Hematoporphyrin (Photodyn), a porphyrin prepared from hemin, is used as a photosensitizer in photodynamic therapy. Photodynamic therapy is based on the use of light-sensitive photosensitizers. Photoactivation causes the formation of singlet oxygen, which produces peroxidative reactions that can cause cell damage and death. Hematoporphyrin was used as the therapeutic agent in patients with manic-depressive reactions and in patients with involutional melancholia. One of the last studies has shown, that Hematoporphyrin-Photodynamic therapy (PDT) combined with stent placement is an effective and safe treatment for extrahepatic cholangiocarcinoma (EHCC).

Mitiglinide is a drug for the treatment of type 2 diabetes currently marked under tradename Glufast. Glufast® is available as the tablet for oral use, containing 5 mg or 10 mg of Mitiglinide calcium hydrate. The recommended dose is 10 mg three times daily just before each meal (within 5 minutes). Mitiglinide was approved by Pharmaceuticals and Medical Devices Agency of Japan (PMDA) on January 29, 2004, and is currently co-marketed in Japan by Kissei and Takeda. Mitiglinide is a rapid-acting insulin secretion-stimulating agent, its belongs to the meglitinide (glinide) class of blood glucose-lowering drugs. Mitiglinide is thought to stimulate insulin secretion by closing the ATP-sensitive K(+) (K(ATP)) channels in pancreatic beta-cells.

Mazaticol is an anti-acetylcholine agent used in Japan for the treatment of Parkinson's syndrome.

Orazamide, which is composed of one molecule of 5-aminoimidazole-4-carboxamide (AICA), one molecule of orotic acid and two molecules of water, is used clinically for the treatment of hepatitis and cirrhosis The nucleoside of AICA (AICAR) is internalized and becomes phosphorylated by adenosine kinase to form AICAR mono-phosphate (AICA ribotide, ZMP), an intermediate in the late steps of de novo purine biosynthesis. In hepatocytes, AICA can inhibit the fatty acid synthesis, sterol synthesis, and gluconeogenesis.

Ozagrel is a thromboxane A2 synthesis inhibitor used for the treatment of cerebral vasospasm and asthma due to its antiplatelet and anti-inflammation properties.

Incadronate (Disodium Cycloheptylaminomethylene diphosphate) is used to treat malignancy-associated hypercalcemia (MAH) in Japan. Experiments on rodents have revealed that this drug could be an effective agent for the treatment of various arthritic conditions, including human rheumatoid arthritis. In addition was shown, that incadronate induced growth inhibition and apoptotic death of pancreatic cancer cells. Incadronate also inhibited migration presumably by preventing the activation of Rho by lysophosphatidic acid. Thus, this drug can be of value in regimens for the treatment of pancreatic cancer.

Hippuric Acid is an acyl glycine produced by the conjugation of benzoic acid and glycine, found as a normal component in urine as a metabolite of aromatic compounds from food. Increased urine hippuric acid content may have antibacterial effects. Hippuric Acid is used therapeutically in the form of its salts (hippurates of calcium and ammonium). It is an ingredient of FDA-approved drug Hiprex (methenamine hippurate tablets USP). Each yellow capsule-shaped tablet of Hiprex contains 1 g Methenamine Hippurate which is the Hippuric Acid Salt of Methenamine (hexamethylene tetramine). The tablet also contains inactive ingredients. Hiprex (methenamine hippurate tablets USP) has antibacterial activity because the methenamine component is hydrolyzed to formaldehyde in acid urine. Hippuric acid has some antibacterial activity and also acts to keep the urine acid. The drug is generally active against E. coli, enterococci and staphylococci. Enterobacter aerogenes is generally resistant. The urine must be kept sufficiently acid for urea-splitting organisms such as Proteus and Pseudomonas to be inhibited. Hiprex is indicated for prophylactic or suppressive treatment of frequently recurring urinary tract infections when long-term therapy is considered necessary.

Disodium iminodiacetate is a salt of iminodiacetic acid (IDA). The iminodiacetate anion can act as a tridentate ligand to form a metal complex with two, fused, five-membered chelate rings. Iminodiacetic acid is used to diagnose problems of the liver, gallbladder and bile ducts in an imaging procedure, called as hepatobiliary iminodiacetic acid (HIDA) scan. A nuclear medicine scanner tracks the flow of the tracer from the liver into the gallbladder and small intestine and creates computer images. In addition, iminodiacetate is a part of the iminodiacetate-modified poly-L-lysine dendrimer (IMPLD), a fluorescent bone-imaging agent. IMPLD is used in the diagnosis of bone tumors, or to be used for the delivery of chemotherapy drugs or therapeutic agents. Bones differ from other body tissues in their unique calcium mineral composition, which consists mainly of hydroxyapatite (HA). IDA functionalization could be used as a general approach to bone targeting by increasing affinity for HA, enabling the transport of other molecules or particles to bones.

Dexibuprofen, S(+)-ibuprofen, is a non-steroidal anti-inflammatory drug and active dextrorotatory enantiomer of ibuprofen. Pharmacotherapeutic effects of dexibuprofen are more potent with lesser side effects than that of the racemic mixture of both isomers. In the acute and chronic treatment of osteoarthritis, it exhibits equivalent efficacy and tolerability as that of celecoxib. Dexibuprofen is a non-selective inhibitor of cyclooxygenase (COX), which is an enzyme involved in prostaglandin (mediators of pain and fever) and thromboxane (stimulators of blood clotting) synthesis via the arachidonic acid pathway. Dexibuprofen is a non-selective cyclooxygenase inhibitor and hence, it inhibits the activity of both COX-1 and COX-2. The inhibition of COX-2 activity decreases the synthesis of prostaglandins involved in mediating inflammation, pain, fever, and swelling while the inhibition of COX-1 is thought to cause some of the side effects of Dexibuprofen including GI ulceration. The major disadvantage of dexibuprofen is its low bioavailability, the account of its low solubility in physiological media.

Pirisudanol is the succinic acid ester of pyridoxine (a form of vitamin B6) and of deanol that has been used in Europe in the treatment of mild cognitive impairment as well as fatigue and depression.
