General description
Chemical structure: phenicole
Biochem/physiol Actions
作用机制:氯霉素通过与50S核糖体亚基结合并阻止氨酰基tRNA附着于核糖体来阻断肽基转移酶步骤,从而抑制细菌蛋白质的合成。 它还抑制线粒体和叶绿体蛋白的合成以及(p)ppGpp的核糖体形成,从而抑制rRNA的转录。
耐药性机制:使用氯霉素乙酰转移酶会使产物乙酰化并使其失活。
抗菌谱:这是一种针对革兰氏阳性和革兰氏阴性细菌的广谱抗生素,主要用于眼科和兽医目的。

Other Notes
通过结合到细菌核糖体的大亚基上以及通过阻断肽基转移从而抑制蛋白质的生物合成;氯霉素抗性是一种用于筛选真核细胞的有用遗传标记;抗性通常由氯霉素乙酰转移酶介导,但也存在例外;综述。

Chloramphenicol resistance-specifying plasmids from incompatibility groups P-1 and C did not encode chloramphenicol acetyltransferase (CAT). Expression of resistance was inducible by subinhibitory concentrations of the drug. The mechanism of resistance was thought to be a cytoplasmic membrane-located barrier to the

Proliferating cells require coordinated gene expression between the nucleus and mitochondria in order to divide, ensuring sufficient organelle number in daughter cells [1]. However, the machinery and mechanisms whereby proliferating cells monitor mitochondria and coordinate organelle biosynthesis remain poorly understood.

Two key events, namely adhesion and invasion, are pivotal to the occurrence of metastasis. Importantly, the 37 kDa/67 kDa laminin receptor (LRP/LR) has been implicated in enhancing these two events thus facilitating cancer progression. In the current study, the role
