Reaxys Medicinal Chemistry helps to answer critical drug R&D questions:

  • What substances interact with my target?
  • What types of interaction occur between my substance and my target?
  • A drag-and-drop Query Builder that enables all users to select and define search parameters
  • What interactions do other substances with similar structures have?
  • What is the comparative affinity of different substances for my targets?
  • What phenotypic screening has been done on similar substances?
  • Which of my drug candidates has the highest chance of success?
  • Who are the key researchers working on similar substances and targets?

Harmonized data for ease of comparison

All the data in Reaxys Medicinal Chemistry, including content from third-party databases, are harmonized using Reaxys standards for chemicals, targets and bioactivities. Elsevier life science experts normalize the data; map concepts and glossaries; and remove inconsistent data and duplicate citations.

From quick and intuitive searches to flexible and powerful queries

See how Quick Search works - Reaxys |Elsevier Soltuions

To facilitate rapid retrieval of bioactivity data and citations, Reaxys Medicinal Chemistry offers users Quick Search: an intuitive interface that accepts queries consisting of natural keywords and/or substance structure or reaction drawings.

Rapid assessments of substance and target interactions

Reaxys Medicinal Chemistry has a Heatmap that provides a clear overview of the relationships between substances and their targets. Its display includes a quantifier for this relationship in the form of pX values, which are normalized substance–target affinity values assigned to the data.

Integration into existing workflows

Reaxys Medicinal Chemistry offers an Application Programming Interface (API) for flexible information delivery and real-time programming access to the content and system and a Flat File for exporting structures, related reaction data and bioactivity information for in-house usage, e.g., QSAR/QSPR modeling and chemical space analysis.

It is also fully integrated with Reaxys, enabling deep exploration of the structures and physicochemical properties of known compounds and providing access to reaction data and synthesis route information.
