Motexafin lutetium is pentadentate aromatic metallotexaphyrin with photosensitizing properties patented by Pharmacyclics, Inc. as anticancer agent that enhances the cytotoxic potential of photodynamic therapy through several mechanisms, including depleting intracellular reducing metabolites that are necessary for repairing the oxidative damage induced by irradiation. Motexafin lutetium catalyzes the oxidation of intracellular reducing metabolites such as ascorbate, glutathione, nicotinamide adenine dinucleotide phosphate, and protein thiols, generating reactive oxygen species in a process known as futile redox cycling. The depletion (through oxidation) of these reducing metabolites removes the substrate necessary in a cell to repair oxidative damage induced by photodynamic therapy and, left unrepaired, such oxidative DNA damage is converted into lethal double-stranded breaks. Motexafin lutetium has the potential to combine the features of selective localization, ability to be activated by deeply penetrating far-red light, low incidence of skin photosensitization and water solubility. The product was in clinical development as a treatment for several types of solid tumors (as Lutrin), age-related macular degeneration (as Optrin), atherosclerosis and prevention of restenosis (as Antrin).

PBT-1033, also known as PBT-2, is a neural protective agent potentially for the treatment of Alzheimer's disease and Huntington's Disease. PBT-1033 is a moderate-affinity 8-hydroxyquinoline transition metal-ligand that acts as a synthetic chaperone, re distributing copper, zinc, and iron from locations where they are abundant to subcellular locations where they might be deficient. Delivery of copper and zinc by PBT-1033 into the cytoplasm deactivates the kinase glycogen synthase kinase 3β and the phosphatase calcineurin, both potential targets for Huntington’s disease. In aged wild-type mice, PBT-1033 improves cognitive ability and markers of neuronal plasticity and function. In Alzheimer’s disease mouse models, PBT-1033 inhibits the accumulation of amyloid β, attenuates neuropathological effects of amyloid β, including amyloid-β-induced hyperphosphorylation of tau, and improves cognition. In a 12-week, phase 2a, randomized, double-blind, placebo-controlled trial in 78 individuals with mild Alzheimer’s dementia, PBT-1033 was safe and well tolerated and significantly reduced concentrations of amyloid β42 in CSF.

Trigonellamide (1-Methylnicotinamide) is a metabolite of nicotinamide and is produced primarily in the liver by nicotinamide N-methyltransferase. Trigonellamide may be an endogenous activator of prostacyclin (PGI2) production and thus may regulate thrombotic as well as inflammatory processes in the cardiovascular system. The mechanisms of action of Trigonellamide involve the activation of PGI2 release driven by cyclooxygenase 2 (COX-2). PGI2 releasing capacity of 1- Trigonellamide was shown to afford not only anti-thrombotic but also fibrinolytic, anti-inflammatory and gastroprotective effects. Interestingly, Trigonellamide did not directly either affect the activity of leucocytes or release PGI2 in the perfused rat hindquarters model. Still, Trigonellamide, due to its PGI2 releasing capacity, might serve as a hepatoprotective agent that protects against Concanavalin-A induced liver injury through the downregulation of interleukin-4 (IL-4) and tumor necrosis factor-α signalization (TNF-α). In addition to its anti-platelet, anti-thrombotic and anti-inflammatory activities, 1-MNA has also been shown to restore endothelial function in diabetic hyperglycemic rats, as well as to improve endothelial function in humans. PGI2 displays anti-metastatic activity, and the PGI2 releasing activity of Trigonellamide, the potential application of exogenous Trigonellamide to prevent metastatic cancer.

PBI 4050, a synthetic analog of a medium-chain fatty acid that displays agonist and antagonist ligand affinity toward GPR40 and GPR84, that was developed for managing inflammatory and fibrosis-related diseases. In addition, PBI-4050 may exert antifibrotic activity in the liver through a novel mechanism of action involving modulation of intracellular ATP levels and the LKB1/AMPK/mTOR pathway in stellate cells. This drug participated in clinical trials for the treatment of acute lung injury, cystic fibrosis, diabetic nephropathies; idiopathic pulmonary fibrosis; metabolic syndrome; scleroderma; type 2 diabetes mellitus. Besides, this drug has granted a Rare Pediatric Disease Designation for the treatment of Alström syndrome (AS). PBI-4050 was also previously granted Orphan Drug Designation by the FDA and the EMA for the treatments of AS and idiopathic pulmonary fibrosis (IPF) as well as PIM (Promising Innovative Medicine) designation by the Medicines and Healthcare products Regulatory Agency (MHRA) for the treatment of IPF and AS. The FDA grants Rare Pediatric Disease Designations for serious or life-threatening diseases wherein the serious or life-threatening manifestations primarily affect individuals aged from birth to 18 years, including age groups, often called neonates, infants, children, and adolescents. Now Prometic Life Sciences plans to file investigational new drug application for pivotal phase III trial for Alstrom's syndrome in the second half of 2019.

Ravatirelin is a thiazolyl-alanine derivative patented by Japanese pharmaceutical company Shionogi & Co., Ltd. as a thyrotropin-releasing compound with improved central nerve activating effects such as sustained acetylcholine-releasing effect, and spontaneous motility increasing effect. Rovatirelin binds to the human thyrotropin-releasing hormone receptor with nanomolar affinity and increases the spontaneous firing of action potentials in the acutely isolated noradrenergic neurons of rat locus coeruleus. In in vivo studies, oral administration of Ravatirelin increased both c-Fos expression in the LC and extracellular levels of noradrenaline in the medial prefrontal cortex of rats. Furthermore, Ravatirelin increased locomotor activity. The increase in noradrenaline level and locomotor activity by Ravatirelin was more potent and longer acting than those by taltirelin. In phase I studies in healthy adult males, Ravatirelin exhibited linear pharmacokinetics in a single-ascending dose (0.1 to 10 mg) and a benign safety profile supportive of once-daily oral administration. From results of Phase II and III studies to evaluate the efficacy and safety of Ravatirelin in spinocerebellar degeneration patients, a daily dose of 1.6 to 3.2 mg of Ravatirelin has been considered to be dosage level intended for clinical use as once-daily oral administration.
