Ethyl 4-[2-(6-methyl-3-pyridyloxy)hexyloxy]benzoate (1) and ethyl 4-(2-phenoxyhexyloxy)benzoate (2), which induce precocious metamorphosis in larvae of Bombyx mori, a clear sign of juvenile hormone (JH) deficiency, showed JH activity when topically applied to allatectomized 4th instar larvae of B. mori. Compounds 1 and 2 induced precocious metamorphosis with doses at which they were effective as JH agonists.
