 Use of Amentoflavone-4',4",7-trimethyl Ether


Sciadopitysin is a type of biflavonoids in leaves from ginkgo biloba[1]. Sciadopitysi inhibits RANKL-induced osteoclastogenesis and bone loss by inhibiting NF-κB activation and reducing the expression of c-Fos and NFATc1[2].

Description Sciadopitysin is a type of biflavonoids in leaves from ginkgo biloba[1]. Sciadopitysi inhibits RANKL-induced osteoclastogenesis and bone loss by inhibiting NF-κB activation and reducing the expression of c-Fos and NFATc1[2].

Target

NF-κB

In Vitro Sciadopitysin (2.5, 5, 10 μM ) strongly reduces RANKL-induced osteoclast-specific genes expression, including cathepsin K (CTSK), tartrate-resistant acid phosphatase (TRAP) and MMP-9. Furthermore, Sciadopitysin apparently attenuates RANKL-increased expressions of c-Fos and NFATc1[2].
In Vivo Sciadopitysin (i.p.; 10 mg/kg; every other day for 8 days) can reverse the bone loss in LPS-induced mice model (C57BL/6 mice; 6 weeks old)[2].
