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.

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
