Description: | Atpenin A5 is a potent and highly specific complex II inhibitor (IC50 ~10 nM), and is an effective mKATP channel agonist and cardioprotective agent[1]. |
In Vivo: | Atpenin A5 is a potent inhibitor of succinate dehydrogenase (SDH). Succinate dehydrogenase inhibition by Atpenin A5 promotes cardiomyocyte mitosis and regeneration in the postnatal heart after myocardial infarction (MI). Atpenin A5-injected mice demonstrated myocardial thickness at the infarct zone and a significant reduction in scar size compared with controls[2]. Animal Model: Neonatal mice[2] Dosage: 100 μg/kg Administration: Injected daily Result: Demonstrated myocardial thickness at the infarct zone and a significant reduction in scar size compared with controls. |
In Vitro: | Atpenin A5 shows the inhibition profile for submitochondrial particles (SMPs), mitochondria, and cardiomyocytes, with IC50 values of 8.3, 9.3, and 8.5 nM, respectively. Atpenin A5 (AA5) is a potent and specific complex II inhibitor. Atpenin A5 (1 nM) also activates the mKATP channel and protects against simulated ischemia-reperfusion (IR) injury in isolated cardiomyocytes[1]. |
