Prenylated C6–C3 derivatives from the stems and branches of Illicium ternstroemioides A. C. Smith with antiviral activity

seco-Sesquiterpenes and acorane-type sesquiterpenes with antiviral activity from the twigs and leaves of Illicium henryi Diels

“…The genus Illicium has been regarded as a rich source of sesquiterpenes [1][2][3][4][5][6][7][8][9], especially seco-prezizaanetype sesquiterpenes and prenylated C6-C3 compound derivatives [10][11][12][13][14][15][16], which have distinct structural features and various carbon skeletons. Some of the sesquiterpenes have exhibited intriguing antiviral, neuroprotective, and neurotrophic activities [7,[17][18][19][20][21], while many prenylated C6-C3 compounds were found to exhibit increased choline acetyltransferase, cytotoxic and antiviral activities [12][13][14]22].…”
