Pyrimethamine
Pyrimethamine is only found in individuals that have used or taken this drug. It is one of the folic acid antagonists that is used as an antimalarial or with a sulfonamide to treat toxoplasmosis. [PubChem]Pyrimethamine inhibits the dihydrofolate reductase of plasmodia and thereby blocks the biosynthesis of purines and pyrimidines, which are essential for DNA synthesis and cell multiplication. This leads to failure of nuclear division at the time of schizont formation in erythrocytes and liver.

1-Hydroxy-6-methoxypyrene
This compound belongs to the family of Pyrenes. These are compounds containing a pyrene moiety, which consists four fused benzene rings, resulting in a flat aromatic system.
p-Hydroxyphenobarbital
p-Hydroxyphenobarbital is a metabolite of Phenobarbital. Phenobarbital (INN) is a barbiturate and the most widely used anticonvulsant worldwide, and the oldest still commonly used. It also has sedative and hypnotic properties. (Wikipedia)
Hydroxynalidixic acid
Hydroxynalidixic acid is a metabolite of nalidixic acid. Nalidixic acid (tradenames Nevigramon, Neggram, Wintomylon and WIN 18,320) is the first of the synthetic quinolone antibiotics. In the technical sense, it is a naphthyridone, not a quinolone: its ring structure is a 1,8-naphthyridine nucleus that contains two nitrogen atoms, unlike quinoline, which has a single nitrogen atom.
