产品描述

硫胺素的衍生物。在体内被快速吸收到并转化成硫胺素。

体外研究

Dibenzoyl Thiamine is a thiol-type thiamine composed of thiamine and benzoic acid. It is not decomposed by aneurinase (thiamine-decomposing enzyme), making it more suitable for food processing than thiamine hydrochloride

体内研究

A chronic toxicity study in male Wistar rats for 6 months at dietary levels of up to 1000 ppm, shows Dibenzoyl Thiamine to be without specific toxic effects. A teratogenicity study in rats show Dibenzoyl Thiamine to be without embryotoxic or teratogenic effects. Tests for mutagenicity in bacterial systems, in the dominant lethal assay and in an in vivo cytogenetics test show Dibenzoyl Thiamine to be without mutagenic. Dibenzoyl Thiamine is metabolised to Vitamin Br and benzoic acid, and the benzoic acid moiety is almost quantitatively excreted in the urine, as hippuric acid

 

推荐实验方法(仅供参考)

Animal Administration

Rats: Groups of 65 male and 65 female Sprague-Dawley rats are fed diets containing Dibenzoyl Thiamine at levels of 1000 ppm (Group 1) and 10000 ppm (Group 2). A third group is fed a control diet. The animals are assigned by computer to groups on the basis of body weight, such that mean body weights in all groups are approximately equal. 10 Animals from each group are killed at 52 weeks, the remaining animals at week 105. All signs of ill-health or reaction to treatment are recorded daily. The animals are weighed at weekly intervals
