Description
4-HO-MPT Fumarate is a rare psychedelic tryptamine compound and structural analogue of psilocin and 4-HO-MiPT. This compound is often used in experimental psychopharmacology studies due to its unique binding profile to serotonin receptors, particularly 5-HT2A.
Because of its relationship to naturally occurring compounds such as psilocin (found in psilocybin mushrooms), 4-HO-MPT is of interest to researchers wishing to analyze structural variations within the tryptamine family.
Applications & Usage Scenarios (Laboratory Only)
- Neuropharmacological research: Evaluation of serotonergic activity and binding affinity.
- Structural Activity Research (SAR): Comparative analysis between 4-HO-MiPT, 4-HO-DMT and related derivatives.
- Receptor binding studies: Effectiveness of the molecule on different serotonin receptors.
- Consciousness research (theoretical/lab models): Modeling of altered states in animal models (NOT for human consumption).
