In vitro

SL327 is a water soluble, structural homologue of the specific MKK1/2 inhibitor U0126 with IC50 of 0.18 μM and 0.22 μM for MEK1 and MEK2 respectively. SL327 has no effect on a variety of other kinases, including PKA, PKC, or CamKII. [1]

In vivo SL327 (50 mg/kg) crosses the blood-brain barrierand and blocks fear conditioning by inhibiting MAPK/ERK phosphorylation. [2] SL327 (30 mg/kg) significantly impairs spatial learning in mice. [3] SL327 (50 mg/kg) blocks cocaine-induced properties. [4]

Protocol

Animal Research:[1]

  • Animal Models: Fear conditioning experiments in male Spague-Dawley rats.
  • Formulation: DMSO
  • Dosages: 10-100 mg/Kg
  • Administration: i.p.
    (Only for Reference)

Solubility (25°C)

In vitro DMSO 67 mg/mL (199.79 mM)
Ethanol 7 mg/mL (20.87 mM)
Water Insoluble
In vivo Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):

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)

*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.
