Novos métodos cromatográficos para análise e separação de novos produtos naturais antimicrobianos

Abstract

Cerca de metade dos fármacos usados actualmente na clínica quotidiana derivam de um produto natural. Os produtos naturais estão a ganhar uma maior importância na investigação de novos fármacos antimicrobianos devido ao aumento das resistências a este tipo de fármacos, derivado ao mau uso, tanto no humano como no veterinário. De modo a combater este problema de saúde pública mundial, a pesquisa de novas moléculas com actividade antimicrobiana é actualmente um tópico de pesquisa muito relevante. Por forma a diminuir o tempo e dinheiro gasto na pesquisa destas moléculas recorre-se cada vez mais a técnicas cromatográficas hifenizadas, como é exemplo a cromatografia liquida-espectrometria de massa. Estas técnicas associam uma ou mais técnicas de separação analíticas, como a cromatografia gasosa, com um ou mais detectores dos compostos a analisar (analitos) separados, como por exemplo o espectrómetro de massa. No presente trabalho apresentam-se algumas das técnicas cromatográficas mais recentes utilizadas na pesquisa de novas moléculas com actividade farmacológica antimicrobiana.

Currently, about half the pharmaceuticals used in everyday clinics derive from a natural product. Natural products are gaining relevance in the research of novel antimicrobial drugs due to the increase in the microbial resistance to these type of drugs, especially as a consequence of their incorrect use, human and animal. To overcome this world public health problem, research on new antimicrobial molecules is currently a very relevant research topic. As a way to reduce the amount of time and money spent in the research of these molecules, the use of hyphenated chromatographic techniques, such as liquid chromatography-mass spectrometry, is increasing. These techniques combine one or more analytical separation techniques, such as gas chromatography, with one or more compound detectors, such as the mass spectrometer. In this work we present some of the new chromatographic techniques used in the research of new molecules with antimicrobial pharmacological activity.
