Abstract

According to the World Health Organization (WHO), leishmaniasis is a neglected disease that afflicts people in underdeveloped countries, and disfigures, stigmatizes and kills. Therefore, through a Special Research and Training Programme (TDR) the WHO aimed to eradicate this disease, which is currently treated with expensive and toxic drugs. Researchers have characterized and purified proteins of microorganisms that are pathogenic to humans, a strategy in the search for molecules that can act as biological targets. The enzyme Nucleoside Diphosphate Kinase B (NDKb) has a key role in maintaining the amount of intracellular NTPs and dNTPs it is secreted by Leishmania major and is determines the invasive / evasive process during successful infection of macrophages. Considering that the enzyme is a potential biological target, it is necessary to develop and/or upgrade techniques, to conduct skillful studies on this biomolecule. Biochromatography has successfully been used in this sense and the association of IMERs with chromatographic systems is a highly efficient multidimensional method that is potentially applicable in the screening of selective inhibitors. Hence, in this project we propose the immobilization of enzymes NDKb of Leishmania major and its mutant K30A onto silica capillary, which will later be engaged in a multidimensional method that will be developed and validated.
