Free-Wilson in the 21st Century – evolution of a versatile toolkit for SAR analysis

When drug discovery projects are transferred, then rapidly assessing the available SAR in both overview and in numerical detail is a prerequisite for effective computational chemistry input. Following multiple company acquisitions, regular requirements for the approach has led to an effective and fast platform for Free-Wilson [1] based SAR review: in fact the utility is sufficient that it can for a useful reporting or project browsing tool for the busy modeller.

In this talk it is shown how a carefully crafted PDF report can be combined with “on the fly” Matched Molecular Pair [2] and other drill downs to provide a versatile platform for SAR exploration and presentation that is appealing and to medicinal chemists.
