Phenethyl isothiocyanate (PEITC) presents in cruciferous vegetables which have been shown to decrease the risk of various types of malignancies. PEITC targets multiple proteins to suppress various cancer-promoting mechanisms such as cell proliferation, progression and metastasis. PEITC induces apoptosis in human colon cancer HT-29 cells, prostate cancer cells, and osteogenic sarcoma U-2 OS cells. Unique to prostate cancer is that PEITC downregulates the transcriptional factor Sp1, a regulator of AR expression. PEITC suppresses 4-(methylnitrosamino)-1-(3-pyridyl)-1-butoneinduced pulmonary neoplasia in A/J mouse lung, exhibits cancer chemopreventive activity in rat and reduces azoxymethane-induced colonic aberrant crypt foci formation. PEITC appears to be a promising agent for cancer therapy and is already under clinical trials for leukemia and lung cancer.

Diflomotecan is an E-ring modified camptothecin analogue, which possesses greater lactone stability in plasma compared with other topoisomerase I inhibitors. Diflomotecan was the first homocamptothecin to enter clinical studies. Phase I data are summarized for both the intravenous and oral schedules. The toxicity is primarily haematological while no severe gastrointestinal toxicity has been observed in contrast to other topoisomerase I inhibitors. Diflomotecan has a high oral bioavailability (72 - 95%) and the oral day 1 - 5 every 3 weeks regimen is recommended for Phase II testing because it is relatively well tolerated. Diflomotecan had been in Phase II clinical trials for the treatment of small cell lung cancer. However, this research has been discontinued.

Epothilone D (KOS-862 or BMS-241027) is an intermediary obtained in the synthesis of members of the epothilone family and is a small-molecule microtubule stabilizer. It was investigated in Phase II trials in colorectal, metastatic breast and non-small-cell lung cancers. However, development was discontinued in 2007 in favor of a second-generation analog with a better safety profile. This drug also was studied for the treatment of Alzheimer's disease. The study ended in October 2013, and evaluation of epothilone D for Alzheimer's disease was subsequently discontinued. The mechanism by which epothilones induce microtubule polymerization appears to be similar to that of paclitaxel, in that epothilones compete with paclitaxel for binding to microtubules and suppress microtubule dynamics in a manner similar to that of paclitaxel.

Eltanolone (pregnanolone) is an endogenous neuro active steroid that is biosynthesized from progesterone. It is a positive allosteric modulator of the GABAA receptor, as well as a negative allosteric modulator of the glycine receptor. There is strong evidence that it is involved in the pathophysiology of premenstrual syndrome, catamenial epilepsy, major depression, and stress-sensitive brain disorders and is known to have sedative, anxiolytic, anesthetic, and anticonvulsant effects. It was investigated for clinical use as a general (intravenous) anesthetic. It produced unwanted side effects such as convulsions on occasion, and for that reason was not marketed. Pregnanolone possesses neuroprotective and neurotrophic properties thus has been through a number of clinical trials including for treatment of traumatic brain injury (TBI), Alzheimer disease, cognitive impairment and fragile X-associated tremor/ataxia syndrome.

IPSAPIRONE, an azapirone derivative structurally unrelated to the benzodiazepines, is a selective 5-HT1A serotonin receptor agonist. It has antidepressant and anxiolytic effects. IPSAPIRONE was studied in several clinical trials for depression and generalized anxiety disorder.

Idronoxil (Phenoxodiol) is a synthetic flavonoid derivative developed by MEI Pharma for cancer treatment. Idronoxil inhibits proliferation of many cancer cell lines and induces apoptosis by disrupting FLICE-inhibitory protein, FLIP, expression and by caspase-dependent and -independent degradation of the X-linked inhibitor of apoptosis, XIAP. In addition, Idronoxil sensitizes drug-resistant tumour cells to anticancer drugs including paclitaxel, carboplatin, and gemcitabine. The antiproliferative effects of Idronoxil are associated with inhibition of plasma membrane electron transport in tumour cell lines and primary immune cells. Idronoxil displays anti-cancer activity against all forms of cancer tested in vitro and in vivo to date, using cells representative of all major forms of cancer. While having a modest ability to kill cancer cells(IC50 range between about 1-5 uM), preclinical studies point to its optimal use being to sensitize cancer cells to the toxic effects of standard therapies (chemotherapy and radiotherapy). The rationale is that a sub-lethal inhibitory effect on sphingosine kinase activity reduces the ability of the cancer cell to operate drug-resistance mechanisms and to effect repair of drug- or radiation-induced damage to DNA. In the case of cytotoxic drugs such as cisplatin, carboplatin, paclitaxel, Doxorubicin, and gemcitabine, Idronoxil is an exquisite sensitizer, increasing the cytotoxic potential of those agents by between 103 -105 times, in the process restoring sensitivity to cancer cells highly refractory to those agents.

Pelitinib (EKB-569) is a 3-cyanoquinoline pan-ErbB tyrosine kinase inhibitor with potential antineoplastic activity. Pelitinib irreversibly binds covalently to epidermal growth factor receptors, thereby inhibiting receptor phosphorylation and signal transduction and resulting in apoptosis and suppression of proliferation in tumor cells that overexpress these receptors. Pelitinib had been in phase II clinical trials for the treatment of non-small cell lung cancer and colorectal cancer. Treatment-emergent adverse events were diarrhea, abdominal pain, gastrointestinal carcinoma, intestinal obstruction and vomiting.

Etiprednol dicloacetate (BNP-166; ethyl-17alpha-dichloroacetoxy-11beta-hydroxyandrosta-1,4-diene-3-one-17beta-carboxylate) is a new soft steroid. The compound proved to be a dissociated glucocorticoid, showing a reduction in transactivating activity while preserving transrepressive abilities. The compound effectively decreased cytokine production in lipopolysaccharide-stimulated lymphocytes and attenuated lectin-induced proliferation of blood mononuclear cells in tissue culture. The significant local effect of the compound will very likely be accompanied by a drastically reduced systemic activity indicating an encouraging selectivity of the pharmacological action of etiprednol dicloacetate. Etiprednol dicloacetate had been in a clinical trial for the treatment of allergic rhinitis, asthma and Crohn's disease. However, development has been discontinued.

PF-2545920 is an orally-active phosphodiesterase 10A (PDE10A) inhibitor originated by Pfizer, for the treatment of Huntington's disease. PF-2545920 was originally developed by Pfizer for the treatment of schizophrenia. But later clinical studies for Schizophrenia were discontinued. PF-2545920 is a potent and selective PDE10A inhibitor with IC50 of 0.37 nM, with >1000-fold selectivity over the PDE. PF-2545920 is active in a range of antipsychotic models, antagonizing apomorphine-induced climbing in mice, inhibiting conditioned avoidance responding in both rats and mice, and blocking N-methyl-D-aspartate antagonist-induced deficits in prepulse inhibition of acoustic startle response in rats, while improving baseline sensory gating in mice.
