Chloramphenicol 是一种 (bacterial) 感染的广谱抗生素,作为细菌蛋白质生物合成的有效抑制剂。Chloramphenicol 主要作用于细菌 70S 核糖体的 50S 亚基,通过抑制肽基转移酶活性来抑制肽键的形成。
Information
Chloramphenicol Chloramphenicol (Chloromycetin) is a bacteriostatic by inhibiting protein synthesis.
In vitro
Chloramphenicol results in a constitutive increase in the level of cspA transcript and constitutive production of CS7.4. Chloramphenicol down-regulates the mitochondrial DNA-encoded Cox I protein, but not nuclear-encoded proteins. Chloramphenicol increases cellular levels of the p21(waf1/cip1) protein and p21(waf1/cip1) mRNA through a p53-independent pathway. Chloramphenicol, at concentrations greater than 0.1 g/L (0.3 mM), inhibits the denitrifying enzyme activity (DEA) of slurries of humisol and sandy loam soils by disrupting the activity of existing nitrate reductase enzymes. Chloramphenicol, at concentrations from 5 mM to 2 mM initiates apoptosis in dividing cells from a monkey kidney-derived cell line and in haematopoietic progenitor cells from human neonatal cord blood. Chloramphenicol suppresses growth of progenitor cells.
In vivo
Chloramphenicol results in increased t1/2(beta) (by 209%), and decreased ClB (by 45%), and prolonged recovery indices (by 768 to 946%) in greyhounds. Chloramphenicol suppresses increases in the body weight and liver weight of experimental animals and at the same time induced a remarkable increase in lipid peroxidation in the liver during the formation of megamitochondria. Chloramphenicol-induced formation of megamitochondria is not simply ascribed to the suppression of the dividing process of mitochondria due to lowered protein synthesis in mitochondria but is intimately related to oxidative stress.
