Kinase experiment [1]: | |
Preparation Method |
Cells were lysed, Immunoprecipitation was carried out for 16 h at 4 °C using anti-FLAG M2 agarose beads, Beads were incubated in 15 ul of the reaction buffer for 15 min at 23-25 °C in the presence of different concentrations of necrostatins (including Necrostatin-1). Kinase reaction was initiated by addition of 10 μM cold ATP and 1 μCi of [y-32P]ATP, and reactions were carried out for 30 min at 30°C. |
Reaction Conditions |
RIP1 kinase assay( Necrostatin-1) was performed at 30°C for 30 min |
Applications |
Necrostatin-1 is a RIP1 kinase inhibitor, RIP1 is the primary cellular target responsible for the antinecroptosis activity of necrostatin-1. |
Cell experiment [2]: | |
Cell lines |
Cardiomyocyte progenitor cells (CMPCs) |
Preparation Method |
CMPCs were pretreated with vehicle or Necrostatin-1 for 30 min prior to the addition of tert-Butyl hydroperoxide in serum-free M199 medium. |
Reaction Conditions |
30 µM Necrostatin-1 for 30 min |
Applications |
Under oxidative stress conditions, CMPC mainly displayed a necrotic phenotype and by pretreatment with Necrostatin-1, we observed a 37 ± 8% reduction in necrotic cell death in CMPCs compared with vehicle. Not find differences in apoptotic-mediated cell death. Therefore, Necrostatin-1 increased the survival of CMPCs by inhibiting necrotic cell death. |
Animal experiment [3]: | |
Animal models |
Eight-week-old male C57Bl/6 mice |
Preparation Method |
Mice undergo sham surgery or bilateral renal pedicle clamping 24 hours before intraperitoneal injection of either PBS, the highly specific RIP1 kinase inhibitor Necrostatin-1, or the inactive derivate of necrostatin-1 (Necrostatin-1i) in the presence or absence of RCM. |
Dosage form |
Necrostatin-1 (1.65 mg/kg body weight) was applied intraperitoneally 15 min before RCM-injection. |
Applications |
CIAKI Is Attenuated by Necrostatin-1, an Inhibitor of the Kinase Domain of Receptor-Interacting Protein Kinase-1. |

Necrostatin-1は、細胞内で主にRIP1に作用します[5]。IC50値が0.32 mMのRIP1キナーゼ阻害剤であり、効果的にRIP1オートフォスホリレーションを抑制し、RIP1-RIP3-MLKLシグナル伝達を阻害することができます[7]。また、Necrostatin-1はIDO阻害剤でもあります[2]。
酸化ストレス条件下では、CMPCは主に壊死的フェノタイプを示し、Necrostatin-1の前処理により、車両と比較して37±8%の壊死細胞死が減少したことが観察されました。アポトーシス媒介性細胞死に差異は見られませんでした。したがって、Necrostatin-1は壊死的細胞死を抑制することにより、CMPCの生存率を増加させました[4]。CoCl2処理後、アポトーシスおよび壊死C2C12細胞の比率が増加し、TEMで典型的なネクロプトーシス形態学的特徴が観察されました。一方でNecrostatin-1はCoCl2誘導性酸化ストレスに対して保護効果を示しました。Necrostatin-1投与はRIP1、p ERK1/2、HIF 1α、BNIP3およびROSレベルを有意に低下させると同時にC2C12分化を促進しました。またNecrostatin-1はCoCl2誘導性ミトコンドリア膜電位低下を逆転させました[6]。
マウスにおいて、レセプター相互作用性タンパク質1(RIP1)キナーゼドメインの特異的阻害剤であるネクロスタチン-1(Nec-1)は、浸透圧性腎症とCIAKIを防止しました。一方、非活性なネクロスタチン-1誘導体(Nec-1i)やパンカスパーゼ阻害剤zVADでは効果がありませんでした。また、Necrostatin-1は周管間拡張を抑制することにより微小血管の血液動態の調節及びCIAKIの病態生理学に関連する新たな役割があることが示唆されました[3]。
