Oxolamine under brand names Symphocal, Perebron is used in some countries as a cough suppressant for the treatment of pharyngitis, tracheitis, bronchitis, bronchiectasis, pertussis. Oxolamine possesses anti-inflammatory activity, which causes a reduction in the irritation of the nervous receptors of the respiratory tract.

Indoxacarb is a new oxadiazine insecticide discovered and developed by DuPont. The indoxacarb racemate contains two enantiomers (S : R), designated DPX-KN128 and DPX-KN127, but only the S enantiomer has insecticidal activity. It inhibits insect neuronal voltage-dependent sodium channels. Indoxacarb is an active component of Merck Activyl® used in the treatment of flea and tick in dogs and cats. DuPont™ Steward® WG is a water dispersible granule stomach and contact insecticide powered by Indoxacarb for control of various insect pests on a variety of crops.

Rimonabant (also known as SR141716; trade names Acomplia, Zimulti) was an anorectic antiobesity drug that was first approved in Europe in 2006 but was withdrawn worldwide in 2008 due to serious psychiatric side effects. Rimonabant is an inverse agonist for the cannabinoid receptor CB1 and was the first drug approved in that class. There is considerable evidence that the endocannabinoid (endogenous cannabinoid) system plays a significant role in appetitive drive and associated behaviors. It is, therefore, reasonable to hypothesize that the attenuation of the activity of this system would have therapeutic benefit in treating disorders that might have a component of excess appetitive drive or over-activity of the endocannabinoid system, such as obesity, ethanol and other drug abuse, and a variety of central nervous system and other disorders. Data from clinical trials submitted to regulatory authorities showed that rimonabant caused depressive disorders or mood alterations in up to 10% of subjects and suicidal ideation in around 1%, and in Europe, it was contraindicated for people with any psychiatric disorder, including depressed or suicidal people. Additionally, nausea and upper respiratory tract infections were very common (occurring in more than 10% of people) adverse effects; common adverse effects (occurring in between 1% and 10% of people) included gastroenteritis, anxiety, irritability, insomnia and other sleep disorders, hot flushes, diarrhea, vomiting, dry or itchy skin, tendonitis, muscle cramps and spasms, fatigue, flu-like symptoms, and increased risk of falling.

Loxoprofen (INN) is a non-steroidal anti-inflammatory drug in the propionic acid derivatives group. It is marketed in Brazil, Mexico and Japan by Sankyo as its sodium salt, loxoprofen sodium, under the trade name Loxonin, Argentina as Oxeno and in India as Loxomac. It is available in these countries for oral administration, and a transdermal preparation was approved for sale in Japan on January 2006. It is usually used to treat rheumatoid arthritis and osteoarthritis. It is also used to reduce pain and inflammation after surgery, wounds and tooth removal, as well as to bring down fever or ease pain induced by acute inflammation of upper respiratory tract Loxoprofen is a prodrug. When administered orally, loxoprofen sodium hydrate is absorbed from the gastrointestinal tract as an unchanged compound with only a modest gastric-mucosal irritation. It is then rapidly biotransformed into the active metabolite trans-OH form (SRS coordination) with a potent inhibitory effect on prostaglandin biosynthesis to exert its pharmacologic effects. Inhibition of prostaglandin biosynthesis constitutes the mechanism of action of this drug, the site of action being cyclooxygenase.

Bucindolol is a third-generation, non-selective β-adrenergic receptor blocker, that acts on both β-1 and β-2 receptors. Bucindolol’s additional α-1 antagonistic activity contributes to its mild vasodilator effect. It was rejected by the FDA for the heart failure, because of the unreviewed submissions deal with comparative effectiveness, clinical pharmacology, some aspects of pharmacogenetic data, and toxicology/metabolism. In addition, bucindolol is in the phase II of clinical trial for the treatment of atrial fibrillation.

Bopindolol (4-[benzoyloxy-3-tertbutylaminopropoxy]-2-methylindole hydrogen malonate) is an indole beta-adrenoceptor antagonist bearing a benzoyl ester residue on the beta-carbon atom of the propanolamine side chain. Bopindolol is metabolized by esterase to benzoic acid and an active metabolite, 18-502 [4-(3-t-butylamino-2-hydroxypropoxy)-2-methyl indole], which is further metabolized to 20-785 [4-(3-t-butylaminopropoxy)-2-carboxyl indole]. Bopindolol produces sustained blockade of beta 1- and beta 2-adrenoceptors, has intrinsic sympathomimetic as well as membrane stabilizing actions, inhibits renin secretion, and interacts with 5-HT receptors. Bopindolol is used in the treatment of hypertension. In limited trials bopindolol has also successfully reduced symptoms in patients with angina pectoris, anxiety and essential tremor.

Frentizole, a nontoxic antiviral and immunosuppressive agent, was used clinically in rheumatoid arthritis and systemic lupus erythematosus. Frentizole was more effective in suppressing human lymphocytes responding to Con A and PWM, than it was in cells activated by PHA, specific antigen, or alloantigen. Methylprednisolone, on the other hand, was more inhibitory for cells stimulated by PHA, specific antigen, or alloantigen. Frentizole, even at super immunosuppressive doses, does not predispose the hose (mice) to Pseudomonas aeruginosa, Candida albicans, herpes simplex virus, or Ann Arbor influenza virus. Frentizole is an inhibitor of the Aβ-ABAD interaction.

Roquinimex (Linomide, LS 2616) is a quinoline-3-carboxamide with pleiotropic immune modulating capacity and it has therapeutic effects in several experimental animal models of autoimmune diseases. Linomide has been evaluated in clinical trials for multiple sclerosis, and was indeed shown to have disease inhibitory effects. However, due to unexpected side effects recorded in patients treated with Linomide, premature termination of clinical trials was required. The basic mechanism(s) of action of Linomide in inducing beneficial effects in autoimmune diseases is still elusive. Some experimental evidence indicates that Linomide influences the regulation of the cytokine profile, resulting in the inhibition of autoimmune and inflammation pathologies. Roquinimex possesses potential antineoplastic activity. Roquinimex inhibits endothelial cell proliferation, migration, and basement membrane invasion; reduces the secretion of the angiogenic factor tumor necrosis factor alpha by tumor-associated macrophages (TAMs); and inhibits angiogenesis. Roquinimex was in phase III clinical trials with Pharmacia Corporation in Europe and the US for the treatment of multiple sclerosis.

Amithiozone, also known as thioacetazone, is an oral antibiotic, which is used in the treatment of tuberculosis. In 1991, the World Health Organization (WHO) recommended replacing thioacetazone with ethambutol in patients with known or suspected HIV infection. Thioacetazone is no longer included in WHO’s recommended first-line treatment for tuberculosis and is now reserved for uncommon situations in which treatment options have been compromised by resistance to other anti-tuberculosis medicines in HIV-negative individuals. Despite the increased recognition of this risk, thioacetazone remained in use mainly in low-income countries because of its low cost. Amithiozone has also been used in trials studying the treatment of Mycobacterium Avium-intracellular Infection. One of the possible mechanism action of the drug is interference with the metabolism of methionine of susceptible tubercle bacilli, which utilize methionine for nucleic acid synthesis.

Armin is irreversible cholinesterase inhibitor. It acts considerably longer and stronger than reversible cholinesterase inhibitors. It is used for glaucoma treatment. Armin might be used in combination with other antiglaucoma drugs. Known adverse effects are: hypersalivation, sweating, dyspepsia, frequent urination, blurred vision, headache, dizziness, twitching of the tongue and skeletal muscles, nausea, vomiting.
