Cybin Announces Publication of Research Manuscript in the Journal of Medicinal Chemistry

Cybin Inc. (NYSE American:CYBN) (Cboe CA:CYBN) (“Cybin” or the “Company”), a clinical-stage biopharmaceutical company committed to revolutionizing mental healthcare by developing new and innovative next-generation psychedelic-based treatment options, today announced that its research manuscript, entitled “Synthesis and Structure-Activity Relationships of 2,5-dimethoxy-4-substituted phenethylamines and the discovery of CYB210010: A potent, orally bioavailable and long-acting serotonin 5-HT₂ receptor agonist,” has been published in the Journal of Medicinal Chemistry, a prestigious bi-weekly peer-reviewed publication.

“We are delighted that our research on phenethylamine serotonin 5-HT₂ receptor agonists was published in this important journal,” said Doug Drysdale, Chief Executive Officer of Cybin. “This study is an example of our expanding scope of innovative development work beyond our clinical tryptamine programs. This publication is a testament not only to our scientific leadership in the field of 5-HT₂ receptor agonists, the receptor family believed to mediate the therapeutic effects of classic psychedelics, but also to the depth and breadth of our expertise as we continue to advance the study of the role of next-generation psychedelic-based treatment options for mental health and neurological disorders.”

“In the past decade, there has been a revival of interest in serotonin (5-HT)-based psychedelics as pharmacotherapeutics for neuropsychiatric disorders,” said Geoff Varty, Ph.D., Head of R&D of Cybin. “Given the clinical potential of 2C-X phenethylamines, our studies explored the SARs of a broad range of 2C-X analogs, focusing on 4-thio derivatives, to identify novel 5-HT₂ receptor ligands with unique pharmacodynamic (“PD”) and pharmacokinetic (“PK”) properties. We synthesized 39 proprietary 4-substituted-2,5-dimethoxyphenethylamines and these phenethylamines were profiled for their ability to interact with the serotonin system and to induce psychedelic-like effects in preclinical models. This research led to the discovery of CYB210010, a potent and long-acting serotonin 5-HT₂ receptor agonist with favorable PK and PD properties,” concluded Dr. Varty.
