Ramifenazone is pyrazolone derivative with analgesic, antipyretic, and anti-inflammatory activity. In preclinical studies, Ramifenazone shows potent inhibition of prostaglandin production, carrageenan edema, and yeast fever.

Manozodil is a vasodilator agent.

Nastorazepide (Z-360) is a selective, orally available, gastrin/cholecystokinin 2 (CCK-2) receptor antagonist with potential antineoplastic activity. Z-360 binds to the gastrin/CCK-2 receptor, thereby preventing receptor activation by gastrin, a peptide hormone frequently associated with the proliferation of gastrointestinal and pancreatic tumor cells. It is currently under development as a therapeutic drug for pancreatic cancer, gastroesophageal reflux disease and peptic ulcers. The most commonly reported adverse events were nausea, abdominal pain, vomiting and fatigue.

PHA-793887 is an inhibitor of multiple cyclin dependent kinases (CDK) with activity against CDK2, CDK1 and CDK4. PHA-793887 was cytotoxic for leukemic cell lines in vitro, with IC(50) ranging from 0.3 to 7 uM. In colony assays PHA-793887 showed very high activity against leukemia cell lines, with an IC(50) <0.1 uM indicating that it has efficient and prolonged antiproliferative activity. PHA-793887 induced cell-cycle arrest, inhibited Rb and nucleophosmin phosphorylation. PHA-793887 has promising therapeutic activity against acute leukemias in vitro and in vivo.

Ortetamine, also known as 2-methylamphetamine, is a monoamine releaser that was studied as a stimulant drug. Information about the current use of this drug is not available.

Fasitibant (MEN-16132) is a non-peptide sulfonamide-containing bradykinin hB2 receptor antagonist. It inhibits pro-inflammatory response in vitro and alleviates inflammatory hyperalgesia in rodent models of osteoarthritis. Menarini Group was developing fasitibant for the treatment of osteoarthritis. Fasitibant development has been discontinued.

Oxodipine is a dihydropyridine calcium channel blocker that has been developed by IQB as an antihypertensive agent. Experiments on dogs have shown that oxodipine exerted a relatively specific action on blood vessels without significant intrinsic negative chronotropic properties. in addition, in Europe, the drug was involved in phase III clinical trials in and in phase II for the treatment of Hypertension. Besides, oxodipine was studied for the treatment of ischaemic heart disorders. However, these studied were discontinued.

Pytamine is a nitrosamine derivative patented by Hercules Powder Co. as antioxidants, stabilizers, rubber additives, insecticides, fungicides, bactericides, and pharmaceutical intermediates. In preclinical trials Pytamine shows potent psychotropic effects associated modulation of GABAA receptors.
