Brocrinat is an ethacrynic acid derivative with diuretic activity. Chronic dosing with Brocrinat does not increase plasma uric acid suggests that therapeutically, Brocrinat as a diuretic may be useful in patients where control of plasma uric acid is desirable..

Ertiprotafib was originally developed as an inhibitor of PTP1B. Multiple targets of ertiprotafib, in addition to PTP1B inhibition, have been suggested including dual PPARalpha/PPARgamma agonism and IKK-beta inhibition. It normalized the plasma glucose and insulin levels in diabetic animal models and progressed to a phase II clinical trial for the treatment of Type 2 diabetes mellitus. Ertiprotafib development has been discontinued.

Cyclobutoic acid is a synthetic analog of mevalonic acid, developed by the Italian company Farmitalia Carlo Erba SPA. The compound inhibited the incorporation of [14C] into CO2, fatty acids and cholesterol, and was used for the treatment of hepatic deficiency.

Sulfaloxic acid is a benzamide derivative patented by Chemische Fabrik von Heyden A.-G. as an antibacterial agent.

Etoxeridine (Carbetidine or Wy2039), a piperidine derivative, is a narcotic analgetic.

Droxacin is quinolone antibiotic. It is topoisomerase inhibitor.

Octimibate is a non-prostanoid inhibitor of platelet aggregation that acts via the prostacyclin receptor.

Tiomolibdic acid salt, Bis-choline tetrathiomolybdate (ATN-224, WTX-101), is under investigation as a therapy against different cancers and Wilson’s disease (WD). ATN-224 is a second-generation analog of ammonium tetrathiomolybdate. ATN-224 is a novel copper chelator. ATN-224 inhibits CuZn superoxide dismutase 1 (SOD1) leading to antiangiogenic and antitumor effects. Strategically tailoring combination regimens that include ATN-224 and target ROS may be a viable approach to advance the treatment of melanoma. ATN-224 is in phase III clinical trial for the treatment of Hepatolenticular degeneration. WTX-101 is in phase II clinical trials for the treatment of Wilson's disease. Once daily WTX-101 treatment over 24 weeks improved neurologic disease, hepatic status and copper control in newly diagnosed WD patients. WTX-101 appears well tolerated. Drug-induced, paradoxical, neurological deterioration was not observed. This compound has received orphan drug designation in both the United States and the European Union. WTX-101 was originally discovered by University of Michigan and now is being developed by Wilson Therapeutics by acquisition.

Lifibrol is a hypocholesterolemic compound. The effect of lifibrol on serum cholesterol levels has been examined in several animal models and clinical trials. The efficacy of lifibrol in lowering total cholesterol, LDL cholesterol, and apo B is comparable to the 3-Hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, the most potent lipid-lowering drugs known so far. In addition, lifibrol reduces serum triglycerides, lipoprotein (a), and fibrinogen. lifibrol acts synergistically upon key regulatory processes of cholesterol homeostasis: it reduces cholesterol absorption from the intestine, moderately decreases hepatic cholesterol biosynthesis and stimulates the expression of low density lipoprotein receptors, presumably by a sterol-independent mechanism. Lifibrol had been in phase II clinical trials for the treatment of hypercholesterolaemia. However, this study was discontinued. It has the potential to accumulate in the liver and induce hepatic peroxisome proliferation.
