Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

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] This compound (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. It induces Ca(2+)-mediated mitochondrial permeability transition (MPT) and decreased the adenine nucleotide translocase (ANT) content. [2] The chemical preferentially inhibits the growth of SCL-1 cells in a dose- and time-dependent manner, but not of non-malignant keratinocyte HaCaT cells. It increases the levels of CD95 (Fas), CD95-ligand and Fas-associated death domain. It 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] This compound rapidly appears in liver and muscle of rats, where it undergoes redistribution into skin and adipose tissue. [5]
