Sulfamerazine

4-amino-N-(4-methylpyrimidin-2-yl)benzene-1-sulfonamide

C11H12N4O2S (264.0681)

Sulfamerazine is only found in individuals that have used or taken this drug.It is a sulfanilamide that is used as an antibacterial agent. [PubChem]Sulfamerazine is a sulfonamide drug that inhibits bacterial synthesis of dihydrofolic acid by competing with para-aminobenzoic acid (PABA) for binding to dihydropteroate synthetase (dihydrofolate synthetase). Sulfamerazine is bacteriostatic in nature. Inhibition of dihydrofolic acid synthesis decreases the synthesis of bacterial nucleotides and DNA.

Methionyl-Aspartate

2-{[2-amino-1-hydroxy-4-(methylsulphanyl)butylidene]amino}butanedioic acid

C9H16N2O5S (264.078)

Methionyl-Aspartate is a dipeptide composed of methionine and aspartate. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.
