What SG1002 is
Hydrogen sulfide is required for the lifespan benefits of dietary restriction in several species, so a donor was an unusually well-motivated candidate. It failed at three different starting ages.
The case for testing this was among the strongest in the whole programme. Hydrogen sulfide is a gaseous signalling molecule, and work across yeast, worms, flies and mice found it necessary for the lifespan and stress-resistance benefits of dietary restriction.
Mechanism: An orally bioavailable prodrug that releases hydrogen sulfide, raising plasma sulfide and thiosulfate. Hydrogen sulfide signals largely through persulfidation, adding a sulfur to reactive cysteine residues on target proteins, which modifies their activity.
Regulatory history: Investigational. Not approved for any indication.
How MHRA treats this kind of product
Licenses medicines for the UK market. A compound without a marketing authorisation is an unlicensed medicine, which can only lawfully be supplied for human use through a prescriber under the specials scheme, not sold as a research product.
The classification above is the The Longevity Archive reading of Medicines and Healthcare products Regulatory Agency listings for SG1002 at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
