一般描述

化学结构:磺胺

应用

磺胺噻唑是一种短效磺胺药。在发现毒性较低的替代品之前,它是一种常见的口服和外用抗生素。它不再用于人类。在实验动物的饮食中加入磺胺噻唑可抑制肠道细菌形成叶酸。这确保了动物可用叶酸的唯一来源是它们的饮食。

包装

100 g in poly bottle

生化/生理作用

磺胺噻唑是一种磺胺类抗生素,通过抑制二氢丙酸合成酶来阻断二氢叶酸的合成。磺胺噻唑是细菌对氨基苯甲酸(PABA)的竞争性抑制剂,它是细菌合成叶酸所必需的。它对革兰氏阳性细菌、革兰氏阴性细菌和衣原体均具有抗性。抗性产生机制是通过改变二氢蝶酸合成酶或叶酸合成的替代途径。

Poor folate status is associated with cognitive decline and dementia in older adults. Although impaired brain methylation activity and homocysteine toxicity are widely thought to account for this association, how folate deficiency impairs cognition is uncertain. To better define the
