Biological Activities
Bertholletia excelsa is a remarkable Amazonian species that demonstrates significant therapeutic potential through its diverse bioactive properties. Research highlights its effective antimicrobial activity, specifically showing success against pathogens such as Escherichia coli, Klebsiella pneumoniae, Aspergillus sp., and Candida sp. Beyond fighting bacteria and fungi, this plant also possesses potent antiplasmodial properties essential for combating malaria. In vitro studies have confirmed its efficacy against chloroquine-resistant Plasmodium falciparum parasites, validating the traditional knowledge of local quilombola communities. These combined medicinal capabilities underscore the vital importance of conserving such native species for future drug development.
Compounds
Conditions
Bertholletia excelsa demonstrates significant antimicrobial activity against various pathogens, specifically targeting Aspergillus sp., Candida sp., and Escherichia coli. Beyond its antimicrobial properties, the plant shows promising anti-inflammatory potential through the inhibition of the COX-2 enzyme. In vivo studies using zebrafish models further confirm its efficacy by reducing carrageenan-induced abdominal oedema. These diverse biological interactions highlight the plant's multifaceted medicinal value in treating both microbial infections and inflammatory responses.
Preparations
Bertholletia excelsa is prepared as oil to serve as a foundational material for synthesizing bioactive fatty amides. This specific oil, referred to as AGBe, is utilized to create chemical structures that mimic the effects of spilantol. Researchers use the oil to develop fatty ethanolamide triglycerides that exhibit significant anti-inflammatory properties. The preparation of this oil allows for the successful reduction of abdominal oedema in zebrafish models. Ultimately, the oil functions as a safe and effective source for producing compounds that inhibit COX-2 and PLA2 enzymes.
