Biological Activity: Cypyrafluone (Huanbifucaotong) is a HPPD inhibitor and herbicide with an IC50 of 0.70 µM against AtHPPD. Cypyrafluone blocks the biosynthesis of plastoquinone and α-tocopherol through targeted inhibition of HPPD enzyme activity, thereby leading to the loss of photosynthetic pigments and triggering ROS-mediated photooxidative damage. Cypyrafluone can be used in research on agricultural herbicides[1][2][3][4].
