Iodoalphionic acid is the contrast medium, which was used for gallbladder examination. It is rarely appeared in the colon and, therefore, rarely masked the gallbladder. The density of the shadow produced by Iodoalphionic acid was greater than that produced by iodophthalein. It was reliable peroral cholecystographic medium, which was less objectionable to take and seldom causes vomiting. Diarrhoea occurred in some cases, but not more often than with tetraiodophenolphthalein. The ingestion of Iodoalphionic acid resulted in low thyroidal radioiodine accumulation for periods ranging from a few weeks to many months.

Ecabet is an anti-ulcer agent, marketed in Japan as an oral agent for treatment of gastric ulcers and gastritis. Ecabet eradicates Helicobacter pylori infection in gastric ulcer patients. Antibacterial effect of ecabet is demonstrated at low pH, is mediated by inhibition of bacterial urease and accompanied by interference with TLR4 signaling and pepsin inhibition. Ecabet is also investigated for the treatment of dry eye syndrome.

Oteracil is an adjunct to antineoplastic therapy, used in combination with Gimeracil and Tegafur. Gimeracil/oteracil/tegafur combination is approved for the gastric cancer treatment. Oteracil is an orotate phosphoribosyltransferase (OPRT) inhibitor that decreases the activity of 5-fluorocil (tegafur is a prodrug of 5-fluorocil) in normal gastrointestinal mucosa.

Piribedil is an antiparkinsonian agent which acts as D2 and D3 receptor agonist. In European countries and worldwide it is used as a monotherapy or in combination with dopatherapy for treatment of Parkinson's disease, cognitive impairment and obliterating arteriopathy.

Sultosilic acid is a benzenesulfonate ester. Sultosilic acid has been shown to be a hypolipidaemic drug both in animal experiments and in human clinical studies, chemically unrelated to other such drugs. The compound is being developed as a human drug (Mimedran ®) and is formulated as the piperazine salt (A-585). The recommended daily dose is three times one tablet containing 500 mg of Sultosilic acid.

Acedoben (4-acetamidobenzoic acid) is a benzoic acid derivative and a metabolite of benzocaine. It is a component of immunomodulatory drug inosine pranobex, which is used to treat mucocutaneous infections due to herpes simplex virus (type 1 and/or type II), genital warts as adjunctive therapy to podophyllin or carbon dioxide laser, and subacute sclerosing panencephalitis.

Atosiban (brand name Tractocile) is a competitive antagonist of human oxytocin at receptor level. In rats and guinea pigs, atosiban was shown to bind to oxytocin receptors, to decrease the frequency of contractions and the tone of the uterine musculature, resulting in a suppression of uterine contractions. Atosiban was also shown to bind to the vasopressin receptor, thus inhibiting the effect of vasopressin. Tractocile is indicated to delay imminent pre-term birth in pregnant adult women with: − regular uterine contractions of at least 30 seconds duration at a rate of ≥ 4 per 30 minutes − a cervical dilation of 1 to 3 cm (0-3 for nulliparas) and effacement of ≥ 50% − a gestational age from 24 until 33 completed weeks − a normal foetal heart rate. Atosiban does not have U.S. Food and Drug Administration (FDA) approval for use in the United States.

Nafamostat mesilate (NM), a synthetic serine protease inhibitor, has anticoagulant and anti-inflammatory properties. Nafamostat is approved and marketed in Japan. It relieves symptoms such as pain due to inflammation of the spleen. It improves visceral disorders and bleeding tendency caused by blood clotting tendency in the vessels. It prevents coagulation in the blood circuit during hemodialysis. It is usually used to improve acute symptoms of pancreatitis (acute pancreatitis, acute exacerbation phase of chronic pancreatitis, post-operative acute pancreatitis, acute pancreatitis after pancreatography, traumatic pancreatitis) and to prevent disseminated intravascular coagulation (DIC) and clotting of perfusing blood in extracorporeal blood circuit. Nafamostat mesilate significantly inhibits the release of platelet beta-thromboglobulin (beta TG) at 60 and 120 min. Nafamostat mesilate (NM) prevents any significant release of neutrophil elastase; at 120 min, plasma elastase-alpha 1-antitrypsin complex is 0.16 mg/mL in the NM group and 1.24 mg/mL in the control group. Nafamostat mesilate completely inhibits formation of complexes of C1 inhibitor with kallikrein and FXIIa.

There is not much available information about meralein. It was mentioned, that this compound was used as a topical anti-Infective agent.

Suramin is an antiprotozoal and anthelmintic compound. It is indicated for the treatment of African trypanosomiasis (African sleeping sickness; trypanosome fever) and Onchocerciasis (river blindness). Additionally, suramin exhibits antineoplastic action. It was discovered that suramin produced dramatic, but transient, improvement of core symptoms of autism spectrum disorder.
