Resumo

A leishmaniose é uma doença infecciosa que afeta animais e humanos, causada por parasitas flagelados pertencentes ao gênero Leishmania, podendo apresentar-se em diferentes formas clínicas, dependendo da cepa infectante e da reação imune do hospedeiro. Estima-se que a doença atinja cerca de 700.000 a 1 milhão de pessoas, causando a morte de 20 a 30.000 indivíduos anualmente. Assim, o presente estudo tem como objetivo realizar uma simulação de acoplamento molecular do complexo de rutênio com epiisopiloturina e óxido nítrico contra a proteína Nucleosídeo difosfato cinase de Leishmania amazonensis. A molécula em 3D NDK foi extraída do banco de dados de proteínas e ácidos nucleicos PDB. A estrutura molecular 3D do complexo Epiruno2 foi projetada usando o software gaussview 5.0. O alvo NDK e o complexo Epiruno2 foram preparados para simulações de ancoragem, onde o NDK foi considerado rígido e o Epiruno2 foi considerado flexível. O complexo Epiruno2 apresentou boa taxa de afinidade molecular com a proteína alvo, tornando-o atrativo para ensaios experimentais em laboratórios para a proteína NDK da Leishmania e NDKs de outros patógenos, no entanto, o fármaco miltefosina apresentou baixa afinidade molecular para o mesmo alvo, corroborando com estudos apresentados na literatura sobre a eficácia reduzida dos medicamentos atuais contra a leishmaniose.
