Synthesis of diastereomeric anhydrides of (RS)-ketorolac and (RS)-etodolac, semi-preparative HPLC enantioseparation, establishment of molecular asymmetry and recovery of pure enantiomers

17-Jan-2018 | Poonam Malik; Ravi Bhushan, New Journal of Chemistry, 2018

Herein, enantioseparation of two anti-inflammatory drugs, namely, (RS)-ketorolac and (RS)-etodolac, commonly marketed and administered as racemates, was achieved by RP-HPLC. This method provided very low limit of detection values (3.69 and 3.02 ng mL−1 for diastereomeric derivatives of (R)- and ...

Synthesis and Functional Characterization of Caffeic Acid Glucoside Using Leuconostoc mesenteroides Dextransucrase

28-Mar-2017 | Seung-Hee Nam; Young-Min Kim; Marie K. Walsh; Young-Jung Wee; Kwang-Yeol Yang; Jin-A Ko; Songhee Han; Thi Thanh Hanh ..., Journal of Agricultural and Food Chemistry, 2017

Caffeic acid was modified via transglucosylation using sucrose and dextransucrase from Leuconostoc mesenteroides B-512FMCM. Following enzymatic modification, a caffeic acid glucoside was isolated by butanol separation, silica gel chromatography, and preparative HPLC. The synthesized caffeic acid ...
