S except picrasidine M have steady H-bonds with two crucial residues
S except picrasidine M have steady H-bonds with two crucial residues Gly202 and Ser243. Picrasidine M andEvidence-Based Complementary and Option Medicine aurantiamide acetate have an H-bond with residue Tyr228. Isopraeroside IV has H-bonds together with the other two residues Asp105 and His248 soon after MD simulation. The occupancies of H-bonds for important residues of PARP-1 protein are listed in Table two, and the fluctuation of distances for H-bonds with frequent residues of PARP-1 protein is shown in Figure 9. The H-bonds occupancies and distances fluctuation over MD simulation displays the steady H-bonds amongst ligands, A927929, isopraeroside IV, aurantiamide acetate, and residues Gly202 and Ser243. Moreover, picrasidine M has steady H-bonds with residue Tyr228. For A927929, although the H-bond occupancy with residue His201 over 40 ns of MD simulation is 58 , the distance variation of Hbond shown in Figure 9 indicates that this H-bond was lost at the finish on the MD simulation. For isopraeroside IV, the Hbonds with residues Asp105 and His248 are tended to stabilize soon after MD simulation. Aurantiamide acetate also has a steady H-bond with residue Tyr228 soon after 25 ns of MD simulation. For picrasidine M, the H-bond with residue Tyr246 inside the docking simulation has shifted to binding with residue Lys242 after MD simulation, and it has one more H-bond with residue Tyr246 beneath dynamic circumstances. The leading TCM compounds, isopraeroside IV and aurantiamide acetate, have steady H-bonds with residues Gly202 and Ser243 as A927929. Additionally, isopraeroside IV also has stable H-bonds with residues Asp105 and His248, which stabilized the docking pose of ligand inside the binding domain. Aurantiamide acetate has yet another steady H-bond with residue Tyr228 comparable to picrasidine M. For picrasidine M, it types the stable H-bond with residue Lys242 as an alternative of residues Gly202 and Ser243.Authors’ ContributionKuan-Chung Chen and Mao-Feng Sun are equally contributed.AcknowledgmentsThe analysis was supported by Grants in the National Science Council of Taiwan (NSC102-2325-B039-001 and NSC102-2221-E-468-027-), Asia LTC4 Biological Activity University (ASIA100-CMU2 and ASIA101-CMU-2, 102-ASIA-07), and China Health-related University Hospital (DMR-103-058, DMR-103-001, and DMR-103-096).
