Selective OXER1 Antagonist
Our Selective Oxo-eicosanoid receptor 1 (OXER1) Antagonist Program
We are developing a first-in-class, oral, selective OXER1 antagonist candidate. OXER1 is a G protein-coupled receptor (GPCR) that is highly selective for 5-Oxo-eicosatetraenoic acid (5-oxo-ETE), one of the most potent human eosinophil chemo-attractants. Migration of eosinophils to body sites including the lungs and intestines is mediated by eosinophil chemo-attractants such as 5-oxo-ETE. Eosinophils play a key role in Type 2 inflammation-driven diseases, including respiratory diseases and gastro-intestinal diseases.
Eosinophilic-related diseases represent a significant area of unmet need in global health. Several biologics have been approved for the treatment of eosinophil-related diseases, with combined drug sales in 2018 exceeding USD$ 3 Billion. Compared to approved biologics, small molecule OXE receptor antagonists may offer a promising and potentially more cost-effective option for treatment of eosinophilic-driven disorders.
Our Selective OXER1 Antagonist Program
The OXER1 antagonist program is based on the research of Dr. William Powell, Professor Emeritus in the Department of Medicine at McGill University, working in collaboration with Dr. Joshua Rokach of the Florida Institute of Technology. Dr. Powell serves as an advisor to Liminal BioSciences on the OXER1 antagonist program.
In addition to our experienced in-house medicinal chemistry group, we have a strong understanding and well-established, in-house expertise in GPCR biology.
Our OXER1 antagonist program is currently at the pre-clinical stage.
