Clazolam (isoquinazepon) is a fuzed benzodiazepine drug developed by Sandoz in the 1960s. The drug is claimed to have anxiolytic properties, which are manifested in a reduction of cramping, antagonism of amphetamine, and by inhibition of spinal reflexes.

Diproqualone was used primarily for the treatment of inflammatory pain associated with osteoarthritis. The analgesic activity of diproqualoneis synergistic with that of noramidopyrine. It also display anti-inflammatory action in the rat, inhibiting plantar edema with dextran or serotonin, atopic edema from ovalbumin, etc. It has spasmolytic, anticholinergic and antihistaminic action in higher doses. It is not hypnotic and has no anticonvulsant effects. The therapeutic symptoms for diproqualone are all types of pain: postoperative, posttraumatic, dental, neuritis, anti-inflammatory arthritis, etc.

Anisodamine is a naturally occurring atropine derivative that has been isolated, synthesized and characterized by scientists in the People's Republic of China. Anisodamine is a non-specific cholinergic antagonist. Anisodamine has been shown to interact with and disrupt liposome structure which may reflect its effects on cellular membranes. Experimental evidence implicates anisodamine as an anti-oxidant that may protect against free radical-induced cellular damage. Its cardiovascular properties include depression of cardiac conduction and the ability to protect against arrhythmia induced by various agents. Anisodamine is a relatively weak alpha(1) adrenergic antagonist which may explain its vasodilating activity. Its anti-thrombotic activity may be a result of inhibition of thromboxane synthesis. Numerous therapeutic uses of anisodamine have been proposed including treatment of septic shock, various circulatory disorders, organophosphorus (OP) poisoning, migraine, gastric ulcers, gastrointestinal colic, acute glomerular nephritis, eclampsia, respiratory diseases, rheumatoid arthritis, obstructive jaundice, opiate addiction, snake bite and radiation damage protection. The primary therapeutic use of anisodamine has been for the treatment of septic shock. Several mechanisms have been proposed to explain its beneficial effect though most mechanisms are based upon the assumption that anisodamine ultimately acts by an improvement of blood flow in the microcirculation. Preliminary studies suggest another important therapeutic use of anisodamine is for the treatment of OP poisoning. Anisodamine has been employed therapeutically since 1965 in the People’s Republic of China primarily to improve blood flow in circulatory disorders such as septic shock, disseminated intravascular coagulation (DIC) and as an antidote to organophosphate poisoning.

Phencynonate (PHH) is a novel anticholinergic compound. It is structurally similar to scopolamine, possesses both muscarinic and nicotinic antagonistic properties as well as anti-NMDA properties. It has been developed as a safe and effective drug for the prevention of motion sickness in tablet form, it also demonstrates clear anticonvulsant effectiveness after soman poisoning in a rat model. S-isomer was more effective against motion sickness and had not anxiogenic action at therapeutic doses. S-isomer has the higher affinity and activity for mAChR in cerebral cortex and acted as a competitive mAChR antagonist. PHH was able to suppress chronic unpredictable mild stress (CUMS)-induced oxidative stress and enhance the antioxidant capacity and antioxidant proteins activity, such as superoxide dismutase 2 (SOD2) and peroxiredoxin 6 (Prdx6). PHH ameliorated CUMS-induced depressive phenotypes by up-regulating SIRT6 deacetylation activity. PHH-mediating SIRT6 pathway is required for antidepressant response and PHH can be used as a novel therapeutic to effectively treat depression. Phencynonate is in phase III clinical trials for the treatment of vertigo.

5-Methoxytryptamine (aka 5-MT, mexamine) is a tryptamine derivative closely related to the neurotransmitters serotonin and melatonin. 5-MT is produced endogenously at low levels; it is biosynthesized by deacetylation of melatonin in the pineal gland. 5-MT acts as a full agonist at the 5-HT1, 5-HT2, 5-HT4, 5-HT6, and 5-HT7 receptors. It is often used as a chemical probe in the study of serotonin receptors, but it has also been used in a clinical trial to mitigate the anemic effects of cisplatin chemotherapy.

Cenisertib (also known as R763) is water-soluble, synthetic small molecule aurora kinase inhibitor with potential antineoplastic activity. Cenisertib is a potent adenine triphosphate-competitive inhibitor of Aurora kinase isoforms A–C, disrupting mitotic spindle activity, blocking cell separation, and leading to polyploidy and cell death. At low nanomolar concentrations, Cenisertib also inhibits other kinases involved in cell survival and proliferation including FLT3, BCR-ABL1, and BCR-ABL1 with T315I mutation. It also inhibits JAK2 kinase, but at higher concentrations. Preclinically, Cenisertib has demonstrated potent antitumor activity as a single agent and in combination treatment in leukemia cell lines, freshly isolated leukemia cells, and leukemia xenograft models. Toxicities appear to be related mainly to the gastrointestinal and hematopoietic systems. In animal models, activity and toxicity depend not only on dose but also on the schedule of administration.

5-((4-(6-Chlorothieno[2,3-d]pyrimidin-4-ylamino)piperidin-1-yl)methyl)-2-fluorobenzonitrile monofumarate (PRX-08066) is a selective 5-hydroxytryptamine receptor 2B (5-HT2BR) antagonist that causes selective vasodilation of pulmonary arteries. This drug was discovered and developed by Predix (later Epix) Pharmaceuticals and is being researched for the treatment of pulmonary arterial hypertension. In animal studies, PRX-08066 has been found to reduce several key indicators of pulmonary arterial hypertension and improved cardiac output, with similar efficacy to established drugs for this condition such as bosentan, sildenafil, beraprost and iloprost.

ISPRONICLINE is a partial agonist at the a4b2 subtype of nicotinic acetylcholine receptors (nAChRs) without interaction with other nAChRs or other receptor systems. It has antidepressant, nootropic, and neuroprotective effects. It progressed to phase II clinical trials for the treatment of dementia and Alzheimer's disease but is no longer under development.

Nicocodine is an opioid related to codeine. It is also an antitussive agent. Nicocodine exhibits at least twice the potency of codeine in clinical experiments. The study of the pharmacokinetic behaviour of nicocodine by means of blood and brain level curves of rats after i .v. application showed that the penetration of the blood brain barrier seems to be favoured for nicocodine. The detected peak concentration of nicocodine in brain after i.v. application is 4.4 times higher than the blood level values at the same time - codeine the main metabolite is detected in almost equal amounts in brain and blood. A comparative assay of codeine and nicocodine after p.o. application of equimolar doses per kg body weight revealed that predominantly codeine is found in brain and its peak value after nicocodine administration is 3-fold higher than after codeine administration. Nicocodine is hydrolysable to morphine and the WHO Expert Committee on Addiction-Producing Drugs (1962) recommended its international control as a narcotic, like other convertible drugs in the morphine series.

Encaleret (JTT-305 or MK-5442) is a potent oral short-acting calcium-sensing receptor (CaSR) antagonist and transiently stimulates endogenous parathyroid hormone (PTH) secretion. CaSR antagonists stimulate endogenous PTH secretion through CaSR on the surface of parathyroid cells and thereby may be anabolic agents for osteoporosis. Japan Tobacco and Merck were developing encaleret for the treatment of osteoporosis however development has been discontinued.
