  • (h and i) Triptolide inhibits transcription. After exposure to triptolide (1 μm), spironolactone (10 μm), actinomycin D (2 μm, transcription inhibitor used as a positive control) or DMSO for 6 h, the global RNA synthesis was evaluated by the measurement of 5-EU incorporation. The figure shows representative merged pictures of DAPI and 5-EU signal. The intensity of the signal was evaluated through fluorescence microscopy (h) and quantified with the CellProfiler Software. Triptolide but not spironolactone inhibits global transcription.

    (A, B) Indicated HIV-1 latency cells (A. J-LAT 10.6; B. CA5) were treated with levosimendan or spironolactone (5, 10, or 20 μM) in combination with TNFα (10 ng/ml). After 24 hr, mRNA was extracted, and reverse transcribed to cDNA for measurement of HIV-1 initiated or elongated (proximal [Pro], intermediate [Int], and distal [Dis]) transcripts by qPCR. Results were normalized to DMSO control. Values represent the mean ± s.d. (n = 4-6).

Biological Activity

Description Spironolactone is a potent antagonist of the androgen receptor with IC50 of 77 nM.
Targets
Androgen Receptor [1]
77 nM
In vitro

Spironolactone is a strong AR antagonist (IC50 ~ 77 nM), a weak GR antagonist (IC50 ~ 2.4 μM), and a weak PR agonist (EC50 ~ 740 nM). [1] Spironolactone inhibits androstanolone binding in rat prostate nuclei and androstanolone specific binding in rat prostate cytosol. [2]

In vivo Spironolactone (1 mg/day) exerts anti-androgenic activity in rats. A single pretreatment of spironolactone (1 mg/rat) inhibits specific and saturable uptake of hormone into prostate induced by tracer dose administration of [3H]testosterone. [2]

Protocol

Solubility (25°C)

In vitro DMSO 83 mg/mL (199.24 mM)
Ethanol 20 mg/mL (48.01 mM)
Water 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.

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.
