GW3965 hydrochloride
GW3965 hydrochloride 是肝 X 受體 (LXR) 激動劑，對 hLXRα 和 hLXRβ 的 EC50 分別為 190 nM 和 30 nM。
生物活性
GW3965 hydrochloride is a potent and selective liver X receptor (LXR) agonist with EC50s of 190 nM and 30 nM for hLXRα and hLXRβ, respectively[1][2][3].
IC50 & Target
EC50: 190 nM (hLXRα), 30 nM (hLXRβ)[4]
體外研究(In Vitro)
GW3965 hydrochloride promotes GBM cell death in vitro with enhanced efficacy in EGFRvIII-expressing tumor cells. GW3965 hydrochloride up-regulates expression of the cholesterol transporter gene ABCA1 and the E3 ubiquitin ligase IDOL and reduces LDLR levels[2]. LXR ligands inhibits platelet aggregation and calcium mobilization stimulated by collagen or CRP. GW3965 hydrochloride (1 or 5 μM) displays a minor inhibitory effect on fibrinogen binding and P-selectin exposure, when platelets are stimulated with 1 μg/mL CRP. But using higher concentrations of GW3965 hydrochloride (10 μM) or T0901317 (40 μM), the levels of fibrinogen and P-selectin on the platelet surface are reduced[3].
體內研究(In Vivo)
GW3965 hydrochloride induces an increase of neuroactive steroids in the spinal cord, the cerebellum and the cerebral cortex of STZ-rats, but not in the CNS of non-pathological animals. GW3965 hydrochloride treatment induces an increase of dihydroprogesterone in the spinal cord of diabetic animals in association with an increase of myelin basic protein expression[1]. GW3965 hydrochloride (40 mg/kg, p.o.) strongly induces ABCA1 expression and reduces LDLR expression, and this is accompanied by 59% inhibition of tumor growth, and a 25-fold increase in GBM cell apoptosis in vivo[2]. GW3965 hydrochloride (2 mg/kg, i.v.) increases bleeding time and modulated platelet thrombus formation in vivo[3].
