Summary: Abstract: Cutaneous leishmaniasis (CL) is considered a public health problem. Current treatments have disadvantages because they are invasive and have serious side effects, and thus there is a need for research into new, more effective pharmacological alternatives. Plants are promising sources of bioactive substances, and new analogues can be obtained through chemical reactions. The present study aimed to evaluate the antileishmanial effects of the analog dillapiole n-butyl ether (DBE) extracted from Piper aduncum leaves. The cytotoxic potential of DBE was evaluated at concentrations of 15.62 to 500 ?M in peritoneal macrophages for 48 h, and in RAW 264.7 macrophages for 72 h using a dose-response method. Resumo: A leishmaniose cutânea (LC) é considerada um problema de saúde pública. Os tratamentos atuais apresentam desvantagens por serem invasivos e possuem efeitos colaterais graves, levando a pesquisa de novas alternativas farmacológicas mais eficazes. As plantas são fontes promissoras de bioativos, e por meio de reações químicas pode-se obter novos análogos. O presente estudo objetivou avaliar os efeitos antileishmania do análogo éter n-butil do dilapiol (EBD) extraído das folhas de Piper aduncum. Foi avaliado o potencial citotóxico do EBD nas concentrações de 15,62 a 500 ?M em macrófagos peritoneais por 48 h, e em macrófagos RAW 264.7 por 72 h utilizando o método dose-resposta.
