Synthesis and biological activity of abscisic acid esters

Abstract 16 ABA esters including 11 new compounds were prepared by two different esterification routes. All the structures of ABA esters were confirmed by 1H NMR, 13C NMR and HRMS. Their biological activity and hydrolysis stability were investigated. Fortunately, there were 15 and 9 compounds which displayed much better or nearly the same inhibition activity for rice seedling growth and Arabidopsis thaliana seed germination compared to ABA, respectively. Especially, compounds 2d and 2g showed better biological activities than ABA in the three tests. Moreover, we found that chemical hydrolysis ability of the esters in vitro had little relationship to their biological activity.

Electrolytic reduction of abscisic acid methyl ester and its free acid

Abscisic acid (ABA, 1), a plant hormone, has electrophilicity derived almost entirely from the side-chain, 3-methylpenta-2,4-dienoic acid. The electrochemical property of ABA was investigated by analysis of its cathodic reaction. ABA methyl ester (1-Me) w

Asymmetrical ligand binding by abscisic acid 8′-hydroxylase

Abscisic acid (ABA), a plant stress hormone, has a chiral center (C1′) in its molecule, yielding the enantiomers (1′S)-(+)-ABA and (1′R)-(-)-ABA during chemical synthesis. ABA 8′-hydroxylase (CYP707A), which is the major and key P450 enzyme in ABA catabol

Synthesis and biological activity of 4'-methoxy derivatives of abscisic acid

Replacing the 4'-carbonyl group of abscisic acid with a methoxy group does not affect the abscisic acid (ABA)-like activities of the product in barley aleurone protoplasts, although the reduction of ABA to 4'-hydroxyl derivatives significantly reduces the

Simple methods for the preparation of enantiomerically pure abscisic acid (ABA) analogues from (S)-(+)-ABA
