Synthesis, spectroscopic characterization, DFT studies, and antibacterial and antitumor activities of a novel water soluble Pd(II) complex with l-alliin

pH-responsive starch-based bilayer film functionalized with alliin loaded MIL-101 (Fe) for active food packaging

Food packaging films containing antimicrobial reagents play a crucial role in preventing bacterial-induced fruit decay. This study proposes a bilayer film consisting of an internal amino-modified starch hydrophilic layer and an external amino-modified polyvinyl alcohol/polylactic acid hydrophobic layer, embedding alliin@MIL-101(Fe) as an antibacterial agent, utilizing the pH reduction of fruit decay sites to achieve pH-responsive release, enhancing antibacterial performance. Fourier transform infrared (FTIR) and scanning electron microscopy (SEM) analyses confirm successful crosslinking between amino and aldehyde groups, resulting in the formation of imine bonds and a mesh-like structure conducive to adsorption. Under acidic conditions, the cumulative release rate of alliin reached 74 % within 36 h. Compared to a simple mixture, the tensile strength of the alliin@MIL/NST-NPVA/PLA film reached 34.771 MPa, and transmittance in the wavelength range of 200-370 nm decreased to 0. The scavenging rate of DPPH free radicals in the film can reach 83 %. In addition, the water vapor permeability and oxygen permeability of the film are approximately 7.62 × 10-16 [g/ (m2‧24 h‧0.1 mm)] and 6.83 (m2‧24 h‧0.1 MPa), respectively; moisture content and water solubility decreased to 10.99 % and 20.77 %. This composite film extended the shelf life of strawberries from 2 to 7 days, significantly enhancing freshness.

Research and application of leek roots in medicinal field

Some Chinese herbs have been used to prevent and treat diseases, and are also used as common food ingredients. These Chinese herbs are potential resource for research and development of new drugs. Leek roots is a typical medicine of food and medicine continuum. It has a long history of medicinal applications and edible food in China. In this paper, the origin, biological active components, pharmacological action and clinical application of leek roots were introduced. We hope that this review will contribute to the development of leek roots for pharmaceutical research and clinical applications, as well as related health products.

Type of complex–BSA binding forces affected by different coordination modes of alliin in novel water-soluble ruthenium complexes

Synthesis, characterization and interaction with BSA and apo-transferrin of novel water-soluble ruthenium complexes having differently coordinated alliin (S-allyl-l-cysteine sulfoxide).

Investigating the chemical constituent and the suppressive effects of alliin hydrolysate on E.coli

The present study investigates the antimicrobial activity of alliin degradation products by enzymatic and alkali-heat treatment. The results suggested that the suppressive effect of enzymatic degradation products (AE) on Escherichia coli was much higher than alkali-heat treatment products (AA). Both AE and AA seriously destroyed the integrity of E. coli cell membrane, decreased the utilisation of intracellular proteins and the absorption of extracellular phosphorus. Furthermore, GC-MS analysis preliminarily confirmed that alliin degradation products contained a variety of sulphur compounds, such as allyl disulphide and dithiene. The antibacterial activities exhibited by AE demonstrate their potential for use as E. coli inhibitor in food.

On the Dimers Stability of Allicin and Its Derivatives Interacting with AT, GC, and DNA Bridge: DFT Study

Allicin and its derivatives are physiologically active molecules with many potential health benefits. It is not clear if they have a direct effect on DNA or protein. In order to elucidate the allicin and its derivatives’ effect on DNA base pairs, we investigated various complexes of base pair and its bridge with an allicin and its derivatives. The investigated allicin derivatives were (E)-Ajoene, (Z)-Ajoene, Amz121, and Bmz73 radicals. The DFT calculation results revealed that the investigated molecules would favor binding to bridge of the base pairs instead of directly affecting the base pairs. The Bmz73 radical could break DNA by change bonding in it because the Bmz73 radical significantly affected the P-O bond of the bridge of base pair.
