Egtazic acid or EGTA is widely used for biological research as a chelating agent relatively more specific for calcium ions.

Solasulfone (sulphetrone) was used in drug therapy of leprosy. It was also used in a chemotherapy of pulmonary tuberculosis. Sulphetrone has a low toxicity and an antituberculous efficiency approaching that of its parent compound, diaminodiphenylsulphone; it is also curative in infections due to beta-haemolytic streptococci.

Lysophosphatidic acid (LPA) is a multifunctional intercellular phospholipid messenger. LPA stimulates the growth of a variety of cells including fibroblasts, vascular smooth muscle cells, endothelial cells, and keratinocytes. It is produced in relatively high levels from activated platelets and can be detected in bodily fluids including serum, saliva, follicular fluid, and malignant effusions. LPA acts as a proliferative and anti-apoptotic factor and is a ligand for LPA1 (EDG-2), LPA2 (EDG-4) and LPA3 (EDG-7) receptors. The plasma LPA level can be a useful marker for ovarian cancer, particularly in the early stages of the disease. It is known, that the therapeutic administration of LPA also blocked APAP-induced liver damage, leading to an increased survival rate by increasing the glutathione level but decreasing inflammatory cytokines in an LPA1,3,5-independent manner. Thus, LPA might be an important therapeutic agent for drug-induced liver injury. In addition, was shown, that LPA levels in plasma and ascites may be useful diagnostic biomarkers for peritoneal carcinomatosis of gastric cancer.

Uric acid, generated from the metabolism of purines, has proven and emerging roles in human disease. Humans produce large quantities of uric acid. Excess serum accumulation of uric acid can lead to a type of arthritis known as gout. Hyperuricemia may increase risk factors for cardiovascular disease. High serum uric acid was associated with higher risk of type 2 diabetes and other diseases.

Disodiurn salt of Arsonoacetic acid has been used in veterinary to treat anaplasmosis (babesiasis); as general stimulant in nervous disease; for eclampsia of bitches, and with adjuncts in chronic eczema and follicular mange. Arsonoacetic acid has not featured much in human medicine, a Chinese patent however, was filed in 2003 for arsonoacetic acid and its methyl or ethyl derivatives as chemotherapeutic drugs again liver cancer.

Lactic acid, D- is a natural optical isomer of lactic acid. It is a poorly utilized isomer – 30 to 40% of the dose ingested is excreted in the urine. Lactic acid, D- is known to be harmful to human metabolism and it can result in acidosis and decalcification. D-lactic acidosis, also referred as D-lactate encephalopathy, has been reported in patients with short bowl syndrome. Lactic acid, D- is an interesting precursor for manufacturing heat-resistant polylactic acid (PLA) bioplastics which can be widely used, for example as packaging material, coatings, for textiles or in the automotive industry.
