Trimethyl Chitosan forms gels with multivalent anions and clear solutions that dry to strong, clear films. Its ideal for scaffolds, cell therapy, drug delivery, and biomedical applications. Its a water soluble natural biopolymer that’s biocompatible, biodegradable, antibacterial, and adhesive to tissue.
Quaternization of chitosan is a method of modifying and improving the properties and functionalities of chitosan. Quaternization of chitosan occurs by introducing a quaternary ammonium moiety onto or outside the chitosan backbone, via chemical reactions with primary amino and hydroxyl groups. The most established form of quaternized chitosan is N,N,N-trimethyl chitosan (TMC) and N-[(2-hydroxy-3-trimethyl ammonium) propyl] chitosan. By modifying chitosan through the insertion of a quaternary moiety, permanent cationic charges on the polysaccharide backbone results in improvements in many of chitosan’s beneficial properties, such as improved;
These Trimethyl Chitosan properties broaden chitosan’s applicability across a vast array of biomedical and pharmaceutical applications.
N,N,N-Trimethyl chitosan chloride (TMC) is a chemically modified chitosan with improved aqueous solubility, compared with the native chitosan. It is essential to follow a synthesis procedure in which the degree of substitution of the final product can be controlled by means of the number of reaction steps, the duration of each reaction step, and the amount of methyl iodide as reagent.
Positionally substituted 2′-O-hydroxypropyl trimethyl ammonium chloride chitosans with different substitution degree of quaternary ammonium salt played an important role as a high-performance antibacterial bio-resource polymer against E. coli and S. aureus…
Hydroxypropyl trimethyl ammonium chloride chitosan (O-2ʹ-HACC) was prepared as an adjuvant and mucosal immune delivery carrier for DNA vaccine loaded with Newcastle disease virus (NDV) F gene plasmid DNA and C3d6 molecular adjuvant (O-2ʹ-HACC/pFDNA microparticles). Findings indicated that the O-2ʹ-HACC could be used as a vaccine adjuvant and delivery system for mucosal immunity and have an immense application promise.
Gemcitabine is a nucleoside analog effective against a number of cancers. However, the full potential of this drug has not been realized, in part due to low oral bioavailability and frequent dosing requirements. This study reports the synthesis, in-vitro, ex-vivo and in-vivo evaluation of…
