TY - CHAP. T1 - Antiparasitic Agents. AU - Leder, Karin. AU - McGuinness, Sarah L. AU - Weller, Peter F. PY - 2019. Y1 - 2019. N2 - A number of effective antiprotozoal and anthelmintic drugs are currently available. Antiparasitic agents are important both for therapy of infected individual patients and for control of parasitic infections at the community level. Large-scale chemotherapy is reducing transmission, morbidity, and mortality of certain infections, including lymphatic filariasis, onchocerciasis, schistosomiasis, and infections with intestinal nematodes. However, the lack of financial incentives to develop new agents is a major limitation to the future of antiparasitic chemotherapy. Emerging resistance among parasites, lack of effective antiparasitic vaccines, and the enormous burden of disease worldwide also pose challenges to the effective management of parasitic infections. This chapter focuses on the mechanisms of action, pharmacology, clinical utility, and adverse effects of common ...

The U.S. small ruminant industry needs new antiparasitic drugs, and the sustainable use of these drugs will help maintain their effectiveness for as long as possible.
Background: Parasitic diseases including malaria, leishmaniasis and schistosomiasis take a terrible toll of human life, health and productivity, especially in tropical and subtropical regions, and are also highly significant in animal health worldwide. Antiparasitic drugs are the mainstays of control of most of these diseases, but in many cases current therapies are inadequate and in some the situation is deteriorating because of drug resistance. Microtubules, as essential components of almost all eukaryotic cells, are proven drug targets in many helminth diseases and show promise as targets for the development of new antiprotozoal drugs. Objective: This article reviews the chemistry of the microtubule inhibitors in current use and under investigation as antiparasitic agents, their activities against the major parasites and their mechanisms of action. New directions in both inhibitor chemistry and biological evaluation are discussed. Conclusions: The most promising immediate avenues for discovery and
Six medical students inhabiting a centuries-old, rat-infested house in Lübeck, in northern Germany, were suffering from itching papules and seropapules. Prior to these patients visit to our institute, their conditions had been diagnosed as pediculosis, scabies, or pulicosis and treated unsuccessfully with the antiparasitic agent lindane (0.3%). The final diagnosis, tropical rat mite dermatitis, was based on the identification of the arthropod Ornithonyssus bacoti, which has an unsegmented body with eight legs. No treatment was recommended, and the dermatitis disappeared within 2 weeks. Measures taken to prevent reinfestation included extermination of the rats and treatment of the rooms of the house with the acaricide benzyl benzoate. Because the mite O. bacoti spends a relatively short time on a host and penetrates the skin for feeding only, the application of an antiparasitic agent is not necessary. If indicated, treatment should be symptomatic.. ...

Press Release issued Aug 2, 2017: The Animal Parasiticides Market is growing tremendously due to the increasing trend of pet adoption amongst people in developed as well as developing economies. However, the cost associated with animal parasiticides products, heavy expenditure on R & D for new product development and stringent regulatory policies related to the approval of animal parasiticides are factors that are adversely affecting the growth of the market.
Nitazoxanide is a broad-spectrum antiparasitic and broad-spectrum antiviral drug that is used in medicine for the treatment of various helminthic, protozoal, and viral infections. It is indicated for the treatment of infection by Cryptosporidium parvum and Giardia lamblia in immunocompetent individuals and has been repurposed for the treatment of influenza. Nitazoxanide has also been shown to have in vitro antiparasitic activity and clinical treatment efficacy for infections caused by other protozoa and helminths; emerging evidence suggests that it possesses efficacy in treating a number of viral infections as well. Chemically, nitazoxanide is the prototype member of the thiazolides, a class of drugs which are synthetic nitrothiazolyl-salicylamide derivatives with antiparasitic and antiviral activity. Tizoxanide, an active metabolite of nitazoxanide in humans, is also an antiparasitic drug of the thiazolide class. Nitazoxanide is an effective first-line treatment for infection by Blastocystis ...

Parasitic infections afflict more than half of the worlds population and impose a substantial health burden, particularly in underdeveloped nations, where they are most prevalent. The reach of some parasitic diseases, including malaria, has expanded over the past few decades as a result of factors such as deforestation, population shifts, global warming, and other climatic events. Despite major efforts at vaccine development and vector control, chemotherapy remains the single most effective means of controlling parasitic infections. Efforts to combat the spread of some diseases are hindered by the development and spread of drug resistance, the limited introduction of new antiparasitic agents, and the proliferation of counterfeit medications. However, there are good reasons to be optimistic. Ambitious global initiatives aimed at controlling or eliminating threats such as AIDS, tuberculosis, and malaria have demonstrated some early successes. Recognition of the substantial burden imposed by the ...

Parasitic infections remain one of the most pressing global health concerns of our day, affecting billions of people and producing unsustainable economic burdens. The rise of drug-resistant parasites has created an urgent need to study their biology in hopes of uncovering new potential drug targets. It has been established that disrupting gene expression by interfering with lysine acetylation is detrimental to survival of apicomplexan (Toxoplasma gondii and Plasmodium spp.) and kinetoplastid (Leishmania spp. and Trypanosoma spp.) parasites. As "readers" of lysine acetylation, bromodomain proteins have emerged as key gene expression regulators and a promising new class of drug target. Here we review recent studies that demonstrate the essential roles played by bromodomain-containing proteins in parasite viability, invasion, and stage switching and present work showing the efficacy of bromodomain inhibitors as novel antiparasitic agents. In addition, we performed a phylogenetic analysis of ...

There are disclosed certain new compounds related to C-076 compounds which have been produced by a mutant of the culture that produced the original C-076 compounds and isolated from the fermentation broth thereof. The compounds retain the C-076 16-membered cyclic backbone, however, the groups attached thereto are considerably modified from the original C-076 compounds. The new compounds have been found to retain the biological activity of the parent C-076 compounds. The compounds are thus potent antiparasitic agents and compositions and methods for such uses are also disclosed.
Alcohol use disorders (AUDs) ranks third in the list of preventable causes of morbidity and mortality in United States having a major national impact affecting over 18 million people and causing over 100,000 deaths annually. The prevalence of AUDs, in combination with limited clinical efficacy of currently approved FDA drugs in the treatment of this disorder signifies the importance for development of novel therapeutic agents. Alcohol is known to modulate a multitude of receptors in the brain to induce its cellular and behavioral effects. Recent electrophysiological findings from our laboratory, coupled with genomic studies, have suggested that the ionotropic receptor, P2X4 receptor (P2X4R) is a critical target that is modulated by ethanol. P2X4R activity has been demonstrated to be inhibited by ethanol at intoxicating and anesthetic concentrations. Recent evidence from our laboratory using electrophysiological strategies has shown that the FDA approved antiparasitic agent, ivermectin (IVM) ...

Formalin is a liquid formulation of 37% formaldehyde gas dissolved in water. Two brands of formalin, Formalin-F (Natchez Animal Supply, Natchez, Miss.) and Paracide-F (Argent Chemical Laboratories, Redmond, Wash.), have been approved by FDA as parasiticides for use on fish. Formalin is effective against many external parasites, including protozoans and monogenetic trematodes. It is not generally considered the best treatment for external fungal or bacterial infections. Formalin can be delivered in a short-term bath at a concentration of 250 mg/l - or 150 mg/l if water temperature is greater than 70°F (21°C) - for no more than 60 minutes. It can be delivered as an indefinite bath at a concentration of 15 to 25 mg/l. Formalin is an excellent parasiticide for use in tanks and aquaria, but its use in ponds is discouraged because it chemically removes oxygen from the water and can contribute to catastrophic oxygen depletion under pond conditions. This is avoided in tanks and aquaria by always ...
Contributing to the complicated nature of pet parasite control, regulation and availability of these products is not uniform. Some products are considered insecticides and, in the United States, are regulated by the Environmental Protection Agency, while others count as medications and fall under the jurisdiction of the U.S. Food and Drug Administration. Some flea-and-tick control methods are available to pet owners over the counter from pet and big-box stores. Others are available only from veterinary clinics or from pharmacies presented with a prescription from a veterinarian who has examined the pet. ...

Dr Butters works in the Glycobiology Institute which is headed by Professor Raymond Dwek. His expertise in glycoprotein biology led to him being contacted by Dr Rossignol.. Dr Rossignol approached our group to see if we could help him find a mechanism of action for thiazolides. If we understand the mechanism better, then well be able to improve drug design, explains Dr Butters.. His group works with small molecules that interfere with the cellular processes responsible for glycoprotein production. He is trying to develop these into drugs against the hepatitis C virus which also uses a viral envelope glycoprotein.. If more can be uncovered about how thiazolides work, this may also open up the possibility of using them in combination with compounds Dr Butters own lab is developing.. We have a known mechanism of action for our compounds, and our initial experiments suggest that the drug works in a slightly different way. Both interfere with glycoprotein maturation of viral envelope proteins, ...
