(E)-Tetrachlorovinphos is an (E)- isomer of Tetrachlorovinphos. Tetrachlorovinphos is an organophosphate cholinesterase inhibitor that is used as an insecticide. Tetrachlorvinphos was introduced and first used commercially in 1966 in the USA. Tetrachlorvinphos was originally registered for use on various food crops, livestock, pet animals. Tetrachlorvinphos is applied dermally to livestock to control flies and mites. It is used as an oral larvicide in cattle, hog, goats and horses; in cattle ear tags to control flies; in cattle feedlots; in poultry dust boxes to control poultry mites; and in poultry houses. Tetrachlorvinphos also is used in pet sleeping areas and pet flea collars and to control flies around refuse sites, recreational areas, and for general outdoor treatment. Tetrachlorvinphos can cause cholinesterase inhibition in humans; that is, it can overstimulate the nervous system causing nausea, dizziness, confusion, and at very high exposures (e.g., accidents or major spills), respiratory paralysis and death. In 2014, the Natural Resources Defense Council (NRDC) filed a lawsuit against the United States Environmental Protection Agency (EPA) seeking EPA to respond to NRDC’s 2009 petition to ban tetrachlorvinphos in common pet flea treatment products. Tetrachlorvinphos is reportedly registered for use in Canada, South Africa, and Australia.

Aptocaine (Pirothesin, Pharmaceutical Manufacturing Company) is a new local anaesthetic agent, the first of note to be synthesized in Britain. It is related toprilocaine; like prilocaine, it has a low sub-cutaneous toxicity, but preliminary studies suggest that, unlike prilocaine, it does not induce methaemoglobinaemia. It has been found to produce satisfactory analgesia, of longer duration than lignocaine, by several routes, at a concentration of 3% in animals.

Sitravatinib (MGCD516) is a receptor tyrosine kinases (RTK) inhibitor that blocks a wide array of RTKs known to be amplified/overexpressed in sarcomas, which are key regulators of signaling pathways that lead to cell growth, survival and tumor progression. It is involved in driving sarcoma cell growth with IC50 of 3980 nM and is superior to other multi-kinase inhibitors in inhibiting cell proliferation, RTK phosphorylation, and phosphorylation of downstream effectors. The efficacy of sitravatinib was tested using a wide panel of sarcoma cell lines, including malignant peripheral nerve sheath tumor (MPNST), Ewing sarcoma (A673), osteosarcoma (Saos2), and liposarcoma (DDLS, LS141). Both in vitro and in vivo efficacy sitravatinib was significantly better that the other two multi-kinase inhibitors, imatinib and crizotinib. Sitravatinib treatment not only inhibits tumor cell proliferation at low nanomolar concentrations in vitro but also results significant tumor growth suppression in vivo in mouse xenograft models. Sitravatinib is being evaluated in a Phase 1b dose expansion cohort in selected patients with specific genetic alterations that are drivers of tumor growth, with an initial focus on Non-Small-Cell Lung carcinoma (NSCLC) and in other solid tumors where sitravatinib may confer a benefit. Its efficacy and safety is also being tested in Phase II clinical trials in patients with advanced liposarcoma as a monotherapy and NSCLC in combination with nivolumab.

18-Methoxycoronaridine (18-MC) is a derivative of ibogaine invented in 1996 by the research team around the pharmacologist Stanley D. Glick from the Albany Medical College and the chemist Martin E. Kuehne from the University of Vermont. In animal studies it has proved to be effective at reducing self-administration of morphine, cocaine, methamphetamine, nicotine and sucrose. 18-MC is a α3β4 nicotinic antagonist and, in contrast to ibogaine, has no affinity at the α4β2 subtype nor at NMDA-channels nor at the serotonin transporter, and has significantly reduced affinity for sodium channels and for the σ receptor, but retains modest affinity for μ-opioid receptors where it acts as an antagonist, and κ-opioid receptors. The sites of action in the brain include the medial habenula, interpeduncular nucleus, dorsolateral tegmentum and basolateral amygdala. Unlike ibogaine and its principal metabolite noribogaine, 18-MC does not increase expression of glial cell line-derived neurotrophic factor (GDNF) in a dopaminergic–like cell line. 18-Methoxycoronaridine is a potent leishmanicide effect against Leishmania amazonensis, a causative agent of cutaneous and diffuse cutaneous leishmaniasis in the New World.

BL-1021 was developed by BioLineRx Ltd. for the treatment of neuropathic pain or pain that results from damage to nerve fibers. The drug has completed phase I clinical trials, however further information is not available.

Bucricaine is tetrahydroaminoacridine derivative that has been studied as acetylcholinesterase and monoamine oxidase inhibitor. In animal models, Bucricaine shows a wide spectrum of pharmacological properties, which include analgesic, local anesthetic, analeptic, and respiratory stimulant activities.

Decloxizine (UCB-1402; NSC289116) is a histamine 1 receptor antagonist. Decloxizine is a broncholyticum.

Nornicotine is a natural alkaloid produced by plants in the genus Nicotiana and is structurally related to nicotine. Nornicotine is the direct precursor of tobacco-specific nitrosamine N'-nitrosonornicotine, which is a highly potent human carcinogen. Nornicotine is an active nicotine metabolite, which accumulates in brain to pharmacologically relevant concentrations following repeated nicotine administration to rats. Nornicotine stimulated DA release from nucleus accumbens in a nicotinic receptor-mediated manner, further supporting the hypothesis that nornicotine contributes to tobacco dependence. Nornicotine is present in Nicotiana tobaccum in both S(-) and R(+) enantiomeric forms. Nornicotine enantiomeric forms appear to differ in analgesic potency and side effects. Exposure to nornicotine results in additional activation of α7-type receptors, which may be important for effects on cognition and attention. Likewise, the effects of nornicotine on α6-containing receptors may contribute to the reinforcing effects of nicotine, and therefore, is relevant to dependence on tobacco. In contrast to nicotine, nornicotine had relatively low activity on receptors other than those containing α7 or α6 subunits. Yaupon Therapeutics was developing Nornicotine as a once a day oral drug for smoking cessation. However this development was discontinued.

FEPRADINOL is an analgesic, antipyretic and anti-inflammatory agent. Its anti-inflammatory activity does not seem to be related to an inhibitory effect on prostaglandin biosynthesis.
