Abstract
Nitazoxanide (NTZ) is a broad-spectrum drug used in intestinal infections, but still poorly explored in the treatment of parasitic tissular infections. This study aimed to evaluate the in vitro responses of the energetic metabolism of T. crassiceps cysticerci induced by NTZ. The organic acids of the tricarboxylic acid cycle, products derived from fatty acids oxidation and protein catabolism were analyzed. These acids were quantified after 24 h of in vitro exposure to different NTZ concentrations. A positive control group was performed with albendazole sulfoxide (ABZSO). The significant alterations in citrate, fumarate and malate concentrations showed the NTZ influence in the tricarboxylic acid (TCA) cycle. The non-detection of acetate confirmed that the main mode of action of NTZ is effective against T. crassiceps cysticerci. The statistical differences in fumarate, urea and beta-hydroxybutyrate concentrations showed the NTZ effect on protein catabolism and fatty acid oxidation. Therefore, the main energetic pathways such as the TCA cycle, protein catabolism and fatty acids oxidation were altered after in vitro NTZ exposure. In conclusion, NTZ induced a significant metabolic stress in the parasite indicating that it may be used as an alternative therapeutic choice for cysticercosis treatment. The use of metabolic approaches to establish comparisons between anti parasitic drugs mode of actions is proposed.

Abstract
Neurocysticercosis is the most frequent helminthiasis of the central nervous system and is caused by the presence of Taenia solium cysticerci. Nitazoxanide (NTZ) is an antifolate containing the pyrrolopyrimidine-based nucleus that exerts its antiprotozoal activity due to interference with the pyruvate:ferredoxin oxidoreductase (PFOR) enzyme which is essential to anaerobic energy metabolism. The aim of this work was to determine the effect of NTZ on the energetic metabolism of Taenia crassiceps cysticerci intracranially inoculated BALB /c mice. The infected animals were treated with a single oral dose of NTZ 30 days after the inoculation. Analysis of the organic acids was performed through high performance liquid chromatography. Glucose was detected only in the treated groups, alongside with a significant decrease in lactate, pyruvate and oxaloacetate concentrations which indicate an increase in gluconeogenesis. The non-detection of alpha-ketoglutarate indicated the use of the fumarate reductase pathway in all groups. It was possible to confirm the drugs mode of action due to the non-detection of acetate in the treated groups. There was an increase in the fatty acids oxidation. Therefore it was possible to observe that NTZ induces gluconeogenesis as well as the increase of alternative energetic pathways such as fatty acids oxidation in T. crassiceps cysticerci.

Abstract
The emergence of resistance to albendazole has encouraged the search for effective alternatives for cysticercosis and other parasitosis treatment. RCB15 is a benzimidazole derivative that may be used against such diseases. The aim of this study was to determine the in vitro effect of RCB15 on the alternative energetic pathways of Taenia crassiceps cysticerci. The cysticerci were in vitro exposed to albendazole sulphoxide (ABZSO) or RCB15 at different concentrations during 24h. The cysticerci extract and the culture medium were analyzed through spectrophotometry and high performance liquid chromatography as to detect glucose, urea, creatinine and organic acids of the energetic metabolism. The drugs did not influence the protein catabolism. Fatty acids oxidation was enhanced through significantly higher acetate concentrations in the groups treated with RCB15 and ABZSO. Beta-hydroxybutyrate concentrations were decreased which indicates the use of fatty acids towards acetyl-CoA synthesis. There was a decrease in glucose uptake and pyruvate concentrations. The absence of lactate indicates the use of pyruvate in gluconeogenesis. Therefore it is possible to conclude that RCB15 enhanced the alternative energetic pathways of cysticerci in vitro exposed to different concentration, with emphasis on the fatty acids catabolism.
