Structure Analysis of Natural Products
Many databases currently cover only a small fraction of the known natural products (NPs), so an increasing number of computational methods are being used to predict mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectra for NPs, sometimes in combination with structure generators. Aiming to make full use of available experimental resources, scientists have applied analytical and computational methods in tandem to perform structural analysis of NPs as well as NPs with undesirable properties as early as possible.
BOC Sciences can provide a diversity of structure analysis of natural products services to provide high quality NPs for the natural compound library construction.

- Machine learning
Our databases contain comprehensive measured analytical data such as bioactivity, chromatographic data, MS and NMR spectroscopy data for known natural products and their interrogation with computational methods.
Our well-designed algorithms can convert spectral data of natural products into representational form including reduced to peak lists, numerical vectors, trees, which can provide some valuable information about chemical classes and functional groups of natural product. Then, our experts can compare the spectra and rank them based on their similarity. Moreover, we provide additional manual analysis services.
Various dimensionality reduction techniques such as principal component analysis (PCA), clustering methods and/or discriminant analysis are available for identifying NPs of interest.
CD BioScience is committed to offering high quality CASE service to identify the correct structure of a target compound based on available spectral data. We can use CASE to enumerate structures that are consistent with experimental (spectral) data and rank them according to their probability. Our well-developed CASE technique has the following features:
In addition, we are able to apply machine learning to the structural analysis of natural product molecules: A convolutional neural network-based approach is employed for rapid identification of new NPs.
