Vildagliptin, previously identified as LAF237, is a new oral anti-hyperglycemic agent (anti-diabetic drug) of the new dipeptidyl peptidase-4 (DPP-4) inhibitor class of drugs. Vildagliptin inhibits the inactivation of GLP-1 and GIP by DPP-4, allowing GLP-1 and GIP to potentiate the secretion of insulin in the beta cells and suppress glucaon release by the alpha cells of the islets of Langerhans in the pancreas. It is currently in clinical trials in the U.S. and has been shown to reduce hyperglycemia in type 2 diabetes mellitus. While the drug is still not approved for use in the US, it was approved in Feb 2008 by European Medicines Agency for use within the EU and is listed on the Australian PBS with certain restrictions. Vildagliptin is marketed under the trade names Galvus, Zomelis.

Piperylone is a non-narcotic analgesic and antispasmodic agent.

Fadrozole (CGS 16949A) is a tetrahydroimidazole-pyridine derivative is a non-steroidal inhibitor of aromatase. In the third phase of clinical trials it was shown, that this drug has good therapeutic effect as a second-line treatment in postmenopausal women with metastatic breast cancer.

Tropisetron (Tropisetron-AFT) is a potent and selective serotonin 3 (5-hydroxytryptamine3; 5-HT3) receptor antagonist with antiemetic properties, probably mediated via antagonism of receptors both at peripheral sites and in the central nervous system. Surgery and treatment with certain substances, including some chemotherapeutic agents, may trigger the release of serotonin from enterochromaffin-like cells in the visceral mucosa and initiate the emesis reflex and its accompanying feeling of nausea. Tropisetron (Tropisetron-AFT) selectively blocks the excitation of the presynaptic 5-HT3 receptors of the peripheral neurons in this reflex, and may exert additional direct actions within the CNS on 5-HT3 receptors mediating the actions of vagal input to the area postrema.

Zaldaride is a calmodulin antagonist known to produce inhibition of calmodulin-dependent voltage-gated ion channels including those of Ca2 , Na , and K . Zaldaride was also observed to inhibit nicotinic acetylcholine receptor (nAChR) channel currents. Zaldaride has been studied in clinical trials as a potential treatment for travelers diarrhea.

CV-205502 (Quinagolide, Norprolac), a small molecule, dopamine 2-receptor agonist was developed by Novartis for the treatment of prolactinoma and hyperprolactinaemia. It is is a long-acting dopamine agonist with potent D2 and weak D1 activity. Quinagolide exists as a racemate and its relevant clinical activity is mediated predominantly by the (-) enantiomer. It is typically present in the hydrochloride salt form and is marketed as oral tablets under the brand name Norprolac contained as a racemate. Quinagolide is currently available in several countries including Canada, but not approved for treatment in the United States. Owing to its dopaminergic action, the drug exerts a strong inhibitory effect on the secretion of the anterior pituitary hormone prolactin, but does not reduce normal levels of other pituitary hormones. Long-term treatment with Norprolac was found to reduce the size or limit the growth of prolactin-secreting pituitary macroadenomas. In some patients the reduction of prolactin secretion may be accompanied by short- lasting, small increases in plasma growth hormone levels, the clinical significance of which is unknown. As a specific inhibitor of prolactin secretion with a prolonged duration of action, Norprolac has been shown to be effective and suitable for once-a- day oral treatment of patients presenting with hyperprolactinaemia and its clinical manifestations such as galactorrhoea, oligomenorrhoea, amenorrhoea, infertility and reduced libido.
