Ribosomally synthesised natural products: a new name for a new year

A large collection of leading researchers in the field of natural product synthesis have come together to propose a communal nomenclature system for the biosynthesis of ribosomally synthesised and posttranslationally modified peptides (RiPPs).

The number of ribosomally synthesised natural products is rapidly increasing, and currently there is no uniform nomenclature being applied across the different compound classes. The classifications currently being used are starting to break down with the increasing number of available genome sequences; the nomenclature used in the various communities investigating subgroups of natural products of ribosomal origin can be confusing, and in some cases even contradictory.

Following on from several discussion groups, the authors of this review (who are working on different classes of RiPPs) present recommendations for a common nomenclature that encompasses all classes, and hope that such a nomenclature will be supported by the rest of the community with the classification of new classes.

In addition to this nomenclature recommendation the authors also present an overview of the current knowledge of the structures and biosynthesis of more than twenty distinct compound classes with examples from bacteria, plants and fungi.

Read this highly informative review today and help sculpt and direct the future of RiPP research.

HOT: Analysing ginseng

Ginseng is one of the world’s most widely used medicinal plants and it is one of the best selling natural products nowadays. Due to its medicinal effects, ginseng has always been an attractive natural product to study and understand.   

However, one of the biggest challenges of ginseng research is the complexity of its chemical constituents and their analysis. Thus, a wide range of analytical methods need to be used to fully characterise these ‘magical components’.

In this very comprehensive review, Lian-Wen Qi, Chong-Zhi Wang and Chun-Su Yuan  illustrate the recent advances in the isolation and analysis of ginseng and highlight its new applications, especially in species authentication, quality assessment and interaction with biological systems.

It is a HOT review because it received very positive comments from the referees and the editorial office.

This will be an excellent article for new-comers in the field as well as a refreshment course for old-timers

Download it now, it’s free to access and learn more about ginseng!

What every chemist should know about plant names

NPR opens 2011 with a very interesting first issue in which a different and original viewpoint by Johannes Erkens is published:

‘In this Viewpoint, I explain why chemists should be aware of the essentials of plant naming, and describe some easy quality checks that can be performed to avoid errors being perpetuated’

This is what he says and that is exactly what he does.

You can read this article free to access until the end of January. Come on! Find out why chemists should know about plant names and comment on it.

Marine Natural Products Review 2011 is published!

Undoubtedly, one of the most popular NPR reviews, the marine natural products  has become a regular review everyone looks forward to.

John Blunt and his co-workers always put together a very comprehensive and detailed review with the latest literature on marine natural products.

This 2011 review highlights the literature for 2009 and describes 1011 new compounds from 352 articles, a small decrease from the number (1065) of compounds reported for 2008. As in previous reviews, the structures are shown only for new compounds, or for previously reported compounds where there has been a structural revision or a newly established stereochemistry.

You can read about all of these marine natural products in the 2011 Advance Review

Marine natural products
John W. Blunt, Brent R. Copp, Murray H. G. Munro, Peter T. Northcote and Michèle R. Prinsep
Nat. Prod. Rep., 2011, Advance Article
DOI: 10.1039/C005001F, Review

And if you missed the most recent reviews on marine natural products you have them here:

Marine natural products 2010

Marine natural products 2009

Marine natural products 2008

Marine natural products 2007

Look out for the Marine Natural Products themed issue that will be published as NPR Issue 2 in 2011.
