The propionyl grouping at position one of 1P-LSD is said to be metabolized off right away, leaving an NH grouping on the pyrrole ring, in effect giving LSD in vivo.
This is what's known as a pro-drug, a compound which is initially inactive but which is metabolized to the active compound in vivo, a prime example is psilocybin which is a prodrug of psilocin...
Though in this case the 1P may have initial activity before becoming LSD in vivo...
So the 1P becomes LSD in your body, at least this appears to be the case, which would make the compound for all intents and purposes identical to LSD.
Same principle with ALD-52, only the acetyl grouping placed at position one is hydrolysed leaving the needed NH grouping in the pyrrole ring at position 1 to give LSD.
This is from an older thread discussing similar chemical principles...
Quote:anytime you want a prodrug of a tryptamine with an hydroxy group at position 4, you can just substitute the hydroxy grouping with an acetoxy grouping, the acetoxy grouping will become a hydroxy grouping in vivo...at least this seems to be the case.
So, 4-acetoxy-DMT becomes 4-ho-DMT in vivo...4-acetoxy-MET becomes 4-ho-MET in vivo, and so on.
Even with 1-acetyl-LSD this seems to be the case, minus the oxygen because you want an NH grouping at position 1, so it's an acetyl grouping rather than an acetoxy grouping. so the acetyl grouping connected to the nitrogen of the pyrrole ring Returns to a hydrogen atom, restoring the NH grouping of the pyrrole ring, giving LSD in vivo.
With 1-propionyl-LSD, just as above, only using a propionyl grouping at position one of LSD, the propionyl grouping becomes the needed hydrogen atom in vivo to form the NH grouping of the pyrrole ring, giving LSD...
I wonder if 4-propionyloxy-DMT would become 4-ho-DMT in vivo...
