Hit Selection When You’re Strapped for Cash

I came across a paper from Chaput et al that describes an approach to hit selection from a virtual screen (using docking), when follow-up resources are limited (a common scenario in many academic labs). Their approach is based on using multiple docking programs. As they (and others) have pointed out, there is a wide divergence […]

Cryptography & Chemical Structure Search

Encryption of chemical information has not been a very common topic in cheminformatics. There was an ACS symposium in 2005 (summary) that had a number of presentations on the topic of “safe exchange” of chemical information – i.e., exchanging information on chemical structures without sharing the structures themselves. The common thread running through many presentations was to […]

Maximally Bridging Rings (or, Doing What the Authors Should’ve Done)

Recently I came across a paper from Marth et al that described a method based on network analysis to support retrosynthetic planning, particularly for complex natural products. I’m no synthetic chemist so I can’t comment on the relevance or importance of the targets or the significance of the proposed approach to planning a synthetic route. […]

Surveying the Opinion of Chemists

As part of a project I was wondering about reports of surveys that collected chemists assessments of differnt things. More specifically, I wasn’t looking for crowd-sourcing efforts for data curation (such as the in the Spectral Game) or data collection. Rather, I was interested in reports where somebody asked a group of chemists what they […]

Post-doc (Molecular Informatics) Opening at NCATS

I have a post-doc opening in the Informatics group at NCATS, to work on computational aspects of high throughput combination screening – topics will include predicting drug combination response, visualizing large combination screens (> 5000 combinations) and so on. The NCATS combination screening platform thas tested more than 65,000 compound combinations (in checkerboard style which […]
