詳細

Hamamelitanninis a tannin derived from the bark and leaves of Hamamelis virginiana(witch hazel).

アプリケーション

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.

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
