Furobufen, a propionic acid derivative produced anti-inflammatory, antiarthritic, and antipyretic effects. It was shown that this compound could reduce the pain resulting from an acute inflammatory reaction and the activity profile of furobufen was similar to that of the non-steroidal anti-inflammatory drugs. Information about the current development of this compound is not available.

GSK-2636771 is a potent, orally bioavailable, PI3Kβ-selective inhibitor, sensitive to PTEN null cell lines. GSK-2636771 shows selectively inhibitory activity in PTEN null cell lines (human prostate adenocarcinoma PC-3 and breast cancer HCC70) with EC50 of 36 nM and 72 nM, respectively. GSK-2636771 significantly decreases cell viability in p110β-reliant PTEN-deficient PC3 prostate and BT549 and HCC70 breast cancer cell lines, and leads to a marked decrease of AKT phosphorylation only in the control prostate and breast cancer cell lines. On April 1 2016 GlaxoSmithKine completes a phase-I/II trial for Solid tumours (Late-stage disease) in USA, United Kingdom and South Korea (NCT01458067).

Elantrine is an anticholinergic drug. Elantrine has been investigated in the treatment of parkinsonism.

Tiformin (also known as γ-Guanidinobutyramide) is a butyramide derivate with antidiabetic activity. Tiformin was isolated for the first time from a medium containing arginine which had been transformed by washed cells of Streptomyces griseus. In preclinical models, oral administration of Tiformin depresses blood glucose in rats and rabbits. Tiformin given i.v. produced hyperglycemia and sometimes death of experimental animals. Tiformin is not significantly metabolized in the rat or dog.

Tempol is used as an industrial catalyst and chemical oxidant. However, its ability to scavenge free oxygen species has generated interest in the biochemical potential of this compound. Biologically Tempol catalyzes the disproportionation of superoxides, facilitates hydrogen peroxide metabolism, and inhibits Fenton chemistry. These properties generated investigational interest for the use of tempol to mediate radiation damage during chemotherapy. Tempol has been used in human clinical trials for mitigation of radiation damage in related to anal cancer, and brain cancer. Tempol has also been investigated in a number of animal and invitro models for conditions, such as oxidative damage, brain hemorrhage, anxiety, malaria, platelet agregation,

Quizapine is a piperazine-based nonselective serotonin (5-HT) receptor agonist with antidepressant and oxytocic activities. Quipazine targets and binds to serotonin receptors, particularly to the 5HT2A and 5HT3 receptors. Quipazine is a potential anti-parkinsonian agent. Serotonin receptor activation by quipazine may lead to smooth muscle contraction and antidepressant effects. quipazine, a central serotonergic agent, counteracted some of the drug-induced symptoms of pseudoparkinsonism in laboratory animals. Cholinergic, dopaminergic and histaminergic receptors play an important role in the manifestations of these symptoms.

Trimethamide is the antihypertensive agent.

Androsterone, a neurosteroid, acts as a positive allosteric modulator of GABA(A) receptors, that can cross into the brain and could have effects on brain function. It was discovered, that the association of beta subunits with alpha subunits GABA(A) receptor affects the sensitivity of glycine receptors to androsterone. In spite of that, androsteron is considered as an inactive metabolite of testosterone. In addition, was studied that androsterone possessed anticonvulsant properties. Although of low potency, the androsterone was present in high abundance and was able to represent endogenous modulator of seizure susceptibility.

Diaziquone is an aziridinylbenzoquinone with properties suggestive of an alkylating agent. The drug has shown broad antitumor activity against numerous transplantable murine tumors including curative activity against several intracerebrally implanted tumors. Diaziquone is rapidly and extensively metabolized by the liver. Diaziquone is a potent marrow suppressive agent inducing significant degrees of leukopenia, granulocytopenia, and thrombocytopenia in humans. Thrombocytopenia is often severe. Diaziquone alkylates and cross-links DNA during all phases of the cell cycle, resulting in disruption of DNA function, cell cycle arrest, and apoptosis. This agent can also form free radicals, thereby initiating DNA damage via DNA strand breaks. Due to its lipophilicity, diaziquone readily crosses the blood brain barrier. In phase I and preliminary phase II trials, diaziquone has demonstrated activity against primary brain tumors. Little activity has been seen in other tumor categories.

BMS 599626 is a selective and efficacious inhibitor of HER1 and HER2 with IC50 of 20 nM and 30 nM. BMS-599626 is identified as an ATP-competitive inhibitor for HER1 and as an ATP-noncompetitive inhibitor for HER2. BMS-599626 inhibits the proliferation of tumor cells expressing high levels of HER1 and/or HER2, including Sal2, BT474, N87, KPL-4, HCC202, HCC1954, HCC1419, AU565, ZR-75-30, MDA-MB-175, GEO, and PC9 cells. In a phase I trial of solid tumour patients receiving BMS 599626 no doselimiting toxicities were observed during the first cycle. Grade 1 or 2 drugrelated effects were reported and included diarrhoea, nausea, vomiting, rash, fatigue, musculoskeletal pain/cramp and cough. BristolMyers Squibb discontinued development of BMS 599626 for cancer in July 2015
