Ciladopa, is a troponylpiperazine derivative and dopamine agonist that has been shown to influence dopaminergic mechanisms in animals. Preclinical pharmacological studies have suggested that it has antiparkinsonian activity similar to that of bromocriptine but without many of the troublesome side effects. Unfortunately in some clinical trials no significant differences was found among the treatment groups and placebo.

Cogazocine is an opioid analgesic of the benzomorphan family, invented by the Dutch company ACF Chemiedfarma N.V. The compound was active in a tail withdrawal and writhing tests in rats and possessed nalorphine-like activity in rats after an intravenous dose of 0.04 mg/kg.

Desomorphine is the common name for 4,5--epoxy-17- methylmorphinan-3-ol or dihydrodesoxymorphine-D. It is an opioid analogue and morphine derivative in which the 6-hydroxyl group and the double bond at carbons 7 and 8 of morphine are reduced. Desomorphine can cross the blood–brain barrier, binding to opioid receptors, similar to the pharmacokinetic distribution of all phenanthrene-structured alkaloids. Taking Desomorphine causes euphoria as well as sedative and analgesic relief. In addition to its faster onset than other powerful painkillers drugs such as morphine, desomorphine also initiates less sedative effects and seems to have favorable postoperative results, such as reduced need for catheterization, less dizziness, and decreased vomiting incidence. In comparison with Morphine, Desomorphine is faster reduced. It follows that it has to be taken it more frequently to get the same effects. Furthermore, it causes side effects such as respiratory and gastrointestinal problems and increased blood pressure. In addition, Desomorphine’s withdrawal symptoms are up to three times longer than Morphine’s. This leads to the conclusion that Desomorphine is more addictive. At present, desomorphine is classified as a narcotic drug (DEA code number 9055) in Schedule I of the U.S. Controlled Substances Act and is listed as a controlled substance under the international Single Convention on Narcotic Drugs of 1961.

Clinolamide (cyclohexylamine of linoleic acid) is a drug developed by a Japanese company Sumitomo Chemical Co. Ltd. Clinolamide has been found to lower serum and liver cholesterol levels and to reduce the severity of atherosclerosis in cholesterol-fed rabbits.

Rosaprostol is an antiulcer drug. This compound acts on the mucosal barrier in the stomach, preventing a drop in pH. More specifically, rosaprostol exhibits gastric antisecretory activity and cytoprotective action. Importantly, it does not have the undesired side effects (such as diarrhea and uterine stimulation) of other prostanoids. Rosaprostol was found to antagonize gastric acid output induced by NSAID administration and to prevent and treat the digestive disorders that resulted from taking NSAIDs. Furthermore, symptoms in patients with gastritis disappeared after administration of rosaprostol, and the drug was well-tolerated. Positive effects of rosaprostol were also reported in patients with duodenal ulcer. Several stereoisomers of rosaprostol have been synthesized.

Cyclomenol is a bactericide compound, discovered at Institute Francais Du Petrole.

Becanthone is an antischistosomal agent possesses the ability to inhibit tumors.

Vindeburnol, a derivative of the plant alkaloid vincamine that that bears neuroprotective properties. Animal model for Alzheimer's disease has shown that vindeburnol reduced neuroinflammation and amyloid burden. In addition, the treatment with this drug can be of benefit in multiple sclerosis patients.

Lorpiprazole (brand name Normarex) is a marketed anxiolytic drug of the phenylpiperazine group. It has been described as a serotonin antagonist and reuptake inhibitor (SARI) in the same group as trazodone, nefazodone, and etoperidone.

Rolgamidine is an antidiarrheal agent. No information on current use of this compound is available.
