In this study, we used an MTT assay to investigate the inhibitory activity of biflavonoids 1-22 against Aβ42 cytotoxicity in PC-12 cell cultures. Cytoprotective effects were observed for the following amentoflavone type biflavonoids: podocarpusflavone B 8, isoginkgetin 10, sciadopitysin 13, and kayaflavone 15. These biflavonoids exhibited strong activity in tested compounds, with EC50 values of 5.18, 10.77, 9.84, and 5.29 μM, respectively. Cell viability tests of PC-12 cells revealed that biflavonoids 13 and 15 had stronger inhibitory activities than apigenin 23 and (-)-epigallocatechin gallate 24.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Amyloid beta-Peptides,Animals,Biflavonoids,Cell Survival,PC12 Cells,Peptide Fragments,Protective Agents,Rats,Structure-Activity Relationship[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Alzheimer’s disease,Amentoflavone,Amyloid-β,Biflavonoids,PC-12 cells[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1016/j.bmcl.2015.04.106[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
