The speakers again presented some really exciting and innovative research. Alongside the international speakers Professor Naoto Chatani from Osaka University presented his work on Ni-catalysed functionalization of C-H bonds; OBC Editorial Board member Professor Kenichiro Itami (Nagoya University) talked about how C-H functionalization can be applied to biological and materials problems; and Professor Michinori Suginome presented on chirality-switchable helical macromolecules.

Japan Organic Symposium travels to Tokyo

On to day two of the symposium series, this time at University of Tokyo’s fantastic new auditorium.

The international speakers were joined by a great line-up of researchers from the Tokyo area. First up was Professor Keisuke Suzuki from University of Tokyo, giving a great tour of his research on synthesis of hybrid natural products.

Japan Organic Chemistry Symposia – June 2015

This week the Royal Society of Chemistry is visiting three institutes in Japan for our 2015 Organic Chemistry Symposia. We’ll be at Tohoku University on Monday 1st June, University of Tokyo on Wednesday 3rd and Kyoto University on Friday 5th.

Each symposium will feature speakers from Japanese universities along with three international speakers who will travel to each institute.

The symposia are presented by our journals Organic & Biomolecular Chemistry and Organic Chemistry Frontiers, and supported by ChemComm, Chemical Society Reviews and Chemical Science. We’re very grateful to our hosts -Professor Masahiro Terada in Sendai, Professor Masayuki Inoue in Tokyo and Professor Keiji Maruoka in Kyoto – for their support for these events.

We hope to see you at one of the symposia!

Vaccines for heroin

The number of deaths due to heroin overdoses has severely increased in last decade, and regular consumption of heroin leads to serious health concerns.

Vaccination is one of the emerging choices among heroin rehabilitation therapies. In general, these vaccines contain heroin-like hapten as a pharmacophore that acts as an antagonist. This antagonist has high affinity for heroin receptors but does not activate them, hence reverses the effects of heroin. Because of inherent chemical instability, when entered in to bloodstream these anti-heroin drugs rapidly metabolise into several by-products, which makes development of effective vaccines against heroin particularly challenging.

Recently an American research group at National Institute on Drug Abuse (NIDA) lead by Professor Kenner Rice has reported the synthesis and immunological evaluation for a series of haptens.

The team has emphasised the hydrolytic stability of hapten scaffolds and envisioned that hapten with amido groups at both the C3 and C6 positions should be more stable than a hapten with an ester in one of those positions. Insertion of a 3-amino group and the construction of a C-6α-(2-oxo-propyl) group stereoselectively was the challenging task towards the synthesis of designed hapten derivatives. The group has tackled the synthetic hurdle by adopting convergent synthesis approach and validating the stereochemistry by single X ray crystallography.

Furthermore, in vivo Immunological studies of all three new synthetic haptens reveals that one derivative DiAmHap (3) is chemically more stable and better candidate for a heroin vaccine than 6-PrOxyHap (1) and DiPrOxyHap (2). This work is a very positive step towards the development of vaccines for heroin abuse.

Amino acids: fluorescensors for mercury ions

Many human activities have been responsible for heavy metal poisoning in recent years, Mercury (Hg) poisoning being one of them. Mercury occurs in several forms and even trace concentrations of mercury ions in crops, fish or the human body are enough to produce potentially toxic effects to vital organs. Mercury poisoning can lead to several diseases including Acrodynia (also known as the pink disease), the Hunter-Russell syndrome and the Minamata disease.

Selective detection of mercury, particularly in aqueous media, has been a key area for analytical chemists, since traditional analytical techniques for mercury detection are time consuming, laborious and involve expensive instrumentation. In this work, Korean researcher Keun-Hyeung Lee and co-workers have developed a pair of very sensitive amino acid based fluorescence-ON probes for the exclusive detection of mercury ions in aqueous solution.

The team has combined the fluorescence properties of pyrene and Hg(II) binding ability of tyrosine residues for the design and synthesis of two novel fluorescensors. Both newly-synthesised probes show emission maxima at 386 and 400 nm in the absence of Hg(II) ion. Upon titration with Hg(II) ions, both probes show exponential fluorescence enhancement and display a remarkable red shift (90-100 nm) emission. These probes are also highly selective for mercury ions in the presence of a range of other metal ions and are effective in aqueous solutions.

The team further clarifies the binding mode of these sensors and the coordination of the metal ion. This method can be implemented for rapid and quantitative detection of Hg(II) from various polluted water sources. This work also underscores the unconventional use of an amino acid as a chemosensor.

Introducing two new article types for Organic & Biomolecular Chemistry

OBC is introducing two new review article types: Reviews and Perspectives. These replace previous review article types and offer our authors and readers an even broader range of reviews, opinions and commentaries on the latest developments in organic chemistry and chemical biology.

Reviews
OBC Reviews are short, easy-to-read review articles covering current areas of interest to the OBC audience. Flexible in style, they give a concise and critical appraisal of recent advances in an established field or a new area of research.

Authors are encouraged to include their own views on developments, trends and future directions, with speculation about the future potential of the field particularly encouraged. Reviews are typically 6-12 pages in length. 

Reviews replace the previous Perspective and Emerging Area article types. While there is a change in name, the flexibility and breadth of style and content remain very much the same. Authors can write on established topics of current interest or emerging topics that are in the early stages of development. All of these styles will be consolidated under the Review name.*

Perspectives
OBC Perspectives are changing. These are now a new article style which will highlight pieces of exciting, recently-published research. Written by the authors of the original research, Perspectives will give a personal viewpoint on the topic, discussing their research in the wider context of the field and the future potential for the area.

Perspectives are designed to be short (2-4 printed pages) articles, briefly covering:

  • The background to the research area; its importance and previous developments
  • A summary of the key aspects of the research paper(s) recently published by the author
  • An outlook on future progression of the field, including how the author’s research could impact that

 Each Perspective will focus on just one or two recently-published research papers by the author. They will not cover large aspects of an author’s previous research.

 For guidelines on the new article types please click on the following links: Reviews | Perspectives.

*As a result of these changes the Emerging Area article type has been discontinued. Any emerging area style article should now be submitted under the Review article type.
