中文摘要: |
采用紫外分光光度法,在225 nm 与305 nm波长处测得泛昔洛韦的解离常数pKa均为3.8.在含有泛昔洛韦的pH值为7.0的Na2HPO4-KH2PO4缓冲溶液中加入牛血清白蛋白,以双倒数公式法测定二者的结合常数.结果表明,牛血清白蛋白与泛昔洛韦形成了1∶4的配合物,其结合常数是4.51×106 L/mol.方法简便,结果可靠. |
英文摘要: |
Both the dissociation constants of famciclovir obtained were 3.8 using ultraviolet spectrophotometry with the wavelengths at 225 nm and 305 nm. Bovine serum albumin was added to a Na2HPO4-KH2PO4 buffer solution (pH 7.0) with famciclovir. The binding constant was measurd by the double-reciprocal analysis. The results showed that bovine serum albumin and famciclovir formed a 1∶4 complex, and the binding constant obtained was 4.51×106 L/mol. This method is simple and reliable. |
