Butaclamol is an antipsychotic drug, which was studied for the treatment of schizophrenia. This drug has never marketed and now is used in research, because of its action as a dopamine receptor-blocking agent. Butaclamol consists of the two forms: (-)-butaclamol, an inactive drug and (+)-butaclamol, a potent neuroleptic drug.

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.

Amedalin (UK-3540) is a selective norepinephrine reuptake inhibitor developed in the 1970s. Amedalin was a potential antidepressant compound. It has no significant effect on reuptake of serotonin and dopamine and no antihistamine or anticholinergic properties. This drug was never marketed.

Teroxirone is a triazene triepoxide patented by Shell Internationale Research Maatschappij NV as an antineoplastic agent. Teroxirone alkylates and cross-links DNA, thereby inhibiting DNA replication. Teroxirone has good cytotoxic activity against sublines of P388 and L1210 leukemias resistant to another alkylating agent. In preclinical trials, Teroxirone shows potent antineoplastic activity against murine tumors. In clinical trials, Teroxirone shows good anticancer activity and high rate of adverse events including nausea, vomiting, and myelosuppression.
