Swainsonine is an indolizidine alkaloid found in Australian Swainsona canescens, North American plants of the genera Astragalus and Oxytropis and also in the fungus Rhizoctonia leguminocola. It is competitive inhibitor of Golgi alpha-mannosidase II and lysosomal alpha-mannosidases. This compound has been reported to be a potent antiproliferative and immunomodulatory agent. However, no evidence of anti-tumor activity of swainsonine was seen in phase II clinical trial, in patients with locally advanced or metastatic renal cell carcinoma. Adverse events such as fatigue, nausea and diarrhea were common but generally mild. Swainsonine is locoweed toxin. Locoweed poisoning is seen throughout the world and annually costs the livestock industry millions of dollars. Swainsonine inhibits lysosomal alpha-mannosidase and Golgi mannosidase II. Poisoned animals are lethargic, anorexic, emaciated, and have neurologic signs that range from subtle apprehension to seizures.
AT7519M or AT7519, a small molecule inhibitor of cyclin-dependent kinases 1, 2, 4, 5, and 9, participated in phase II clinical trials in patients with relapsed or refractory chronic lymphocytic leukemia (CLL) and mantle cell lymphoma (MCL). As a result, in CLL, some patients had tumor reductions, but the objective response rate (ORR) was low. In MCL, activity was noted with ORR of 27%. In addition, AT7519M was studied in patients with previously treated multiple myeloma, to understand whether the drug alone or in combination with bortezomib were effective treatments. Recent experiments also have shown that AT7519 is a promising drug for the treatment of high-risk neuroblastoma patients with MYCN amplification. It is known, that MYCN-dependent neuroblastomas have low cure rates with current multimodal treatment.

Talmapimod is a p38 MAPK kinase inhibitor that inhibits p38 alpha with IC50 value of 9 nM which is 10-times lower then IC50 for p38 beta. Talmapimod was under clinical development for the treatment of Myelodysplastic Syndromes, Multiple Myeloma and Rheumatoid Arthritis (phase II), however, it seems to be discontinued as no longer presents in Janssen's pipeline.

Elinafide (LU 79553) is a bisintercalating naphthalamide and a topoisomerase II inhibitor has demonstrated a higher binding affinity for DNA and significant antitumour efficacy against a panel of established tumour cell lines, including several multidrug resistant-positive sublines. Elinafide had been in phase II clinical trial for the treatment of ovarian cancer and phase I trials for the treatment of various solid tumours. The major haematological toxicities observed were anaemia and neutropenia. The major non-haematological toxicities observed in the 3-weekly schedule were neuro-muscular presenting clinically as a mixed syndrome of severe weakness (sometimes with pain in both legs), myalgia and arthralgia, asthenia/fatigue/malaise. One fatality was considered related to LU 79553, as the patient had fever and neutropenia. Clinical study of this drug candidate was discontinued due to its neuromuscular dose-limiting toxicity.
Valopicitabine is a nucleoside analog and the orally bioavailable prodrug of NM107 that competitively inhibits HCV NS5B polymerase, causing chain termination. Valopicitabine had been in phase II clinical trial for once-daily oral treatment of Hepatitis C virus infection. However, because of the overall risk/benefit profile of subjects undergoing clinical trials, further development of the drug has been temporarily placed on hold by the Swiss drug major Novartis and USA-based Idenix Pharmaceuticals company and the FDA.

Roxifiban (also known as DMP754), a potent antiplatelet agent in inhibiting platelet aggregation, and has a high specificity and affinity for human platelet glycoprotein IIb/IIIa complex (GPIIb/IIIa) receptors. Roxifiban participated in clinical trials phase III for the treatment of peripheral arterial disorders. This drug was also well tolerated in patients with chronic stable angina pectoris and was studied in the treatment of heparin-induced thrombocytopenia, and thrombosis. However, the development of this drug appears to have been discontinued.

Methoxyamine (TRC102) is an orally bioavailable small molecule with potential adjuvant activity, that may potentiate the antitumor activity of alkylating agents. Methoxyamine covalently binds to apurinic/apyrimidinic (AP) DNA damage sites and inhibits base excision repair (BER) that causes topoisomerase II-dependent irreversible strand breaks and apoptosis. Methoxyamine is currently being studied in multiple Phase 1 and Phase 2 clinical trials sponsored by the National Cancer Institute or Case Comprehensive Cancer Center.
Alvameline is a partial agonist of the M1 mAChR that also displays M2/M3 antagonist effects. It readily crosses the blood-brain barrier. It has an effect profile that makes it of interest to test its ability to counteract bladder overactivity in humans. Behaviorally, alvameline has been shown to significantly improve Morris water maze (MWM) performance in both young and ageimpaired rats. It failed to improve cognition in patients with mild to moderate Alzheimer's disease.
Enrasentan is an orally active mixed endothelin A/B receptor antagonist with a 100-fold greater affinity for the endothelin A receptor. In an animal model of hypertension and cardiac hypertrophy the drug has reduced blood pressure, prevented cardiac hypertrophy and preserved myocardial function. In rats with hyperinsulinemia and hypertension enrasentan normalized blood pressure and prevented cardiac and renal damage. In rats with stroke the drug reduced the ischemic area in the brain. Enrasentan had been in phase II clinical trial for the treatment of heart failure but the results suggested that enrasentan does not appear to have favorable effects on ventricular remodeling.

Gepotidacin (formerly GSK2140944) is a novel, first-in-class, triazaacenaphthylene antibacterial that selectively inhibits bacterial DNA gyrase and topoisomerase IV by a unique mechanism, one that is not utilized by any currently approved human therapeutic agent. As a consequence of its novel mode of action, gepotidacin is active in vitro against target pathogens carrying resistance determinants to established antibacterials, including fluoroquinolones. Gepotidacin has demonstrated in vitro activity against key pathogens, including drug-resistant strains, associated with a range of conventional and biothreat infections. GlaxoSmithKline is developing Gepotidacin for the treatment of gonorrhoea and skin and soft tissue infections.
