Clometocillin, one of the forms of penicillin, was active against pen-I or pen-R pneumococci and was used in children. The modern information about its application is not available.

Cyclobutyrol (CB) is a choleretic agent, which also inhibits biliary lipid secretion. Administration of cyclobutyrol reduced biliary concentration and output of cholesterol and phospholipid. This is due to an uncoupling of the secretion of cholesterol and phospholipids from that of bile acids. Biliary outputs of the canalicular membrane enzymes 5'-nucleotidase and alkaline phosphodiesterase I are depressed. The most likely effect of CB is exerted at the level of the canalicular membrane.

Hopantenic acid (homopantothenic acid) is a central nervous system depressant. Formulated as the calcium salt, it is used as a pharmaceutical drug in the Russian Federation under the brand name Pantogam. In Russia it is widely used to treat a variety of neurological, psychological and psychiatric conditions. The drug has been on the pharmaceutical market since 1979 and has been proven to be safe even for children from 3 years old upwards. Hopantenic acid is a natural forming substance, has some of the lowest side effects and considered to be very safe. Use Pantogam to treat a wide variety of cognitive and nervous system disorders with combined sedative and mild stimulant effect. Hopantenic acid is not approved for use in Europe or the United States. GABA receptor agonist.

Cloricromen a drug that inhibits platelet aggregation in man and in experimental thrombosis. Experiments on rodents have revealed that cloricromene which reduced tumor necrosis factor production, could be useful in the treatment of periodontitis. In addition, it could be potentially useful in ischemic-retinal diseases where amelioration of blood flow and inflammation is desirable. However, experiments with patients with cerebrovascular occlusive disease didn’t shown any effect of cloricromen on coagulative variables.

THALLOUS OXIDE (Thallium (1) Oxide) has been used in the manufacturing of glass of a high coefficient of refraction for optical purposes (thallium flint glass) and for artificial gems. Thallium oxide is black in color and is the inorganic compound of Thallium and Oxygen. THALLOUS OXIDE compounds are typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics (e.g. tablets) and in light weight structural components in aerospace and electrochemical applications such as fuel cells. THALLOUS OXIDE is toxic by ingestion. It has previously been used as rat poison and ant killer, but its use is prohibited since 1972.

Potassium Trihydrogen Dioxalate is a Potassium salt used in photography, marble grinding, and in metal polishing. Potassium Trihydrogen Dioxalate is strongly irritating to eyes, mucous and gastrointestinal tract. Potassium Trihydrogen Dioxalate may cause cardiac failure and death after oral administration

Efonidipine is a 1,4-dihydropyridine derivative for the treatment of hypertension and angina. Efonidipine exerts its antihypertensive and antianginal effects through blocking L- and T-type calcium channels.

Diamminedichlorodihydroxyplatinum IV is the platinum-based antineoplasticis agent. Oxaliplatin is cis, cis, trans- isomer of Diamminedichlorodihydroxyplatinum IV. Oxaliplatin show high stability and therefore can be utilized orally for outpatient care. Although oxoplatin is capable of binding directly to DNA after prolonged incubation, platinum(IV) agents are considered to be largely inert prodrugs that are converted to highly cytotoxic platinum(II) compounds by reducing substances, enzymes, or microenvironmental conditions. Reaction of oxoplatin with 0.1 M hydrogen chloride mimicking gastric acid yields cis-diammine-tetrachlorido-platinum(IV) (DATCP[IV]), which exhibits two-fold increased activity. The oxoplatin metabolite DATCP(IV) constitutes a potent cytotoxic derivative that may be produced by gastric acid or acidic areas prevailing in larger solid tumors, depending on the respective pharmaceutical formulation of oxoplatin.

MK-0752 is a potent, reversible inhibitor of γ-secretase, which inhibits γ-secretase to cleave substrates such as amyloid precursor protein. MK-0752 shows promising effects on inhibiting the growth of several types of cancer cells and was investigated in clinical trials for cancer treatment. For example in ovarian cancer models MK-0752 alone actively induced cell growth inhibition, G2/M phase cell cycle arrest and apoptosis with down-regulation of Notch1 and its downstream effectors in a dose- and time-dependent manner. Moreover, the sequential combination of cisplatin prior to MK-0752 significantly promoted cell apoptosis and inhibited the subcutaneous xenograft growth of ovarian cancer in nude mice. Through its effects on the Notch pathway, MK-0752 reduces the number of breast cancer stem cells in tumorgrafts, enhancing the efficacy of the chemotherapy drug docetaxel in mice with breast cancer tumors. Unfortunately, in phase II clinical trials MK-0752 failed to demonstrate efficacy.

Lercanidipine is antihypertensive drugs which acts by blocking L-type calcium channels, allowing relaxation and opening of blood vessels. Lercanidipine exists as a racemate, with anti-hypertensive activity residing primarily in S-enantiomer. NDA for lercanidipine was submitted to FDA in 2002 by Forest Laboratories, but FDA refused to approve the drug, and lercanidipine is not marketed in USA. Lercanidipine is also investigated in preclinical models of epilepsy and ischemic stroke.
