一般描述
Hamamelitanninis a tannin derived from the bark and leaves of Hamamelis virginiana(witch hazel).
应用
Hamamelitannin can be used to study chromatography, aromatics, esters, hamamelis, heterocyclics, natural compounds, phenols, phytopharma standards, polyhydroxy compounds, and tannins. It also significantly reduces biofilm metabolic activity of the following bacteria: Staphylococcus epidermidis, Staphylococcus aureus, Acinetobacter baumannii, and Candida albicans strains. Hamamelitannin displays specific cytotoxic activity against colon cancer cells. It has been used in a study to determine that quorum-sensing inhibitors increase the success of antibiotic treatment by increasing the susceptibility of bacterial biofilms and/or by increasing host survival following infection.

Peroxynitrite (ONOO(-)) is a cytotoxicant with strong oxidizing properties toward various cellular constituents, including sulphydryls, lipids, amino acids and nucleotides and can cause cell death, lipid peroxidation, carcinogenesis and aging. The aim of this study was to characterize ONOO(-) scavenging

N-Nitrosodialkylamines are environmental alkylating carcinogens which are metabolically activated to alpha-hydroxy nitrosamines by cytochrome P450. The precise mechanism of their activation is not well understood, and a simplified chemical model for cytochrome P450 as a non-enzymatic system is useful for

Although the exact role of quorum sensing (QS) in various stages of biofilm formation, maturation, and dispersal and in biofilm resistance is not entirely clear, the use of QS inhibitors (QSI) has been proposed as a potential antibiofilm strategy. We
