Using degassed pH 6.5 2-(N-morpholino)ethanesulfonic acid (MES)-buffered saline (MBS) with 10 mM ethylenediaminetetraacetic (EDTA) acid as a buffer, PGA stocks were prepared at 13.2 mg/mL (100 mM glutamate monomer). 4-(4,6-Dimethoxy-1,3,5-triazin-2-yl)–4-methylmorpholinium tetrafluoroborate (DMTMM; Sigma-Aldrich Co., St Louis, MO, USA) was added at 150 mol% relative to glutamate …
2021-01-01 · Tyr conjugation to HA was catalyzed by adding 5 mmol 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (DMTMM) (TCI Europe N.V.) coupling agent followed by 5 mmol Tyr (Sigma-Aldrich, St. Louis, MO), which was slowly added to the reaction. The reaction occurred at 37 °C under continuous stirring for 24 h. DMTMM or the amine concentration so that a specific degree of substitution or crosslinking is achieved. The stability of DMTMM has also been examined, and degradation studies of DMTMM in H2O at 50 °C with 1H NMR analysis show that 11% of the starting material remains after 48 hours. The reaction has proven to be an from Sigma-Aldrich.
Use of DMTMM chloride in organic solution is limited by its instability, as it undergoes self-immolative degradation. Its half-life is 120 min in DMSO, 15 min in DMF, and even shorter in Chloroform . A volume of 875 μl of each polysaccharide was treated with 70 μl of a 200 mg/ml solution of 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (DMTMM) (Sigma-Aldrich, MO, USA) in sterile water. The polysaccharide/DMTMM mixture was incubated in the dark, on a rotator, for 1 h at room temperature (RT). chloride (DMTMM; Sigma-Aldrich) as catalysts (28). Briefly, ht e lpi osomes of the above preparaoitn were incubaetd wh Rti GD and DMTMM (DSPE-PEG 2000-NH 2:RGD:DMTMM=1:1:1, molar ratio), and then the mixture was slightly stirred for 1 h at room temperature.

Use of DMTMM for bioconjugations has been reported at both alkaline (Pelet & Putnam, 2011) and acidic pH (Nimmo et al., 2011, Yu et al., 2014). In comparison, for the reaction at 56 °C M56111 performed without any further addition of DMTMM and amines during the whole duration of the reaction, a stable DS of around 20% for 4 days was observed, suggesting that the DMTMM is a limiting reagent in our reaction likely due to its inactivation.

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.
