Reglitazar is a dual agonist of PPAR alpha/PPAR gamma receptors. The drug was tested in phase II clinical trial, however, its development was terminated.

Nomegestrol acetate (NOMAC) is a 19-norprogesterone derivative with high biological activity at the progesterone receptor, a weak anti-androgenic effect, but with no binding to estrogen, glucocorticoid or mineralocorticoid receptors. Nomegestrol has been developed by the Monaco-based company Théramex SAM (a Teva subsidiary). Nomegestrol acetate has been used successfully for the treatment of some gynaecological disorders (menstrual disturbances, dysmenorrhoea, premenstrual syndrome) and as a component of hormone replacement therapy in combination with estradiol for the relief of menopausal symptoms; it has been approved in Europe as monotherapy for the treatment of the menopausal syndrome, uterine diseases and menorrhagia, and in combination with an estrogen for the treatment of menopausal symptoms. Nomegestrol acetate in combination with estradiol is used as an oral contraceptive.

Cotinine is a product formed after the chemical nicotine enters the body. Measuring cotinine in people’s blood is the most reliable way to determine exposure to nicotine for both smokers and nonsmokers exposed to environmental tobacco smoke. Cotinine is safe, non-addictive and has pharmacokinetic properties adequate for therapeutic use. Research has shown that cotinine has antipsychotic, anxiolytic, and antidepressant properties and modulates the serotonergic, cholinergic and dopaminergic systems. Cotinine behaves as a positive allosteric modulator of the nicotinic acetylcholine receptors and has anti-inflammatory effects. Cotinine is under investigation as an agent for the treatment of depression, PTSD, schizophrenia, Alzheimer's disease and Parkinson's disease.

Eptazocine is an opioid analgesic which was introduced in 1987 by Morishita in Japan . It acts as a mixed κappa opioid receptor agonist and mu-opioid receptor antagonist.

GW-501516 is a peroxisome proliferator-activator receptor-delta agonist for the potential treatment of dyslipidemia, hyperlipidemia, metabolic diseases and cardiovascular diseases. GW501516 treatment is associated with significant improvements in multiple lipid profile components (TG, LDL-C, HDL-C, free fatty acids and apoB, apoA-I and apoA-II) and a shift in LDL particle size from small dense to larger, less dense particles. Despite these promising early results, the further investigation and development of GW501516 was discontinued after observations in animal studies of its association with the rapid induction of cancers in several organs (liver, stomach, tongue, skin, bladder, ovaries, womb and testes).

Alfaprostol is a synthetic analogue of prostaglandin F2α. Its activity is similar to that of the endogenous PFG2α, causing luteolysis. Alfaprostol is recommended for use in the cow, sow and mare.

Oxantel is a narrow-spectrum anthelmintic effective against whipworms in dogs and cats. It is ineffective against other roundworms, flukes, tapeworms or external parasites. Oxantel acts on the nervous system of the worms as inhibitors of acetylcholinesterase. Oxantel, a cholinergic anthelmintic and fumarate reductase inhibitor, significantly inhibited biofilm formation by P. gingivalis and disrupted established biofilms at concentrations below its MIC against planktonic cells. Oxantel was more effective against P. gingivalis in biofilm than metronidazole, a commonly used antibiotic for periodontitis. When oxantel was administrated to human beings for the treatment of trichuriasis, no drug reaction or side effects were reported, and the results of hematologic, biochemical and urinary examinations didn’t reveal any significant drug-related changes.

Clorprenaline is a β2-adrenergic receptor agonist. As a bronchodilator it has been used for the treatment of bronchial asthma, bronchitis and other respiratory diseases. It is a potential new lean meat-boosting feed additive because it can promote animal muscular mass growth and decrease fat accumulation.

Ronifibrate, a hypolipidemic agent, is an agonist of peroxisome proliferator-activated receptor.

Beraprost is a stable, orally active prostacyclin analogue. Beraprost acts by binding to prostacyclin membrane receptors ultimately inhibiting the release of Ca2+ from intracellular storage sites. This reduction in the influx of Ca2+ has been postulated to cause relaxation of the smooth muscle cells and vasodilation. Beraprost is indicated for the treatment of pulmonary hypertension and improvement of ulcers, pain & feeling of coldness associated with chronic arterial occlusion. In addition beraprost displays thyroid hormone receptor antagonistic properties.
