GtoPdb Ligand ID: 13141

Compound class: Natural product or derivative
Comment: Tetrahydroharmine is a plant-derived β-carboline alkaloid that is a component of the psychoactive drink Ayahuasca, that is traditionally brewed by indigenous cultures in the Amazon. It is one of the harmala alkaloids produced by plants such as Banisteriopsis caapi and Peganum harmala. Pharmacologically tetrahydroharmine acts to prevent the breakdown of Ayahuasca's principal hallucinogenic substance dimethyltryptamine (DMT) by reversibly inhibiting monoamine oxidase A (MAO-A) [1].

2D Structure

An image of the ligand's 2D structure. For small molecules with SMILES these are drawn using the NCI/CADD Chemical Identifier Resolver. Click on the image to access the chemical structure search tool with the ligand pre-loaded in the structure editor. For other types of ligands, e.g. longer nucleotides and peptides, a manually drawn representation of the molecule may be provided.

SMILES / InChI / InChIKey

SMILES (Simplified Molecular Input Line Entry Specification) A specification for unambiguously describing the structure of chemical molecules using short ASCII strings. Canonical SMILES specify a unique representation of the 2D structure without chiral or isotopic specifications. Isomeric SMILES include chiral specification and isotopes.

Standard InChI (IUPAC International Chemical Identifier) and InChIKey InChI is a non-proprietary, standard, textual identifier for chemical substances designed to facilitate linking of information and database searching. An InChIKey is a simplified version of a full InChI, designed for easier web searching.
