Ischemia/reperfusion injury (IRI) is a condition that occurs when tissues from different organs undergo reperfusion following an ischemic event. The mitochondrial permeability transition pore (mPTP), a multiprotein platform including structural components of ATP synthase with putative gate function, is an emerging pharmacological target that could be modulated to facilitate the restoration of organ function after a hypoxic insult.

Abstract
Ischemia/reperfusion injury (IRI) is a condition that occurs when tissues from different organs undergo reperfusion following an ischemic event. The mitochondrial permeability transition pore (mPTP), a multiprotein platform including structural components of ATP synthase with putative gate function, is an emerging pharmacological target that could be modulated to facilitate the restoration of organ function after a hypoxic insult. Herein, we reported the synthesis and biological characterization of new molecules with a 1,4,8-triaza-spiro[4.5]decan-2-one framework of potential interest for the treatment of IRI able to inhibit the opening of mPTP in a cardiac model in vitro. Modelling studies were useful to rationalise the observed structure-activity relationship detecting a binding site for the investigated molecules at the interface between the c8-ring and subunit a of ATP synthase. Compound 14e was shown to display high potency as mPTP inhibitor combined with the capability to counteract cardiomyocytes death in an in vitro model of hypoxia/reoxygenation.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
