Abstract

The invention belongs to the field of drug analysis, and specifically discloses an HPLC detection method for valganciclovir hydrochloride intermediate condensate enantiomers. The method uses cellulose-tris(4-chloro-3-methylbenzene Base carbamate) coated silica gel as a chiral chromatographic column with a mixed solution of water and nitriles as the mobile phase, the column temperature is 10~20°C, the flow rate is 0.4~0.6ml / min, and the wavelength is 250 ~260nm. The invention realizes effective separation of four isomers of valganciclovir hydrochloride intermediate condensate, has good detection result accuracy, high sensitivity, simple operation, low cost and short analysis time, and is valganciclovir hydrochloride The quality control of intermediate condensate provides guarantee.

Description

technical field [0001] The invention belongs to the field of drug analysis, in particular to an HPLC detection method for condensate isomers of valganciclovir hydrochloride intermediates. Background technique [0002] Valganciclovir hydrochloride is a synthetic inhibitor of herpes virus DNA, developed by the Swiss company Roche, and first listed as a prescription drug in Sweden and Finland in 2010, for the treatment of giant cells in patients with acquired immunodeficiency syndrome (AIDS) Viral (CMV) retinitis and prevention of CMV infection in high-risk solid organ transplant patients. In March 2001, it was approved by the US FDA, and in May 2001 it was first launched in the US. A number of studies at home and abroad have shown that valganciclovir hydrochloride tablets have obvious pharmacological effects, novel mechanism of action, low toxicity, few adverse reactions, significant clinical efficacy, high patient compliance, and safe application. [0003] The intermediate ...
