Dr. GPCR x Celtarys Reseach

Empowering medicinal biochemists
Celtarys empowers medicinal biochemists by providing innovative fluorescent probes that de-risk the pre-clinical drug discovery phase. Our proprietary conjugation technology and unparalleled scientific expertise ensure researchers can confidently advance their projects with greater precision and reliability.


About Celtarys Research
Celtarys Research develops and commercializes new chemical tools to spread the use of fluorescence-based methods in the pre-clinical phase of drug discovery. Our proprietary chemical conjugation technology allows us to develop in a competitive manner and short time (<3 months) customized fluorescent ligands with optimal pharmacological and photophysical properties for any druggable target.
We have a catalogue of over 30 fluorescent ligands for different families of GPCRs, including adenosine, dopamine, serotonin, cannabinoid and muscarinic receptors. We also offer our expertise in the form of custom development services, where we tackle challenging targets and synthesize probes with the most suitable properties for your needs.
