Sulfamethazine
Sulfamethazine is only found in individuals that have used or taken this drug. It is a sulfanilamide anti-infective agent. It has a spectrum of antimicrobial action similar to other sulfonamides. [PubChem]Sulfonamides inhibit the enzymatic conversion of pteridine and p-aminobenzoic acid (PABA) to dihydropteroic acid by competing with PABA for binding to dihydrofolate synthetase, an intermediate of tetrahydrofolic acid (THF) synthesis. THF is required for the synthesis of purines and dTMP and inhibition of its synthesis inhibits bacterial growth. Pyrimethamine and trimethoprim inhibit dihydrofolate reductase, another step in THF synthesis, and therefore act synergistically with the sulfonamides.

5-hydroxyindole thiazolidine carboxylate
5-hydroxyindole thiazolidine carboxylate belongs to alpha amino acids and derivatives class of compounds. Those are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon), or a derivative thereof. 5-hydroxyindole thiazolidine carboxylate is practically insoluble (in water) and a moderately acidic compound (based on its pKa). 5-hydroxyindole thiazolidine carboxylate can be found in a number of food items such as biscuit, common pea, black salsify, and guava, which makes 5-hydroxyindole thiazolidine carboxylate a potential biomarker for the consumption of these food products.
