Enatiomeric separation of beta-blocking agents and analogs / 浙江大学学报·医学版

ABSTRACT

OBJECTIVE: To evaluate enantiomeric separation methods for beta-blocking agents and analogs. METHODS: Enantiomeric separation of racemates of 11 beta-blocking agents and their analogs was performed using chiral stationary phases and 2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl isothiocyanate (GITC). RESULTS: These beta -blocker racemates were separated into enantiomers in one or several chormatographic states such as propranolol, bisoprolol, metoprolol, celiprolol, carvedilol, sotalol, propafenone, ephedrine, and zomitriptan. Temperature had a significant effect on the resolution of the drugs when using chiralcel OD. Lower temperatures were associated with higher resolutions. CONCLUSION: When separating beta-blocking agents and their analogs, Chiralcel OD, Chiralpak AD, Chiral stationary phases and GITC chiral derivative reagents have complementary functions.
