AstraZeneca uses ACD/Labs software to make analytical data accessible as part of their Global Analytical Database. In this presentation, you’ll get an overview of how this database is used by chemists and analysts for data processing, data storage, and knowledge sharing. Two case studies are also shown to highlight how access to centralized data can...

Sanofi partnered with ACD/Labs to develop an automated lab tool combining LC/MS and 1H NMR to help organic chemists efficiently verify their structures. This tool collects, compiles, and evaluates the analytical data and the proposed structure once they are available, and sends the results to the chemist. The pilot project for this system is presented...

The Pfizer Structure Elucidation Group (SEG) spans two continents, supporting research and development in the UK and USA. In this presentation John talks about their structure elucidation workflow for assisted data processing and analysis, and centralized data management. John also presents some interesting case studies of puzzled they have solved.

The technological development of LC-MS instrumentation has led to significant improvements of performance and sensitivity, enabling high-throughput analysis of complex samples, such as plant extracts. Most software suites allow preprocessing of LC-MS chromatograms to obtain comprehensive information on single constituents. However, more advanced processing needs, such as the systematic and unbiased comparative metabolite profiling of...

Performance of several library search algorithms (against EI mass spectral databases) implemented in commercial software products (ACD/SpecDB, ChemStation, GC/MS Solution, and MS Search) was estimated. Test set contained 1000 mass spectra, which were randomly selected from NIST’08 (RepLib) mass spectral database. It was shown that composite (also known as identity) algorithm implemented in ms search...

A major problem in the discovery of new biologically active compounds from natural products is the re-isolation of known compounds. To address this problem, dereplication strategies are needed that enable crude extracts to be screened for the presence of known compounds before isolation efforts are initiated. The specific attributes of this dereplication methodology include a...
