生物活性:
GW3965 is a potent, selective liver X receptor (LXR) agonist with EC50s of 190 nM and 30 nM for hLXRα and hLXRβ, respectively.

体内研究:
GW3965 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 treatment induces an increase of dihydroprogesterone in the spinal cord of diabetic animals in association with an increase of myelin basic protein expression. GW3965 (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. GW3965 (2 mg/kg, i.v.) increases bleeding time and modulated platelet thrombus formation in vivo.

体外研究:
GW3965 promotes GBM cell death?in vitro?with enhanced efficacy in EGFRvIII-expressing tumor cells. GW3965 up-regulates expression of the cholesterol transporter gene ABCA1 and the E3 ubiquitin ligase IDOL and reduces LDLR levels. LXR ligands inhibits platelet aggregation and calcium mobilization stimulated by collagen or CRP. GW3965 (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 (10 μM) or T0901317 (40 μM), the levels of fibrinogen and P-selectin on the platelet surface are reduced.
