A new breed of CRO

Cresset Discovery Services (CDS) is a new breed of CRO. This is evident in two core principles that guide our work. The first is to use excellent in silico methods to aid small molecule discovery and design. We believe that computational chemistry tools provide intelligent short cuts, enabling us to select ‘20% of compounds that... Read More…

What rings do medicinal chemists use, and why?

The vast majority of small molecule drugs contain at least one ring. The rigidity, synthetic accessibility and geometric preferences of rings mean that medicinal chemistry series are usually defined in terms of which ring or rings they have at their core. However, ring systems are more than just scaffolds waiting to be elaborated: the electrostatic

Activity Atlas analysis of sodium channel antagonists. Part I: SAR of the right-hand side phenyl ring

Abstract Activity Atlas1 is a component of Forge2, Cresset’s powerful workbench for ligand design and SAR analysis. Activity Atlas models summarize the SAR for a series into a visual 3D model that informs design decisions and helps prioritize molecules for synthesis. In this case study, Activity Atlas’ activity cliff summary maps were used to analyze the... Read More…

New updated Spark reagent databases available for download

In our April 2016 newsletter we announced the release new reagent databases derived from eMolecules building blocks. Our aim was to closely relate Spark results to the chemistry that you want to use on your molecules and enable rapid assessment of reagent availability. We released an enhanced set of rules for processing reagents into R-groups

Capturing accessible chemistry space

There is often a divide between computational results and synthetic accessibility in the identification process of alternative compounds. However, there is now a way to produce results more quickly and precisely, and to ultimately accelerate the research process. Our article Chemical Reaction discusses: Scaffold hopping Case studies: Finding bioisosteres of DPP-IV inhibitors Identifying optimization routes Fragment reconnection Accessible

Engaging with Cresset Discovery Services

Cresset Discovery Services (CDS) offers bespoke in silico services for small molecule discovery. We do a lot of work in drug discovery and optimization for the pharmaceutical industry but we also work extensively in agrochemicals, flavors, fragrances – in fact, in any industry that involves work with small organic molecules. This post explains the process... Read More…

Examining the diversity of large collections of building blocks in 3D as presented at Sheffield Chemoinformatics Conference 2016

Abstract 2D fingerprint-based Tanimoto distances are widely used for clustering due the overall good balance between speed and effectiveness. However, there are significant limitations in the ability of a 2D fingerprint-based method to capture the biological similarity between molecules, especially when conformationally flexible structures are involved. Structures which appear to largely differ in functional group

Identifying possible protein targets

An academic group had identified a molecule that was active in a phenotypic assay. Due to its similarity to other compounds, they initially thought it was acting through a known pathway. However, further work revealed it was acting through a different pathway. The challenge was to identify the protein target. They chose a computational method... Read More…
