Midodrine

(+-)-2-Amino-N-(beta-hydroxy-2,5-dimethoxyphenethyl)acetamide

C12H18N2O4 (254.1266508)

Midodrine is only found in individuals that have used or taken this drug. It is an ethanolamine derivative that is an adrenergic alpha agonist. It is used as a vasoconstrictor agent in the treatment of hypotension. [PubChem]Midodrine forms an active metabolite, desglymidodrine, that is an alpha₁-agonist, and exerts its actions via activation of the alpha-adrenergic receptors of the arteriolar and venous vasculature, producing an increase in vascular tone and elevation of blood pressure. Desglymidodrine does not stimulate cardiac beta-adrenergic receptors.

Homoanserine

(2S)-2-[(4-Amino-1-hydroxybutylidene)amino]-3-(1-methyl-1H-imidazol-5-yl)propanoate

C11H18N4O3 (254.1378838)

Homoanserine (N-(4-Aminobutyryl)-L-histidine) is a dipeptide identified in the brain and muscles of mammals. (PMID 3780724, 6078589) It has been found that homoanserine is not merely deposited in skeletal muscles but that is actively synthesized by muscle cells in culture.

Valylhistidine

(2S)-2-[[(2S)-2-amino-3-methylbutanoyl]amino]-3-(1H-imidazol-5-yl)propanoic acid

C11H18N4O3 (254.1378838)

Valylhistidine is a dipeptide composed of valine and histidine. It is an incomplete breakdown product of protein digestion or protein catabolism. Dipeptides are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Some dipeptides are known to have physiological or cell-signalling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis.
