Most intriguingly, the amino acid sequences found for the open-chain tetra- and octadepsipeptides were L- O -Val-L-Val-D- O -Leu-D-Ala and (L- O -Val-L-Val-D- O -Leu-D-Ala) 2 and did not match with D- O -Leu-D-Ala-L- O -Val-L-Val and (D- O -Leu-D-Ala-L- O -Val-L-Val) 2 proposed as intermediary depsipeptides in cereulide biosynthesis 8
Intranasal insulin has been investigated in a phase 2 trial in 31 PD participants (NCT04251585) showing acceptable safety but with efficacy data regarding cognitive endpoints yet to be published [164], and a combination of intranasal insulin and glutathione is currently investigated to improve verbal fluency in a phase 2 trial in PD subjects (NCT05266417)
