As resistências aos antibióticos tem sido alvo de grande preocupação. A necessidade da descoberta de novos antibióticos é cada vez maior. Cada vez mais os produtos naturais são vistos como alternativas viáveis à resolução deste problema. O género Plectranthus, pertencente à família Laminaceae, possui propriedades antimicrobianas amplamente descritas na literatura. A sua ação bactericida deve-se a metabolitos, nomeadamente a diterpenos. A nanotecnologia é um campo bastante promissor. As nanopartículas metálicas, em especial as nanopartículas de prata, possuem um grande rácio superficie/volume, que lhes confere a capacidade de interagir com as membranas bacterianas. A funcionalização das nanopartículas de prata com a 7α-acetoxi-6Bhidroxiroileanona demonstra viabilidade para o desenvolvimento de uma formulação com propriedades antibacterianas.
Antibiotic resistance has been a major concern. The need for the discovery of new antibiotics is increasing. Natural products are seen as viable alternatives to solving this problem. The genus Plectranthus, belonging to the family Laminaceae, has antimicrobial properties widely described in the literature. His bactericidal action is due to metabolites, namely diterpenes. Nanotechnology is a very promising field. Metal nanoparticles, especially silver nanoparticles, have a large surface to volume ratio, which gives them the ability to interact with bacterial membranes. Functionalization of silver nanoparticles with 7α-acetoxy-6B-hydroxyroyleanone demonstrates the feasibility of developing a formulation with antibacterial properties.
