NEWS RELEASE

LEXSTON INITIATES RESEARCH AND DEVELOPMENT PROJECT

USING PSYCHEDELIC COMPOUND 5-Me0-DMT

Vancouver, British Columbia, September 23, 2021. Lexston Life Sciences Corp. (CSE: LEXT) (the

“Company” or “Lexston”) is pleased to announce that the company’s scientific research and development

division led by Chief Science Officer, Dr. Philippe Henry, has begun work on its tryptamine pipeline with

an initial focus on 5 -Methoxy-N, N-dimethyltryptamine (5-MeO-DMT) at its newly acquired Zen alytic

Laboratories.

With confirmation from Health Canada’s Controlled Substances Directorate to proceed with

characterization work on the target molecule, 5 -MeO-DMT, Lexston’s scientists have moved ahead with

its plans to develop methods for the identification and quantification of this target tryptamine. The

Company has also successfully developed a High Pressure Liquid Chromatography (HPLC) assay for the

determination and purity of 5-MeO-DMT, thus paving the way for future product development activities.

Additionally, it has successfully collected Near- Infrared spectra (NIRs) from the purified substance to

develop a portable rapid technique for the identification and quantification of tryptamine formulations at

the point-of-care.

The Company is explorin g different naturally derived botanical sources of 5 -MeO-DMT, the use of

different solvents and delivery systems for a formulation of a sub -psychoactive dosage . Based on its

neuro-vasocontraction abilities this formulation will be used in conj unction with clinical partners

specifically targeted for the alternative treatment of migraines and cluster headaches.

In support of clinical applications, the Lexston team is also collecting serotonin and other receptor affinity

data for 5 -MeO-DMT, its metabolites and other closely related tryptamines. 5-MeO-DMT possesses

unique pharmacodynamic and pharmacokinetic properties imparted by its specificity for serotonin

receptors 5HT-1a,7,6,1d and dopamine D1. Unravelling the mechanism underlying the mode of action of

this tryptamine is expected to shed light on potential novel treatments for major depressive disorders and

addiction.

“We believe that the 5 -MeO pathway is fundamental to the development of multiple novel treatments

and the activation of a tryptamine production pipeline early in the upcoming psychedelic trend is vital to

accelerating the access to treatment with these potentially life altering compounds.” stated Graeme Staley,

Director of Lexston.
