Sophoflavescenol 是异戊烯基黄酮类化合物，能够抑制PDE5的活性，IC50=0.013 μM。它也抑制 RLAR，HRAR，BACE1，AChE 和 BChE，IC50值分别为 0.30 μM，0.17 μM，10.98 μM，8.37 μM 和 8.21 μM。

Sophoflavescenol is a mixed inhibitor of PDE5 with a K(i) value of 0.005 microM. Sophoflavescenol has antioxidant, anti-inflammatory, and apoptotic effects , these effects might contribute to the antitumor activity without severe side effects. Sophoflavescenol exerts notable anti-inflammatory activity by inhibiting nitric oxide generation and tert-butylhydroperoxide-induced ROS generation rather than inhibiting nuclear factor kappa B activation in RAW 264.7 cells.

Despite the small effect on human breast adenocarcinoma (MCF-7), Sophoflavescenol showed cytotoxicity against human leukaemia (HL-60), Lewis lung carcinoma (LLC), and human lung adenocarcinoma epithelial (A549) cells. Interestingly, it also exerted potent in vivo antitumor activity by tumor growth inhibition in the LLC tumor model as well as apoptotic activity by caspase-3 activation in HL-60 cells. In addition, it exhibited potent antioxidant activities in 1,1-diphenyl-2-picrylhydrazyl, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt radicals and lipid peroxidation assays. Sophoflavescenol exerted notable anti-inflammatory activity by inhibiting nitric oxide generation and tert-butylhydroperoxide-induced ROS generation rather than inhibiting nuclear factor kappa B activation in RAW 264.7 cells[1]
