InChI Version 1.07 Approved

IUPAC InChI moves to GitHub to support sustainable chemical standards development

“The InChI (International Chemical Identifier) is a widely used standard chemical identifier that enables the connection and interoperability of chemistry data across the web. The core code and development framework of the InChI has now been migrated to GitHub, providing a foundation to support future extensions of the standard and associated applications, and to broaden the expertise supporting the standard. The first milestone of this work is the 1.07 version, recently approved by IUPAC (International Union for Pure and Applied Chemistry) and the InChI Trust and available for download at GitHub.

The InChI has been used to identify unique chemical structures for over 20 years and is implemented in chemistry toolkits and in databases across the world. The work to maintain and develop the software rested on the shoulders of one expert, Igor Pletnev, and following his sad death in 2021, it became urgent to move the code to a more open model. Completion of this move with a new fully tested and approved release makes the development of this digital standard more transparent. It will also enable the extension of the InChI to further classes of chemical compounds, in particular inorganic and organo-metallic compounds, as well as future modernisation of the codebase.”

“For over 20 years, InChI (International Chemical Identifier) has uniquely identified chemical structures in databases, journal articles, and supplier catalogues, across the web. It helps quickly determine if a chemical compound in a library is present in an internal repository or match data about chemical compounds across different databases. Reliable standards like InChI are essential for the FAIR principles (Findable, Accessible, Interoperable, Re-usable) in chemical data exchange.”

2024 CSA Trust Grant Report by Ariadna Peiro

Thanks to the CSA Trust Grant, I had the opportunity to attend the 9th Strasbourg Summer School in Chemoinformatics (CS3-2024). This renowned event, held in the European Capital city of Strasbourg, offered enriching lectures and hands-on tutorials covering the latest topics in the field.

The program offered diverse perspectives on Artificial Intelligence in chemistry, addressed the validation needs in working on Big Data, and shared innovative workflows. It also explored new trends in Quantitative Structure-Activity Relationship (QSAR) modeling and in silico pharmacology, featuring insights from leading international scientists.

As a doctoral candidate in Chemoinformatics and Bioinformatics, focusing on Drug Discovery, I recently achieved a milestone by publishing an open-source program named PDB-CAT (PDB Classification and Analysis Tool). This tool is the first automated, open-source solution designed for classifying structures in the Protein Data Bank.

One highlight of my participation was presenting a poster announcing the publication of PDB-CAT. To my delight, my work was recognized with the Best Poster Prize.

Beyond the technical knowledge, attending this international workshop significantly enhanced my soft skills. The motivational environment drove my dedication to my research.

Moreover, the city of Strasbourg, with its rich history and vibrant culture, added a special touch to this unforgettable experience. The beautiful surroundings provided a perfect setting, making the entire journey even more memorable.

In conclusion, the 9th Strasbourg Summer School in Chemoinformatics was more than just an academic event. It was a transformative experience that expanded my comfort zone and solidified my commitment to advancing the field of Drug Discovery. As I continue my doctoral journey, I carry with me the invaluable insights, skills, and personal relationships gained from this opportunity.

CSA Trust Grant Awardees 2024

Nils van Staalduinen (left), Ivan Yankov (middle), Ariadna Peiro (right)

Nils van Staalduinen is a PhD candidate at the Institute for Physical Chemistry, RWTH Aachen Germany where he works under the guidance of Prof. Bannwarth, focusing on theoretical chemistry and cheminformatics. His research concentrates on MolBar, a molecular identifier for chemical structure databases. His current work is an extension of his Master’s thesis for which he won the MSE Master Award of RWTH Aachen. MolBar was launched in March 2024 and has since been downloaded several hundred times. He balances his PhD work with a role at BASF SE, where he further develops chemical database pipelines with a focus on cheminformatics algorithms that streamline molecule registration and tautomer searchers.

His CSA Trust grant funds will provide financial support for research visits to the laboratory of Professor Todd Martinez (see: https://mtzweb.stanford.edu) for the integration of MolBar into the Nanoreactor at Stanford University (CA) and for payment of travel expenses to attend two conferences – the 2024 German Cheminformatics Conference and the 2024 RDKit UGM.

Ivan Yankov is currently a PhD student at the University of Strathclyde (U.K). His research is focused on integrating Artificial Intelligence (AI)  methods into computational design across drug discovery, drug development, and structure determination of biological materials. The goal is to accelerate in-silico design pipelines by modelling thermodynamic properties of nucleic acids and their complexes. Furthermore, AI NMR data analysis systems can be fine-tuned to nucleic acid and nucleic acid ligand complexes to eliminate inefficiencies and reproducibility challenges in the structure determination process from NMR data. The innovation will eliminate bottle necks in the in-silico design and structure determination stages.

Ariadna Peiro, is currently a PhD student in the Cheminformatics and Nutrition Research Group at Rivira i Virgill University, Spain. Her thesis focuses on the fields of virtual screening and drug discovery, with an emphasis on SARS-CoV-2 Proteases. She is involved in a project called NEXT-PANDEMICS that was created after the coronavirus pandemic in response to the vast amount of data generated from vaccine and antiviral research. The main objective of the project is to develop new open-source tools to enhance the effectiveness of virtual screening and predict binding affinity in silico. Additionally, these tools will be applied to determine a list of leads to search for antivirals. Moreover, this discovery would be applied to Zika and Dengue viruses.  CSA Trust Grant funds will be used to attend summer courses at the Strasbourg summer school in Cheminformatics.

“Cheminformatics: A Digital History ‒ Part 4. Ladies First” by Wendy Warr

“In Part 4 of this historical series of articles, I am honoured to follow in the distinguished company of Peter Willett, Henry Rzepa and Johnny Gasteiger, all of whom had a significant influence on me during my progress in the path of cheminformatics. I started out as a synthetic organic chemist. When I matriculated at Oxford in Michaelmas 1964 the ratio of women to men Oxford undergrads in all subjects was 1:5. (At Cambridge it was 1:7, but Cambridge had only 2-3 women’s colleges then, while Oxford had five.) I was one of seven women in total from the five Oxford colleges who studied for chemistry Part I in 1964-1967. I don’t know how many men there were, but the number was certainly over 200. A great deal of progress has since been made as regards equality. On the Oxford undergraduate course in 2023 there are 421 men (57%) and 317 women (43%). There is also a web page about women in chemistry. Jonathan Goodman tells me that third years reading chemistry at Cambridge in Michaelmas 2023 are about 40% female.

I was at Lady Margaret Hall, Oxford, whose undergraduates were always addressed as ‘ladies’: hence the title of this article. One of my sons says that women have been the dark matter of science: they have always been there and are immensely important, but they have only recently been recognised. In 1964, when I went up to Oxford, Dorothy Crowfoot Hodgkin won the Nobel Prize in Chemistry, the first woman winner since the Curies early in the century. Historically, eight out of 191 chemistry Nobel Laureates have been women, but things are improving: five of the eight winning women were recognised in 2009 or later.”
