Capturing and applying knowledge to guide compound optimisation

Matt Segall

Matt Segall gave this presentation at the ACS National Spring Meeting 2018 in New Orleans.


Compound design requires a combination of knowledge and expertise from different perspectives: understanding of structure-activity relationships (SAR), based on data from previously studied compounds; expertise from diverse fields to define the multi-parameter optimisation (MPO) objectives of a project; and knowledge of synthetic strategies that may be applicable to create the next rounds of compounds for investigation. All of these forms of knowledge can be captured and applied computationally: Machine learning methods can generate quantitative structure-activity relationship (QSAR) models to predict the properties of novel, virtual compounds; MPO methods capture the desired property criteria for a successful compound for a specific project and rigorously prioritise ideas for consideration; and, optimisation strategies can be captured as structural transformations that reflect steps made in previous chemistry projects.

Optbrium launches StarDrop 6.5

Monday, 18 June 2018 15:20

We are pleased to announce the launch StarDrop 6.5. The latest release introduces WhichP450, a new feature in StarDrop’s P450 metabolism module that predicts which human Cytochrome P450 enzymes are the major metabolising isoforms for a novel compound. Understanding how a compound is metabolised enables identification and analysis of its potential metabolites, and guides the design of molecules with...
