Biological Activity

Description Bismuth Subcitrate is an antibiotic used to treat stomach ulcers associated with Helicobacter pylori, a bacterial infection.
In vitro

Colloidal Bismuth Subcitrate is crystallized in dilute HCl at pH 3, and unique assembly of three basic bismuth citrate dimeric units ([Bi(cit)2Bi]2-) leads to the formation of two-dimensional sheets and 3D polymer, the solubility of Colloidal Bismuth Subcitrate in water is found to be dramatically affected by pH, from >70 mg/mL at pH 7 to only about 1 mg/mL at pH 3. [1] Bismuth Subcitrate is effective against the 12 C. pyloridis strains with MIC50 of 8 μg/mL. Bismuth Subcitrate combined with oxolinic acid exhibits synergistic activity against the 12 C. pyloridis strains. [2] Colloidal bismuth subcitrate (5 mg/mL) significantly increases the frequencies of sister-chromatid exchange (SCE) and micronucleus rate in peripheral lymphocytes compared with controls in human whole blood cultures. [3] Bismuth Subcitrate (100μM) inhibits Helicobacter pyloriF1-ATPase activity, and inhibition is prevented and reversed by the mercaptan glutathione, indicating that Bismuth Subcitrate interfere with sulfhydryl groups of the enzyme. [4] Colloidal Bismuth Subcitrate (150 mg/mL) inhibits the lipolytic activity of C. pylori filtrate, causing a 21% reduction in lipase activity and a 60% reduction in the activity of phospholipase A.

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.
