三羟甲基丙烷皮肤致敏分析数据

采集了化学品毒性数据，通过系统性的多步筛选策略和交叉参照评估方法，并结合毒性机理和毒理数据的分析得到用于计算的源物质信息，应用到三羟甲基丙烷对于皮肤致敏的计算，分析得出三羟甲基丙烷对皮肤致敏各类指标的科学数据，为进一步的毒性评估和安全性分析提供了依据。（1）数据来源：使用 QSAR Toolbox 4.7.1 软件，从该软件数据库中采集物质和毒性数据，涵盖生物累积、化学活性、生态毒性、经口毒性、皮肤刺激性等领域。
（2）数据处理：
初步筛选： 应用首要分类规则，从数据集中提取64761种物质作为初始筛选基础。
子分类筛选： 逐步实施以下6类分层筛选规则，具体为化学元素（子分类）、蛋白质结合效力Cys（DPRA 13%）（子分类）、蛋白质结合效力Lys（DPRA 13%）（子分类）、ECOSAR的水生毒性分类（子分类）、解偶联剂（MITOTOX）（子分类）、急性口服毒性（子分类）。
毒性机理与毒理数据分析：确定目标源物质，进行交叉参照计算，运用相似物法对三羟甲基丙烷的皮肤致敏进行推算，获得三羟甲基丙烷对皮肤致敏的科学数据。

This dataset collects chemical toxicity data, and obtains source substance information for computational use through systematic multi-step screening strategies and cross-reference assessment methods combined with analysis of toxicity mechanisms and toxicological data. It is applied to the calculation of trimethylolpropane-induced skin sensitization, and scientific data on various indicators of trimethylolpropane-induced skin sensitization are derived via analysis, providing a basis for further toxicity assessment and safety analysis.
(1) Data Source: Substance and toxicity data were collected from the database of QSAR Toolbox 4.7.1 software, covering fields including bioaccumulation, chemical reactivity, ecotoxicity, oral toxicity, skin irritation and others.
(2) Data Processing:
Preliminary Screening: Primary classification rules were applied to extract 64,761 substances from the dataset as the basis for initial screening.
Sub-category Screening: Six types of hierarchical screening rules were implemented step-by-step, specifically including chemical elements (sub-category), protein binding potency Cys (DPRA 13%) (sub-category), protein binding potency Lys (DPRA 13%) (sub-category), aquatic toxicity classification of ECOSAR (sub-category), uncoupling agents (MITOTOX) (sub-category), and acute oral toxicity (sub-category).
Toxicity Mechanism and Toxicological Data Analysis: Target source substances were identified, cross-reference calculations were conducted, and the skin sensitization of trimethylolpropane was estimated using the analog approach, yielding scientific data on trimethylolpropane-induced skin sensitization.
