Etibendazole (R34803 or methyl [5-(2-(4-fluorophenyl)-1,3-dioxolan-2-yl)-1H-benzimidazole-2-yl] carbamate), a benzimidazole derivative, is a microtubule inhibitor. Etibendazole exerts antihelmintic activity.

Forminitrazole was studied as an antiprotozoal and antitrichomonal agent. Information about the current use of this compound is not available.

Pirinidazole was found to be the compound from a series of 5-nitroimidazoles with the broadest action against protozoans. Its effect against trichomonads is the most pronounced. The comparison of the effective doses of different 5-nitroimidazoles against Trichomonas fetus demonstrates that the compound Pirinidazole is slightly superior to Tinidazole, distinctly superior to Metronidazole, and very much superior to Nitrimidazine. Some toxicological data of Pirinidazole show that the compound is well tolerated.

Aminoquinol (XIB4035) is a nonpeptidyl small molecule agonist for GFRalpha-1. XIB4035 concentration-dependently inhibited [(125)I]GDNF binding in Neuro-2A cells with an IC(50) of 10.4 uM. GDNF induced autophosphorylation of Ret protein, and promoted neurite outgrowth in Neuro-2A cells. XIB4035, like GDNF, induced Ret autophosphorylation in the Neuro-2A cells. Moreover, XIB4035 promoted neurite outgrowth in a concentration-dependent manner. These results show that XIB4035 may act as an agonist at GFRalpha-1 receptor complex, and mimic neurotrophic effects of GDNF in Neuro-2A cells. It has been shown that topical application of XIB4035 is an effective treatment for small-fiber neuropathy (SFN). Topical application of GFRα/RET receptor signaling modulators may be a unique therapy for SFN, and XIB4035 is a candidate therapeutic agent. Aminoquinol has been also used in the therapy of cutaneous leishmaniasis and lambliasis.

Diphenan is p-benzyl-phenyl-carbamate. Various workers have reported that diphenan will rid children of oxyurids and it has been claimed to be nontoxic and tasteless and to have the advantage of being a vermicide as opposed to a vermifuge. An attempt has been made to assess the efficacy of diphenan as a vermicide. Diphenan was given far in excess of the normal dosage. Subsequent examnation showed few cures and these mostly in lightly infested children. The condition of many was unchanged and that of some worse after treatment. No toxic reactions were encountered. Moreover, diphenan was found to have no detectable anthelmintic effect when given in high dosage in the treatment of enterobiasis.

Crufomate is an insecticide and antihelmintic drug which acts by inhibition of acetylcholinesterase. Crufomate was used on or in cattle, sheep, and goats to control internal cattle grubs and external horn flies and cattle lice. Crufomate is administered by injection, oral administration, and spraying. For the treatment of internal helminth parasites, crufomate is administered by the oral drench directly into the rumen.

Salantel was used in veterinary as an anthelmintic agent. Information about the current use of this compound is not available.

Bamnidazole was developed as an antiprotozoal agent against Tryhomonas, however, has never been marketed.

Nitroxinil is an anthelmintic drug mainly used for the control of liver fluke in sheep and cattle. Nitroxinil is active against the liver fluke the Fasciola hepatica and to a lesser extent against thread worms in the gastrointestinal tract. The efficacy of nitroxinil administered once by subcutaneous injection at a dosage regimen of 20 mg/kg live mass was evaluated against natural infestations of parafilaria bovicola in cattle. Trial animals were slaughtered 14 weeks after treatment. Treatment reduced the number of bleeding points by 97,8%, eosinophil-positive carcass lesions by 85,7% and eosinophil-positive lesion area by 92,8%, compared with controls.
