Application

L-Histidine methyl ester dihydrochloride can be used as a reactant to synthesize:
  • Imidazopyridine derivatives by Pictet-Spegler reaction with different aldehydes.
  • A metal-chelating ligand, N-methacryloyl-(l)-histidine methyl ester by reacting with methacryloyl chloride.
  • Zwitterionic polypeptide derivative by amidation reaction with poly (α,β-L-aspartic acid).

Two kinds of novel chiral molecular tweezers containing imidazoliums were synthesized from L-alanine, L-phenylalanine, and L-glutamic acid. They are constructed by the chiral imidazolium pincers and two different spacers which are 1,3-bis (bromomethyl)benzene and 2,6-bis(bromomethyl)pyridine, respectively.

L-Histidine methyl ester inactivates histidine decarboxylase in a time-dependent manner. The possibility was considered that an irreversible reaction between enzyme and inhibitor occurs [Recsei, P. A., & Snell, E. E. (1970) Biochemistry 9, 1492-1497]. We have confirmed time-dependent inactivation by
