Natural Product Updates: now structure-searchable in ChemSpider

Natural Product Updates

Natural Product Updates (NPU) provides graphical abstracts of new developments in natural product chemistry, selected from dozens of key primary journals. Coverage includes:

  • Isolation studies
  • Biosynthesis
  • New natural products
  • Known compounds from new sources
  • Structure determinations
  • New properties and biological activities     

Around 200 graphical abstracts are contained in each monthly bulletin, including structure diagrams, trivial and taxonomic names, molecular formulae, physical and biological properties

Browse this Database

Subscribers to the monthly print bulletin also have free access to Natural Product Updates Online – the fully searchable web database which allows users to search across all items published in Natural Product Updates to date. This service provides full text search capability on a variety of terms.

An email alerting service is also available, allowing users to sign up for an email message every time a new monthly bulletin is published online.

Natural Product Updates, is now structure searchable in ChemSpider
