Compound 8a, belonging to the benzimidazole group (Figure 4) with an amide bond, showed positive pharmacokinetic properties. Based on research, it was found that this drug has anthelmintic properties and inhibits the risk of liver damage by Schistosoma eggs [52]. A parasite is a tiny microorganism (microscopic organism). In the case of 3af compounds containing the following substituents: nitro, methoxy and bromo in the para position, the IC50 values were: 18.3, 14.2 and 13.9 M, respectively, which proves their high antiparasitic effectiveness. Antiparasitic drugs work by: Depending on the type of infection and the parasite that caused it, you may take antiparasitic medications: In general, children and adults who have an infection that results from a parasite need antiparasitic medication. Parasitic infectionsare more commonin tropical areas, but they can also occur in subtropical and temperate regions. DRUG INTERACTIONS. When analyzing new structures, compounds with very different structures show promising antiparasitic activity, but it seems that the most promising are thiosemicarbazide derivatives, characterized by high activity in both Toxoplasma gondii and nematodes of the genus Rhabditis sp. Camargo et al. The presence of a substituent, such as nitro or methoxy or bromo groups in the para position with respect to the aryl ring in the fifth position of the pyrazole, determined the antiparasitic effect. Parasites are microorganisms that live on or inside another organism (the host) and benefit at the expense of their host. Thanks to sugar groups, these compounds are perfectly absorbed by parasites. An alternative to synthetic compounds may be natural compounds obtained from plants. The drug was well tolerated by the participants in the study, regardless of their gender. It is also used to treat typical scabies when topical permethrin is not effective [34,35]. Some antiparasitic medications can cause serious health problems if you take more than you should or you take them for too long. Most clinical trials are focused on malaria, without other parasitic diseases, which are also widespread in highly developed countries. Al Nasr I.S., Jentzsch J., Shaikh A., Shuveksh P.S., Koko W.S., Khan T.A., Ahmed K., Schobert R., Ersfeld K., Biersack B. For example, miltefosine, which originally was used as an anticancer drug in animals (1987), was approved in India in 2002 as an anti-leishmaniasis drug. It exhibits a different mechanism of action than available drugs, therefore it is an interesting direction of research in the treatment of onchocerciasis. Chan J.D., Day T.A., Marchant J.S.

We report known drugs used in other disease entities with proven antiparasitic activity and research on new chemical structures that may be potential drugs in parasitic diseases. Metacaspases are cysteine proteases that have the catalytic Cys-His dyad and are found in fungi, protozoa and plants. These include abnormal heart rate, vision changes, hallucinations and psychosis. Oxfendazole treatment has a macrofilaricidal efficacy against the filarial nematode. It should be emphasized that the effectiveness of artemether has not been confirmed in human clinical trials. Many research groups are looking for effective antiparasitic drugs with low side effects. The highest in vitro anti-Toxoplasma activity was found in the meta-iodophenyl derivative (Figure 20). Among the newly obtained compounds, the most potent compounds are: (R)-5-((S)-1-aminoethyl)-3-(3-fluoro-4-morpholinophenyl)oxazolidin-2-one, (S)-5-((S)-1-aminoethyl)-3-(3-fluoro-4-morpholinophenyl)oxazolidin-2-one (6 and 7), ((R)-((S)-3-(3-fluoro-4-morpholinophenyl)-2-oxooxazolidin-5-yl)ethyl)acetamide, and ((S)-((S)-3-(3-fluoro-4-morpholinophenyl)-2-oxooxazolidin-5-yl)ethyl)acetamide (8 and 9). Similarly, as in the case of the previous compounds, the new derivatives were characterized by a much lower activity (IC50 values 968 times lower) than sulfadiazine used as a reference drug [83]. Promethazine is a phenothiazine derivative, an H1 receptor antagonist, belonging to the group of antihistamines. In the first stage, thiosemicarbazones were obtained by condensing thiosemicarbazide derivatives with hydroxybenzaldehydes. 9500 Euclid Avenue, Cleveland, Ohio 44195 |, Important Updates + Notice of Vendor Data Event, (https://www.ncbi.nlm.nih.gov/books/NBK544251/), (https://www.merckmanuals.com/home/infections/parasitic-infections-an-overview/overview-of-parasitic-infections), (https://www.cdc.gov/parasites/about.html).
