SKU: N/A Category:

N-propyl-L-tryptophan is an amino acid derivative. It is closely related to L-abrine (N-methyl-L-tryptophan), and more distantly related to N,N-dimethyl-L-tryptophan (L-DMTP).

N-propyl-L-tryptophan also bears structural resemblance to NPT (N-propyltryptamine). It is unknown if it were to act as a prodrug for NPT, or if it even has any bioavailability (that is, if it can pass the blood-brain barrier).


This compound is NOT for human consumption and is available for research purposes only. Available as the free zwitterion.
