STING1 and skin cancer: Nitrofuran Derivatives: From a screen to identify inhibitors of STING (a signaling molecule involved in type I interferon production, relevant to the pathogenesis of skin cancers, and previously targeted by 2-BP at 50 μM [203]), C-176 and C-178 were shown to hinder the palmitoylation state of murine STING without altering other targets, including the transferrin receptor or calnexin [204].
