SPRESIweb

SPRESIweb is the online interface to the SPRESI structure and reaction database of 5.62 million compounds and 4.34 million reactions. Parameters that can be searched for include:

  • Chemical structure
  • Chemical reaction
  • Bibliographic information
  • Reaction conditions / name
  • Reaction similarity
  • Catalyst
  • Solvent
  • Yield
  • Physicochemical property

The data searchable via SPRESIweb has been collected by the All-Union Institute of Scientific and Technical Information of the Academy of Sciences in the USSR (VINITI) and the German Zentrale Informationsverarbeitung Chemie in Berlin (ZIC) since 1974.

SPRESIweb allows the Synthesis Tree Searched to retrieve reaction trees to or from a given target molecule. A database of over 600 named reactions is also accessible via SPRESIweb, giving real-life experimental examples of classic literature reactions.

ACD/I-Lab

ACD/I-Lab is an online structure-based prediction engine which calculates physicochemical properties and NMR spectral information. Databases of many properties and spectra can also be searched.

ACD/I-Lab allows the user to:

  • Predict and search databases of NMR spectra (1H, 13C, 15N, 19F, 31P), chemical shifts and coupling constants
  • Predict and search databases of physicochemical properties (logP, pKa , solubility)

Predictions are made using algorithms developed by ACD/Labs, based on chemical structures entered by:

  • Searching the chemical dictionary of >36,000 names and >8,900 chemicals
  • Drawing into the I-Lab interface or pasting a structure from ACD/ChemSketch
  • Uploading a molecular structure file (.mol, .skc, .cdx, .sk2)
  • Typing or pasting a SMILES string

Updates to ACD/I-Lab have been implemented, improvements include:

  • Zooming feature for 1H and 13N NMR predicted and literature spectra
  • Reports exportable as PDFs
  • Image resizing in chemical structure
  • Searching of 13C then 1H NMR database
  • Copy and pasting

Peter Scott announced as the Chair of the National Chemical Database Service Advisory Board

We are pleased to announce Professor Peter Scott of the University of Warwick as the Chair of the National Chemical Database Service (NCDS) Advisory Board. The purpose of the Advisory Board is to oversee the management and use of the Service, in addition to reviewing performance and strategy. The Advisory Board consists of independent representatives from the UK chemistry research community, EPSRC and UK libraries. We are delighted to welcome Peter as the new Chair.

Professor Peter Scott FRSC is a Professor of Chemistry and Deputy Head of Faculty of Science at the University of Warwick. Peter’s research interests lie in the field of metallo-organic chemistry. His group works on designing self-assembling chiral systems, and investigating their use for medical applications and as catalysts for enantioselective transformations of organic molecules. His group also synthesises and characterises molecular materials and polymers, and collaborates with biologists and material scientists.

Peter received his BSc at the University of Salford before completing his DPhil at the University of Oxford. Postdoctoral positions at the Universities of Konstanz and Sussex were followed by his appointment as a Lecturer in Chemistry at the University of Sussex. Peter moved to Warwick in 1997.

“What is the most exciting aspect of the National Chemical Database Service?”

If the RSC NCDS can integrate sources of data in such a way as to make them useful to chemists, rather than just database experts, then it will create a step change in its utility for chemical sciences research. A good example of this is ChemSpider which from a chemical structure presents us, for free, with an integration of data sources that is bigger than the sum of the parts. As a synthetic chemist I am also excited about micropublication and the idea of crowdsourced improvement of existing literature data and protocols via mechanisms such as ChemSpider SyntheticPages and ChemSpider Reactions. Finally, if the RSC can provide leadership to the UK and world chemistry community in the integration of data sources, such as ELNs, then that will be a famous achievement.

“…and how does this relate to the future of the Service?”

The RSC has set out the vision and strategy, and is rolling out the programme. At the core of this for me is useability and – importantly – engagement and contribution from the worldwide community of chemists and other scientists. I think that in the not too distant future, the NCDS will be viewed by Members as one of the essential activities of the RSC alongside Publications, Scientific Prizes and Events.
