生物活性
EGTA 是一种特殊的钙离子螯合剂。EGTA 在生理 pH 值 (7.4) 下,Kd 为 60.5 nM,对 Ca2+ 比对 Mg2+ 有很高的特异性。EGTA 显著抑制炎性巨噬细胞的底物粘附能力。
体外研究
EGTA, proposed as endodontic irrigant, decreases substrate adherence capacity of inflammatory macrophages in a time- and dose-dependent manner. The EGTA concentration that causes an IC 50 is 202 mM. Chelators react with calcium ions in the hydroxyapatite crystals to produce a metallic chelate. Removal of calcium ions from the dentine makes the dentinal tissue softer, especially the hydroxyapatite-rich peritubular dentin and increases the diameter of exposed dentinal tubules.
