Abstract: We have introduced a sensitive method for studying oxygen/glucose deprivation (OGD)-induced mitochondrial alterations in homogenates of organotypic hippocampal slice cultures (slices) by high-resolution respirometry. Using this approach, we tested the neuroprotective potential of the novel non-immunosuppressive cyclosporin (CsA) derivative Cs9 in comparison with CsA, the immunosuppressive CsA analogue [D-Ser](8)CsA, and MK 801, a N-methyl-D-aspartate (NMDA) receptor antagonist. OGD/reperfusion reduced the glutamate/malate dependent (and protein-related) state 3 respiration to 30% of its value under control conditions. All of the above drugs reversed this effect, with an increase to >88% of the value for control slices not exposed to OGD. We conclude that Cs9, [D-Ser](8)CsA, and MK 801, despite their different modes of action, protect mitochondria from OGD-induced damage. • Keywords: cyclosporin (CsA) derivative Cs9, CsA analogue [D-Ser](8)CsA, NMDA-receptor antagonist, neuroprotection
