EB 1089 is a vitamin D receptor (VDR) agonist; analog of calcitriol (Cat. No. 2551). Exhibits anti-tumor and anti-proliferative activity with reduced hypercalcemic effects. 60 times more potent in inhibiting MCF-7 cell growth in vitro; also shown to induce autophagy in MCF-7 cells. Reverses the effects of parathyroid hormone-related protein (PTHrP).
