Composition of matter and methods of use claims encompass EB-373, Enveric’s new chemical entity psilocin prodrug being developed for the treatment of anxiety disorder

Enveric Biosciences (NASDAQ: ENVB) (“Enveric” or the “Company”), a biotechnology company dedicated to the development of novel neuroplastogenic small-molecule therapeutics for the treatment of anxiety, depression, and addiction disorders, today announced that the United States Patent and Trademark Office issued U.S. Patent No. 11,707,441, titled “C4-Carbonothioate-substituted Tryptamine Derivatives and Methods of Using,” pertaining to the Company’s lead candidate EB-373, a psilocin prodrug being developed for the treatment of anxiety disorder.

This new patent, issued July 25, 2023, provides Enveric with intellectual property rights for compositions and methods for tryptamine-derived prodrugs utilizing C4-substituted tryptamine derivatives and C4-carbonothiate-substituted tryptamine derivatives. These enhancements to the tryptamine chemical structure are designed to potentially elicit a more rapid onset of action, more controlled therapeutic effect, and reduced gastrointestinal side-effects compared to conventional psilocin prodrugs, such as psilocybin. Enveric’s lead product candidate, EB-373, is a new chemical entity (NCE) psilocin prodrug being developed for the treatment of anxiety disorder.

“This U.S. patent issuance is a significant milestone for Enveric in our effort to advance novel tryptamine compounds that are unique and differentiated from other psilocin-based candidates being developed for the treatment of mental health disorders,” said Joseph Tucker, Ph.D., Director and CEO of Enveric. “Several tryptamines including psilocybin, DMT and 5MeO-DMT have shown therapeutic benefit for the treatment of numerous psychiatric diseases. However, these compounds are not optimized for induction of consistent and predictable neuroplasticity, resulting in intense psychedelic experiences that are a barrier to widespread therapeutic application. With EB-373 and our EVM201 and EVM301 Series, we are focused on creating innovative, non-obvious alterations to related compounds that are intended to generate neuroplastic changes which will yield efficacious treatments for critical mental health disorders, while also minimizing unwanted side effects and safety concerns.”

“Enhancing the IP protection for our technologies is a key growth driver for Enveric, and we have recently received multiple notices of allowance from the USPTO for EB-373 and our EVM201 and EVM301 Series. We now anticipate several of these applications to result in U.S. patents over the coming months,” said Tucker.

About EB-373

Enveric’s lead drug candidate, EB-373, is a New Chemical Entity (NCE), designed as a next-generation proprietary psilocin prodrug and developed leveraging the company’s Psybrary™ drug discovery platform to target anxiety disorders. In preclinical studies, EB-373 displayed efficient prodrug parameters, demonstrating rapid and complete generation of psilocin both in vitro and when orally administered. Mice treated with EB-373 demonstrate dose-dependent induction of head twitch response characteristic of psilocin. In the Marble Burying Test, an animal behavioral model of anxiety, EB-373 was able to promptly rescue the enhanced rate of marble burying observed in chronically stressed mice, in line with the control baseline behavior and with long-term anxiolytic benefits lasting the length of the study, 7 days post-dose.
