Meseclazone (W-2395) is a non-steroidal anti-inflammatory drug. It exerts anti-inflammatory, analgesic and antipyretic activity. Meseclazone inhibits in vitro and ex vivo platelet aggregation initiated by the release reaction. It inhibits bradykinin-induced bronchospasm.

Cianergoline is an ergoline derivative with marked dopaminergic agonist and a predominant cardiovascular action patented by Farmitalia Carlo Erba S.p.A for hypertension treatment. The preclinical evaluation shows dose-related hypotensive effects after single oral, intraduodenal and intravenous administration of Cianergoline in cats, dogs, and rats. Cianergoline showed a prompt onset of action and a prolonged effect on blood pressure at low doses without substantially modifying animals heart rate. One month daily oral administration of Cianergoline in rats produced an antihypertensive effect persisting through the entire experiment with no signs of tachyphylaxis. Unfortunately, in clinical trials Cianergoline caused a slight, statistically non-significant blood pressure lowering effect in patients with essential hypertension and does not modify the release of prolactin, lipid metabolism or the basal activity or postural responsiveness of the renin-angiotensin-aldosterone axis and of the sympathetic nervous system.

Damotepine is a derivative of thiepin, structurally related to doxepin. Damotepine was discovered by the Swiss pharmaceutical company Geigy A.G. and was evaluated in clinical trials for the treatment of anxiety in the early 1970s.

Cericlamine (INN) is a potent and moderately selective serotonin reuptake inhibitor (SSRI) of the amphetamine family that was investigated as an antidepressant for the treatment of depression, anxiety disorders, and anorexia nervosa by Jouveinal

Diethylthiambutene is an analgesic agent with an effect like that of morphine. Diethylthiambutene mainly used in veterinary. It is highly toxic to cats. Can cause convulsions if injected intravenously. Diethylthiambutene is a synthetic opioid drug. It is under international control according to the UN Single Convention 1961 and its amendments, schedule I.

Fasobegron is an agonist of β3-adrenoreceptor.

Vabicaserin is a 5-hydroxytryptamine 2C (5-HT2C) receptor-selective agonist with an EC50 of 8 nM. Pfizer was developing vabicaserin, an oral serotonin (5-HT)2C receptor agonist, for the treatment of schizophrenia and bipolar disorder. Vabicaserin decreases nucleus accumbens extracellular dopamine levels in rats, without affecting striatal dopamine, indicating mesolimbic selectivity. Vabicaserin had been in phase II clinical trials for the treatment of schizophrenia. However, research of Vabicaserin for the treatment schizophrenia and obesity was discontinued.

Ruzadolane (previously known as UP 26-91) is a serotonin receptor antagonist that was developed as a non-narcotic, centrally acting analgesic agent for the treatment of anxiety disorder and pain. However, these studies were discontinued.

Clodacaine is a local anesthetic drug, invented by Cilag AG in the late 1950s.

Esmirtazapine (S-(+)mirtazapine or ORG-50081) is an enantiomer of mirtazapine (REMERON®), a high-affinity antagonist at 5-HT2/5-HT3 and H1 receptors, used in the treatment of depression. Esmirtazapine has a shorter plasma half-life than the R(−) enantiomer. Esmirtazapine is preferentially metabolized into an 8-hydroxy glucuronide. Organon was developing esmirtazapine for the treatment of hot flushes (vasomotor symptoms) associated with the menopause and insomnia.
