Niravoline [RU 49679, RU 51599, niravolin], a novel aqueous diuretic with κ-opioid agonistic action. The drug was originally being developed by Hoechst Marion Roussel. Niravoline is a selective agonist of kappa-opioid receptors having potent aquaretic activity. Niravoline was studied with respect to the treatment of brain oedema, heart failure and liver cirrhosis. Niravoline, administered at moderate doses, safely induced a powerful aquaretic effect in patients with cirrhosis and ascites. Moderate doses of niravoline appeared to be a
promising pharmacological tool in the treatment of water retention in patients with cirrhosis. The development of niravoline as an aquaretic for the treatment of cirrhosis with ascites and other hyponatraemic disorders has also been halted.

Cilengitide is a cyclized Arg-Gly-Glu (RGD)-containing pentapeptide that selectively blocks activation of the αvβ3 and αvβ5 integrins. Its precursor was first synthesized in 1995 as c(RGDfV), and later modified by the incorporation of N-methyl Val c(RGDfMetV), generating the current form of the drug. Cilengitide displays subnanomolar antagonistic activity for αvβ3 and αvβ5, and is the first integrin antagonist evaluated in clinical phase I and II trials for treatment of glioblastoma and several other tumor types. Cilengitide-induced glioma cell death and inhibition of blood vessel formation may use different molecular mechanisms, including regulation of tumor hypoxia and activation of apoptotic pathways. Cilengitide inhibits cell signaling through FAK-Src-Akt and Erk mediated pathways in endothelial and tumor cells and attenuates the effect of VEGF stimulation on growth factor signaling. Cilengitide has shown encouraging activity in patients with glioblastoma as single agent, and in association with standard RT and temozolomide.

Batabulin or T138067 (2-fluoro-1-methoxy-4-pentafluorophenylsulfonamidobenzene) covalently and selectively modifies the beta1, beta2, and beta4 isotypes of beta-tubulin at a conserved cysteine residue, thereby disrupting microtubule polymerization. Cells exposed to batabulin become altered in shape, indicating a collapse of the cytoskeleton, and show an increase in chromosomal ploidy. Batabulin is equally efficacious in inhibiting the growth of sensitive and multidrug-resistant human tumor xenografts in athymic nude mice. Batabulin has been in clinical trials for the treatment of cancers (breast cancer, colorectal cancer, glioma, hepatocellular carcinoma, non-small cell lung cancer). It does not have clinical activity in the treatment of colorectal cancer and glioma. Batabulin development was discontinued.

Talaglumetad (also known as LY-544344) is a bicyclohexane derivative patented by Eli Lilly and Company as modulators of metabotropic glutamate receptor. Talaglumetad acts as a prodrug of Eglumegad, a selective agonist of metabotropic glutamate receptors (mGluR2/3) and metabolized to release active compound by both human jejunal homogenates and rat liver homogenates. In experiments on mice, Talaglumetad was found to be as effective as diazepam for treating anxiety symptoms in several standard tests, but without producing any of the negative side effects of diazepam such as sedation and memory impairment.

Picenadol is a 4-phenylpiperidine derivative and a racemic mixture whose mixed agonist-antagonist properties are a consequence of the d-isomer being a potent opiate agonist, whereas the I-isomer is an opioid antagonist. In the mouse writhing and rat tail heat tests, the analgesic potency of picenadol is estimated to be 1/3 that of morphine. Picenadol itself has weak antagonist activity, whereas the antagonist potency of the l-isomer is approx. 1/10 that of nalorphine. Picenadol has high affinity for both the mu and delta receptors but a markedly lower affinity for the kappa receptor. Extensive pharmacological investigations show picenadol to have a low potential to produce opiate-like side effects, including a low liability for abuse and physical dependence. Antinociceptive properties of picenadol arise from mu agonist actions of the dextrorotatory isomer and that the levorotatory isomer acts to limit the efficacy of the racemate.

Edatrexate (10-ethyl-10-deazaaminopterin or 10-EDAM) is an analog of methotrexate with improved pre-clinical antitumor activity, more selective cellular uptake, and with the more extensive formation of intracellular polyglutamate metabolites. This drug is a new dihydrofolate reductase inhibitor, which was studied in phase II clinical trial for the patients with different cancers. The studies were discontinued, for example, in advanced renal cell carcinoma edatrexate in the investigated dose and schedule had minimal activity and was toxic. In case of non-small-cell lung cancer, the dosing schedule of edatrexate did not appear to be improved compared to other chemotherapeutic regimens. In addition, edatrexate was involved in the experiment for the treatemnt of rheumatoid arthritis, but this study was also discontinued.

Troxacitabine is a synthetic nucleoside analogue. It is a poor substrate for nucleoside transporters and gains entry into cells by passive diffusion. Intracellular conversion to its active triphosphate form is via deoxycytidine kinase. Incorporation of this metabolite into DNA results in immediate chain termination and apoptosis induction. It is the first nucleoside analog with anticancer activity that has an unnatural stereochemical configuration. The dose-limiting adverse reactions were stomatitis and hand–foot syndrome.

Nitramisole, an imidazothiazole derivative, is an anthelmintic. Nitramisole was effective against migrating Strongylus vulgaris larvae in ponies. Treatment of infected ponies with Nitramisole resulted both a clinical and radical cure.
