A novel series of 49 wogonin derivatives were synthesized by introducing group at 7-, 8- or B ring of wogonin. The cytotoxic activities against HepG2, A549 and BCG-823 cancer cell lines were also investigated in vitro. Several of them showed obvious cytotoxic activities and compound 3h possessed the highest potency against HepG2, A549, and BCG-823 with IC50 values of 1.07 μM, 1.74 μM and 0.98 μM, respectively. A quantitative structure-activity relationship (QSAR) study of these synthetic derivatives as well as wogonin indicated that high solubility and low octanol/water partition coefficient are favorable, and excessive electrostatic properties and refractivity are unfavorable for the cytotoxic activities of these wogonin derivatives. These findings and results provide a base for further investigations.

Natural (-)-Celosine was isolated as a novel endocyclicditerpene with an unprecedented skeleton from Celosia cristata L. Its structure was established by comprehensive 1D and 2D NMR spectroscopic analysis in combination with single-crystal X-ray crystallographic diffraction of synthesized (+)-Celosine. (-)-Celosine was expected to have an anti-atherosclerotic activity in vivo, and myeloperoxidase (MPO) expression may be the mechanism underlying this anti-atherosclerotic activity.
