This compound caught my eye a while back because of a fruit fly study:
acute administration of the chemical chaperone sodium 4-phenylbutyrate (PBA) reduces ER stress and ameliorates age-associated sleep changes in Drosophila
PBA consolidates both baseline and recovery sleep in aging flies. The behavioral modifications of PBA are linked to its suppression of ER stress.

Does anyone have a source they can recommend for sodium 4-phenylbutyrate?
