In vitro: Previous study indicated that necrostatin-1 was a selective allosteric inhibitor of the death domain receptor–associated adaptor kinase RIP1 in vitro. In this study, RIP1 was found to be the primary cellular target responsible for the antinecroptosis activity of necrostatin-1. In addition, two other necrostatins, necrostatin-3 and necrostatin-5, were also shown to target the RIP1 kinase step in the necroptosis pathway, but through different mechanism compared with that of necrostatin-1. The findings established necrostatins as the first-in-class inhibitors of RIP1 kinase, the key upstream kinase involved in the activation of necroptosis. In vivo: A previous study was designed to investigate the protective effects and mechanisms of Nec-1 in concanavalin A-induced hepatitis in mice. It was found that in Nec-1-treated mice the amelioration in liver functions and histopathological changes and the suppression of inflammatory cytokine production were observed. Western blotting analyses showed that the expression of TNF-α, IFN-γ, IL2, IL6, and RIP1 was significantly reduced in the Nec-1-treated mice, which was further confirmed by immunofluorescence and immunohistochemistry. In addition, autophagosome formation was significantly reduced by Nec-1 treatment. These results indicated that Nec-1 could prevent concanavalin A -induced liver injury via RIP1-related and autophagy-related pathways.

例如，已知某工具药用于小鼠的剂量为88 mg/kg , 则用于大鼠的剂量换算方法：将88 mg/kg 乘以小鼠的Km系数（3），再除以大鼠的Km系数（6），得到该药物用于大鼠的等效剂量44 mg/kg。
