Biological Activity

Description 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. [1] 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. [2] 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. [3] 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. [4]

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. [5] 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.

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
