Abstract Juvenoids 16–30, 32, 36, 38–41, 44–46, and 49–56 containing carbamate, carbonate, and urea moieties in the molecule were synthesized and subjected to a biological screening (Schemes 2–7, Table 2). Carbamate juvenoids 1–4 were used as reference compounds for a detailed structure-activity study of their analogues. A clear relationship between the nature of the side chain functional group and the biological ...
