also measured, indicating the tight binding of NO by the Ru I I I complexes. The activity of the Ru I I I complexes to scavenge nitric oxide was evaluated using RAW264 murine macrophage cells. Ligand analogues of edta that have a pyridine donor as part of the N,N chelate such as 20 and 24 exhibit similar scavenging activity to the parent compound. Ligand analogues of dtpa that have R groups at the central
在这项研究中,生产了一系列由乙二胺四乙酸 (edta) 和二亚乙基三胺五乙酸 (dtpa) 的类似物螯合的 Ru III 配合物,并测试了 NO 清除能力。对 edta 和 dtpa 配体框架进行了修改,以改变所得 Ru III 配合物的反应性、水性稳定性和药代动力学。亚硝酰基配合物 38 的 X 射线结构证实 Ru III 配合物 27 与 NO 反应形成线性 Ru-NO} [ 6 ] 配合物。亚硝酰基络合物 [C 1 5 H 1 5 N 4 O 1 1 Ru] 在 P2 1 /c 空间群中结晶,a = 12.731(3) A, b = 10.894(2) A, c = 14.241 (3) A , β = 107.320(4)°, V = 1885.6(7)A 3 , and Z = 4. 14 (k = 2.38×10 6 M - 1 s - 1 )和27 (k = 2)反应的动力学研究
