The synthesis and stability of aziridino-glutamate, an irreversible inhibitor of glutamate racemase
摘要:
Aziridino-glutamate (2-(2-carboxyethyl)aziridine-2-carboxylic acid, (+/-)4) was synthesized by heating alpha-fluoromethylglutamate in base. In neutral solution, 4 was shown to cyclize to the gamma-lactone 5 with a half life of 4 minutes. Aziridino-glutamate was shown to irreversibly inactivate glutamate racemase by alkylating an active site cysteine residue, Electrospray mass spectrometry was used to establish that a covalent bond had famed and that this bond protects one of the enzyme's two cysteine residues from reacting with iodoacetate under denaturing conditions.

The syntheses of alpha-mono- and alpha-difluoromethyl derivatives of tryptophan and 5-hydroxytryptophan are described. In an attempt to selectively regulate serotonin synthesis, alpha-(mono- and difluoromethyl)tryptophan were tested in vivo as precursors (or prodrugs) of their 5-hydroxy analogues. Although alpha-(mono- and difluoromethyl)-5-hydroxytryptophans are potent irreversible inhibitors of aromatic
