New compound class for treating hepatitis C virus

Researchers from Biotica, UK have discovered a new compound class called sangamides with the potential to treat hepatitis C.   Sangamides are amide derivatives of sanglifehrin A – a cyclophilin-binding polyketide natural product.  Non-immunosuppressive analogues of sanglifehrin A are currently under development as hepatitis C virus therapies, but suffer from lengthy synthetic processes, and some adverse affects including drug-drug interactions.

The newly developed sangamides display improved potency and good pharmcokinetic properties that make them potentially suitable for once-a-day oral treatment of chronic hepatitis C infection.  Download the article for the full details:

Current progress in inhibiting Stat5 protein signalling

This mini-review from Patrick Gunning et al. looks at progress made towards inhibiting Stat5, a member of the Stat family of signalling proteins, that is connected to many cancers, including acute myeloid leukemias and prostate cancer.

Areas covered include both direct and indirect inhibition:

  • Bcr/Abl inhibitors
  • FLT3 inhibitors
  • Jak2 inhibitors
  • truncation inhibitors
  • Binding to DNA
  • Disrupting dimerisation

Pyridazine-containing drugs and single-step labelling of a matrix metalloprotease inhibitor on the cover of MedChemComm Issue 10

Two hot articles feature on the cover of MedChemComm this month:

The outside front cover features the review from Camille Wermuth, Prestwick Chemical Inc., France, on the applications of pyridazine scaffolds for medicinal chemistry. This article has featured in our Top 10 lists for the last 3 months, so why not take a look at what everyone else has been reading?

Are pyridazines privileged structures?
Camille G. Wermuth
Med. Chem. Commun., 2011, 2, 935-941

The inside front cover is from Chris Overall and David Perrin, demonstrating a technique for easy production of 18F labelled marimastat, a clinically trialled breast cancer drug, with general applications for PET imaging.

Towards kit-like 18F-labeling of marimastat, a noncovalent inhibitor drug for in vivo PET imaging cancer associated matrix metalloproteases

RSC e-membership launched

This week, the RSC launched a new product, RSC e-membership, allowing anyone to access an electronic version of Chemistry World through a MyRSC account and to enjoy the benefits of electronic networking via this professional online community for £20/year.

Subscribers to this do not benefit from the professional recognition or any of the other many services and discounts available to RSC Members, but it allows chemists from around the world, many already members of another chemical society in their own country, to benefit from the highly-esteemed content in Chemistry World and the networking opportunities offered from MyRSC, which now stands at over 11,000 members. The RSC e-membership also allows subscribers to join a virtual specialist interest group on MyRSC. If you are interested in joining, please visit www.rsc.org/emembership.

Designing CETP inhibitors for prevention of coronary heart disease

Coronary heart disease has been shown to be related to low levels of high-density lipoprotein cholesterol (HDL-C) in blood plasma, and consequently methods of controlling HDL-C levels are sought to reduce the risk of heart disease.  Inhibition of the cholesteryl ester transfer protein (CETP) – the protein that transports cholesteryl esters from high-density lipoprotein (HDL) to low- and very low-density lipoproteins (LDLs and VLDLs) – has shown potential as a therapy.

Tarun Jha and a team from Jadavpur University have performed studies on a series of 2-arylbenzoxazoles to define the structural requirements of a good CETP inhibitor.  The 2D QSAR study using using PCR, PLS and MLR techniques and kNN-MFA 3D QSAR results have generated a pharmacophore that they hope will provide a good scaffold for the design of future potent CETP inhibitors.

Download the paper today to read the details of their findings – it’s free to access until the end of 2011:

Chemometric modeling and pharmacophore mapping in coronary heart disease: 2-arylbenzoxazoles as cholesteryl ester transfer protein inhibitors

Progress on lamellarins

This review article from Mercedes Álvarez and colleagues at The Center for Biomedical Research Network in Bioengineering, Biomaterials and Nanomedicine, Barcelona, have reviewed the recent developments in studies on lamellarins and their analogues.

Lamellarins are a family of marine pyrrole alkaloids, which have attracted interest as anti-tumour agents.  The review encompasses synthetic strategies for total synthesis, structure–activity relationships and studies on mechanisms of biological action, mainly in the context of anti-tumor activity.
