摘要:
We enlarged the uniconazole (UNI) molecule to find a specific inhibitor of abscisic acid (ABA) 8'-hydroxylase, and synthesized various UNI derivatives that were substituted with hydrophilic and hydrophobic groups at the 4-chlorine of the phenyl group of UNI using click chemistry. Considering its potency in ABA 8'-hydroxylase inhibition, its small effect on seedling growth, and its ease of application, UT4, the UNI derivative containing the C-4 alkyltriazole, was the best candidate for a highly selective inhibitor of ABA 8'-hydroxylase.
