MedChemComm delighted to meet authors!

18 Apr 2011

The Royal Society of Chemistry was present in Anaheim for the ACS Spring 2011 National Meeting and Exposition last March. Very hectic few days full of Journal celebrations, product demos and workshops.

We were very happy to hear that one of our MedChemComm authors, Jose Medina Franco, paid the RSC booth a visit.
Here you can see him with a copy of MedChemComm Issue 1, where his article was published.

Thanks to Jose for dropping by! You can now read his article, which is free to access here.

Structure–activity relationships of benzimidazole derivatives as antiparasitic agents: Dual activity-difference (DAD) maps
Jaime Pérez-Villanueva, Radleigh Santos, Alicia Hernández-Campos, Marc A. Giulianotti, Rafael Castillo and Jose L. Medina-Franco
Med. Chem. Commun., 2011, 2, 44-49
DOI: 10.1039/C0MD00159G

If you want to find out where we are going this year and you want to come and meet us, like Jose did, we would love to hear from you. These are the list of conferences we are planning to go to:

Lakeland Heterocyclic meeting, May – Grasmere, UK
ACS National Organic Symposium – 5th – 9th June – Princeton, US
Frontiers in Medicinal Chemistry Meeting: Emerging Targets, Novel Candidates and Innovative Strategies- 19th-21st July – Stockholm, Sweden

HOT article: potential new G-quadruplex ligands

12 Apr 2011

Finding ligands capable of stabilising G-quadruplex DNA structures has been a hot topic in medicinal chemistry for a number of years now, due to their potential as anti-cancer treatments. But despite intensive research G-quadruplex ligands are yet to appear on the drug market-due to various problems with toxicity and efficacy-requiring the investigation of new, effective compounds.

Adam Le Gresley and colleagues from Kingston University have therefore investigated 8 anthracene-9-monoacrylamides and anthracen-9,10-bisacrylamides, which fit the criteria that has been identified for successful G-quadruplex binding. They were surprised that neither the synthesis nor biological evaluation of their chosen diacrylamides had previously been reported, and so characterise them fully here. They found that one class of ligand tested possesses anti-cancer activity, based on promotion of quadruplex DNA formation observed in solution by NMR, coupled with ‘compelling’ fluorescence data and initial biological testing. The group are now undertaking further investigations to better understand the activity of the diacrylamides.

Read more about this new class of potential G-quadruplex ligands – the paper is currently free to access:

RSC Residential School in Medicinal Chemistry – book your place now!

01 Apr 2011

Don’t miss out on early bird registration for the RSC’s Residential School in Medicinal Chemistry, being held this year at Burleigh Court Conference Centre at Loughborough University on 4-8 July 2011.

For over 30 years this course has been regarded as the pre-eminent industry training course for medicinal chemists. It brings together cross-industry and cross-discipline practitioners to provide lectures, tutorials, workshops and case-studies illustrating modern drug discovery. This provides an excellent training opportunity for young medicinal chemists. The course also provides a refresher for those who are more experienced but wish to expand their knowledge or offers an introduction to drug design thinking for any scientist working in cross-functional discovery teams. In addition, the opportunity to network with and learn from highly experienced medicinal chemistry professionals is the unique feature of this training school. For the training content and list of course tutors, please see www.rsc.org/medchemtraining

The early bird registration for this event will close on 1st April (although standard registration will remain open until 13th May). Places can be secured quickly and simply via the online booking system. Please note that previous courses have been oversubscribed so please encourage interested parties to register early to be sure of their place!

HOT Article: A step forward in the fight against cancer

01 Apr 2011

Novel water soluble bis(1,10-phenanthroline)octanedioate Cu²⁺ and Mn²⁺ complexes synthesised by researchers in Ireland and the US show extremely high cytotoxicity, encouraging cytoselectivity against cancer cells.

Mononuclear [Cu(phen)₂(phthalate)] complexes have been shown to display excellent chemotherapeutic potential against colon, breast and prostate cancer lines, but their water solubility is poor making them difficult to deliver in the body. This inspired Andrew Kellett, Michael Devereux and colleagues to build upon the most active chemotherapeutic agents in this class of compounds and develop more potent water soluble versions.

Both complexes displayed greater in vivo drug tolerance compared to cisplatin, a commonly used chemotherapy drug, when examined using the insect Galleria mellonella.
