产品名称
CP-336156 tartrate
产品介绍
Lasofoxifene (CP-336156) tartrate 是一种具有口服活性和选择性的雌激素受体调节剂 (SERM)。Lasofoxifene tartrate 具有抗骨质疏松的功能,还能抑制原生肿瘤生长和转移。Lasofoxifene tartrate 可用于乳腺癌和绝经后骨质疏松症的研究。
生物活性

Lasofoxifene (CP-336156) tartrate is an orally active and selectiveestrogen receptormodulator (SERM)[1]. Lasofoxifene tartrate exhibits an anti-osteoporotic function and also inhibits primary tumor growth and metastases. Lasofoxifene tartrate can be used for the research of breastcancerand postmenopausal osteoporosis[1][2].

IC50& Target

Target: Estrogen Receptor[1]

体外研究
(In Vitro)

Lasofoxifene tartrate (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].

体内研究
(In Vivo)

Lasofoxifene tartrate (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[1].
Lasofoxifene tartrate (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 tartrate (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].

Animal Model:Post-menopausal RA model on OVX (ovariectomised) DBA/1 mice (female DBA/1 mice, 8-10 weeks old, CIA-treated)[1]
Dosage:4 mg/mouse/day
Administration:Subcutaneous injection; 5 days a week from the first signs of arthritis (day 18); 43 days
Result:Reduced in arthritis severity, including synovial inflammation and destruction of joints reduction.
The mean arthritis frequency was 47% while the vehicle group was 81% at 42 days post immunization.
Animal Model:NSG mices with xenograft tumors model (MIND, mammary intraductal): WT, Y537S and D538G ERα render tumors[3]
Dosage:1, 5, or 10 mg/kg
Administration:Subcutaneous injection; 5 days per week; for 70 days
Result:Elicited a superior inhibitory effect at a dose of 10 mg/kg, resulted potential tumor shrinkage in Y537S and D538G tumors.
And also reduced tumor weight to 60% for Y537S and 50% for D538G at 5 and 10 mg/kg, respectively.
