Hydroxypethidine, an opioid analgesic is an opioid receptor agonist. Hydroxypethidine is under the control of narcotic drugs according to US Single Convention 1961.

Caldaret is intracardiac calcium (Ca2+) handling modulator whose cardioprotective actions are presumed to be due to inhibition of the NCX exchanger and increasing the uptake of Ca2+ via the sarcoplasmic reticulum (SR). Unfortunately, Caldaret failed to demonstrate efficacy in Phase II clinical trials as an adjunct to standard therapy with primary percutaneous coronary intervention patients diagnosed as having an acute myocardial infarction

Cefrotil is an antibiotic drug patented by pharmaceutical company Farbwerke Hoechst A.-G. And used as pharmaceutical intermediates

Cefaloram is aminocephalosporanic acid derivative with potent antibacterial activity. Cefaloram binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall. PBPs are enzymes involved in the terminal stages of assembling the bacterial cell wall and in reshaping the cell wall during growth and division. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This results in the weakening of the bacterial cell wall and causes cell lysis

Difencloxazine is a tranquilizing agent.

Entasobulin (ZEN-012; AEZS-112) is a small molecule with several mechanisms of action, such as DNA fragmentation via inhibition of topoisomerase II as well as inhibition of tubulin polymerization. It exerts antineoplastic activity. It was being developed for the treatment of cancers.

Forfenimex (also known as forphenicinol), a low molecular weight immunomodifier was studied as an antineoplastic agent. Preclinical experiments in vitro have shown that forfenimex enhanced the antitumor effects of cyclophosphamide in a model of squamous cell carcinoma. Experiments on rodents have revealed that this compound possessed protective effect against P. aeruginosa infection. This influence achieved due to macrophage activation followed by the enhancement of the bactericidal activity of polymorphonuclear cells (PMN).

Lefradafiban, an orally active prodrug of fradafiban, is a novel glycoprotein (IIb/IIIa) inhibitor for the treatment of unstable angina. The pharmacokinetic and pharmacodynamic properties of lefradafiban were assessed in 130 healthy male volunteers who received a single dose of 10, 50, 75, 100, or 150 mg or multiple doses of 25, 50, 60, 75, 90, or 100 mg three times daily for one week. After both single and multiple doses, receptor occupancy and plasma lefradafiban levels correlated with platelet aggregation. Lefradafiban had been in phase II clinical trials by Boehringer Ingelheim for the treatment of thrombosis. However, it has been terminated.

Sornidipine, a nifedipine derivative, is a calcium channel blocker.

TAK-285 is a novel low-molecular weight compound that was designed, synthesized by Takeda Pharmaceutical Company, Osaka, Japan, and has been shown to selectively and potently inhibit HER2 and EGFR kinase activities. Biochemically, TAK-285 inhibits HER2 and EGFR phosphorylation, with 50% inhibition concentrations of 17 and 23 nmol –1, respectively. This drug was in the phase I of clinical trial for the treatment of solid rumors and cancer but was discontinued due to strategic reasons. In addition was investigated that TAK-285 is not Pgp substrates, which is why it may be useful in the development of agents with the potential to treat brain metastases.
