Is o-Vanillin legal in Australia?

A natural aldehyde related to vanillin that cleared senescent cells from human spinal disc tissue in the laboratory and reduced pain behaviour in a mouse model of back pain. It has never been given to a person in a trial.

o-Vanillin is an isomer of vanillin, the compound that gives vanilla its smell, and almost everything known about it as a senolytic comes from one research programme at McGill University focused on a specific problem: the degenerating intervertebral disc. The rationale is unusually concrete.

Mechanism: o-Vanillin selectively triggers death in senescent cells while leaving non-senescent cells largely intact, and separately reduces the secretion of inflammatory SASP factors, so it behaves as both a senolytic and a senomorphic in the same tissue. The reported molecular routes are the Nrf2 antioxidant response and NF-kB inflammatory signalling, with work in disc cells also implicating Toll-like receptor 2, which is highly expressed on senescent disc cells and whose activation induces senescence in the first place.

Regulatory history: Not approved as a drug for any indication. o-Vanillin is a known chemical used as a flavour and fragrance intermediate and available as a laboratory reagent, which is not the same as being a permitted supplement ingredient or an approved medicine. It is not in any registered human trial as a senolytic.

Registers or lists therapeutic goods on the ARTG and schedules substances in the Poisons Standard. Many peptides are Schedule 4 (prescription only), so possession without a prescription and personal importation are restricted even when no product is registered.

The classification above is the The Longevity Archive reading of Therapeutic Goods Administration listings for o-Vanillin 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.
