Description：Lasofoxifene (CP-336156) is an orally active and selective estrogen receptor modulator (SERM). Lasofoxifene exhibits an anti-osteoporotic function and also inhibits primary tumor growth and metastases. Lasofoxifene can be used for research of breast cancer and postmenopausal osteoporosis.

In Vitro：Lasofoxifene (1 nM-1 μM; 48 h) shows antagonist activity on ER+ breast cancer cells without being affected by the expression level of activating ERα mutants relative to wild-type (WT) ERα[2].

In Vivo：Lasofoxifene (4 mg/mice; s.c.; 5 day/week; for 43 d) decreases arthritis severity, by reducing cartilage oligomeric matrix protein (COMP), the serum marker of cartilage destruction and reducing serum IL-6 (inflammatory cytokine) levels in mice[1]. Lasofoxifene (4 mg/mice; s.c.; 5 day/week; for 43 d) protects against generalised bone loss in CIA by increasing trabecular bone mineral density (BMD), cortical thickness in mice[1]. Lasofoxifene (5, and 10 mg/kg; s.c.; 5 day/week; for 70 d) exerts function of inhibiting primary tumor growth and reducing metastases to the lung and the liver in mice[3].

IC50 & Target：Target: Estrogen Receptor[1] In Vitro Lasofoxifene (1 nM-1 μM; 48 h) shows antagonist activity on ER+ breast cancer cells without being affected by the expression level of activating ERα mutants relative to wild-type (WT) ERα[2].
