RANKL-IN-2
RANKL-IN-2 is an orally active RANKL inhibitor with Kd values of 3.21 μM and 4.625 μM in the SPR and MST assays, respectively. RANKL-IN-2 binds to RANKL to interfere with RANKL-RANK interaction. RANKL-IN-2 suppresses osteoclastogenesis by inhibiting ROS, MAPK and NF-κB pathways. RANKL-IN-2 inhibits osteoclastogenesis via inhibition of RANKL-induced osteoclast formation, bone resorption, and osteoclast-specific gene and protein expressions in vitro.RANKL-IN-2 prevents bone loss in ovariectomized osteoporosis mice.RANKL-IN-2 can be used for the research of osteoporosis.

Biological Activity
RANKL-IN-2 (compound 3w) (1 μM; 4 days) inhibits RANKL-induced osteoclastogenesis in RAW 264.7 cells with potent activity at 1 μM[1].
RANKL-IN-2 (0.0625-2 μM; 5 days) inhibits RANKL-induced osteoclastogenesis in BMMs dose-dependently with an IC50 of 0.577 μM[1].
RANKL-IN-2 (0.5-2 μM; 7 days) suppresses RANKL-induced F-actin ring formation and bone resorptionin by BMMs in a dose-dependent manner[1].
RANKL-IN-2 (0.5-2 μM; 5 days) inhibits RANKL-induced expression of osteoclast marker genes and proteins in BMMs dose-dependently[1].
RANKL-IN-2 (0.5-2 μM; 5 days) regulates ROS signaling in BMMs by inhibiting ROS production and promoting antioxidant enzyme expression[1].
RANKL-IN-2 (0.5-2 μM; 48 h) suppresses RANKL-induced intracellular and mitochondrial ROS production in BMMs dose-dependently[1].
RANKL-IN-2 (1 μM; 6 h pretreatment, 0-60 min RANKL stimulation) inhibits RANKL-induced MAPK and NF-κB signaling pathways in BMMs at 1 μM[1].
RANKL-IN-2 (0.5-2 μM; 7 or 21 days) does not affect osteoblast differentiation or mineralization in MC3T3-E1 cells[1].
RANKL-IN-2 is stable in PBS and rat plasma for at least 12 h[1].

Animal Model:C57BL/6 (female, 7 weeks old, ovariectomy-induced)[1]
-
Dosage:10 mg/kg
-
Administration:p.o.; every other day; 8 weeks
-
Result:Significantly increased bone volume/total bone volume (BV/TV), trabecular thickness (Tb.Th), and trabecular number (Tb.N) in OVX mice; reduced trabecular separation (Tb.Sp); reversed the decrease in bone surface (BS) caused by OVX; significantly decreased the number of TRAP-positive cells around the trabecula; suppressed osteoclast formation in vivo.
