Nelotanserin is a potent, selective 5-HT(2A) inverse agonist. Originally called ADP-125, the compound was developed by Arena Pharmaceuticals as a treatment for insomnia, but failed efficacy measures for this indication in Phase 2. In 2015, Axovant Sciences licensed this compound for development, renamed it nelotanserin, and began evaluating it in dementia with Lewy bodies (DLB). Both radioligand binding and functional inositol phosphate accumulation assays suggest that nelotanserin has low nanomolar potency on the 5-HT(2A) receptor with at least 30- and 5000-fold selectivity compared with 5-HT(2C) and 5-HT(2B) receptors, respectively. Nelotanserin dosed orally prevented (+/-)-1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI; 5-HT(2A) agonist)-induced hypolocomotion, increased sleep consolidation, and increased total nonrapid eye movement sleep time and deep sleep, the latter marked by increases in electroencephalogram (EEG) delta power. Nelotanserin has been used in trials studying the treatment of Lewy body dementia, visual hallucinations, dementia with Lewy bodies, and REM sleep behavior disorder.

Evenamide (NW-3509) is a blocker of voltage-gated sodium channels. Evenamide modulates sustained repetitive firing, without inducing impairment of normal neuronal excitability. It normalizes glutamate release induced by aberrant sodium channel activity. The potential benefits of the compound have been demonstrated in numerous preclinical models predictive of efficacy in psychiatric diseases, including models of psychosis such as amphetamine-induced hyperactivity, sensorimotor gating and information processing deficits (pre-pulse inhibition impairment induced by different stimuli), mania and depression. Evenamide is being evaluated in a Phase II trial as add-on treatment to 5HT2/D2 blocking antipsychotics in schizophrenic patients.

Embramine or mebrophenhydramine is an antiallergic agent. Embramine is a histamine H₁-receptor antagonist exerting anticholinergic activity. It may inhibit stimulated platelet functions by inhibiting phospholipase A2. It is prescribed for severe allergic conditions.

Alisporivir (DEBIO-025) is a first-in-class synthetic cyclophilin inhibitor, in development with Debiopharm as an oral treatment for hepatitis C virus (HCV) infections. Alisporivir has the potential to be used for the treatment of additional diseases such as other viral infections, certain muscular dystrophies, and myocardial infarction. Alisporivir has potent anti-hepatitis C virus (HCV) activity both in vitro and in vivo. It is currently being evaluated in phase II clinical trials.

Rilozarone has been evaluated as a coronary vasodilator and an antiarrhythmic agent. Rilozarone potentially possesses a variety of cardiovascular effects, which may include Class III effects.

Betoxycaine was used as a local anesthetic.

PYM50018 (also known as Myogane or SARSAGENIN) has demonstrated neuroprotective effects in several preclinical models. It was observed that PYM50018 protects against neuronal damage, increases neurite outgrowth, reverses oxidative damage and reversed neuronal apoptosis. PYM50018 is in phase I clinical study for the treatment of amyotrophic lateral sclerosis (ALS).

ISOMETHADONE HYDROBROMIDE, DL- is a hydrobromide salt of isomethadone, a synthetic opioid analgesic. This is a controlled substance in the US.
