制备方法与用途

简介

烟酸最早是从米糠和酵母中分离得到的。它不仅可以用作食品和饲料添加剂，近年来的研究还证明其在降血脂方面具有显著效果。尤其是对降低血液中的甘油三酯更为有效，同时也能减少血液中的胆固醇含量。4-溴烟酸作为一种重要的医药中间体，在医药领域有着广泛的应用。

用途

4-溴烟酸及其相关衍生物已被证实能够抑制链球菌、金色葡萄球菌、大肠杆菌和乳酸菌等多种细菌的生长。它对革兰氏阳性菌和阴性菌都具有抑制作用，但其抑制效果可以被烟酸竞争性地逆转。4-溴烟酸的主要作用是抑制辅酶母体（如烟酸、烟酰胺、烟酰胺核糖苷）的合成，而部分烟酰胺核糖苷合成辅酶的吸收则不受影响，并且其吸收量为2~3ug/mg。
