Aspartylphenylalanine

(3S)-3-amino-3-{[(1S)-1-carboxy-2-phenylethyl]carbamoyl}propanoic acid

C13H16N2O5 (280.1059)

Aspartylphenylalanine is a dipeptide composed of aspartate and phenylalanine, and is a metabolic byproduct of its methyl ester, aspartame (Nutrasweet). After hydrolysis of the ester bond in the intestinal lumen, the dipeptide is apparently absorbed and digested in the same manner as dipeptides derived from protein digestion. There are several Asp-Phe dipeptidases that degrade this peptide. It has been suggested that individuals with aspartame allergies may be deficient in this peptidase (PMID: 3743970). It has been observed that N-beta-aspartylphenylalanine (a breakdown product of Asp-Phe) is a naturally occurring peptide found in both blood and urine (PMID: 2723819). Degradation product of Aspartame BDS15-X.

Asparenyol is found in green vegetables. Asparenyol is a constituent of cultured cells of asparagus (Asparagus officinalis). Constituent of cultured cells of asparagus (Asparagus officinalis). Asparenyol is found in green vegetables.

Phenylalanylaspartic acid

(2S)-2-[(2S)-2-amino-3-phenylpropanamido]butanedioic acid

C13H16N2O5 (280.1059)

Phenylalanylaspartic acid is a dipeptide composed of phenylalanine and aspartic acid. 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.

L-beta-aspartyl-L-phenylalanine

2-Amino-3-[(1-carboxy-2-phenylethyl)-C-hydroxycarbonimidoyl]propanoate

C13H16N2O5 (280.1059)

L-beta-aspartyl-l-phenylalanine is a proteolytic breakdown product of larger proteins. It belongs to the family of N-acyl-alpha Amino Acids and Derivatives. These are compounds containing an alpha amino acid which bears an acyl group at his terminal nitrogen atom. It is found in urine (PMID: 3782411). A dipeptide found in urine (PMID: 3782411). This is a proteolytic breakdown product of larger proteins. [HMDB]

Levosimendan

1-cyano-N-{4-[(4R)-4-methyl-6-oxo-1,4,5,6-tetrahydropyridazin-3-yl]phenyl}methanecarbohydrazonoyl cyanide

C14H12N6O (280.1073)

Levosimendan is a calcium sensitiser used in the management of acutely decompensated congestive heart failure. It increases the sensitivity of the heart to calcium, thus increasing cardiac contractility without a rise in intracellular calcium. Levosimendan exerts its effect by increasing calcium sensitivity of myocytes by binding to cardiac troponin C in a calcium-dependent manner. It also has a vasodilatory effect, by opening adenosine triphosphate (ATP)-sensitive potassium channels in vascular smooth muscle to cause smooth muscle relaxation.

Phenprocoumon

4-Hydroxy-3-(1-phenylpropyl)-2H-1-benzopyran-2-one

C18H16O3 (280.1099)

Phenprocoumon is only found in individuals that have used or taken this drug. It is a coumarin derivative that acts as a long acting oral anticoagulant. [PubChem]Phenprocoumon inhibits vitamin K reductase, resulting in depletion of the reduced form of vitamin K (vitamin KH2). As vitamin K is a cofactor for the carboxylation of glutamate residues on the N-terminal regions of vitamin K-dependent proteins, this limits the gamma-carboxylation and subsequent activation of the vitamin K-dependent coagulant proteins. The synthesis of vitamin K-dependent coagulation factors II, VII, IX, and X and anticoagulant proteins C and S is inhibited. Depression of three of the four vitamin K-dependent coagulation factors (factors II, VII, and X) results in decreased prothrombin levels and a decrease in the amount of thrombin generated and bound to fibrin. This reduces the thrombogenicity of clots.
