4-bromo-N-(pyridin-2-ylmethyl)naphthalene-1-sulfonamide Usage And Synthesis

Uses

Pyrabactin has been used to form a homogeneous complex of PYL3?pyrabactin for the protein purification by size-exclusion chromatography.

Definition

ChEBI: A sulfonamide obtained by formal condensation of the sulfo group of 4-bromonaphthalene-1-sulfonic acid with the exocyclic amino group of 2-pyridylmethylamine. Mimics the action of the abscisic acid, a phytohormone.

Biochem/physiol Actions

Pyrabactin is a synthetic plant growth inhibitor that acts as a seed-selective abscisic acid (ABA) agonist. Pyrabactin acts through Pyrabactin Resistance 1 (PYR1), the founding member of a family of START proteins called PYR/PYLs, which are necessary for both pyrabactin and ABA signaling in vivo. Eventually, it is hoped to lead to a compound that could be sprayed on crops to protect them from drought.
