Discovery is in our nature

Introducing a new generation of psychedelic-inspired medicines

We have created a vast library of patentable and highly active new chemical entities (NCEs) that are designed to target serotonin receptors in a specific manner to enable the treatment of multiple neurological diseases and disorders.

PsiloSterics | Who We Are

Moving beyond the First-Gen approach

First-generation psychedelic companies are largely focused on “repackaging” old drugs that were initially discovered by scientists more than 30 years ago, resulting in many companies pursuing the advancement of known hallucinogenic drugs that require the presence of a medical professional when administered to patients.

Our next-gen approach: Pseudo-psychedelic therapeutics

We have designed and synthesized novel, non-hallucinogenic serotonin receptor agonists that reduce or eliminate the cardiotoxic effects commonly observed with known hallucinogenic drugs, allowing for long-term, unsupervised administration to patients on a daily or weekly basis. This design approach has guided us to over a dozen proprietary, patent-pending molecular scaffolds covering thousands of novel therapeutic compounds that can be tailored to target a variety of neurological disorders.

Collaborating with some of the top academic groups in the industry, our top NCE candidates are being advanced through a battery of in vitro and in vivo pre-clinical studies to enable lead candidate selection and optimization.

Our Process


By combining proprietary SAR analytics, medicinal chemistry analyses, and exhaustive prior art research, we design and synthesize novel molecular scaffolds.


Using in silico screening and molecular modeling, we narrow our focus to refine and select scaffolds with the highest likelihood of replicating – or exceeding – the therapeutic benefits of traditional psychedelic compounds, while reducing or eliminating the hallucinogenic and cardiotoxic aspects of those drugs.

Patent Filing

We rigorously examine the IP landscape to determine patentability and freedom to operate for our novel scaffolds and their related NCE candidates. So far, this has resulted in the preparation and filing of more than 30 patent applications, with many of those applications individually disclosing 500+ novel compounds.

NCE synthesis

Leveraging our in-house laboratory and 50+ years of combined medicinal chemistry expertise, we synthesize, prepare and characterize our NCEs for in vitro and in vivo studies.

pre-clinical studies

Once identified as a potential lead, our top NCE candidates are advanced into our pre-clinical program with leading academic collaborators for optimization and indication-specific studies.

The Opportunity Ahead

Psychedelic drugs have the potential to address multiple indications affecting large population groups that make up extremely sizable markets. However, many First-Gen natural and synthetic analogs are not optimized for continual therapeutic use. Our novel therapeutics are designed without the hallucinogenic and other side effects that have prevented existing psychedelics from being widely adopted for addressing the current global epidemic of mental health disorders.

Unlike naturally-occurring or synthetic serotonergic agents previously developed, our new generation of NCEs are novel and patentable, allowing us to avoid the vast and complicated IP landscape created by First-Gen companies. PsiloSterics exclusively owns all intellectual property rights associated with its proprietary scaffolds and NCEs.

Our Team

Chief Executive Officer
Allen C. Barbieri
Allen brings a wealth of experience to PsiloSterics. In addition to serving as our CEO, Allen is currently a member of the Board of Directors of CareTrust REIT (NASDAQ: CTRE), a $2 billion healthcare REIT, and as a Director and the Executive Vice Chairman of Biomerica, Inc., a biomedical enterprise focused on development of revolutionary therapeutic treatments for gastrointestinal diseases, such as IBS, and for depression and other diseases that are triggered by immunoreactivity. Allen helped manage Biomerica’s recently completed clinical trial for an IBS therapy that was conducted at Mayo Clinic, Harvard and other leading institutions.

Previously, Allen served as the Chairman and Chief Executive Officer of BioSynthetic Technologies, a specialty chemical company that created novel, bio-based synthetic compounds having a variety of applications in the industrial, personal care, and pharmaceutical sectors. While at BioSynthetic, Allen raised $65 million from venture partners including BP, Monsanto and Evonik Industries. Allen led a talented team of chemists that invented, scale-manufactured, and contract-validated dozens of new compounds, which led to the issuance of more than 150 patents. Prior to that, Mr. Barbieri served as Chief Executive Officer of Lancer Orthodontics, Inc., a manufacturer of orthodontic devices with operations in Mexico and San Diego. Before this, Allen served as President and Chief Financial Officer of BUY.COM, a large internet retailer financed with over $300 million in venture capital from Soft Bank. Allen has also served as the President and Chief Executive Officer of Pacific National Bank, President of Capital Bancorp, a commercial bank holding company, Chief Financial Officer of First Federal Bank, and as an Investment Banking Associate of Merrill Lynch Capital Markets in New York.

Allen holds an M.B.A. Degree from the MIT - Sloan School of Management, and a Bachelor’s Degree in Finance from Brigham Young University.
Chief Technical Officer
David Gilles
David Gilles is the founding member of PsiloSterics. He started his career as the Director of R&D at BioSynthetic Technologies. While at BioSynthetic, David developed novel molecular architectures and scaled the synthesis of new compounds that remain in commercial production today. In particular, David oversaw the design and enantioselective GMP production of the company’s proprietary 9- and 10-PAHSA analogs, which are currently in pre-clinical evaluation at Harvard Medical School as potent anti-inflammatory and antidiabetic agents. The work by David and his team was critical to the success of Biosynthetic, leading to the company’s acquisition by The Heritage Group in 2018.

David also brings a wealth of expertise in designing, synthesizing, and characterizing psychoactive drugs. He spent nearly 10 years as a student and graduate researcher at the University of Hawaii creating novel cannabinoid analogs, prodrugs and targeted covalent inhibitors. Notably, his research played a key role in the elucidation of the cannabinoid receptor binding pocket and the first crystal structure of Cannabinoid Receptor 1, the principal target of Δ9-tetrahydrocannabinol.

David holds a B.S. in Chemistry and an M.S. in Organic Chemistry from the University of Hawaii.
