Biological Activity

Description Efonidipine (NZ-105) is an L- and T-type calcium channel blocker leading to vasodilation and decreased automaticity of the heart. It also suppresses aldosterone secretion from the adrenal.
T-type calcium channel [2]
In vitro

Although efonidipine is not a specific T-type calcium channe (TTCC) blocker as it could also block L-type calcium channe (LTCC), its efficacy in blocking TTCC is much greater than that of LTCC[1]. Efonidipine exerts an inhibitory effect on aldosterone synthesis and secretion in a human adrenocortical cell line (H295R), an effect that is mediated, at least in part, by suppression of 11-β-hydroxylase and aldosterone synthase expression. Efonidipine also suppresses both Ang II- and K+-induced aldosterone secretion, but it blocks the latter at much lower concentrations than the former[2].

In vivo Efonidipine could provide broader beneficial effects including the heart, liver, and plasma, and antioxidant in iron-overload condition in both WT(muβ+⁄+) and HT(muβth-3 ⁄+,) mice[1].


Cell Research:[2]
- Collapse
  • Cell lines: The NCI-H295R human adrenocortical cell line (H295)
  • Concentrations: 0.3 μM and 3 μM
  • Incubation Time: 24 h
  • Method: H295R cells are plated to a density of 0.2 × 106 in 6-well plates and incubated for 48 hours, after which the medium is replaced with low-serum medium containing 0.2% UltroserSF, and the cells are then treated with Ang II (100 nmol/L) or KCl (10 mmol/L) with or without the indicated concentration of Ca2+ channel blocker for 24 hours. The cells are then harvested, and the total cellular RNA is extracted using the isothiocyanate-acid phenol chloroform method. After quantifying the extracted RNA based on absorbance at 260 nm, 500-ng aliquots are reverse transcribed.

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 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 )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / 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.
