7,8 and organ protection from ischemia/reperfusion injury.
9,10 Newly synthesized transition metal carbonyl-compounds, CO release molecules (CORMs), are effective in regulating CO release in vivo and in vitro in appropriate circumstances.
11 These CO releasing molecules can therefore be used as the new carrier to provide exogenous CO. CORM-3 [tricarbonylchloro (glycinato) ruthenium (II)] is completely soluble in water with fast release of CO when dissolved in a physiological solution.
By releasing CO, CORMs also induce an anti-inflammatory effect. Our previous study showed that CORM-2 reduced periodontal inflammation and alveolar bone resorption in rats with experimental periodontitis.
13 We also reported CORM-3 suppressed the expression of adhesion molecules in human gingival fibroblasts co-stimulated by tumor necrosis factor-α and interleukin-1 β,
