控制和调节强调生命系统和环境中的化学行为的物理化学性质的能力是绿色化学的“核心”。对于事先设计为具有生物活性的化学类别尤其如此,例如杀虫剂,在这些类别中,意外不良后果的可能性很高。我们最近提出了一个设计向量框架,利用生态毒性和间接光降解的有效计算模型作为一个有用的、基于准系统的工具来筛选现有的和设计新的农用化学品。在这里,我们描述了一个数据库的开发,该数据库集成了我们的模型,该模型将结构和亚结构特征与过程指标联系起来,以及美国环境保护局登记的所有具有光降解核心的农用化学品的相应预测数据(785种化合物和18,000多种与有色溶解有机物(CDOM)的成对相互作用)。该数据库可通过结构和非结构识别符(例如,化学类别、可氧化核心、物理化学和电子性质等)进行搜索。协助进行化学品选择、危害和替代评估。重要的是,它可以很容易地更新和扩展,以帮助在行业、政府和学术界之间进行交互式数据共享。该项目的总体目标是鼓励在基于系统的农药设计方面做出更大的努力,使该平台与基于目标的计算方法相结合,并纳入跨行业新产品开发的发现阶段。
The ability to control and tune physicochemical properties that underscore chemical behavior in living systems and the environment is at the “heart” of green chemistry. This is especially true for chemical classes designed a priori to be biologically active, such as pesticides, where the chance of unintended adverse outcomes is high. We recently proposed a design-vectoring framework, leveraging validated computational models of ecotoxicity and indirect photodegradation as a useful, quasisystems-based tool for screening existing and designing new agrochemicals. Here, we describe the development of a database that integrates our models, which link structural and substructural features to process metrics, and corresponding predicated data for all agrochemicals with photodegradable cores on the U.S. Environmental Protection Agency’s registry (785 compounds and over 18,000 pairwise interactions with chromophoric dissolved organic matter, CDOM). The database is searchable by structural and nonstructural identifiers (e.g., chemical class, oxidizable core, physicochemical and electronic properties, etc.) to aid in chemical selection, hazard, and alternative assessment. Crucially, it can be easily updated and augmented to aid in interactive data-sharing across industry, government, and academia. The overarching goal of this project is to spur grander efforts in systems-based design of pesticides that would see this platform paired with target-based computational methods and incorporated into the discovery phase of new product development across industry sectors.
