Tolerability of H₂S donors. b.End3 cells were treated with mitochondrial and non-mitochondrial H₂S donor compounds for 24 h. A: The cellular viability was measured by the MTT assay. B: LDH release was detected by measuring the LDH activity in the cell culture supernatant. The non-mitochondrial H₂S donors are better tolerated by the cells: the mitochondrial H₂S donors reduce the cell survival at lower concentrations.
