atpenin A5 Chemische Eigenschaften,Einsatz,Produktion Methoden

Beschreibung

Enantioselective total synthesis of atpenin A5, a potent mitochondrial complex II (succinate-ubiquinone oxidoreductase) inhibitor, has been achieved by a convergent approach through a coupling reaction between 5-iodo-2,3,4,6-tetraalkoxypyridine and a side-chain aldehyde. The two key segments were synthesized through ortho-metalation/boronation with (MeO)3B/oxidation with mCPBA, ortho-iodination, halogen dance reaction, Sharpless epoxidation and regioselective epoxide-opening reaction.

Definition

Atpenin A5 belongs to a class of antifungal antibiotics isolated from Penicillium sp. The atpenins are effective against filamentous fungi, particularly Trichophyton sp., and are specific and potent inhibitors of the succinate-ubiquinone reducatase activity of the mitochondrial complex II. Atpenin A5 is the most effective inhibitor against complex II from all the atpenins and has been shown to protect against cardiac-reperfusion injury in rat studies through the stimulation of mitochondrial KATP channels. Atpenin A5 is an inhibitor of SDHB, SDHC and SDHD.

Biologische Aktivit?t

Mitochondrial complex II (succinate dehydrogenase or succinate:ubiquinone oxidoreductase) is a functional member of the Krebs cycle and the aerobic respiratory chain that couples the oxidation of succinate to fumarate with the reduction of quinone to quinol. Atpenin A5, an antifungal antibiotic isolated from Penicillium sp. found in soil, is a highly specific ubiquinone-binding site inhibitor of succinate dehydrogenase (IC50s = 12 and 3.7 nM in nematode and mammalian mitochondria, respectively, versus IC50s > 100 μM for inhibition of complex I and complex III enzymes). Atpenin A5 has cardioprotective effects against simulated ischemia-reperfusion injury in cardiomyocytes. Several mechanisms through which this occurs, including activation of mitochondrial ATP-sensitive potassium channels or modulation of mitochondrial reactive oxygen species generation, have been proposed.
