Here, we synthesized and evaluated the schistosomicidal, biochemical and cytotoxic activities of EF24, a synthetic curcumin analog, against different isolates of Schistosoma mansoni. EF24 elicited marked phenotypic alterations at 10 µM against schistosomula and 42-day-old adult worms of the Naval Medical Research Institute (NMRI) isolate. EF24 had 50% effective concentration (EC50) values of <10 µM against the Luis Evangelista (LE), Sergipe (SE), Belo Horizonte (BH) and Belo Horizonte less sensitive to PZQ (BH < PZQ) isolates of adult S. mansoni; however, the respective sensitivities of these isolates differed. Changes in the parasite included, vacuolization of the tegument and focal lysis of the interstitial tissue and muscle layers. Against 28-day-old juvenile worms (LE isolate), EF24 was about three times more potent than PZQ. After 6 h at 12.5 µM, EF24 increased reactive oxygen species (ROS) and the activity of the antioxidant enzyme, glutathione-S-transferase (GST), by 32 and 19% in female and male adult worms, respectively. By contrast, after 6 h at 12.5 µM glutathione reductase (GR) activity decreased by 43 and 30%, and glutathione peroxidase (GPx) activity decreased by 67 and 44% in females and males, respectively. EF24 was less cytotoxic to mammalian host cells than to S. mansoni, with selectivity indexes (SIs) of 1.8-3.4 and 2.7-7.5 for juvenile and adult worms, respectively. Given the current evidence for the in vitro schistosomicidal effect of EF24, the structure-activity relationship of additional analogs to identify new candidates for schistosomiasis treatment is warrantedCONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPAbertoUNIVERSIDADE ESTADUAL DE CAMPINASBadoco, Fernanda RafachoCabral, Fernanda Janku, 1973-Allegretti, Silmara Marques, 1963-Mendes, Tiago Manuel Fernandes, 1989-2022info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://hdl.handle.net/20.500.12733/27839BADOCO, Fernanda Rafacho et al.
