  • Acitretin does not induce HIV reactivation in J-lat and ACH-2 cells. (a, b) HIV reactivation induced by acid retinoic (AR) derivative acitretin (25 – 1 μM) in J-Lat cells clone 8.4 (a) and 9.2(b). HDAC inhibitors (HDCAi) panobinostat (PNB, 0.16μM) and vorinostat (VOR, 4 – 0.16 μM) were used as controls. Reactivation was determined by the quantification of GFP+ cells (%) after culturing J-Lat with HDACi and acitretin for 24h. (c, d) HIV reactivation induced by acitretin and HDACi in ACH-2 cells. Reactivation was determined after 48h of incubation by quantification of CAp24 (c) and HIV RNA copy number (d) in the supernatant. Values represent mean±SD of at least three independent experiments performed in triplicate. UN, untreated. *P < 0.05; **P < 0.01; ***P < 0.001.

    Expression of STAT1, pSTAT1, STAT3, pSTAT1, SOCS1 and SOCS3 protein in HaCaT cells of eight groups. HaCaT cells were treated with STAT1-siRNA or STAT3-siRNA (50 nM) in presence or absence of acitretin (5 μM).

Biological Activity

Description Acitretin (Etretin, RO 10-1670) is a second generation retinoid used for psoriasis.
In vitro

Acitretin stimulates ADAM10 promoter activity with an EC(50) of 1.5 mM and leads to an increase of mature ADAM10 protein that results in a two- to three-fold increase of the ratio between alpha- and beta-secretase activity in neuroblastoma cells. [1] Acitretin (5-20 μM) impairs mitochondrial phosphorylation efficiency as demonstrated by the decrease in the state 3 respiration and ATP levels, and by the increase in the lag phase of ADP phosphorylation cycle, without affecting the membrane potential. Acitretin induces Ca(2+)-mediated mitochondrial permeability transition (MPT) and decreased the adenine nucleotide translocase (ANT) content. [2] Acitretin preferentially inhibits the growth of SCL-1 cells in a dose- and time-dependent manner, but not of non-malignant keratinocyte HaCaT cells. Acitretin increases the levels of CD95 (Fas), CD95-ligand and Fas-associated death domain. Acitretin is able to induce apoptosis in skin cancer cells possibly via death receptor CD95 apoptosis pathway without affecting the viability of normal keratinocyte. [3]

In vivo Acitretin undergoes alpha-oxidation, chain shortening O-demethylation, and glucuronidation in the perfused rat liver. [4] Acitretin rapidly appears in liver and muscle of rats, where it undergoes redistribution into skin and adipose tissue. [5]

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.
