Biological Activity

Description Tasquinimod (ABR-215050) is an orally active antiangiogenic agent by allosterically inhibiting HDAC4 signalling. Phase 3.
HDAC4 [1]
In vitro

Tasquinimod inhibits tumor angiogenesis by allosteric inhibition of HDAC4/N-CoR/HDAC3 dependent deacetylation of HIF-1α. [1] Tasquinimod also targets infiltrating myeloid cells, and modulates local tumour immunity by blocking the interaction between S100A9 and its ligands receptor of advanced glycation end products and Toll-like receptor 4. [3]

In vivo Tasquinimod (30 mg/kg/d p.o.) shows anti-angiogenic activity and thus causes tumor growth inhibition in mice bearing human and rodent prostate cancer models. [2]

Protocol (from reference)

Animal Research:


  • Animal Models: Mice bearing PC-82 , CWR-22Rv1, LAPC-4, or LNCaP prostate cancer xenografts.
  • Dosages: ~30 mg/kg/d
  • Administration: p.o.

Solubility (25°C)

In vitro

In vivo

Add solvents to the product individually and in order
(Data is from Selleck tests instead of citations):
5% DMSO+30% PEG 300+ddH2O
For best results, use promptly after mixing.

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.
