The study aimed to prepare allicin in large quantities and evaluate the effects of different conditions and endogenous substances (polyphenols and free amino acids) in garlic on its stability. The optimized synthesis conditions of allicin (DADS:HAc = 2:9, HO:DADS = 2:1.6, reacted for 6.5 h) were established based on response surface design. Allicin with 92.57% purity was obtained by high-speed counter-current chromatography. The results of allicin degradation experiment indicated that the degradation rate of allicin accelerated with the increases of initial concentration and temperature, the degradation process of allicin was good fit with two first-order kinetics (R > 0.97). The stability of allicin was higher in pH 2-5.8 than in pH 8-9. Apigenin, myricetin, and quercetin combined with peroxidase enhanced the stability of allicin. Cysteine, arginine, and histidine could react with allicin. These findings provide insights for optimizing for allicin storage and food processing applications.

This study investigates a strategy to improve the osteogenic capacity of Ti6Al4V implants by incorporating allicin onto hydroxyapatite-coated implant surfaces. Allicin, a bioactive compound derived from garlic, is recognized for its ability to modulate bone remodeling processes. Hydroxyapatite (HA) coatings were applied by using plasma spraying, and allicin was loaded and its release was characterized using UV-vis spectroscopy.

Conventional miRNA-based diagnostic methods often treat all biomarkers equally, overlooking the fact that each miRNA contributes differently to disease classification. This differential diagnostic importance is captured by the concept of Cancerous Diagnostic Valence (CDV)-a metric that quantifies both the direction (oncogenic or protective) and magnitude of each miRNA's association with cancer. Here, we introduce a polymerase-based DNA molecular computing system that directly encodes and integrates CDVs to perform weighted molecular classification of non-small cell lung cancer (NSCLC).

Acrylamide (AA) is a byproduct of the Maillard reaction, with mitochondrial damage playing a pivotal role in mediating its hepatotoxicity. Allicin, a potent dietary phytochemical, has been used to mitigate the hepatotoxicity of AA. This study confirmed that allicin attenuated mitochondrial structural damage in AA-treated livers and AML-12 cells.

Phytonutrients are widely recognized for their protective health benefits in humans. Mounting studies suggest that dietary organosulfur compounds play a significant role in preventing various pathological conditions. Organosulfur compounds, such as diallyl disulfide, diallyl trisulfide, alliin, allicin, S-allyl cysteine, and sulforaphane, possess broad pharmacological activities, making them versatile therapeutic agents.
