  Abscinazole-F1, a conformationally restricted analogue of the plant growth retardant uniconazole and an inhibitor of ABA 8′-hydroxylase CYP707A with no growth-retardant effect

  摘要：

  To develop a specific inhibitor of abscisic acid (ABA) 8'-hydroxylase, a key enzyme in the catabolism of ABA, a plant hormone involved in stress tolerance, seed dormancy, and other various physiological events, we designed and synthesized conformationally restricted analogues of uniconazole (UNI), a well-known plant growth retardant, which inhibits a biosynthetic enzyme (ent-kaurene oxidase) of gibberellin as well as ABA 8'-hydroxylase. Although most of these analogues were less effective than UNI in inhibition of ABA 8'-hydroxylase and rice seedling growth, we found that a lactol-bridged analogue with an imidazole is a potent inhibitor of ABA 8'-hydroxylase but not of plant growth. This compound, abscinazole-F1, induced drought tolerance in apple seedlings upon spray treatment with a 10 mu M solution. (C) 2009 Elsevier Ltd. All rights reserved.

The chiral performance of TBCDP was evaluated by using chiral pesticides and drugs as probes including triazoles, flavanones, dansyl amino acids and β‐blockers. Some effects of the composition in mobile phase and pH value on the enantioseparations were investigated in different modes. The nine triazoles, eight flavanones, and

  The plant growth retardant S-(+)-uniconazole (UNI-OH) is a strong inhibitor of abscisic acid (ABA) 8'-hydroxylase, a key enzyme in the catabolism of ABA, a plant hormone involved in stress tolerance, stomata] closure, flowering, seed dormancy, and other physiological events. In the present study, we focused on the two polar sites of UNI-OH and synthesized 3- and 2 ''-modified analogs. Conformational analysis and an in vitro enzyme inhibition assay yielded new findings on the structure-activity relationship of UNI-OH: (1) by substituting imidazole for triazole, which increases affinity to heme iron, we identified a more potent compound, IMI-OH; (2) the polar group at the 3-position increases affinity for the active site by electrostatic or hydrogen-bonding interactions; (3) the conformer preference for a polar environment partially contributes to affinity for the active site. These findings should be useful for designing potent azole-containing specific inhibitors of ABA 8'-hydroxylase. (C) 2007 Elsevier Ltd. All rights reserved.
