Chemical Properties

WHITE TO SLIGHTLY BEIGE FINE CRYSTALLINE POWDER

Definition

ChEBI: An acetylenic compound that is propynoic acid in which the acetylenic hydrogen is replaced by a phenyl group.

Enzyme inhibitor

This mechanism-based (suicide) inhibitor (FWfree-acid = 146.15 g/mol; CAS 637-44-5) inactivates Fe(II)- and a-ketoglutarate-dependent dioxygenase (the latter catalyzing the hydroxylation of the herbicide 2,4- dichlorophenoxyacetic acid), with Ki = 38.1 μM and kinact = 2.3 min–1 , covalently modifting a side-chain functional group in the proteolytic fragment (166-AEHYALNSR-174) forming one side of the substratebinding pocket. Phenylpropioloc acid also inhibits esterase and phenylalanine ammonia-lyase.

Purification Methods

Crystallise the acid from *benzene, CCl4 (m 136o) or aqueous EtOH. The S-benzylisothiuronium salt has m 184-186o (from EtOH). [Beilstein 9 II 436, 9 III 3061, 9 IV 2327.]
