• Quinolinium small molecule5-Amino-1MQCAS 42464-96-05-Amino-1MQ is a small synthetic molecule built on the quinoline ring system: a bicyclic aromatic framework of a benzene ring fused to a pyridine ring. Quaternising the pyridine nitrogen with a methyl group gives the 1-methylquinolinium cation, and an amino substituent at the 5 position completes the structure. Because the ring nitrogen carries a permanent positive charge, the compound exists as a salt, and the iodide is the salt normally isolated.C10H11IN2·286.11 g/mol
• PeptideAdamax 984CAS On requestAdamax 984 is supplied as a lyophilised peptide. Its registry identity has not been established here, so this entry states what can be checked and nothing further.
• Synthetic hGH fragment analogueAOD-9604CAS 221231-10-3AOD-9604 is a synthetic peptide corresponding to the carboxy-terminal fragment of human growth hormone, residues 176–191, with a tyrosine added at the amino terminus. The added tyrosine shifts the conventional numbering, which is why the same molecule appears in the literature and in supplier catalogues both as Tyr-hGH(177–191) and as an hGH fragment 176–191 analogue.C78H123N23O23S2·1815.08 g/mol
• Synthetic erythropoietin-derived peptideARA-290CAS 1208243-50-8ARA-290 is a synthetic linear peptide of eleven amino-acid residues whose sequence is taken from helix B of human erythropoietin — the face of the protein that is exposed to solvent and does not participate in binding the erythropoietin receptor.
• Synthetic pentadecapeptideBPC-157CAS 137525-51-0BPC-157 is a synthetic peptide of fifteen amino-acid residues: glycine, glutamate, proline, proline, proline, glycine, lysine, proline, alanine, aspartate, aspartate, alanine, glycine, leucine, valine.

• Tripeptide thiolL-GlutathioneCAS 70-18-8L-Glutathione is a tripeptide of glutamate, cysteine and glycine, found in plant and animal cells. Its defining structural feature is the γ-glutamyl linkage at the N-terminal end: the glutamate side chain, not its α-carboxyl, forms the bond to cysteine. The cysteine thiol is free in the reduced form, and two molecules join through that thiol to form the oxidised disulfide dimer.C10H17N3O6S·307.32 g/mol
