Bond Artifacts in SketchEl2, and round-trip MDL Molfile

wmk_artifacts01Awhile back I described the idea of bond artifacts, which are layered on top of a core cheminformatics representation to give the rendering engine the hints it needs to make the visual diagram look like what chemists want to see (without breaking the underlying machine readability). Now this enhancement has been added to the open source WebMolKit framework and the derived SketchEl2 drawing app. Furthermore, the artifacts can survive a round trip encoding with the industry standard Molfile CTAB format.

Adventures with combining PubMed and ChEMBL

One of the things I’ve been investigating lately is the open access segment of PubMed, which is a rather massive collection of open access medicine-relevant publications, with accompanying full text.  Similarly with the ChEMBL database, which is focused on structure-activity data traceable back to the original literature document from which each datapoint was curated. This is all for the purpose of advancing the BioAssay Express mission of making the world’s bioassay protocols machine readable (aka FAIR). Continue reading

American Chemical Society meeting: Autumn 2018 Boston

ACS time is sneaking up on us, as it tends to do: in about 2 months from now – August 2018 – a large proportion of the world’s chemistry community will be converting in Boston, including myself. This particular city is probably my favourite venue, simply by virtue of being such a massive hub for various forms of chemistry and derived industries, such as small molecule drug discovery.

My presentation will be on the Wednesday:

Paper ID 2972556 / CINF 150
Title Bringing assay protocols into the age of informatics
Session Drug Discovery: Cheminformatic Approaches
Section Division of Chemical Information
Time 1:30pm, Wednesday 22 August 2018

As for the last couple of meetings, I will be presenting aspects of the BioAssay Express project, on behalf of Collaborative Drug Discovery. Our team has been quietly expanding in numbers and working hard making the product more powerful and more polished, so there are lots of new features to talk about!
