Pimefylline is an N-methylated xanthine derivative. It is a coronary vasodilator and muscle relaxant.

Nitromiphene (NIT; CI 628) is a triarylethylene antiestrogen shown to be effective in treatment of experimental breast cancer. Nitromiphene is one of the earliest nonsteroidal selective estrogen receptor modulators (SERMs). It is an anti-estrogen capable to translocate the estrogen receptor to the nucleus and to induce the replenishment of the cytosol receptor. Nitromiphene inhibited the uptake of [3H]-estradiol in rat whole homogenates and isolated cell nuclei tissues and the pituitary, and inhibited estradiol-induced female sexual behavior. Nitromiphene has thus been shown to suppress the growth of chemically induced and ransplantedmammary tumors in rodents. Also, Nitromiphene was shown to have potent, prolonged antiuterotropic effects in immature rats. Nitromiphene has been shown to undergo conversion to demethyl Nitromiphene (CI628M), a phenolic metabolite which had greater affinity for estrogen receptors and greater biological potency in vitro than did Nitromiphene. However, the in vivo antiestrogenic effects of Nitromiphene and demethyl Nitromiphene were similar, possibly due to facile O-demethylation of the former compound after administration.

Dibemethine is an analgesic agent.

Properidine is an isopropyl analog of pethidine that acts as opioid analgesic.

Norletimol is a Schiff base with promising anti-inflammatory properties. The time taken for elimination of 50% of the Norletimol dose in the urine was approximately five hours. As an antirheumatic agent it was tested in clinical trials in Iraq. It was used in progressive myopia in children.

Nortetrazepam is a benzodiazepine derivative, it is one of the major metabolites of tetrazepam. Nortetrazepam is a psychosedative agent.

Dabuzalgron is an orally active and selective alpha1A/1L-adrenoreceptor partial agonist, developed by Roche. In anesthetized micropigs and rabbits, dabuzalgron produced non-selective, dose-dependent increases in intraurethral and arterial blood pressures. In conscious micropigs, both agents produced dose-dependent increases in urethral tension. Dabuzalgron was investigated in a clinical study in women with stress urinary incontinence (SUI). It was demonstrated that 1.5 mg of the drug administered twice daily lead to a significantly lower mean weekly number of SUI episodes with little or no cardiovascular effect. Despite positive results, no development of the drug was reported by Roche.

Metoxepin was developed as an antiemetic, neuroleptic and antihistamine agent. This drug has never been marketed.

Emapunil acts as a selective agonist at the peripheral benzodiazepine receptor (TSPO). At the cellular level, the selective TSPO ligand XBD173 potentiated the amplitude and duration of GABA-mediated inhibitory postsynaptic currents in mouse medial prefrontal cortical neurons, which was prevented by finasteride. In animal and human trials, XBD173 produced rapid anxiolytic and anti-panic effects probably via newly synthesized neurosteroids, without producing sedation or withdrawal symptoms, and may represent a promising target for the development of fast-acting anxiolytics with a more favourable side-effect profile than benzodiazepines.
