Bambuterol is an active precursor of the selective beta2-adrenergic agonist terbutaline. Bambuterol is the bis-N,N-dimethyl-carbamate of terbutaline. Bambuterol is a remarkably selective and potent inhibitor of cholinesterase. BAMBEC (Bambuterol hydrochloride) oral solution or tablets are indicated for the management of asthma, bronchospasm and/or reversible airways obstruction.

(R)-Zopiclone is the (R)-enantiomer of benzodiazepine modulator Zopiclone. (S)-Zopiclone binding at benzodiazepine recognition sites is about 50-fold higher than of the (R)-zopiclone, and the pharmacokinetics of the enantiomers varies between individuals differently. In rats, there is no stereo conversion from (S)- to (R)-Zopiclone, whereas (R)-Zopiclone converts to (S)-Zopiclone, which is preferentially distributed into the brain. (R)-Zopiclone is known to have sedative and anxiolytic effects and as well as effects towards locomotor activity reduction.

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.

Glycitin (4'-Hydroxy-6-Methoxyisoflavone-7-D-Glucoside) is a soy isoflavone. Isoflavone mixtures from soybean containing glycitin exert anti-obese and antidiabetic, antineoplastic, antioxidant effects. Isoflavone supplementation in healthy males may enhance cognitive processes which appear dependent on oestrogen activation. Glycitin underwent hydrolysis of the beta-glycoside moiety and little further biotransformation, leading to high plasma glycitein concentrations.

Benzbromarone (INN) is a uricosuric agent and non-competitive inhibitor of xanthine oxidase used in the treatment of gout, especially when the first line treatment, allopurinol, fails or produces intolerable adverse effects. It is structurally related to the antiarrhythmic amiodarone. Benzbromarone was introduced in the 1970s and was viewed as having few associated serious adverse reactions. It was registered in about 20 countries throughout Asia, South America and Europe. In 2003, the drug was withdrawn by Sanofi-Synthélabo, after reports of serious hepatotoxicity, although it is still marketed in several countries by other drug companies. The withdrawal has greatly limited its availability around the world and increased difficulty in accessing it in other countries where it has never been available. Standard dosages of benzbromarone (100 mg/day) tend to produce greater hypouricaemic effects than standard doses of allopourinol (300 mg/day) or probenecid (1000 mg/day). Adverse effects associated with benzbromarone are relatively infrequent but potentially severe. Four cases of benzbromarone-induced hepatotoxicity were identified from primary literature, and eleven cases have been reported by Sanofi-Synthélabo but details are not available in the public domain. Only one of the four publicly published cases demonstrated a clear relationship between the drug and liver injury as demonstrated by rechallenge. The other three cases lacked incontrovertible evidence to support a diagnosis of benzbromarone-induced hepatotoxicity. If all the reported cases are assumed to be due to benzbromarone, the estimated risk of hepatotoxicity in Europe was approximately 1 in 17 000 patients but may be higher in Japan. Benzbromarone is a very potent inhibitor of CYP2C9. The mechanism of benzbromarone hepatotoxicity is believed to be due to its hepatic metabolism by CYP2C9 and possible effects of the parent compound or its metabolites on mitochondrial function. Benzbromarone is a benzofuran and shares structural similarities with benzarone and amiodarone, all three of which affect mitochondrial function.

Ebastine is an antihistamine which blocks H1-receptors through its carboxylic acid metabolite. Ebastine is indicated for the treatment of allergic rhinitis and chronic idiopathic urticaria.

(s)-Thalidomide is an enantiomer of immunomodulatory agent Thalidomide. Thalidomide enantiomers are converted to each other in vivo, and Thalidomide contains both left and right-handed isomers in equal amounts. (s)-Thalidomide has proven efficacy in multiple myeloma. s-thalidomide-induced apoptosis associated with increases in I-kB activity, downregulation of NF-kB activity and an increase in Bax: Bcl-2 ratio. In cells cultured with s-thalidomide, there was a four-fold downregulation of the NFkB gene that was associated with a significant decrease in its protein activity.

Gentiopicrin is a naturally occurring iridoid glycoside. It is a bioactive component of gentian species of medical plants. It has proved to be the strongest inhibitor of myeloperoxidase. It could be absorbed rapidly in mice, but with a low bioavailability, and could distribute to tissues extensively. Gentiopicrin has been reported to be effective against inflammatory conditions such as rheumatoid arthritis, liver illness, fever, digestive and intestinal disorders. Gentiopicrin treatment can exert anti-inflammatory effects on experimental acute colitis through attenuating the expression levels of TNF-α, IL-1β, IL-6, iNOS and COX-2, and it may present the therapeutic potential in the treatment of colitis. The drug inhibits reserpine-induced pain/depression dyad by downregulating GluN2B receptors in the amygdala. Gentiopicrin injection was approved by SFDA for the treatment of acute jaundice and chronic active hepatitis.

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.
