Biological Activity

Description Imipenem acts as an inhibitor of AmpC β-lactamase and is an antibiotic useful for the treatment of a number of bacterial infections.
Targets
AmpC β-lactamase [1]
()
In vitro

Imipenem, a β-lactam antibiotic, binds to penicillin binding protein 2 with the highest affinity and produces rounded cells. The binding of imipenem causes cells to lyse quickly and thereby to release less free endotoxin[1].

In vivo Imipenem has a very short half-life[1]. Imipenem has antimycobacterial activity both in a mouse model and in humans at high risk for failure of treatment for MDR (multiple-drug-resistant) tuberculosis[2].

Protocol

Animal Research:[1]
- Collapse
  • Animal Models: BALB/c mice
  • Dosages: 50, 75, and 100 mg/kg
  • Administration: i.p.
    (Only for Reference)

Solubility (25°C)

In vitro Water 63 mg/mL (198.51 mM)
DMSO 1 mg/mL (3.15 mM)
Ethanol Insoluble

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

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

    Volume
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / 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 )

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.
