则。这两个指标分别是相关理想指数(IIC)和相关强度指数(CII)。自洽模型系统是验证qsar模型预测潜力的一种新方法。使用CORAL软件(http://www.insilico.eu/coral)对验证集获得的模型统计质量的特征是平均决定系数R2 v= 0.923, RMSE = 0.345。提出了三种新的有希望成为hBACE-1抑制剂的分子结构。

The searching for agents for Alzheimer’s disease treatment via the system of self-consistent models

Abstract Robust quantitative structure-activity relationships (QSARs) for hBACE-1 inhibitors (pIC50) for a large database (n = 1706) are established. New statistical criteria of the predictive potential of models are suggested and tested. These criteria are the index of ideality of correlation (IIC) and the correlation intensity index (CII). The system of self-consistent models is a new approach to validate the predictive potential of QSAR-models. The statistical quality of models obtained using the CORAL software (http://www.insilico.eu/coral) for the validation sets is characterized by the average determination coefficient R2 v= 0.923, and RMSE = 0.345. Three new promising molecular structures which can become inhibitors hBACE-1 are suggested.

期刊介绍： Toxicology Mechanisms and Methods is a peer-reviewed journal whose aim is twofold. Firstly, the journal contains original research on subjects dealing with the mechanisms by which foreign chemicals cause toxic tissue injury. Chemical substances of interest include industrial compounds, environmental pollutants, hazardous wastes, drugs, pesticides, and chemical warfare agents. The scope of the journal spans from molecular and cellular mechanisms of action to the consideration of mechanistic evidence in establishing regulatory policy. Secondly, the journal addresses aspects of the development, validation, and application of new and existing laboratory methods, techniques, and equipment. A variety of research methods are discussed, including: In vivo studies with standard and alternative species In vitro studies and alternative methodologies Molecular, biochemical, and cellular techniques Pharmacokinetics and pharmacodynamics Mathematical modeling and computer programs Forensic analyses Risk assessment Data collection and analysis.
