Chemical Science is moving to weekly issues!

14 Dec 2017

We have exciting news here at Chemical Science! From 2018, the journal will be moving from publishing monthly issues to weekly issues. This is one of the biggest changes to the journal since it was launched in 2010.

Why are we doing this? By publishing weekly issues, we’ll be able to make our articles more accessible to keep up with the large number of articles we currently publish. With the journal being free to access, it would be a shame for the community to miss the latest exceptional findings due to less frequent, larger issues.

What are the benefits for the chemical sciences community? For our readers, it will be easier to find the latest relevant articles, with weekly table-of-contents alerts and a shorter contents list for each issue. For our authors, articles will be assigned page numbers more quickly and will be indexed in databases such as PubMed Central® sooner.

You can learn more about this change in our Editorial by Executive Editor, May Copsey, published in the first ever Chemical Science weekly issue!

Meet Vincent Artero: Chemical Science Associate Editor

06 Dec 2017

We are delighted to welcome Professor Vincent Artero as Chemical Science Associate Editor, handling submissions in the area of energy.

Vincent Artero graduated from the Ecole Normale Supérieure (Ulm) and the University Pierre et Marie Curie (Paris 6). He received his Ph.D. in 2000 under the supervision of Professor A. Proust and Professor P. Gouzerh. His doctoral work dealt with organometallic derivatives of polyoxometalates. After a postdoctoral stay at the University of Aachen (Aix la Chapelle) with Professor U. Kölle, he joined in 2001 the group of Professor M. Fontecave in Grenoble where he obtained a position in the Life Science Division of the CEA.

Since 2016, he leads the SolHyCat group as Research Director in the Laboratory of Chemistry and Biology of Metals (a research unit cooperated by CEA, CNRS and Univ. Grenoble Alpes) in Grenoble. Vincent Artero received the “Grand Prix Mergier-Bourdeix de l’Académie des Sciences” in 2011. In 2012, he was granted with a Consolidator Grant from the European Research Council (ERC). He currently acts as Chair of the Scientific Advisory Board of the ARCANE Excellence Laboratory Network (LABEX) for bio-driven chemistry in Grenoble and co-chair of the French Research Network (GDR) on solar fuels.

His current research interests are in the structural and functional modelisation of hydrogenases, the design of artificial organometallic proteins and the photo- and electro-production of hydrogen. Vincent is keen to receive submissions in his area of expertise. Below is a list of recent Chemical Science articles published within the energy-related field – all free to read.

Old and new spectroscopic techniques team up to decipher intricate alkaloids

04 Dec 2017

Cutting-edge strategies set to increase our access to chemical space after researchers use them to verify unprecedented structures

Scientists have identified the structures of two marine natural products that were previously considered too complicated to characterise.¹ A combination of well-known spectroscopic tools and new experiments probing orientation-dependant bonding allowed the team to unpick the structures.

Natural products are a rich source of pharmacologically-active compounds. The problem is: they are often difficult to purify and identify.

Gary Martin, of Merck Research Laboratories in the US, and Kirk Gustafson, from the US National Cancer Institute, have been studying and characterising natural products for years. ‘There has been a continuing flow of incorrectly reported complex natural product structures into the published literature … at present, there are more than 1200 structure revision papers. Stopping investigators from reporting incorrect structures in the first place will free up their time to pursue and identify new molecular entities,’ they say.

What’s left isn’t always right in total synthesis

15 Nov 2017

Using detective skills that would make Hercule Poirot proud, researchers in the US have solved a longstanding mystery around the absolute configuration of natural product (+)-frondosin B.¹

Source: Royal Society of Chemistry Summary of the enantioselective frondosin B syntheses reported to date

(+)-Frondosin B is part of a family of marine sesquiterpenes found in underwater sponges that exhibit anti-inflammatory properties and have potential applications in anticancer and HIV therapy. Starting with Samuel Danishefsky’s route in 2001,² there have been 5 total syntheses of (+)-frondosin B. However, due to a discrepancy in the optical rotation of the final product during Dirk Trauner’s 2002 synthesis,³ which was observed to have S rather than the expected R configuration, there has been a fierce debate in the synthetic community about the true stereochemistry at C8 in the natural product. After more than decade of attempts by synthetic organic chemists to explain this, particularly focused on different inversion processes, no definitive answer had arisen.

Benchmark for molecular machine learning

13 Nov 2017

A team at Stanford University in the US has developed a benchmark for machine learning in chemistry. By providing a consistent way to test different techniques across a range of chemical data, it aims to accelerate the growth of this new type of scientific problem-solving.

Source: Royal Society of Chemistry
MoleculeNet curates multiple public datasets, establishes metrics for evaluation, and offers high quality open-source implementations of multiple previously proposed molecular featurisation and learning algorithms (released as part of the DeepChem open source library)

Machine learning methods train a computer to efficiently get from raw data to already-known answers. Once the expected results are consistently reproduced, the software is ready to perform the same task with entirely new data. To fairly compare different learning approaches, research groups around the globe need to train and test their methods using a shared set of problems. Reference databases already exist for images and text; MoleculeNet, an extension of the DeepChem project, provides such a benchmark for chemistry.
