Information Tapinarof Tapinarof (GSK2894512, Benvitimod, WBI 1001, DHPS, DMVT 505) is a natural agonist of aryl hydrocarbon receptor (AhR) and induces nuclear translocation of AhR in immortalized keratinocytes (HaCaT) with EC50 of 0.16 nM. Tapinarof induces cellular apoptosis in CD4+ T cells in a dosedependent manner with IC50 of 5.2 μM. Targets AhR (in immortalized keratinocytes); apoptosis (in CD4+ T cells) 0.16 nM(EC50); 5.2 μM In vitro Tapinarof binds and activates AhR in multiple cell types, including cells of the target tissue –human skin. In addition, tapinarof moderates proinflammatory cytokine expression in stimulated peripheral blood CD4+ T cells and ex vivo human skin, and impacts barrier gene expression in primary human keratinocytes; both of these processes are likely to be downstream of AhR activation based on current evidence. In vivo The anti-inflammatory properties of tapinarof derive from AhR agonism is conclusively demonstrated using the mouse model of imiquimod-induced psoriasiform skin lesions. Topical treatment of AhR-sufficient mice with tapinarof leads to compound-driven reductions in erythema, epidermal thickening and tissue cytokine levels. In contrast, tapinarof has no impact on imiquimod-induced skin inflammation in AhR-deficient mice.
