ent-Kaurane Diterpenoids from Annona glabra

Abstract: Three new kaurane diterpenoids, annoglabasin C (16alpha-acetoxy-ent-kauran-19-oic acid-17-methyl ester) (1), annoglabasin D (16alpha-acetoxy-ent-kauran-19-al-17-methyl ester) (2), and annoglabasin E (16alpha-hydro-19-ol-ent-kauran-17-oic acid) (3), and a new norkaurane diterpenoid, annoglabasin F (16alpha-acetoxy-19-nor-ent-kauran-4alpha-ol-17-methyl ester) (4), along with 13 known kaurane derivatives were isolated from the stems of Annona glabra. 16alpha-Methoxy-ent-kauran-19-oic acid (5) and 16alpha-hydro-en… Show more

“…Estudos químicos sobre a Annona glabra L. confi rmaram a presença de grupos de substâncias com possível potencial alelopático, como monoterpenóides (Grayson 2000) e diterpenóides, isolados de diferentes partes da planta (Chang et al 1998;Chen et al 2000;Yang et al 2003;Zhang et al 2004). Chang et al (2000) e Hsieh et al (2004) isolaram alcalóides, esteróides e outros diterpenóides.…”

“…The whole plant is used in traditional medicine as an anticancer drug (Cochrane et al, 2008). Phytochemical investigation of this plant led to the isolation of acetogenins (Liu et al, 1999), ent-kauranes (Chen et al, 2000(Chen et al, , 2004, peptides (Li et al, 1999), and alkaloids (Likhitwitayawuid et al, 1993;Tsai & Lee, 2010). In addition, they exhibited anticancer (Chen et al, 2004), anti-HIV-reserve (Chang et al, 1998), and antimalaria activities (Likhitwitayawuid et al, 1993).…”
