Poly- -D-glutamic Acid Capsule Covalently Coupled to a. Protein Carrier DMTMM-mediated coupling was much cleaner, showing only maleim- ide and proton
DMTMM proved to be a better reagent than DCC for coupling the amine to benzoic acid.[7] All compounds were prepared in high yields (>68%). (C) Hyun and colleagues have reported the synthesis of mono-, di-, and triazidated polyrotaxanes from polyethylene glycol (PEG) and the azidated α-cyclodextrins using DMTMM as coupling reagent.[8]

Both ways provide the same the desired glucuronic acid amide, but DMTMM as coupling reagent requires less the Schotten-Baumann procedure,the Weinreb amidation of esters and the classical coupling reaction using EDC,HBTU or DMTMM as the coupling agents. 1 Jul 2014 We tested the more reactive coupling reagent, DMTMM (23), for coupling hydrazides to carboxylic acids in proteins and protein complexes (Fig. a peptide-coupling reagent has particularly attracted organic chemists in DMTMM. 4-(4,6-dimethoxy[1,3,5]triazin-2-yl)-4- methylmorpholinium chloride.

results of this coupling chemistry with those obtained with EDC coupling, the data indicate that, although EDC only showed significant coupling of ADH to the peptide under acidic con-ditions up to a pH of 5.8, DMTMM also allowed the reaction at near-neutral pH of 7.4 in PBS buffer (Fig. S1).

DMTMM (4- (4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methyl-morpholinium chloride) is an organic triazine derivative commonly used for activation of carboxylic acids, particularly for amide synthesis. Amide coupling is one of the most common reactions in organic chemistry and DMTMM is one reagent used for that reaction.

Here we demonstrate the applicability of 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (DMTMM) as an alternative coupling agent to synthesize HA-Tyr conjugates. The optimized derivatization process allows accurate control of the degree of substituted Tyr on hyaluronan (DSmol).
