Monophosphothiamine is thiamine derivative used for the treatment of neuritis, polyneuritis, asthenic conditions (weakness), as an additional remedy for chronic blood circulation insufficiency, chronic gastritis accompanied by motor and secretory disorders functions of the stomach. Monophosphothiamine underwent metabolic phosphorylation to active metabolite thiamine pyrophosphate, that acts as a coenzyme in the different metabolic process.

Beclotiamine (or chloroethyl thiamine) had been studied for veterinary and showed anticoccidial activity against Eimeria tenella, although metabolites and related substances were inactive. Information about the nowadays application of this compound is not available.

PX-102 is a methoxyphenylcyclopropane derivative patented by Phenex Pharmaceuticals AG as Farnesoid X receptor agonists useful in the treatment and prophylaxis of FXR-mediated diseases. The Farnesoid X Receptor (FXR) is a bile acid receptor which when activated by Px-102 has a profound positive impact on cholesterol, triglyceride and glucose metabolism in liver and intestine. In preclinical studies, Px-102 potently reduces intestinal uptake of neutral lipids and cholesterol and at the same time enhances the excretion of these lipid species. In addition, Px-102 improves hepatic insulin sensitivity and shows massive hepatoprotective effects in animal models of liver cirrhosis or fibrosis. Phenex Pharmaceuticals completes a phase I trial in Healthy volunteers in Germany in 2012 and no further development report has been published.

GSK-2269557 (nemiralisib), a PI3Kδ inhibitor, is in development as an anti-inflammatory drug for the treatment of inflammatory airways disease. Studies in moderate or severe stable COPD patients have shown an acceptable safety and tolerability profile when GSK-2269557 was administered via inhalation. Cough was the most commonly reported adverse event.

Transcrocetinate (TSC) is a novel compound that offers promise as a treatment for conditions caused by hypoxia or ischemia. Unlike crocetin, it worked well in the more severe hemorrhagic shock model. Although many of the earlier studies with TSC involved the treatment of the ischemic conditions of hemorrhagic shock in both rats and swine, a few other studies involved treating purely hypoxic situations. One study showed that TSC was capable of promoting survival in rats breathing 10% oxygen. TSC also was able to increase arterial PO2 values in a rat model of acute respiratory distress syndrome (ARDS) caused by injection of oleic acid. The drug acts via a mechanism that has not been previously exploited in a pharmaceutical. TSC increases the rate of oxygen diffusion between the erythrocytes and the tissues by altering the 'structure' of water in blood plasma. It does this by causing additional hydrogen bonds to form among the water molecules. Animal toxicology studies have demonstrated that high levels of TSC are well-tolerated, and a Phase I clinical study has shown that TSC is also safe in humans. Delayed TSC treatment improves outcomes in experimental models of both ischemic and hemorrhagic stroke. TSC may be a safe and beneficial therapeutic modality for early stroke intervention, irrespective of the type of stroke involved. Transcrocetinate is in phase III clinical trial for the treatment of glioblastoma.

Menadiol sodium sulfate is a metabolite of one of the forms of vitamin K4, which was found in a biofluid of rodents.

AEOL-10150 is a small-molecule antioxidant developed by Aeolus (formerly Incara) for potential subcutaneous treatment for amyotrophic lateral sclerosis (ALS), stroke, spinal cord injury, lung inflammation, and mucositis. Structurally, AEOL-10150 functions as a superoxide-dismutase mimic and contains metalloporphyrin moiety. AEOL-10150 possess high superoxide-dismutase activity as well as catalase-like activity and has the capacity to scavenge peroxynitrite and lipid peroxides. In 2017 Aeolus Pharmaceuticals has announced that the FDA has granted Fast Track designation to AEOL 10150 for the prevention of fatal respiratory failure among patients at risk for radiation pneumonitis following a radiological/nuclear incident sufficient to cause the Acute Radiation Syndrome.

Carbovir is a nucleoside reverse transcriptase inhibitor analog of guanosine. Carbovir decreases HIV viral loads, retards or prevents the damage to the immune system, and reduces the risk of developing AIDS. Carbovir Triphosphate belongs to the class of organic compounds known as nucleoside and nucleotide analogues. These are analogues of nucleosides and nucleotides. Carbovir interferes with the enzyme HIV uses to manufacture new viral particles within an infected cell, and is primarily metabolized to the 5'-triphosphate of Carbovir (CBV-TP) to concentrations sufficient to inhibit HIV reverse transcriptase.
