An improved preparation of 4-hydroxymethyl-L-phenylalanine
Morera, Enrico,Ortar, Giorgio,Varani, Aurelio
, p. 4279 - 4285 (1998)
Palladium-catalyzed hydroformylation of methyl esters of N-Boc-L- tyrosine triflate (1a) and N-Boc-4-iodo-L-phenylalanine (1b) followed by reduction with sodium borohydride and standard deprotection procedures affords the title compound in 77 and 83% over
Intrinsic deuterium isotope effects on benzylic hydroxylation by tyrosine hydroxylase
Frantom, Patrick A.,Pongdee, Rongson,Sulikowski, Gary A.,Fitzpatrick, Paul F.
, p. 4202 - 4203 (2002)
Tyrosine hydroxylase (TyrH) is a mononuclear, non-heme iron monooxygenase that catalyzes the pterin-dependent hydroxylation of tyrosine to dihydroxyphenylalanine. When 4-methylphenylalanine is used as a substrate for TyrH, 4-hydroxymethylphenylalanine is

, (2010/06/16)
The invention relates to a compound of the formula (I): in which k and j are independently 0 or 1, Y is a macrocycle in which the cycle includes 9 to 36 carbon atoms and is functionalised by three amino functions and by a chain for attaching the spacer arm Z via an X bond, Rc is a binding pattern with a receptor of the TNF superfamily, X is a chemical function for binding the Y group to the space arm, and Z is a bi-, tri- or tetra-functional spacer arm.

The invention concerns a compound of formula (I), wherein Y represents a macrocycle whereof the cycle comprises 9 to 36 atoms, and is functionalized by three amine or COOH functions; Rc represents a group of formula H—Xa—Xb—Xc—Xd—Xe—(Xf)i—, wherein i represents 0 or 1, Xn is in particular selected among lysine, arginine, ornithine residues, Xb is in particular selected among glycine, asparagine, L-proline or D-proline residues, Xc et Xd are in particular selected among tyrosine, phenylalanine or 3-nitrotyrosine residues, Xe et Xf are in particular selected among the following amino acid residues: NH2—(CH2)n—COOH, n ranging from 1 to 10 or NH2—(CH2—CH2—O)m—CH2CH2COOH, m ranging from 3 to 6, provided that one at least of the amino acid residues Xa, Xb, Xc and Xd is different from the corresponding amino acid in the sequence of the natural CD40 143Lys-Gly-Tyr-Tyr146 fragment
(p-Sulfomethyl)phenylalanine as a mimic of O-sulfatyl-tyrosine in synthetic partial sequences of P-Selectin glycoprotein ligand 1 (PSGL-1)
Herzner, Holger,Kunz, Horst
, p. 6423 - 6436 (2008/02/04)
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 cont
Synthesis of novel chiral amino acids possessing a porphyrin moiety
Tamiaki, Hitoshi,Onishi, Motoki
, p. 1029 - 1032 (2007/10/03)
Phenylalanine derivatives bearing a porphyrin moiety at the para- position were prepared in an enantiomerically pure form. The synthetic nonnatural aromatic amino acid reacted with amines and acids to give novel functionalized peptides without loss of the
