Tigliane Diterpenoids with Larvicidal, Antifungal, and α‑Glucosidase Inhibitory Activities from Croton damayeshu

Thirty-five tigliane diterpenoids and two ent-kaurane diterpenoids were isolated from the leaves of Croton damayeshu, and, among them, compounds 1–10 were characterized as new tigliane diterpenoids. The structures of compounds 1–10 were determined by analysis of their HRESIMS, NMR, and ECD data and...

Zusammenfassung:Thirty-five tigliane diterpenoids and two ent-kaurane diterpenoids were isolated from the leaves of Croton damayeshu, and, among them, compounds 1–10 were characterized as new tigliane diterpenoids. The structures of compounds 1–10 were determined by analysis of their HRESIMS, NMR, and ECD data and by chemical methods. The isolates were assayed for their larvicidal, antifungal, and α-glucosidase inhibitory activities, and compounds 8–10 were found to possess larvicidal activities against Plutella xylostella with LC50 values of 0.19, 0.16, and 0.26 μM, respectively, comparable to the LC50 of 0.14 μM for the positive control, flubendiamide.
