Urea (Carbonyldiamide, Ureophil) is a highly soluble organic compound formed in the liver from ammonia produced by the deamination of amino acids. It is the principal end product of protein catabolism and constitutes about one half of the total urinary solids.

2,4-Diamino-6-hydroxypyrimidine (DAHP) is a specific inhibitor for GTP cyclohydrolase I, the rate-limiting enzyme in de novo pterin synthesis.

Cinnamic acid (Benzenepropenoic acid, Isocinnamic acid, trans-Cinnamic acid, Phenylacrylic acid), a naturally occurring aromatic fatty acid of low toxicity, induces cytostasis and a reversal of malignant properties of human tumor cells in vitro.

Umbelliferone (7-hydroxycoumarin, hydrangine, skimmetine, beta-umbelliferone) is a 7-hydroxycoumarin that is a pharmacologically active agent. It is a fluorescing compound used as a sunscreen agent and shows good inhibitions of DPPH, hydroxyl, superoxide anion and ABTS radicals with anti-inflammatory, anti-hyperglycaemic, molluscicidal and anti-tumor activities.

Levamlodipine (S-amlodipine) is a pharmacologically active enantiomer of amlodipine which belongs to the dihydropyridine group of calcium channel blocker. It acts on the L-type of calcium channels and its treatment results in vasodilation and a fall in blood pressure.

Ilaprazole (IY-81149) is a new proton pump inhibitor (PPI) used in the treatment of dyspepsia, peptic ulcer disease (PUD), gastroesophageal reflux disease (GORD/GERD) and duodenal ulcer. It inhibits H+/K+-ATPase with an IC50 of 6.0 μM.

Imipenem acts as an inhibitor of AmpC β-lactamase and is an antibiotic useful for the treatment of a number of bacterial infections.

Thymopentin (TP5) has immuno-regulatory activities. The immuno-regulatory actions of thymopentin on peripheral T cells are mediated by intracellular cyclic GMP elevations in contrast to the intracellular cyclic AMP elevations induced in precursor T cells that trigger their further differentiation to T cells.
