Lobuprofen is an ester type analgesic, in which the acid moiety (ibuprofen) has peripheral analgesic activity and the alcohol moiety (mCPPol) has central analgesic activity.

Cefsumide is an antibiotic of the cephalosporin group patented by Fujisawa Pharmaceutical Co. Cefsumide 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.

Rosamaricin is a macrolide antibiotic similar to erythromycin. This compound is more effective against Gram-negative bacteria than erythromycin, especially in the prostate where rosamaricin was shown to be more concentrated than erythromycin in dogs. Rosamaricin has antibiotic activity against Neisseria gonorrhoeae, Chlamydia trachomatis, Ureaplasma urealyticum and Mycoplasma hominis. When the drug was compared with penicillin G in the treatment of pneumococcal meningitis in rabbits it was found to be less effective than penicillin G, as measured by bacterial clearance from cerebrospinal fluid and by treatment outcome. No information on the current use of this compound is available.

Lorpiprazole (brand name Normarex) is a marketed anxiolytic drug of the phenylpiperazine group. It has been described as a serotonin antagonist and reuptake inhibitor (SARI) in the same group as trazodone, nefazodone, and etoperidone.

Fenobam is a selective and potent metabotropic glutamate (mGlu)5 receptor antagonist with inverse agonist activity. Fenobam was previously investigated as an anxiolytic in a number of phase II studies in the early 1980s. These studies revealed a mixed picture of anxiolytic efficacy, with double blind, placebo controlled trials variously reporting the compound as active or inactive. This discrepancy was not easily reconciled based on patient numbers, dose level, duration of treatment, or outcome measures. The positive effects seen in animal models of fragile X syndrome (FXS) treated with fenobam or other mGluR5 antagonists, the apparent lack of clinically significant adverse effects, and the potential beneficial clinical effects seen in this pilot trial support further study of the compound in adults with FXS.

Ciclazindol is an indole derivative and monoamine uptake inhibitor patented by pharmaceutical company John Wyeth and Brother Ltd. as an antidepressant. Besides that, Ciclazindol is effective anorectic agent, inducing weight loss in rats and man. Ciclazindol was shown to inhibit ATP-sensitive K+ (K(ATP)) channel currents and stimulate insulin secretion from CRI-G1 insulin-secreting cells. The inhibition of KATP channel currents by ciclazindol is unaffected by the removal of intracellular Mg2+ ions and after trypsinization of the cytoplasmic surface of excised patches, treatments known to abolish sulphonylurea sensitivity.

Ciprefadol is an opioid analgesic drug. It binds with a high affinity to mu (Ki 4.2 nM) and kappa (Ki 2.5 nM) opioid receptors. In vivo, ciprefadol displays mixed antagonist/agonist activity in the mouse writhing and the rat tail heat tests: in low doses, the compound inhibits the analgesic effect of morphine, while at higher doses it displays analgesic effect. Chronic administration of ciprefadol to rhesus monkeys produced a marked physical dependence more severe than that of morphine, and its effect was consistent with what would be expected of a potent, long-lasting morphine-like agonist.

Naxaprostene (CG 4305) is a prostacyclin analogue, which causes concentration dependent inhibition of thrombocyte function. Naxaprostene is more selective for IP receptors and tends towards partial agonism. Naxaprostene prevented thrombotic arterial occlusion in rabbits.

Metaterol is a beta-adrenoceptor agonist. It exerts sympathomimetic and broncholytic properties.
