Abstract
Two new compounds, aphegiractin A1/A2 (1a/1b), and seven known compounds were isolated by phytochemical work on EtOAc-soluble ingredients extracted from stem and root barks of Daphne giraldii. Their structures were established based on extensive spectroscopic methods, including HRESIMS, CD experiments, 1D and 2D NMR. All compounds were evaluated for their antioxidant activity to DPPH, ABTS radical scavenging activity and inhibitory activity on tyrosinase. Of these compounds, compound 3 exhibited significant antioxidant activities.

Abstract
We report here the orchestration of molecular ion networking (MoIN) and a set of computational and informatics assisted structural elucidation approaches in the discovery of 23 new prenyl-flavonoids and 13 known molecules from Daphne giraldii Nitsche (Thymelaeaceae), some of which possess significant bioactivity against hepatoma carcinoma. Daphnegiratriprenylone A (DPTP-A) represents the class of polyprenyl-flavonoids possessing a triprenyl substitution, and was identified with the guidance of mass spectrometry and nuclear magnetic resonance combined with computational approaches. This approach illustrates a paradigm shift in the application of computational tools for the direct assignment of new natural product structures and it was demonstrated to be reliable compared to conventional 2D-NMR techniques. Seventeen compounds exhibited potent and selective activity against Hep3B cells (IC50 ranging from 0.42 to 7.08 μM). Tyrosine kinase FGFR1 has emerged as a potential target of polyprenyl-flavonoids by a reverse pharmacophore mapping approach. We validated that the prenyl-flavonoids effectively inhibit FGFR1 using the Mobility Shift Assay, Western blot and molecular dynamics simulations, and the results suggest significant potency of the compounds towards FGFR1. These findings provide a new chemical class with strong links to traditional medicines, possessing reasonable safety for developing potential therapeutic agents for FGFR1-related diseases.

Abstract
Daphne giraldii Nitsche, belongs to Daphne genus, has been reported to exert anti-tumor activities. Our previous study suggested that flavones from Daphne giraldii have significant inhibitory effects on hepatocellular carcinoma (HCC) cells. However, the potential target of this type flavone was still unknown. In this study, 74 flavonoids compounds of Daphne giraldii and 41 potential targets of HCC were analyzed by the network, the most potential target was histone deacetylase 6 (HDAC6). Considering the cytotoxicity, compound 70 (Daphnegiravone D, DGD) was chosen for further confirmation. Molecular docking study revealed that DGD formed high binding affinity with HDAC6. Concomitantly, pharmacological studies indicated that DGD could inhibit the expression of HDAC6 in vitro and in vivo. In this study, network pharmacology along with experimental validation predicted and verified HDAC6 as one of potential targets of flavones, these investigations provide a new insight for further study of Daphne giraldii on HCC treatment.

Abstract
Daphne giraldii Nitsche. (Thymelaeaceae) is a slow-growing shrub which has been used in Chinese folk medicine and commonly called ‘Zu Shima’. In this study, we assembled the complete chloroplast (cp) genome of D. giraldii using data from high-throughput Illumina sequencing. The D. giraldii cp genome is 171,643 bp in size and includes two inverted repeat regions of 41,798 bp each, which is separated by a large single copy region of 85,171 bp and a small single copy region of 2876 bp. A total of 137 genes were predicted, including 38 tRNA, 8 rRNA, and 90 protein-coding genes. In addition, 10 PCG genes possess a single intron, 92 PCG genes no intron, 1 gene harbor two introns. Six tRNA genes harbor a single intron. Phylogenetic analysis indicated that D. giraldii is closer to Daphne kiusiana and Daphne tangutica than other taxa.
