The molecular modeling study was performed by docking andrographolide to COX-2 enzyme at the site where SC-558, a selective inhibitor of this enzyme, was co-crystallized and compared its interaction to the enzyme with SC-558’s. The inhibition of COX-2 expression was determined by measuring PGE2 production in human fibroblast cells stimulated with LPS with and without andrographolide preincubations. Andrographolide interacted with Arg513 and His90 in the cyclooxygenase site of COX-2 and inhibited PGE2 production in human fibroblast cells (IC50 = 4 uM). These data confirm that andrographolide’s anti-inflammatory activity occurs via inhibition of COX-2 expression. © 2010 Asian Network for Scientific Information.[/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]Andrographolide,Cyclooxygenases,Human fibroblast cells,Molecular modeling studies,Prostaglandin[/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]Andrographolide,Cyclooxygenase enzyme,Human fibroblast cells,Molecular modeling study,Prostaglandin[/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/10.3923/jas.2010.1481.1484[/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]
