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

Poster prize winner at the 16th SCI/RSC Medicinal Chemistry Symposium

I am delighted to report that Dr Martine Keenan from Epichem Pty Ltd (Murdoch, Australia) was the winner of the MedChemComm poster prize at the recent 16th SCI/RSC Medicinal Chemistry Symposium that took place at Churchill College in Cambridge, UK, from 11 to 14 September.

The symposium was jointly organised by the Society of Chemical Industry and the Royal Society of Chemistry, and gave a splendid overview of some of the new strategies in Medicinal Chemistry and Pharmaceutical Research.

Martine’s winning poster entitled ‘Collaborative drug discovery for neglected diseases: novel compounds for the treatment of Chagas Disease’ presents the identification and development of two novel compound series active against the intracellular protozoan parasite Trypanosoma cruzi, the causative agent of the Chagas disease. Endemic in 21 countries across Latin America, the Chagas disease is responsible for more deaths in this region than Malaria, or any other parasite-born disease, and is currently spreading to developed countries including Australia, USA, Japan or Spain. This award winning work is the result of a collaborative drug discovery consortium established by not-for-profit, drug research and development organisation Drugs for Neglected Diseases initiative (DNDi).

Congratulations again to Martine on her award-winning work and to the collaborative drug delivery consortium for their active research on neglected diseases.

Highly selective agonist for the metabotropic glutamate receptor mGluR2

Work from this international collaboration spanning Denmark, Italy, Sweden and the USA brings insights into the synthesis and characterization of a selective agonist for the metabotropic glutamate receptor mGluR2, a potential therapeutic target for neurologic and psychiatric diseases.

The team’s approach to the agonist design was to induce selectivity for mGluR2 over other family members via imposing conformational rigidity into the carbon skeleton of the Glu analogues. This resulted in an increase of selectivity of at least two orders of magnitude compared to homologous mGluR3 as well as mGluR1, 4, 5, 7.
