Nifuroxazide is a nitrofuran antibiotic used for the treatment of acute infectious diarrhoea.Nifuroxazide is a potent inhibitor of Signal transducers and activators of transcription (STAT) signaling. It exerts antineoplastic potential both in vitro and in vivo.

Gabexate is a synthetic protease inhibitor, was shown to be effective in treating patients with sepsis-associated disseminated intravascular coagulation in which tumor necrosis factor-alpha (TNF-alpha) plays a critical role. Gabexate mesylate is a drug marketed only in Italy and Japan and it is considered an essential drug in the treatment of acute pancreatitis. Gabexate is marketed under the brand name REMINARON among others in Japan. It relieves inflammatory symptoms in the pancreas by inhibiting various enzymes. It also improves organ disorders and bleeding tendency caused by blood clots in blood vessels by inhibiting blood coagulation. It is usually used to treat acute pancreatitis with deviation of proteolytic enzymes (such as trypsin, kallikrein and plasmin), acute exacerbation of chronic recurrent pancreatitis, acute pancreatitis after surgery and disseminated intravascular coagulation.

Alfatradiol (17a-estradiol, Ell-Cranell® alpha) is a stereoisomer of the female hormone 17b-estradiol. It inhibits the conversion of testosterone to the metabolite dihydrotestosterone (DHT) by suppressing 5a-reductase activity. In addition, by inhibiting 17b-dehydrogenase, it impedes the conversion process of androstenedione to testosterone, resulting in a reduction in the syntheses of testosterone and DHT. It also accelerates the conversion of testosterone to estradiol by stimulating aromatase, decreasing the level of testosterone and leading to a reduction in DHT. In addition, alfatradiol (17a-estradiol) has been reported to stimulate the generation of hair follicular matrix cells.

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.

Rilmenidine (brand names Albarel, Hyperium, Iterium and Tenaxum) is an imidazoline derivative used for the treatment of hypertension. Rilmenidine, an oxazoline compound with antihypertensive properties, acts on both medullary and peripheral vasomotor structures. Rilmenidine shows greater selectivity for imidazoline receptors than for cerebral alpha2-adrenergic receptors, distinguishing it from reference alpha2-agonists. Rilmenidine is as effective in monotherapy as all other first line classes of drugs, including diuretics, beta-blockers, angiotensin converting enzyme (ACE) inhibitors, and calcium antagonists. It is well tolerated and can be taken in combination for greater efficacy. Sedation and dry mouth are not prominent side effects and withdrawal hypertension is not seen when treatment is stopped abruptly. In addition to a reduction in blood pressure, Rilmenidine has been shown to improve glucose tolerance, lipid risk factors, and insulin sensitivity.

Melperone is an antipsychotic drug which is used in Europe for the treatment of sleep disorders, agitation and confusion states. The exact mechanism of melperone action is unknown.

(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.

Ripasudil (K-115) is a selective Rho-associated coiled coil-containing protein kinase (ROCK) inhibitor. This compound, which was originally discovered by D. Western Therapeutics Institute, Inc., reduces intraocular pressure (IOP) by directly acting on the trabecular meshwork, thereby increasing conventional outflow through the Schlemm's canal. As a result of this mechanism of action, ripasudil may offer additive effects in the treatment of glaucoma and ocular hypertension when used in combination with agents such as prostaglandin analogues (which increase uveoscleral outflow) and β blockers (which reduce aqueous production). GLANATEC® (Ripasudil hydrochloride hydrate) ophthalmic solution 0.4% is launched in Japan for the treatment of glaucoma and ocular hypertension.

Dextramycin ((S, S)-p-Chloramphenicol) is an optical isomer of Chloramphenicol, a broad-spectrum antibiotic with historical veterinary use in all major food-producing animals. The drug is biosynthesized by the soil organism Streptomyces venezuelae and several other actinomycetes and is chemically synthesized for commercial use. Chloramphenicol occurs in the meta-configuration and in the para-configuration and it contains two chiral centers thus in total eight different isomeric configurations exist. All para-stereoisomers are biologically active and 0.5% solution of Dextramycin shows antimicrobial activity. Currently, Chloramphenicol has banned for use in all food-producing animals.
