  名称：

  (p-Sulfomethyl)phenylalanine as a mimic of O-sulfatyl-tyrosine in synthetic partial sequences of P-Selectin glycoprotein ligand 1 (PSGL-1)

  摘要：

  Fmoc-L-(p-sulfomethyl)phenylalanine, a bioisosteric mimic of acid-sensitive O-sulfatyl tyrosine, was synthesized from L-tyrosine according to a novel route. Partial sequences of the recognition site of P-Selectin glycoprotein ligand 1 (PSGL-1), which contain (sulfomethyl) phenylalanine were synthesized on solid-phase. By fragment condensation, a sialyl Lewis(x) peptide conjugate containing a (sulfomethyl)phenylalanine mimic of O-sulfatyl tyrosine was prepared without destruction of the acid-sensitive fucoside bond within the saccharide side chain. Compounds of this type are of interest as sufficiently acid-stable potential inhibitors of P-Selectin in inflammatory processes. (c) 2007 Elsevier Ltd. All rights reserved.
