About one quarter of the mixture is small peptides with this neurotrophic-like activity, said to resemble BDNF, GDNF, NGF, and CNTF
2 PMC NAD+ Metabolism ReviewComprehensive review of NAD+ metabolism, mitochondrial function and aging
Key pharmacokinetic parameters observed in animal models include: Plasma half-life approximately 20-30 minutes in rat models Rapid hepatic metabolism through aminopeptidase activity Complete clearance from circulation within approximately 10 minutes using sensitive detection methods in some studies Pharmacodynamic effects persist considerably longer than the plasma half-life would predict, suggesting either active metabolite contributions or persistent receptor-mediated signaling The dipeptide GP and tripeptide PGP, products of Selank biodegradation, are themselves reported to have independent biological activity, potentially contributing to the overall pharmacodynamic profile after parent peptide clearance
