Application

4-(4,6-Dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium tetrafluoroborate (DMTMM BF4) can be used as a coupling reagent alternative to DMTMM Cl in peptide synthesis because of its stability. It is also used in the synthesis of:
  • Esters and peptides in both solution and solid-phase.
  • γ-aminobutyric acid (GABA)-containing cyclic heptapeptide, unguisin A.
  • The cyclization of linear tetrapeptides.

Indoleamine 2,3-dioxygenase (IDO) is an immunomodulating enzyme that is overexpressed in many cancers with poor prognosis. IDO suppresses T cell immunity by catabolizing tryptophan into kynurenine (KYN), which induces apoptosis in T effector cells and enhances T regulatory cells, providing

The ability of gelatin-based hydrogels of incorporating and releasing under controlled conditions 5,6-dihydroxyindole-2-carboxylic acid (DHICA), a melanin-related metabolite endowed with marked antioxidant properties was investigated. The methyl ester of DHICA, MeDHICA, was also tested in view of its higher stability
