“…Alkenylphenols with different reported biological properties, such as antibacterial, anti-parasitic, anti-inflammatory and cytotoxic activities, are widely found in the Piper genus [17,19,20,21,45]. Quinols are 4-hydroxycyclohexa-2,5-dien-1-ones which rarely occur as derivatives of some natural products [46,47,48]. An important feature of quinols substituted in the 4-position with aryl groups, is that they represent a class of potent anti-tumour molecules with activities against colon, renal, and breast cancer cells [49,50,51].…”

“…Os estudos realizados com espécies do gênero Piper tem resultado no isolamento de substâncias de diversas classes de metabólitos secundários, muitas dessas substâncias com destacada atividade biológica. Entre essas substâncias, podem ser citadas amidas (da Silva et al, 2002;Ghosal et al, 2012;Marques et al, 2007;Navickiene et al, 2000), ácidos benzoicos prenilados (Baldoqui et al, 1999;Freitas et al, 2009;Lago et al, 2009;Lago et al, 2004;Puhl et al, 2011), neolignanas (Benevides et al, 1999;Chauret et al, 1996;Jiang et al, 2003), hidroquinonas preniladas (Danelutte et al, 2003;Yamaguchi et al, 2006), flavonoides (de Queiroz et al, 2014;Freitas et al, 2014) e lignanas (Cabral et al, 2009;Martins et al, 2003;Martins et al, 2000). Estudos recentes tem mostrado que os metabólitos secundários encontrados em espécies de Piper podem ser importantes nas relações ecológicas dessas plantas com insetos (Bernard et al, 1995;, 2012Ramos et al, 2012a;Ramos et al, 2012b).…”
