Thioxanthine monophosphate
Thioxanthine monophosphate is a metabolite of azathioprine. Azathioprine is a purine analogue immunosuppressive drug. It is used to prevent rejection following organ transplantation, and to treat a vast array of autoimmune diseases, including rheumatoid arthritis, pemphigus, inflammatory bowel disease, multiple sclerosis, autoimmune hepatitis, atopic dermatitis, myasthenia gravis, neuromyelitis optica or Devics disease, restrictive lung disease, and others.

2-(2-carboxy-4-methylthiazol-5-yl)ethyl phosphate
2-(2-carboxy-4-methylthiazol-5-yl)ethyl phosphate, also known as cthz-P, belongs to thiazolecarboxylic acids and derivatives class of compounds. Those are heterocyclic compounds containing a thiazole ring which bears a carboxylic acid group (or a derivative thereof). 2-(2-carboxy-4-methylthiazol-5-yl)ethyl phosphate is soluble (in water) and a moderately acidic compound (based on its pKa). 2-(2-carboxy-4-methylthiazol-5-yl)ethyl phosphate can be found in a number of food items such as rubus (blackberry, raspberry), triticale, fenugreek, and cloudberry, which makes 2-(2-carboxy-4-methylthiazol-5-yl)ethyl phosphate a potential biomarker for the consumption of these food products.
