Recent cardiology research studies have reported the role, function, and structure of the mitochondrial permeability transition pore (mPTP) and have shown that its opening plays a key role in the progression of myocardial cell death secondary to reperfusion. In this manuscript, we validated a new pharmacological approach as an adjunct to reperfusion in myocardial infarction (MI) treatment and describe the discovery, optimization, and structure-activity relationship (SAR) studies of the first small-molecule mPTP opening inhibitors based on a 1,3,8-triazaspiro[4.5]decane scaffold that targets the c subunit of the F1/FO-ATP synthase complex. We identified three potential compounds with good mPTP inhibitory activity and beneficial effects in a model of MI, including a decreased apoptotic rate in the whole heart and overall improvement of cardiac function upon administration during reperfusion. The selected compounds did not show off-target effects at the cellular and mitochondrial levels. Moreover, the compounds preserved the mitochondrial ATP content despite interacting with the ATP synthase complex.
