Phenoxy herbicides and fibrates potently inhibit the human chemosensory receptor subunit T1R3.

J. Med. Chem. 52 , 6931-5, (2009)

We show that phenoxyauxin herbicides and lipid-lowering fibrates inhibit human but not rodent T1R3. T1R3 as a coreceptor in taste cells responds to sweet compounds and amino acids; in endocrine cells ...

Amphiphilic blockers punch through a mutant CLC-0 pore.

J. Gen. Physiol. 133(1) , 59-68, (2009)

Intracellularly applied amphiphilic molecules, such as p-chlorophenoxy acetate (CPA) and octanoate, block various pore-open mutants of CLC-0. The voltage-dependent block of a particular pore-open muta...

Molecular modeling of p-chlorophenoxyacetic acid binding to the CLC-0 channel.

Biochemistry 42(18) , 5176-85, (2003)

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 ...
