§1.3Sequence and structural notes

Not applicable — a quaternary quinolinium small molecule, not a peptide

A permanently charged quaternary quinolinium cation supplied as a salt, usually the iodide. Its permanent positive charge is pharmacologically consequential: quaternary cations cross membranes poorly, which is directly relevant to a compound whose target is intracellular.

§1.4Assessment status

The Institute assesses 5-amino-1MQ across 3 indications and grades the strongest of them at very low certainty. No human study has been identified.

Nothing published by the Institute is medical advice, a diagnosis, a prescription, a treatment recommendation or a purchasing recommendation. Compounds supplied for research use are not approved for human or veterinary use in any jurisdiction, and a favourable analytical assessment of a supplier is not a statement that any product is safe or effective.
