cox2: COX-2 Activity Data

Description

From Sutherland, O'Brien, and Weaver (2003): "A set of 467 cyclooxygenase-2 (COX-2) inhibitors has been assembled from the published work of a single research group, with in vitro activities against human recombinant enzyme expressed as IC50 values ranging from 1 nM to >100 uM (53 compounds have indeterminate IC50 values)."

The data are in the Supplimental Data file for the article.

A set of 255 descriptors (MOE2D and QikProp) were generated. To classify the data, we used a cutoff of $2^2.5$ to determine activity
