Mechanism of Action

Targets/IC₅₀/Ki	HDAC4
In vitro	Tasquinimod inhibits tumor angiogenesis by allosteric inhibition of HDAC4/N-CoR/HDAC3 dependent deacetylation of HIF-1α. This compound 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.
In vivo	This compound (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.
