Description
BACKGROUND OF THE INVENTION

N,N-dimethyltryptamine (DMT) is a naturally occurring compound found in numerous plant species and botanical preparations, such as the hallucinogenic infusion known as ayahuasca, and classified as a classic serotonergic psychedelic that induces intense modifications in perception, emotion, and cognition in humans. At higher doses, DMT has a rapid onset, intense psychedelic effects, and a relatively short duration of action with an estimated half-life of less than fifteen minutes. Like other hallucinogens in the tryptamine family, DMT binds to serotonin receptors to produce euphoria and psychedelic effects. Unfortunately, DMT is metabolically unstable and is readily converted by monoamine oxidases (MAO's) to indoleacetic acid and N-oxidation metabolites resulting in poor oral bioavailability.


Serotonergic psychedelics have also demonstrated promising antidepressant, anxiolytic, and anti-addictive properties.


There remains a need for improved prodrugs of tryptamines, such as N,N-dimethyltryptamine (DMT).

Compounds

The present disclosure provides compounds that are prodrugs of tryptamines and related scaffolds, for example N,N-dimethyltryptamine (DMT) as well as pharmaceutical compositions thereof.


DMT is metabolically unstable and is readily converted by monoamine oxidases (MAO's) to indoleacetic acid and N-oxidation metabolites resulting in poor oral bioavailability. In embodiments, the compounds of the present disclosure allow for the controlled release of DMT. Advantages of compounds of the present disclosure may include increased metabolic stability, increased absorption, decreased maximal plasma concentrations of parent drug DMT over time, and less frequent dosing. In embodiments, compounds of the present disclosure prevent or inhibit N-oxidation to promote oral bioavailability and increased exposure.


In embodiments, the DMT compounds of the present disclosure comprise a phosphate moiety, a phosphonate moiety, or a derivate thereof. Without being bound by theory such compounds may for example, increase bioavailability by virtue of active transport of the prodrug in the small intestine by high-capacity nutrient transporters, including mono-carboxylate transporter-1 (MCT-1). The DMT prodrugs disclosed herein may also reduce abuse potential by preventing absorption by snorting or insufflation.

Illustration of the Prodrug Strategy:

Compound 1 was synthesized as part of a novel prodrug strategy for improving the water solubility of tertiary amine-containing drugs. As shown in the above scheme, tertiary amine DMT (parent) was converted in two-step reaction to the polar Intermediate Prodrug 1.


Intermediate Prodrug 1 releases the parent DMT in vivo through a two-step bio-reversion process. The rate determining first step is via an enzymatic process, where prodrug bio-reversion involves a phosphatase-catalyzed dephosphorylation to give the resultant hydroxymethyl quaternary ammonium intermediate and inorganic phosphate. The second step involves conversion of the hydroxymethyl quaternary ammonium intermediate chemically to DMT and formaldehyde at physiological pH.


Chemical and plasma stability of prodrug Compound 1 was evaluated and the results enumerated in Table 7 and Table 8, respectively. PK studies of prodrug Compound 1 and metabolite (VLS-02-23-10) in mice were also conducted and both plasma exposure and brain exposure were analyzed as shown in FIGS. 1A-1C and FIGS. 2A-2B, respectively.
