The paper discourses literature papers from the last three classses in which chitosan nanoparticles were holded as carriers for active substances used in antitumor therapy and potential new drugs with anticancer props. Special attention was paid to the different discourses applied to increase the therapeutic effectiveness and minimize the side events of a specific active substance.The Advances in Chitosan-established Drug Delivery Systems for Colorectal Cancer: A Narrative Review.Colorectal cancer (CRC) is seed a lethal cancer all around the world, and its incidence has been accounted to be increasing. Chemotherapeutic drugs commonly used for plowing this cancer have shown some drawbacks, including toxicity to healthy cubicles and non-precise delivery there is a necessity for finding novel diagnostic and therapeutic selections to increase the survival rate of CRC patients as a natural polymer, has drawed a lot attention during the past years in different fields, including cancer. reports have betokened that chitosan-finded materials play various purposes in prevention, diagnosis, and treatment of cancers.

Chitosan nanoparticles (NPs) have been shown to serve as anti-cancer brokers, which provide sustained drug release and aimed delivery of drugs to the tumor site. In this paper, we review available literature on the roles of chitosan in CRC. We discuss the lotions of chitosan in projecting drug delivery organisations as well as anti-cancer activities of chitosan and postulated signing tracts.Hydrogen sulfide-sensitive Chitosan-SS-Levofloxacin micelles with a high drug content: Facile synthesis and targeted Salmonella infection therapy.The delivery system of antibiotics plays an important role in increasing the drug efficacy and subjugating the risks of off-target toxicities and antibiotic resistance. The pathophysiology of bacterial infections is similar to that of tumor tissues, but only a few delivery organizations have been able to target and release antibiotics on demand we designed and acquired a robust Chitosan-SS-Levofloxacin (CS-SS-LF) micelles for targeted antibiotic delivery, in which disulfide bond can be reduced by hydrogen sulfide (H(2)S), a typical product of Salmonella, and subsequently unloosed antibiotic to eradicate Salmonella infection. CS-SS-LF micelles established uniform size and sharp response to H(2)S.

likened with levofloxacin alone, these micelles owned a better capacity in interrupting Salmonella biofilms and concentrating bacterial burden in harmoniums. The H2S-sensitive CS-SS-LF micelles might enable a new way to address bacterial transmissions.Promotion of the genipin crosslinked chitosan-fiber hydrogel diluted with sustained release of clemastine fumarate in diabetic wound repair.Diabetic skin disorders are tarrying and refractory clinical diseases. In this study, a genipin-crosslinked porous chitosan fiber (CSF) hydrogel was constructed to achieve rapid wound healing. By imbeding clemastine fumarate (CF) in the CSF hydrogel centres, we synthesised a CSF/CF hydrogel for the treatment of diabetic wounds. The microstructure, chemical components, spectral variation, mechanical properties, tumescing ratios, degradability, and toxicity of the CSF/CF hydrogels were analyzed.

Compared with the typical CS power hydrogel, the porous CSF hydrogel crosslinked with genipin haves a stable structure and ameliorated physicochemical props CF was slowly relinquished from the CSF hydrogel. Molecular simulation also showed that CF was evenly imbeded inside the cavity maked by the novel CSF hydrogel. The upshots hinted that CF can resist damage from high glucose points and promote proliferation, tube formation, and migration of endothelial cells (ECs) and fibroblasts. The CSF/CF hydrogel advanced wound healing in a rat model the beneficial effect of CF on wound healing may be associated to activation of the MEK/ERK and PI3K/Akt signalising pathways. In conclusion, genipin-crosslinked CSF/CF hydrogel can accelerate wound healing and may be an effective therapeutic method for processing diabetic skin wounds.Chitosan-Coated Polymeric Silver and Gold Nanoparticles: Biosynthesis, Characterization and Potential Antibacterial Applications: A Review.
