Glicondamide is a derivative of sulphonamides (antibacterial sulfa drugs). It acts by increasing the release of insulin from pancreatic beta cells, resulting in lower blood glucose levels.

Dexpemedolac is long-acting non-narcotic analgesic. Dexpemedolac exhibited potent analgesic effects against chemically induced pain in rats and mice and against inflammatory pain in rats. Dexpemedolac differed from standard nonsteroidal anti-inflammatory drugs (NSAIDs) in that the doses, which produced analgesia were much lower than those required for either anti-inflammatory or gastric irritant effects. The common to the NCAIDs class actions are antipyresis and inhibitory effects on platelet aggregation. In yeast-induced hyperthermic rats, dexpemedolac exhibited antipyretic actions, whereas the drug did not affect body temperature in normothermic animals. Aggregation of human platelets was inhibited by high concentrations of dexpemedolac.

Fencibutirol is alpha-cyclohexylbutyric acid derivative. It exerts choleretic activity.

Alvespimycin (17-desmethoxy-17-N,N-dimethylaminoethylamino-geldanamycin) (17-DMAG; NSC 707545) is an inhibitor of the molecular chaperone heat shock protein HSP90. Alvespimycin is a derivative of antineoplastic benzoquinone antibiotic geldanamycin. Alvespimycin binds to HSP90, a chaperone protein that aids in the assembly, maturation and folding of proteins. Subsequently, the function of Hsp90 is inhibited, leading to the degradation and depletion of its client proteins such as kinases and transcription factors involved with cell cycle regulation and signal transduction. Alvespimycin was studied in clinical trials for the treatment of solid tumors and hematologic malignancies however its development was discontinued.

Ondelopran (also known as LY2196044) was developed as orally available opioid receptor antagonist for the treatment of alcoholism. This drug completed clinical trials phase III where was assess its efficacy and safety in the treatment of alcohol dependence in adult outpatients.

IRLOXACIN, a fluorinated quinolone derivative, is an antibacterial agent with proved activity against both gram-positive and gram-negative bacteria.

Pirenperone, a quinazoline derivative, is a selective antagonist at serotonin receptor 2A binding sites. The liposoluble compound pirenperone has been studied in a variety of behavioral tests including the sensitive d-lysergic acid diethylamide (LSD) cue discrimination assay, in which it served as a potent LSD-antagonist. Pirenperone also proved to be an effective antagonist of serotonin-mediated behavioral responses including the head twitch response thought to be mediated by serotonin receptors.

Goxalapladib (SB-677116) is a selective inhibitor of Lipoprotein associated phospholipase A2 (Lp-PLA2).

Pentisomide is an agent structurally related to disopyramide. Pentisomide is a class-I antiarrhythmic agent with a marked effect on depolarization (action of class Ia and Ic) and on repolarization. Pentisomide dose-dependently inhibited ischaemia-reperfusion arrhythmia. Pentisomide had been in phase II clinical trial for the treatment of arrhythmias. The electrophysiologic effects of pentisomide were investigated after intravenous and oral application in patients with drug refractory atrioventricular nodal tachycardia and patients with orthodromic atrioventricular re-entrant tachycardia. If intravenous pentisomide did not prevent induction of the tachycardia, oral pentisomide was not effective either. Long-term treatment with pentisomide had to be discontinued because of possible side effects.
