It means that PRL-8-53 can degrade into its metabolite desmethyl-PRL-8-53 which the authors thought might have been the main contributor to the nootropic effects of PRL-8-53. That's good. Indicates a longer half-life for the compound and its metabolite.Not sure, we're focusing on PRL-8-53. PRL-8-147 hasn't been tested on humans yet.
I am not sure what the reference to PRL 147 has to do with it, redan. I know we're talking re 53 and the study was re 53. The note i was referring to was at the bottom of the last page of the full text and reads:
"NOTE ADDED IN PROOF
Following completion of this study it was found that the particular
lot of PRL-8-53 that had been used contained a small amount of
the desmethyl compound as admixture, which may also have contributed
to the observed effects. However, since this compound is
considered a metabolite of the parent compound (8-53), its
presence should not detract from the findings."
what does this mean?
