Recently I described an open source tool for editing chemical mixtures, using a machine readable format. Now we have a proof of concept tool for starting with the kinds of text descriptions people use to describe mixtures, and recreating the actual components in their full glory. Continue reading →

The Molecular Notebook desktop app for chemical structure & data content creation has gotten a refresh on the iTunes AppStore: it now responds to the dark-mode preference. Continue reading →

Awhile 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.

At CDD we’ve recently begun a new project to define a common format for mixtures of chemicals, along with an open source editor, and impending tools for generating data from text content. The work-in-progress editor is now openly available on GitHub. Continue reading →

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 →

As of now, there’s a KNIME plugin that can be used to access data from the BioAssay Express. The plugin uses the existing API functionality that can grab all of the available bioassay protocols, or a subset as defined by a query, and bring them into the KNIME ecosystem as a table which can be processed using the multitude of other node types.

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!

The interactive sketcher feature in WebMolKit now has a more accessible demo page at molmatinf.com/webmolkit.html. Continue reading →

Last week I had the pleasure of representing Collaborative Drug Discovery at the BioIT World Hackathon, themed around FAIR data principles. Continue reading →

After a bit of inattention, the MolPress project has received some important new features: chemical objects are rendered within the editor itself, and there’s a better onboarding process for bringing in reactions. Continue reading →
