Apexbio Technology LLC Uniconazole 83657-22-1 10g

Uniconazole (CAS 83657-22-1) is a small-molecule inhibitor of cytochrome P450 707A enzymes (CYP707As) which are involved in the catabolism of abscisic acid (ABA) via 8 -hydroxylation In in vitro assays uniconazole demonstrated potent inhibition of CYP707A3 activity with a reported Ki of 68 nM surpassing other plant growth retardants such as paclobutrazol and tetcyclacis In Arabidopsis models uniconazole treatment elevated endogenous ABA levels and enhanced drought tolerance effects that were independent of gibberellin-mediated pathways Uniconazole is therefore utilized in plant biology research to study ABA metabolism and stress responses
