Lonaprofen is an analgesic, antipyretic and anti-inflammatory agent.

Pirlindole is a selective and reversible inhibitor of monoamine oxidase (MAO) subtype A (MAO-A). It exerts an inhibitory effect on noradrenaline and 5-hydroxytryptamine reuptakes. It has no effect on the dopaminergic and cholinergic systems. It has only a low potential for amplifying tyramine and noradrenaline pressor effect, which makes one expect that it will not be at the basis of a ‘cheese effect’. Pirlindole was approved in some European and non-European countries for the treatment of depression. The antidepressant efficacy and safety of pirlindole have been demonstrated in a number of placebo- and active comparator-controlled studies and are supported by many years of clinical experience in the treatment of depression. The drug's efficacy and safety have also been demonstrated in the treatment of fibromyalgia syndrome. Pirlindole has a favorable tolerability profile, with no deleterious effect on cardiovascular dynamics. The effect of pirlindole on sensorimotor performance relevant to driving a motor vehicle is similar to that of placebo, as pirlindole appears to have an activating rather than a sedating antidepressant profile. Pirlindole prevented qualitative alteration (transformation) in the catalytic activity of membrane-bound type A monoamine oxidases (MAO-A), pathogenetically important for the development of the audiogenic seizures.

Dichlormezanone is the skeletal muscle relaxant. This metathiazanone was found to have a mephenesin-like type of action characterized by paralyzing, anticonvulsant, and hypothermic activities. Dichlormezanone produced an ascending type of paralysis, associated with a marked ataxia. It has anti-electroshock and anti-chemoshock activities. It was found to be active after oral administration and to have a prolonged duration of action. The daily administration of sublethal doses of dichlormezanone to albino rats for 5 consecutive days produced only an initial loss of weight. No significant hematologic alteration or macroscopic lesion of any of the viscera, attributable to medication with either drug, was observed.

Dabelotine is a cognitive-enhancing drug, developed by Servier. The drug has been shown to improve some aspects of cognitive processes, such as attention, curiosity, motivation, acquisition, and recall of memory. Dabelotine has also been shown to reduce the effect of an anticholinergic drug such as scopolamine. The drug increases the in vitro K+-induced norepinephrine release in rodent cerebral slices, and have no effect on noradrenergic and cholinergic receptor binding sites. Dabelotine was investigated in phase 2 clinical trials for the treatment of dementia, where it was demonstrated that 50-mg and 100-mg doses produced an improvement in reaction time and performance in memory tasks.

Levophencynonate is the active enantiomer of phencynonate. Levophencynonate is an anticholinergic agent which can prevent acute motion sickness with an efficacy similar to scopolamine. It will take effect by competitive binding to central muscarinic acetylcholine receptors. In April 2017 levophencynonate was in preregistration phase for the vertigo treatment in China.

OTS-167 is a maternal embryonic leucine zipper kinase (MELK) inhibitor which demonstrated antitumor properties in laboratory tests. It is being developed as an anti-cancer drug. The compound has been shown to suppress the growth of breast, lung, pancreatic and prostate cancer cells that express high levels of the MELK protein. OTS167 reached phase II clinical trials in patients with AML, ALL, advanced MDSs, advanced MPNs, or advanced CML and phase I in patients with breast cancer.

FLUMECINOL, a benzhydrol derivative, is a hepatic microsomal drug-metabolizing enzyme inducer. It was in clinical development for the treatment of pruritus associated with primary biliary cirrhosis.
