The molecular structure and NMR chemical shift information of a compound can be combined to form powerful models of biological activity. NMR spectral data and structure information can be combined on a structural template analogous to 3D-QSAR methodology or orientation independently in spectral space. Surprisingly, quantitative spectrometric data-activity relationship (QSDAR) models built on structure templates are inferior to multi-dimensional QSDAR models built in spectral space. 3D-QSDAR modeling could be useful for estimating chemical toxicity, risk assessment of environmental contaminants and drug lead-compound identifications.
化合物的分子结构和核磁共振化学位移信息可以结合起来,形成强大的生物活性模型。核磁共振光谱数据和结构信息可以在类似于三维定量构效关系(3D-QSAR)方法的结构模板上结合,或者在光谱空间中独立定向结合。令人惊讶的是,基于结构模板构建的定量光谱数据-活性关系(QSDAR)模型不如在光谱空间中构建的多维QSDAR模型。三维定量构效关系建模可用于估计化学毒性、环境污染物的风险评估以及药物先导化合物的鉴定。
