Bupranolol is a non-selective beta blocker without intrinsic sympathomimetic activity (ISA), but with strong membrane stabilizing activity. Bupranolol competes with sympathomimetic neurotransmitters such as catecholamines for binding at beta(1)-adrenergic receptors in the heart, inhibiting sympathetic stimulation. This results in a reduction in resting heart rate, cardiac output, systolic and diastolic blood pressure, and reflex orthostatic hypotension. Ophthalmic Bupranolol is used for the management of glaucoma and oral Bupranolol is used for the management of cardiovascular disorders. S-Bupranolol has also being shown to have superior preclinical safety profile and great antinociceptive efficacy and should be considered as a unique b-AR compound to advance future clinical pain studies.

Etafenone is an antiarrhythmic and coronary vasodilator drug. Etafenone exerts negative inotropic action on myocardium. It is able to block calcium channels. As a coronary vasodilator which produces a decrease in the heart rate and myocardial oxygen consumption, etafenone has been used in the therapy of ischemic heart disease.

Dapivirine, an anti-retroviral (ARV)-based microbicide, is a substituted diaminopyrimidine (DAPY) derivative and a potent non-nucleoside reverse-transcriptase inhibitor (NNRTI) with antiviral activity against HIV-1. Dapivirine showed high activity against wild-type and mutant HIV in in virto HIV models inhibiting a broad panel of HIV-1 isolates from different classes, including a wide range of NNRTI-resistant isolates. Developed by Janssen Sciences (formerly Tibotec Pharmaceuticals), dapivirine was initially tested as an oral treatment for HIV in a number of Phase I/II clinical trials. In 2014 the International Partnership for Microbicides (IPM) began its work on the monthly dapivirine ring. Phase I/II clinical trials in Africa, Europe and the United States proved that dapivirine is safe and well-tolerated. Phase III long-term safety and efficacy studies of the monthly dapivirine ring as part of IPM's Dapivirine Ring Licensure Program confirmed that the monthly dapivirine ring can safely help prevent HIV infection in women. In 2016 the ASPIRE Study reported a 27 percent reduction in HIV-1 acquisition with a trend toward greater protection in women over age 21 and no significant protection for women under age 21.

Roxindole (EMD-49,980) is a dopaminergic and serotonergic drug which was originally developed for the treatment of schizophrenia. Roxindole has also been investigated as a therapy for the major depressive disorder, Parkinson's disease, and prolactinoma. Roxindole is dopamine autoreceptor-selective agonistic drug with high affinity to D2-like receptors and with much lower affinities to D1-like, % and ol2, muscarinic and 5HT 2 receptors. Additionally, Roxindole exerts 5HT uptake inhibition and 5HT1A agonistic effects. The bioavailability of Roxindole has been estimated at 5% due to a high first-pass metabolization. On the other hand, in 14C distribution studies, Roxindole has crossed the blood-brain barrier readily and the brain concentrations at all intervals have been much higher than corresponding plasma levels. In clinical trials, Roxindole ‘s antipsychotic efficacy was only modest but it was unexpectedly found to produce potent and rapid antidepressant and anxiolytic effects. However, the clinical development of Roxindole was discontinued.

Azasetron is an antiemetic drug. It acts as serotonin 3 receptor antagonist. It is currently used to prevent nausea and vomiting caused by cancer chemotherapy (including cisplatin chemotherapy). Also it was demonstrated that azasetron has potent antimitogenic and apoptotic effect on cancer cell line. It was preclinically tested to treat cocaine abuse.

Iguratimod, a methanesulfonanilide, is an anti-inflammatory drug for the treatment of rheumatoid arthritis that has been developed exclusively in Japan and China. It inhibits the production of immunoglobulins and various inflammatory cytokines (interleukin-1, -6 and -8 and TNF), and exerts anabolic effects on bone metabolism by stimulating osteoblastic differentiation and inhibiting osteoclastogenesis. On the molecular level, it inhibits the nuclear transcription factor NF-κB but not its inhibitor, IκBα. In addition to these immunomodulatory and other long-lasting effects, iguratimod inhibits cyclooxygenase-2, which provides a synergistic short-term action against pain and inflammation. Efficacy and tolerability are comparable to salazosulfapyridine, and probably also to methotrexate. Combination with methotrexate is synergistic in patients with insufficient response to methotrexate and does not significantly increase adverse events.

Chloropyramine is an antagonist of H1 histamine receptors. It is indicated for the treatment of various forms of allergic reactions. Chloropyramine is a drug capable of (1) inhibiting the biochemical function of VEGFR-3 and FAK, (2) inhibiting proliferation of a diverse set of cancer cell types in vitro, and (3) reducing tumor growth in vivo.

Clocapramine is a chlorinated derivative of carpipramine. The hydrochloride has been given orally in the treatment of schizophrenia. Clocapramine is an antagonist of the Dopamine D2 and Serotonine (5-HT2) receptors. It has been implicated in at least one strange death, including a suicide. It augments the paroxetine in the panic disorder treatment.

Cyromazine, an insect growth regulator, affects larval and pupal cuticles in dipterans and some other insects. The mode of action of this aminotriazine is not known yet, though it has been shown not to inhibit the synthesis of chitin and cuticular proteins. Cyromazine may, however, act on some step(s) of sclerotization of the cuticle. Cyromazine is not a cholinesterase inhibitor. As an insect growth regulator, cyrozine exerts its toxic action by affecting the nervous system of the immature stages (larvae) of certain insects.

Gilutensin is a drug that was developed for the treatment of hypotensive circulatory disorders. As there is no information available on the drug since 1970, its development is supposed to be terminated in early phase.
