which provides a symptomatic relief to patients. Reaction of carbidopa with cis-[Cr(C2O4)2(H2O)2]– has been carried out in aqueous medium over the range 35 ≤ t ≤ 50 ºC, 4.0 ≤ pH ≤ 6.0 , 3.75 × 10-3 mol dm-3 ≤ [carbidopa] ≤ 9.38 × 10-3 mol dm-3, I (KNO3) = 0.1 mol dm-3. There is outersphere association between cis-[Cr(C2O4)2(H2O)2]– and conjugate base of carbidopa followed by first chelation. The characterization
对于第二常见的神经退行性疾病帕金森病的治疗,需要将左旋多巴与外周脱羧酶抑制剂(例如卡比多巴)联合使用,以缓解患者的症状。卡比多巴与顺式-[Cr(C2O4)2(H2O)2]– 的反应在水介质中进行,反应温度范围为 35 ≤ t ≤ 50 ℃, 4.0 ≤ pH ≤ 6.0 , 3.75 × 10-3 mol dm-3 ≤ [卡比多巴] ≤ 9.38 × 10-3 mol dm-3,I (KNO3) = 0.1 mol dm-3。顺式-[Cr(C2O4)2(H2O)2]– 与卡比多巴的共轭碱之间存在外层缔合,然后进行第一次螯合。通过核磁共振和红外光谱对产物进行表征。该产品比左旋多巴和卡比多巴的组合表现出更好的抗帕金森病活性
