Abstract
A number of ecdysone analogues were prepared to study the effect of structural changes on biological activity. It was found that analogues with the 5α-configuration or a 3,5-cyclo structure were inactive, that a 3β-hydroxy group enhances activity but is not essential for activity, and that 3β-substituents decrease activity as follows: OMe (60%), OAc (25%) and OEt (10%). The keto diol (3), keto alcohol (9) and amide (36) were found to be highly toxic to mosquito larvae.
