Janus cykliska peptid-polymer nanorör - naturkommunikation

Methods2.2.1. Although presently DMTMM is quite expensive, we estimated a price of 4.0–4.5 €/kg to produce DMTMM. This figure has been calculated, based on the synthetic procedure reported by M. Saijo ( Saijo and Hirano, 2002 ), summing to the bill of materials (3.0–3.3 €/kg) production costs of about 1.0–1.2 €/kg (25% of the material costs). DMTMM-mediated amidation of HA proceeds through an aromatic substitution forming an intermediate s-triazine ester of HA reactive towards amines (compound 1, Scheme 1).

DMTMM-mediated ligation is a new promising chemical tool to synthesize HA derivatives for biomedical and pharmaceutical applications. (TCEP, Sigma-Aldrich, Cat. Long-term expansion Moreover, CMC fulfils minimum requirements necessary for the use of DMTMM containing both carboxylic and hydroxyl groups on the polymeric chain. 2. Material and methods2.1.

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.

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.
