(3S,5R,9R,10R,13R,17R)-3,14-二羟基-10,13-二甲基-17-[(2R)-6-甲基庚烷-2-基]-2,3,4,5,9,11,12,15,16,17-十氢-1H-环戊二烯并[a]菲-6-酮 | 5β-ketodiol | 39219-57-3 | C27H44O3 | 416.645 |
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.
