The active group in its molecular structure is the sulfhydryl group (-SH) on the cysteine residue
However, the clinical application of SIN is limited by its poor pharmacokinetic properties, such as low oral bioavailability and a short half-life

Volkova A et al., 2016 [PubMed] Key Areas of Research: Molecular Tuftsin receptor binding characterization, GABAergic gene expression profiling, peptide structural stability assays in biological matrices, angiotensin-converting enzyme interaction mapping, enzymatic cleavage resistance characterization Cellular / Neurochemical GABAergic signaling pathway characterization, inhibitory neurotransmission parameter assessment, neuroblastoma cell line gene expression profiling, GABA receptor interaction modeling, anxiolytic-relevant receptor system characterization in preclinical settings Systemic (Preclinical) Behavioral parameter measurement in anxiety-relevant preclinical models, cytokine pathway modulation monitoring, neuroimmune axis interaction characterization, inhibitory signaling system profiling in controlled investigational settings Together, these findings suggest broad experimental potential for Selank across GABAergic neurotransmission, neuroimmune signaling, and preclinical anxiety-model research pathways

Recent data have demonstrated that nitrated tyrosine residues, as well as acetaminophen adducts, occur in the necrotic cells following toxic doses of acetaminophen
Furthermore, glutathione itself is critical in managing oxidative stress and maintaining robust immune functionkey to healthy aging
