Mezilamine is a dopamine antagonist, it blocks presynaptic but stimulates postsynaptic alpha-adrenoceptors. Potential antipsychotic drug.

Tiamenidine (also known as HOE 440) is a diazacycloalkene derivative patented by Farbwerke Hoechst A.-G. as 2 alpha-sympathomimetic antihypertensive agents. In preclinical models, tiamenidine induces hypotension and bradycardia in renal hypertensive cats and rats and in normal rats and dogs. Furthermore, Tiamenidine inhibits the liberation of norepinephrine from nerves leading to the heart and suppress sympathetic circulatory reflexes in dogs. In clinical trials, Tiamenidine exerts favor influences on systolic and diastolic blood pressure, and reduces plasma noradrenaline and adrenaline levels and suppresses plasma renin activity. Unfortunately, during the withdrawal of Tiamenidine, there is a rebound of blood pressure and plasma noradrenaline and adrenaline, overshooting baseline levels.

Methyldesorphine is a synthetic narcotic analgesic derived from morphine. It has no medicinal value in the US. This compound is listed as a Schedule I Narcotic controlled substance under the Controlled Substances Act 1970.

RGH-896 (radiprodi) is orally active and selective NMDA NR2B antagonist, a potential therapeutic agent in treatment of neuropathic pain and possibly other chronic pain conditions. It blocks pain signaling without interacting with other NMDA receptor subtypes thus potentially improving therapeutic index and side effect profile. RGH-896 is the first of this group and is currently in early clinical development. Forest and Richter initiated a Phase IIb study in neuropathic pain in the United Stated in the second half of 2006. The drug did not produce significant reductions in patient-reported pain scores for all the dosages tested. Forest says that it and Gedeon Richter will review the findings before making a decision about the further development of radiprodil. In addition to neuropathic pain, the companies intend to investigate various other pain conditions and possibly CNS indications not related to pain. Forest will pay Richter undisclosed upfront and milestone payments in addition to royalties and will have exclusive rights in the U.S. and Canada. The two companies will jointly fund the development program. RGH-896 has patent applications that provide patent protection until at least 2022.

Tixadil is a coronary vasodilator and sedative agent.

Adamantyl is adamantly derivative patented by pharmaceutical company Scherico Ltd. as spasmolytic for treatment spasms associated with Parkinson's disease.

Carburazepam (also known as Uxepam) is benzodiazepine derivative with potent anxiolytic activity and slight muscle relaxant effect. Carburazepam suppresses the avoidance reflex, orienting-research behavior and motor activity, disturbs movement coordination in rats.

Camobucol is a novel, orally active, phenolic antioxidant and anti-inflammatory compound with antirheumatic properties. Camobucol exhibited potent antioxidant activity toward lipid peroxides in vitro and displayed enhanced cellular uptake relative to a structurally related drug, probucol. This resulted in potent inhibition of cellular levels of reactive oxygen species in multiple cell types. Camobucol selectively inhibited tumor necrosis factor (TNF)-alpha-inducible levels of the redox-sensitive genes, vascular cell adhesion molecule-1 and monocyte chemoattractant protein-1, with less inhibition of E-selectin, and no effect on intracellular adhesion molecule-1 expression in endothelial cells. In addition, Camobucol inhibited cytokine-induced levels of monocyte chemoattractant protein-1, interleukin (IL)-6, and IL-8 from endothelial cells and human fibroblast-like synoviocytes as well as lipopolysaccharide-induced release of TNF-alpha, IL-1beta, and IL-6 from human peripheral blood mononuclear cells. Camobucol did not inhibit TNF-alpha-induced nuclear translocation of nuclear factor of the kappa-enhancer in B cells (NF-kappaB), suggesting that the mechanism of action is independent of this redox-sensitive transcription factor.

Methylenedioxymethamphetamine (or 3,4-methylenedioxymethamphetamine (MDMA)), a synthetic, psychoactive drug also known as ecstasy that was used as a recreational drug. This drug acts as both a stimulant and psychedelic and exerts its effects in the brain on neurons that use the chemicals serotonin, dopamine and norepinephrine to communicate with other neurons. In spite of the presence of this compound in the List of control and forbidden compounds, it was studied in psychotherapy for patients with chronic, treatment-resistant posttraumatic stress disorder. Initial results showed efficacy for the treatment approach, although further studies are needed.

Iclazepam (also known as Clazepam) was used as a tranquilliser.
