Lafutidine is a novel histamine H2 antagonist with gastroprotective activity. Lafutidine exhibited potent and long-lasting H2 antagonism and prolonged antisecretion. In addition, lafutidine showed a gastroprotective effect against noxious agents-induced gastric mucosal damage through capsaicin-sensitive afferent nerves. Lafutidine showed antiulcer activities against acute ulcer models, prevented gastric ulcer relapse of acetic ulcer. Adverse events observed during clinical trials included constipation, diarrhea, drug rash, nausea, vomiting and dizziness.It also activates calcitonin gene-related peptide, resulting in the stimulation of nitric oxide (NO) and regulation of gastric mucosal blood flow, increases somatostatin levels also resulting in less gastric acid secretion, causes the stomach lining to generate more mucin, inhibits neutrophil activation thus preventing injury from inflammation, and blocks the attachment of Helicobacter pylori to gastric cells

Omapatrilat is an antihypertensive agent that inhibits both neprilysin (neutral endopeptidase, NEP) and angiotensin-converting enzyme (ACE). The drug was developed for possible use in heart failure and hypertension, but was not approved by the FDA due to angioedema safety concerns.

Bergapten, known as 5-methoxypsoralen, a cumarine-derivate compound, presents in many fruits and vegetables. It has shown antitumor effects in a variety of cell types. The key target of bergapten action in breast cancer cells was identified the oncosuppressor gene PTEN (phosphatase tensin homolog deleted from chromosome 10); bergapten by inducing PTEN expression, produces autophagy in breast cancer cells. Besides, bergapten is under investigation in clinical trial phase III for patients with severe generalized atopic dermatitis.

Bucillamine [SA96:N-(2-mercapto-2-methylpropanoyl)-L-cysteine] is a synthetic SH compound and an antirheumatic agent developed from tiopronin. It is mainly used in Japan and Korea. Activity is mediated by the two thiol groups that the molecule contains. Research done in the USA showed positive transplant preservation properties. Bucillamine has the potential to attenuate or prevent damage during myocardial infarction, cardiac surgery and organ transplantation. Bucillamine is a more potent thiol donor than other cysteine derivatives: approximately 16-fold more potent than N-acetylcysteine (Mucomyst(R)) in vivo. In addition bucillamine appears to have additional anti-inflammatory effects unrelated to its antioxidant effect. Oral bucillamine is used clinically in Asia for treatment of rheumatoid arthritis. There is a strong preclinical evidence that parenteral infusion of this agent is efficacious in acute settings characterized by inflammation and oxidative stress. In Phase I human trials healthy volunteers received bucillamine at doses up to 25 mg/kg/h i.v. for 3 h and elicited no serious toxicity. On the basis of pharmacokinetic analyses of blood levels during these studies, it was concluded that bucillamine infused at i.v. doses > or =10 mg/kg/h for 3 h to humans could be expected to be therapeutically effective in myocardial infarction, organ transplantation and other acute inflammatory syndromes. Bucillamine exhibits potent antioxidant activity similar to those of trolox and ascorbic acid. It reduces the stable free radical diphenyl-2-picrylhydrazyl (DPPH). Bucillamine is a potent antioxidant which exerts its beneficial therapeutic activities in RA patients by metal chelation rather than by scavenging free radical species.

Vosaroxin is a small molecule and a naphthyridine analogue with antineoplastic activity. This quinolone-based topoisomerase II inhibitor is a new therapeutic for acute myeloid leukemia (AML). Being a DNA intercalating topoisomerase II inhibitor that causes the induction of apoptosis via double-strand DNA breaks vosoroxin is chemically distinct from other topoisomerase inhibitors with its stable quinolone-based core. Due to the stability of this core, vosaroxin is not associated with significant formation of toxic metabolites, free radicals, or reactive oxygen species, which are associated with off-target organ damage and cardiotoxicity. Furthermore, vosaroxin evades two common mechanisms of drug resistance, as it is not a substrate for the P-glycoprotein efflux pump and its activity is maintained in cells with p53 deletion. Vosaroxin has beeт tested in several investigator-sponsored studies, both as a single-agent and in combination with other therapies, for the treatment of AML and myelodysplastic syndromes. Both the U.S. Food and Drug Administration (FDA) and European Commission have granted orphan drug designation to vosaroxin for the treatment of AML. Additionally, vosaroxin has been granted fast track designation by the FDA for the potential treatment of relapsed or refractory AML in combination with cytarabine. Vosaroxin is an investigational drug that has not been approved for use in any jurisdiction. The trademark name QINPREZO is conditionally accepted by the FDA and the EMA as the proprietary name for the vosaroxin drug product candidate.

Epristeride is a steroid 5-alpha-reductase inhibitor developed for the treatment of prostatic hyperplasia and acne. The drug reached phase III clinical trial for hyperplasia in the UK, the US and Japan, however, the current status of the drug is unknown.

Acadesine, also known as 5-aminoimidazole-4-carboxamide-1-β-D-ribofuranoside, AICA-riboside, and AICAR, is an AMP-activated protein kinase activator which is used for the treatment of acute lymphoblastic leukemia (ALL) and may have applications in treating other disorders such as mantle cell lymphoma (MCL). The mechanism by which acadesine selectively kills B-cells is not yet fully elucidated. The action of acadesine does not require the tumour suppressor protein p53 like other treatments. This is important, as p53 is often missing or defective in cancerous B-cells. Studies have shown acadesine activates AMPK and induces apoptosis in B-cell chronic lymphocytic leukemia cells but not in T lymphocytes. Antiapoptotic proteins of the Bcl-2 family regulate MCL cell sensitivity to acadesine and combination of this agent with Bcl-2 inhibitors might be an interesting therapeutic option to treat MCL patients. Acadesine has anti-ischemic properties that is currently being studied (Phase 3) for the prevention of adverse cardiovascular outcomes in patients undergoing coronary artery bypass graft (CABG) surgery. Adenosine itself has many beneficial cardioprotective properties that may therefore be harnessed by this new class of drugs. Unlike adenosine, acadesine acts specifically at sites of ischemia and is therefore void of the systemic hemodynamic effects that may complicate adenosine therapy. Animal and in vitro studies have established acadesine as a promising new agent for attenuating ischemic and reperfusion damage to the myocardium. Acadesine also possesses the theoretical (but unproven) benefit of attenuating reperfusion injury after acute myocardial infarction (MI). Further research is needed to define the full potential of this unique agent in various clinical situations involving myocardial ischemia.

Ridaforolimus (Deforolimus, MK-8669) is an investigational oral mTOR inhibitor in development for the treatment of metastatic soft-tissue or bone sarcomas. Ridaforolimus is being co-developed by Merck and ARIAD Pharmaceuticals. Ridaforolimus (Deforolimus, MK-8669) is a selective mTOR inhibitor with IC50 of 0.2 nM in HT-1080 cell line; while not classified as a prodrug, mTOR inhibition and FKBP12 binding is similar to rapamycin. mTOR is a protein kinase that controls cell growth by regulating many cellular processes, including protein synthesis and autophagy. Compared with other mTOR inhibitors, ridaforolimus is not a prodrug and has shown in vivo stability. Both intravenous and oral formulations of the compound are being tested in clinical trials for the treatment of various solid tumors and hematologic malignancies. The initial indication is soft-tissue and bone sarcomas. Ridaforolimus was indicated to treat patients with metastatic soft tissue sarcoma or bone sarcoma whose disease has not progressed after at least 4 cycles of chemotherapy. In June 2012, Merck & Co., Inc. announced the receipt of a Complete Response Letter from the U.S. Food and Drug Administration (FDA), advising the company that the New Drug Application (NDA) for ridaforolimus had not been approved. Currently Ridaforolimus is in phase III clinical trials for the treatment of Coronary artery restenosis.

Pyridoxamine (PM) is one of three natural forms of vitamin B6. It is a critical transient intermediate in catalysis of transamination reactions by vitamin B6-dependent enzymes. In preclinical or clinical trials PM has demonstrated pharmacological potential for treatment of diabetic nephropathy, diabetic retinopathy, and hyperlipidemia, and for use in kidney stone preventive therapies. Although its precise mode of action in vivo is not yet clear, it is likely that at least three mechanisms are at play: inhibition of post-Amadori steps of the Maillard reaction; scavenging of reactive carbonyl compounds; and inhibition of toxic effects of ROS. Pyridoxamine was marketed as a dietary supplement, often as the hydrochloride salt, pyridoxamine dihydrochloride. However, in the United States, the FDA ruled in January 2009 that pyridoxamine must be regulated as a pharmaceutical drug because it is the active ingredient in Pyridorin, a drug designed to prevent the progression of diabetic nephropathy.
