4-氯苯氧乙酸下游产品

4-氯苯氧乙酸制备

【方法一】
由苯酚与氯乙酸缩合后，经氯化而得。1.缩合将熔化的苯酚与15%氢氧化钠溶液混合，又将氯乙酸水溶液加碳酸钠中和，两者投入反应锅混合，加热回流4h。反应毕，加盐酸调至pH为2-3，搅拌冷却，结晶，过滤，冰水洗涤，干燥，得苯氧乙酸。2.氯化将苯氧乙酸和冰醋酸混合搅拌溶解，加入碘片，在26-34℃通氯。通氯结束后放置过夜，次日在冷水中析出结晶，过滤，用水洗至中性，干燥得成品。

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 ...
