PubChem will discontinue several bioactivity analysis tools on November 1, 2018. This includes the BioActivity Summary, BioActivity DataTable, SAR, Structure Clustering, and Plot Service. A help document page is available outlining alternatives with the same or similar functionality.

BioAssay Tools:

  SAR
The Structure-Activity Analysis service clusters compounds and bioassays simultaneously using chemical structure, biological outcome, and target information. This service provides exploratory tools that allows one to identify structure-activity relationship and examine target selectivity and specificity of a compound. Please specify compounds and bioassays using the given input methods.
