Sosei Heptares actively participates in the next European Training Network ONCORNET 2.0
By Chris de Graaf | Jun 5, 2019
The EU has awarded 4 million Euros for ITN research programme ONCORNET2.0, which aims to understand and target two oncogenic G protein-coupled receptors (GPCRs) highly expressed in multiple tumors. The consortium will develop new strategies for chemokine receptor modulation and investigate their effects on oncogenic responses, to yield key new knowledge and potential leads for drug development.READ MORE...

Basal forebrain volumes predict circuit specific functional sensitivity to the muscarinic M1 receptor antagonist biperiden on cognition
By Geor Bakker, PhD, Pradeep Nathan PhD, Alex Godwood MSc. | Apr 3, 2019
We recently attended the Alzheimer’s & Parkinson’s Diseases (ADPD) Conference on 29th March in Lisbon, Portugal where we presented data in the session “Huntington’s and Other Neurodegenerative Diseases: Imaging, Biomarkers, Diagnostics”. In a collaboration led by Sosei Heptares, with the Amsterdam University Medical Centres and Maastricht University, we presented our novel findings in a poster showing that the basal forebrain nuclei volumes can sensitively predict circuitry specific effects of M1 receptor antagonist biperiden on cognition. This work forms an important part of the goals of the Neuroscience Experimental Medicine group to develop novel biomarkers that could define optimal treatment response as well as support patient stratification into clinical trials for drugs in development at Sosei HeptaresREAD MORE...

Structure-Based Drug Discovery of G protein-coupled receptors (GPCRs)
By Kirstie Bennett | Aug 29, 2018
We attended the 15th Meeting of the Asian-Pacific Society for Neurochemistry, held in August 27-29, 2018 in Macau, China. The presentation was focussed around our candidate compound HTL0014242 – a negative allosteric modulator of the metabotropic glutamate 5 receptor (mGlu5). We presented the development of HTL0014242 from hit generation, using a fragment screening approach, to some preliminary efficacy data in the SOD1G93A mouse model of amyotrophic lateral sclerosis (also known as motor neurone disease); data generated through a Sosei Heptares-funded PhD student in Dr Richard Mead’s lab at the Sheffield Institute for Translational Neuroscience.READ MORE...
