pH sensitivity of chitosan allows for precise phase transitions in acidic environments, controlling swelling and shrinking, making suitable drug delivery systems. are modulated by the presence cross-linkers functionalization chain. This review relays a summary tailoring to optimize release. The potential customize different environments therapeutic uses introduces opportunities encapsulation focus on improving sustained release specific tissues is an advanced interpretation, reflecting evolving role achieving targeted more efficient outcomes. describes strategies improve solubility stability ensure controlled encapsulated drugs. discussion optimizing factors like cross-linking density, particle size, deeper understanding how achieve effects. These represent refined approach designing chitosan-based systems, pushing boundaries technologies offering new avenues profiles.

Antifungal Activity of Vanillic Acid Grafted Chitosan Derivatives against Plant Pathogenic Fungi, Fusarium sp.

ACS Agricultural Science & Technology, Год журнала: 2024, Номер 4(10), С. 1083 - 1101

Опубликована: Окт. 8, 2024

The present work aimed to obtain chitosan derivatives with greater solubility in water, good physicochemical properties, and potent antifungal activity against plant pathogens. In this study, the modification of (CS) vanillic acid (VA) was achieved via free radical grafting by optimizing VA CS ratio. grafted (VA-g-CS) samples were characterized, their toward Fusarium solani proliferatum evaluated. All VA-g-CS demonstrated successful conjugation between VA, different degrees, altered surface morphology, improved water solubility. results indicated that a mass ratio 0.5:1 exhibited highest content (74.6 ± 1.42 mg VAE/g) an amino substitution percentage 50.3 0.54%. Increasing concentration from 1.0 5.0 mg/mL enhanced activity. Furthermore, (0.5:1) at showed better than other CS, more 80 76% inhibition F. proliferatum, respectively. offers new strategy for controlling pathogenic fungi.

Preservative for High Antioxidant and Antimicrobial Activity and Low Toxicity

Langmuir, Год журнала: 2024, Номер 40(49), С. 26055 - 26066

There is an urgent need for highly efficacious and minimally toxic preservatives vegetables fruits to ensure extended freshness safety. Using natural polymer starch as the matrix, we produced nicotinated starch-ethylamine (NSA) based on N,N′-carbonyldiimidazole (CDI) acting catalyst 2-chloroethylaminehydrochloride nucleophile. To strengthen antimicrobial antioxidant activity, NSA was reacted with three different cinnamic acids prepare derivatives bearing cinnamyl (CNSA, DNSA, ENSA). With a grafting rate of 27%, ENSA demonstrated notable capability reaching ∼85% at 1.6 mg/mL. Also, it displayed inhibitory indices 88.14%, 89.11%, 77.90% against Botrytis cinerea, Phomopsis asparagi, Glomerella cingulate, respectively, concentration 1.0 The cytotoxicity test showed that 293T cell survival ratio reached 101.5%. In addition, sample able extend shelf life cherry tomatoes by days. This study has successfully developed novel starch-based preservative not only possesses excellent properties but also effectively extends produce, demonstrating its broad application prospects in field fruit vegetable storage preservation.
