How to use

In Vitro:

Thalidomide may exert anti-angiogenic effect in isolated blood vessels and endothelial cells. Thalidomide-OH is a putative hydroxylated thalidomide metabolite. Thalidomide-OH has weak anti-angiogenic activity (14% mean inhibition of blood vessel density at 100 mg). Thalidomide-OH does not have any anti-proliferative effect against the breast or neuroblastoma cells, but do possess appreciable anti-proliferative activity against the endothelial cells.
