Application

4-Chlorophenoxyacetic acid has been used in para-chlorophenoxyacetic acid (p-CPA) residue assay.
4-chlorophenoxy acetic acid (4-CPA), a chlorine derivative of phenoxyacetic acid (PA), is a plant growth regulator used as a herbicide.

Biochem/physiol Actions

4-Chlorophenoxyacetic acid is a synthetic auxin, that is used to induce parthenocarpic ovary growth on flowers of wild type plants.

Molecular simulation techniques were applied to predict the interaction of the CLC-0 Cl(-) channel and the channel-blocking molecule p-chlorophenoxyacetic acid (CPA). A three-dimensional model of the CLC-0 channel was constructed on the basis of the homology with the bacterial Cl(-)

The Torpedo Cl- channel, CLC-0, is inhibited by clofibric acid derivatives from the intracellular side. We used the slow gate-deficient mutant CLC-0C212S to investigate the mechanism of block by the clofibric acid-derivative p-chlorophenoxy-acetic acid (CPA). CPA blocks open channels with
