2025年2月21日 · The Toxicity Estimation Software Tool (TEST) was developed to allow users to easily estimate the toxicity of chemicals using Quantitative Structure Activity Relationships (QSARs) methodologies. QSARs are mathematical models used to predict measures of toxicity from the physical characteristics of the structure of chemicals (known as molecular ...

All reports made with ToxTool® carry a security QR code, to guarantee the origin and your ownership of the data. Integrated with NOAEL In Silico predictive data and implemented in view of the upcoming challenges of the Next Generation Risk Assessment (NGRA).

The software-based tool “ToxRTool” (Toxicological data Reliability Assessment Tool) provides comprehensive criteria and guidance for evaluations of the inherent quality of toxicological data, thus making the decision process of assigning reliability …

Toxicological tool to explore ingredient database and evaluate cosmetic products

ProTox 3.0 enables uncomplicated predictions of different levels of toxicities. To conduct a toxicity prediction, please click on the image. Toxic doses are often given as LD50 values in mg/kg body weight. The LD50 is the median lethal dose meaning the dose at which 50% of test subjects die upon exposure to a compound.

2024年12月23日 · EPA’s computational toxicology research efforts evaluate the potential health effects of thousands of chemicals. The process of evaluating potential health effects involves generating data that investigates the potential harm, or hazard of a chemical, the degree of exposure to chemicals as well as the unique chemical characteristics.

To comprehensively assess the toxicity of molecules from multiple dimensions, including basic drug toxicity, cell toxicity, target toxicity, pathway toxicity, organ toxicity, clinical toxicity, and environmental toxicity.

QSAR是目前国内外一个活跃的研究领域，美国环境保护署（United States Environmental Protection Agency，简称US EPA）就基于QSAR开发了针对化学物质毒性预测的软件——Toxicity Estimation Software Tool (T.E.S.T)。 T.E.S.T软件可根据大量的数据处理和统计识别目标化合物中潜在的有毒基团，还能快速地分析与目标物质结构相似的化合物的毒性，进一步综合预测目标物质 …

Toxtree is a full-featured and flexible user-friendly open source application, which is able to estimate toxic hazard by applying a decision tree approach. Toxtree could be applied to datasets from various compatible file types.
