5-Chloro-4-(2-imidazolin-4-on-2-ylamino)-2,1,3-benzothiazdiazole
5-Chloro-4-(2-imidazolin-4-on-2-ylamino)-2,1,3-benzothiadiazole is one of the two major metabolites of tizanidine (PMID: 9929503, 19961320). Tizanidine (trade names Zanaflex, Sirdalud) is a drug that is used as a muscle relaxant. It is a centrally acting α2 adrenergic agonist. It is used to treat the spasms, cramping, and tightness of muscles caused by medical problems such as multiple sclerosis, spastic diplegia, back pain, or certain other injuries to the spine or central nervous system. It is also prescribed off-label for migraine headaches, as a sleep aid, and as an anticonvulsant (Wikipedia).

N-acetylglutamyl-phosphate
N-acetylglutamyl-phosphate is soluble (in water) and a moderately acidic compound (based on its pKa). N-acetylglutamyl-phosphate can be found in a number of food items such as tronchuda cabbage, guava, sweet rowanberry, and acorn, which makes N-acetylglutamyl-phosphate a potential biomarker for the consumption of these food products.
