产品描述

Lasofoxifene (tartrate) is a third-generation, nonsteroidal selective estrogen receptor modulator (SERM).

Estrogen receptors are activated by the hormone estrogen (17β-estradiol). SERMs are characterized by having estrogen agonist action in some tissues while acting as estrogen antagonists in others [1][2].

Lasofoxifene, also known as CP 336,156, is a third-generation, nonsteroidal selective estrogen receptor modulator. Lasofoxifene bound with high affinity to the human estrogen receptor-α with IC50 value of 1.5 nM [1]. Lasofoxifene is also a CB2 inverse agonist [4].

In aged female rats, Lasofoxifene decreased total serum cholesterol and fat body mass, and no uterine hypertrophy was observed. In 5-month-old ovariectomized (OVX) Sprague-Dawley female rats, Lasofoxifene completely prevented OVX-induced increases in body weight gain, total serum cholesterol, and serum osteocalcin. CP-336,156 completely prevented OVX-induced bone loss and inhibited the increased bone turnover associated with estrogen deficiency in lumbar vertebrae, proximal tibiae, and distal femora [1].

In postmenopausal women with osteoporosis, lasofoxifene reduced risks of nonvertebral and vertebral fractures, ER-positive breast cancer, coronary heart disease, and stroke but an increased risk of venous thromboembolic events [2][3].
