  • The use of albendazole and mebendazole, i.e., benzimidazole broad-spectrum anthelmintics, in treatment of parasitic infections, as well as cancers, is briefly reviewed. These drugs are known to block the microtubule systems of parasites and mammalian cells leading to inhibition of glucose uptake and transport and finally cell death. Eventually they exhibit ovicidal, larvicidal, and vermicidal effects on parasites, and tumoricidal effects on hosts. Albendazole and mebendazole are most frequently prescribed for treatment of intestinal nematode infections (ascariasis, hookworm infections, trichuriasis, strongyloidiasis, and enterobiasis) and can also be used for intestinal tapeworm infections (taeniases and hymenolepiasis). However, these drugs also exhibit considerable therapeutic effects against tissue nematode/cestode infections (visceral, ocular, neural, and cutaneous larva migrans, anisakiasis, trichinosis, hepatic and intestinal capillariasis, angiostrongyliasis, gnathostomiasis, gongylonemiasis, thelaziasis, dracunculiasis, cerebral and subcutaneous cysticercosis, and echinococcosis). Albendazole is also used for treatment of filarial infections (lymphatic filariasis, onchocerciasis, loiasis, mansonellosis, and dirofilariasis) alone or in combination with other drugs, such as ivermectin or diethylcarbamazine. Albendazole was tried even for treatment of trematode (fascioliasis, clonorchiasis, opisthorchiasis, and intestinal fluke infections) and protozoan infections (giardiasis, vaginal trichomoniasis, cryptosporidiosis, and microsporidiosis). These drugs are generally safe with few side effects; however, when they are used for prolonged time (>14-28 days) or even only 1 time, liver toxicity and other side reactions may occur. In hookworms, Trichuris trichiura, possibly Ascaris lumbricoides, Wuchereria bancrofti, and Giardia sp., there are emerging issues of drug resistance. It is of particular note that albendazole and mebendazole have been repositioned as promising anti-cancer drugs. These drugs have been shown to be active in vitro and in vivo (animals) against liver, lung, ovary, prostate, colorectal, breast, head and neck cancers, and melanoma. Two clinical reports for albendazole and 2 case reports for mebendazole have revealed promising effects of these drugs in human patients having variable types of cancers. However, because of the toxicity of albendazole, for example, neutropenia due to myelosuppression, if high doses are used for a prolonged time, mebendazole is currently more popularly used than albendazole in anti-cancer clinical trials.

  • In this study, we evaluated the anti-cancer activity and potential molecular mechanism of 70% ethanol extracts of branches from Taxillus yadoriki parasitic to Neolitsea sericea (TN-NS-B) against human lung cancer cells, A549. TY-NS-B dose-dependently suppressed the growth of A549 cells. TY-NS-B decreased ${\beta}$-catenin protein level, but not mRNA level in A549 cells. The downregulation of ${\beta}$-catenin protein level by TY-NS-B was attenuated in the presence of MG132. Although TY-NS-B phosphorylated ${\beta}$-catenin protein, the inhibition of $GSK3{\beta}$ by LiCl did not blocked the reduction of ${\beta}$-catenin by TY-NS-B. In addition, TY-NS-B decreased ${\beta}$-catenin protein in A549 cells transfected with Flag-tagged wild type ${\beta}$-catenin or Flag-tagged S33/S37/T41 mutant ${\beta}$-catenin construct. Our results suggested that TN-NS-B may downregulate ${\beta}$-catenin protein level independent on GSK3${\beta}$-induced ${\beta}$-catenin phosphorylation. Based on these findings, TY-NS-B may be a potential candidate for the development of chemopreventive or therapeutic agents for human lung cancer.

  • Toxocara (T.) canis and Trichuris (T.) vulpis are very important canine parasitic nematodes. T. canis parasitize in small intestine and T. vulpis parasitize in large intestine. In order to control of these nematodes, ivermectin and pyrantel pamoate compound was applied to the dogs infected with these parasites naturally and artificially. This drug was composed of $68.0{\mu}g$ of ivermectin and 57.0 mg of pyrantel pamoate for small animal, $136.0{\mu}g$ of ivermectin and 114.0 mg of pyrantel pamoate for middle animal, and $272.0{\mu}g$ of ivermectin and 227.0 mg of pyrantel pamoate for large animal. Ivermectin in this drug is activity to nematodes and ectoparisites. Pyrantel pamoate in this drug is also activity to nematodes. In this experiment, this drug had a good efficacy against T. canis and T. vulpis in the infected dogs.

  • The chemical components and biological activity of Camellia mistletoe, Korthalsella japonica (Loranthaceae) are relatively unknown compared to other mistletoe species. Therefore, we investigated the phytochemical properties and biological activity of this parasitic plant to provide essential preliminary scientific evidence to support and encourage its further pharmaceutical research and development. The major plant components were chromatographically isolated using high-performance liquid chromatography and their structures were elucidated using tandem mass spectrometry and nuclear magnetic resonance anlysis. Furthermore, the anti-inflammatory activity of the 70% ethanol extract of K. japonica (KJ) and its isolated components was evaluated using a nitric oxide (NO) assay and western blot analysis for inducible NO synthase (iNOS) and cyclooxygenase (COX)-2. Three flavone di-C-glycosides, lucenin-2, vicenin-2, and stellarin-2 were identified as major components of KJ, for the first time. KJ significantly inhibited NO production and reduced iNOS and COX-2 expression in lipopolysaccharide-stimulated RAW 264.7 cells at $100{\mu}g/mL$ while similar activity were observed with isolated flavone C-glycosides. In conclusion, KJ has a simple secondary metabolite profiles including flavone di-C-glycosides as major components and has a strong potential for further research and development as a source of therapeutic anti-inflammatory agents.

  • In an attempt to find a feed additive showing an anti-scuticociliate effect, extracts from Citrus unshiu Peel were tested against virulent scuticociliate infection. The most effective anti-scuticociliate killing activity in vitro was observed in the extract squeezed from homogenizing water-soaked dried tangerine peel (DTP). In addition, we have investigated the effect of DTP as a feed additive on growth rate and anti-parasitic activity of olivaceus flounder. DTP extract added diets (0.1, 0.5, 1, and 5%/feed weight) were fed to flounder for 7 days for checking a growth rate and 14 days for a challenging test. As a result, the feed conversion rate was significantly improved only in 1% DPT extract group compared to the control and 0.5% DTP extract fed group showed 100% of survival rate in the challenge test, all of which indicating that DTP extract would be a potential feed additive against scuticociliatosis.

  • Galla Rhois is a nest of parasitic bug, has been traditionally used for the treatment of the therapy of diarrhea, peptic ulcer, hemauria, etc., that showed various anti-inflammatory activity, and other biological properties. We studied the effect of Galla Rhois ethanol extract. we investigated whether compounds isolated from the ethanol extract of Galla Rhois, could modulate iNOS and COX-2 expression in RAW 264.7 macrophages stimulated with lipopolysaccharide (LPS). We found compounds that suppressed LPS-induced iNOS and COX-2 expression. Suppression of the expression of iNOS and COX-2 was in parallel with the comparable inhibition of the production of nitric oxide (NO) and prostaglandin E2 (PGE2). Our results suggest that compounds can inhibit NO and PGE2 productions through suppression of LPS-induced iNOS and COX-2 expression. Because COX-2- or iNOS-dependent mechanisms are involved in inflammation and tumor progression, our findings provide a new uncovering mechanism responsible for anti-inflammatory and antitumor effects of Galla Rhois.
