分子环境描述在化学信息学中有许多应用,包括化学位移预测。分层排序的球形环境(软管)代码是最流行的此类描述。我们开发了一种方法,用立体化学信息来扩展这些信息。它能够区分在传统软管代码中被认为相同的原子。我们的方法的使用是通过对nmrshitDB2数据库中分子的化学位移预测来演示的。我们给出了完整的规范和实现。
Descriptions of molecular environments have many applications in chemoinformatics, including chemical shift prediction. Hierarchically ordered spherical environment (HOSE) codes are the most popular such descriptions. We developed a method to extend these with stereochemistry information. It enables distinguishing atoms which would be considered identical in traditional HOSE codes. The use of our method is demonstrated by chemical shift predictions for molecules in the nmrshiftdb2 database. We give a full specification and an implementation.
