The aim of this review is to outline the recent advances in chitosan molecular modeling, especially its usage as a prodrug or drug in a field of antibacterial, anticarcinogenic and antioxidant activity. Polymeric materials like peptides, polysaccharides and other natural products have recently attracted attention as biodegradabile drug carriers. They can optimize clinical drug application, minimize the undesirable drug properties and improve drug efficiency. They are used for the slow release of effective components as depot forms, to improve membrane permeability, solubility and site-specific targeting. Chitosan is such a prospective cationic polysaccharide which has shown number of functions in many fields, including bio medicinal, pharmaceutical, preservative, microbial and others. This article discusses the structure characteristics of chitosan, a number of factors such as degree of polymerization, level of deacetylation, types of quarternisation, installation of various hydrophilic substituents, metal complexation, and combination with other active agents. Biodegradable, non-toxic and non-allergenic nature of chitosan encourages its potential use as a carrier for drug delivery systems in all above mentioned targets. The use of chitosan prodrug conjugates is aimed at the site-specific transport to the target cells use, for example, a spacer tetrapeptide Gly-Phe-Leu-Gly, promotion of drug incorporation into cells via endocytosis, hybridization or synergism of two types of drugs or a drug with a bioactive carrier. The design of chitosan macromolecule prodrugs is also discussed.

“…When the products were applied as interior finishing coats, a reduction in formaldehyde content of the paint was observed [30]. The synthesis by emulsion polymerization of an acrylic resin with a quaternary ammonium salt (hybrid chitosan/acrylic resin emulsion) also resulted in better stability and less leaching due to better cross-linking between the acrylic resin particles [31]. Polyurethane paints could also be modified by the addition of chitosan/bentonite nanocomposites to improve antimicrobial properties [32].…”

Sodium carboxymethyl cellulose (CMC) is cross‐linked with pea protein isolate (PPI) to prepare pea protein isolate/sodium carboxymethyl cellulose (PPI/CMC) composite film by the diffusion method. The effects of the mass fraction of CMC on the mechanical properties and water resistance of PPI/CMC composite film are investigated. In the film containing 0.4% CMC, the water vapor permeability (1.43 × 10−7 g m (m2∙h∙Pa)−1) is significantly decreased, while the water contact angle value is elevated (55.76°). The tensile strength of the composite film is enhanced by 54.45%, while the elongation at break is increased by 23.30%. The film has excellent thermal stability and a homogenous structure. The remarkable changes may be attributed to new chemical interactions (hydrogen bonds) between CMC and PPI as revealed by Fourier transform infrared spectroscopy. Further, the composite film has great advantages in water resistance after comparison. The film is applied to the fresh bean skin, effectively blocking and reducing the tearing force between the fresh bean skin, and consequently easy separation after soaking in water for 20 min. Overall, the inclusion of CMC effectively solves the functional limitation caused by the hydrophilicity of PPI film, paving the way for its effective application as a novel edible packaging film in conventional foods.
