Danofloxacin is a quinolone antibacterial agent for veterinary medicine. The drug is approved by FDA for the treatment of bovine infectious respiratory disease under the name Advocin (mesylate salt). Danofloxacin exerts its action by inhibiting bacterial DNA gyrase.

Elobixibat is the first in class ileal bile acid transporter (IBAT) inhibitor. IBAT inhibitors block ileal absorption of bile acids by: (1) interrupting the enterohepatic circulation of bile resulting in a fall in serum cholesterol and (2) increasing the delivery of bile acids into the colon. Elobixibat stimulates both motor and secretory functions in the colon. Elobixibat is approved in Japan for the treatment of chronic constipation. Elobixibat has potential benefit in the treatment of non-alcoholic steatohepatitis.

Pixantrone is a novel anthracenedione. It is a weak inhibitor of topoisomerase II. Pixantrone directly alkylates DNA forming stable DNA adducts and cross-strand breaks. Pixuvri is approved for the treatment of adult patients with multiply relapsed or refractory aggressive Non-Hodgkin lymphomas. It is used for patients whose cancer does not respond or has returned after they have received other chemotherapy treatments. The most frequent AE were seen in the blood (mainly neutropaenia), gastrointestinal (nausea, abdominal pain, constipation) and respiratory systems (cough, dyspnea). No drug-drug interaction studies have been submitted and no drug interactions have been reported in human subjects

Evocalcet (MT-4580, KHK7580) is an allosteric calcium-sensing receptor agonist. Evocalcet directly acts on calcium receptors on parathyroid cells to suppress synthesis and secretion of parathyroid hormone (PTH), and it consequently decreases serum PTH and serum calcium. ORKEDIA® TABLETS (generic name: evocalcet, code name: KHK7580) has been listed on the National Health Insurance (NHI) Drug Price List and launched for the treatment of secondary hyperparathyroidism in patients on maintenance dialysis in Japan.

Raclopride is a salicylamide neuroleptic, that acts as a selective antagonist of D2 dopamine receptors both in vitro and in vivo. Tritium-labelled raclopride has properties that demonstrate its usefulness as a radioligand for the labelling of dopamine-D2 receptors : 3H-Raclopride has a high affinity for the rat and human dopamine-D2 receptors, the non-specific binding of 3H-raclopride is very low, not exceeding 5% of the total binding and the distribution of the 3H-raclopride binding sites in the brain closely correlates with the dopaminergic innervation. The binding of 3H-raclopride is blocked by dopamine-D2 agonists and antagonists, while the D1 agonist SKF 38393 and the Dl antagonist SCH 23390 have much less potency. The interaction of dopamine with 3H-raclopride binding results in a shallow competition curve, which suggests that 3H-raclopride, similar to other dopamine-D2 radioligands, labels both high and low agonist affinity states of the dopamine-D2 receptor. The in vivo receptor binding studies performed with 3H-raclopride also demonstrate its favorable properties as a dopamine-D2 receptor marker in vivo In contrast to some other compounds used as radioligands, raclopride enters the brain readily and binds with a low component of non-specific binding in all dopamine-rich brain areas. A saturation curve may be achieved in vivo binding studies since injections of increasing concentrations of 3H-raclopride appears to be saturated at concentrations above 25 mkCi (corresponding to approximately 5 nmol/kg). Raclopride antagonizes apomorphine-induced hyperactivity in the rat at low doses (ED50 = 130 nM/kg i.p.) but induces catalepsy only at much higher doses (ED50 = 27 mkM/kg i.p.). Radiolabelled raclopride has been used as a ligand for in vitro and in vivo autoradiography in rat and primate brains. Raclopride C 11 is used with positron emission tomography (PET) as a clinical research tool to determine dopamine type 2 (D 2) receptor density in the human brain under normal and pathological conditions. For example, raclopride C 11 used in PET studies has served to confirm the age-related decrease in striatal dopamine D2 receptor density, which may be associated with a decline in the motor as well as cognitive functions. In patients with Alzheimer's disease, raclopride C 11 may be used to examine neuroreceptor distribution and quantities, which may help in the analysis of degenerative alterations of neuron populations and neuroreceptor systems in patients with this disease. In Huntington's disease, in which degeneration of neostriatal interneurons occurs (postsynaptic to the dopaminergic input), specific binding of raclopride C 11 to D 2 receptors may serve as one of the parameters in predicting performance in cognitive tasks.

Avenanthramides are a group of phenolic alkaloids found mainly in oats, but also in butterfly eggs (Pieris brassicae and Pieris rapae), and fungal infected carnation (Dianthus caryophyllus). Avenanthramides demonstrate anti-inflammatory, antioxidant, anti-itch, anti-irritant, and antiatherogenic activities. Avenanthramide is considered the active component in a number of skin care products based on colloidal oatmeal; a traditional treatment which was approved by the FDA in 2003. Dietary supplementation with foods enriched in Avenantramides has been studied for the potential to reduce systemic inflammation. Avenanthramides have also been studied in cell models for osteoporosis and cancer.

Luseogliflozin (TS-071), a derivative of a novel scaffold, C-phenyl 1-thio-D-glucitol, exhibited potent sodium-dependent glucose cotransporter (SGLT) 2 inhibition activity. Luseogliflozin exhibits a blood glucose lowering effect, excellent urinary glucose excretion properties, and promising pharmacokinetics profiles in animals. It showed good metabolic stability toward cryo-preserved human hepatic clearance, have acceptable human pharmacokinetics properties. Luseogliflozin [Lusefi(®) (Japan)] was developed by Taisho Pharmaceutical for the treatment of patients with type 2 diabetes mellitus. The drug has received its first global approval for this indication in Japan, either as monotherapy or in combination with other antihyperglycaemic agents.

Silymarin, a plant-derived flavonoid from the plant Silybum marianum, is considered the most potential drug to treat almost all kind of liver diseases, particularly alcoholic liver disease, acute and chronic viral hepatitis and toxins-mediated liver dysfunctions. The main component of the silymarin complex is silybin, synonymous with silibinin, sometimes incorrectly called silybinin, which is a mixture of two diastereomers A and B in approximately 1:1 proportion. The drug possess hepatoprotective and antioxidant activity. The hepatoprotective effect is due to stimulation of synthesis of structural and functional proteins and phospholipids, as well as acceleration of the regeneration of hepatocytes. Antioxidant effect is determined by interaction of bioflavones with free radicals in the liver and its detoxication. In such manner the process of peroxidation of the lipids is interrupted and further liver destruction is prevented. Side effect is a mild laxative effect has occasionally been observed.

Sulpiride is an atypical antipsychotic drug (although some texts have referred to it as a typical antipsychotic) of the benzamide class used mainly in the treatment of psychosis associated with schizophrenia and major depressive disorder, and sometimes used in low dosage to treat anxiety and mild depression. Sulpiride is commonly used in Europe, Russia and Japan. Sulpiride is a selective antagonist at dopamine D2 and D3 receptors. This action dominates in doses exceeding 600 mg daily. In doses of 600 to 1,600 mg sulpiride shows mild sedating and antipsychotic activity. Its antipsychotic potency compared to chlorpromazine is only 0.2 (1/5). In low doses (in particular 50 to 200 mg daily) its prominent feature is antagonism of presynaptic inhibitory dopamine receptors accounting for some antidepressant activity and a stimulating effect. Therefore, it is in these doses used as a second line antidepressant. Racemic and L-sulpiride significantly decreased stimulated serum gastrin concentration, but they did not affect fasting serum gastrin or basal and stimulated gastric acidity. D-sulpiride significantly decreased gastric acid secretion, without affecting serum gastrin levels.
