23 results about "Epicatechin gallate" patented technology

Epicatechin gallate (ECG) is a flavan-3-ol, a type of flavonoid, present in green tea. It is also reported in buckwheat and in grape. The tea component epicatechin gallate is being researched because in vitro experiments showed it can reverse methicillin resistance in bacteria such as Staphylococcus aureus. Nevertheless the compound is significantly degraded by steeping in boiling water, unlike related catechins.

Application of dehydrogenated epicatechin gallate combined with fluconazole in preparation of antifungal drugs

This invention relates to the field of pharmaceutical technology, specifically to the application of dehydronuciolin and fluconazole in the preparation of antifungal drugs. The in vitro synergistic effect of the combination of dehydronuciolin and fluconazole was determined using a checkerboard assay, showing a fractional inhibitory concentration (FIC) ≤0.5, confirming a strong synergistic effect. The in vivo efficacy of this drug combination was verified using a large wax moth infection model. Phenotypic experiments explored the synergistic mechanism, showing that the combination of dehydronuciolin and fluconazole significantly inhibited the hyphal growth, biofilm formation, and adhesion to host cells of drug-resistant Candida albicans. Transcriptome sequencing analysis confirmed these findings, showing that treatment with the combination of dehydronuciolin and fluconazole downregulated hyphae-specific genes, GPI-anchored cell wall proteins, and the ergosterol biosynthesis pathway, collectively weakening the virulence, surface integrity, and host recognition ability of Candida albicans, thereby reversing its drug resistance.
