Tramiprosate
3-aminopropanesulfonic acid is an amino sulfonic acid that is the 3-amino derivative of propanesulfonic acid. It has a role as an algal metabolite, a nootropic agent, an anticonvulsant, a GABA agonist and an anti-inflammatory agent. It is a tautomer of a 3-aminopropanesulfonic acid zwitterion.

Tramiprosate binds to soluble Aβ and maintains Aβ in a non-fibrillar form. Tramiprosate is also a GABA analog and possess neuroprotection, anticonvulsion and antihypertension effects[1][2][3].
5-Hydroxypyrazinamide
Pyrazinamide. Pyrazinamide is a drug used to treat tuberculosis in afflicted patients. The drug is largely bacteriostatic, but can be bacteriocidal on actively replicating tuberculosis bacteria. -- Wikipedia; Pyrazinamide is a generic drug and is available in a wide variety of presentations. Pyrazinamide tablets are usually 500mg and form the bulkiest part of the standard tuberculosis treatment regimen. Pyrazinamide tablets are so large that some patients find them impossible to swallow: pyrazinamide syrup is an option for these patients. -- Wikipedia; Pyrazinamide is also available as part of fixed dose combinations with other TB drugs such as isoniazid and rifampicin (Rifater is an example). -- Wikipedia; Pyrazinamide is well absorbed orally. It crosses inflamed meninges and is an essential part of the treatment of tuberculous meningitis. It is metabolised by the liver and the metabolic products are excreted by the kidneys. -- Wikipedia; Pyrazinamide is a pro-drug that stops the growth of Mycobacterium tuberculosis. M. tuberculosis has the enzyme pyrazinamidase which is only active at acidic pH. Pyrazinamidase converts pyrazinamide to the active form, pyrazinoic acid. Pyrazinoic acid inhibits the enzyme fatty acid synthetase I, which is required by the bacterium to synthesise fatty acids. Mutations of the pyrazinamidase gene (pncA) are responsible for pyrazinamide resistance in M. tuberculosis. -- Wikipedia. Pyrazinamide

(2E)-2-ethylidene-4-hydroxy-5-methyl-3(2H)-furanone
(2e)-2-ethylidene-4-hydroxy-5-methyl-3(2h)-furanone is soluble (in water) and a very weakly acidic compound (based on its pKa). (2e)-2-ethylidene-4-hydroxy-5-methyl-3(2h)-furanone can be found in a number of food items such as green vegetables, black cabbage, mammee apple, and mamey sapote, which makes (2e)-2-ethylidene-4-hydroxy-5-methyl-3(2h)-furanone a potential biomarker for the consumption of these food products.
