Bioactive compounds from the insect Aspongopus chinensis

Recent studies focusing on unveiling the biological agents of Aspongopus chinensis have led to the identification of four new norepinephrine derivatives (1–4), three new sesquiterpenoids (5–7), and one new lactam (8). In addition, twenty-three known compounds have been identified, most of which were isolated from this insect for the first time. Selected members of insect-derived substances were evaluated for their biological activities against...
