EB 1089 is a synthetic vitamin D analog that is 50-200 times more potent than calcitriol at inhibiting cell proliferation and differentiation, yet displays reduced calcemic activity compared to that of calcitriol. It has been shown to promote tumor regression in vitro by inducing apoptosis.

EB 1089 is an analogue of Calcitriol (C144500), which is a biologically active form of Vitamin D3 (1). It can be used in androgen receptor-targeted therapy research for breast cancer (2). EB 1089 exhibits anti-cancer properties.
