Tiomergine is an ergot alkaloid derivative. It is the agonist of the postulated presynaptic dopamine receptor. Tiomergine is the antiparkinsonian agent. Tiomergine modified brain glucose metabolism in a way similar to the neuroleptics but different from postsynaptic agonists. It was ineffective in the treatment of tardive dyskinesia.

Metoserpate (SU9064) is a sedative drug used in veterinary. PACITRAN (metoserpate hydrochloride) is indicated as a tranquilizer in stressed poultry.

Dimesone is a synthetic glucocorticoid with anti-inflammatory and anti-allergic activity.

Hyodeoxycholic acid, also known as HDCA, is a secondary bile acid. Natural 6alpha-hydroxylated bile acids are receptor-specific activators of nuclear liver X receptor alpha (LXRalpha), a nuclear receptor regulating the expression of the cholesterol 7alpha-hydroxylase gene. AHRO-001 (Hyodeoxycholic acid) is in phase I clinical trials for the treatment of atherosclerosis. Through a complex signaling processes utilizing LXR receptors, the compound is designed to increase the efficiency of cholesterol efflux using the HDL cells, which act on all cholesterol in the arterial circulation as well as in the lipid core of plaque deposits in the artery walls. Use of AHRO-001 has shown no adverse effects on morbidity, mortality or toxicity and has been well tolerated at high doses.

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.

Cicloxolone is a broad spectrum antiviral agent with a largely non-specific and complex mode of antiviral action. The drug was active during all stages of the virus replication cycle, indicating that it does not operate by the specific inhibition of any single essential virus gene product. The drug reduced the number of vesicular stomatitis virusparticles assembled and released by 100- to 1000-fold. Infectious virus yield was reduced 1000- to 10000-fold, giving a 10-fold or greater increase in the particle/p.f.u. ratio. The reduced number of virus particles produced in the presence of Cicloxolone results from two superimposed effects: suppression of vesicular stomatitis virussecondary transcription and viral protein synthesis, and perturbation of virion assembly.

Clogestone Acetate (AY-11440) is a steroidal progestin that was synthesized in 1964 and was investigated as a progestin-only contraceptive but was never marketed.

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.
