Chiral analyses of dextromethorphan/levomethorphan and their metabolites in rat and human samples using LC-MS/MS.
Kikura-Hanajiri R, Kawamura M, Miyajima A, Sunouchi M, Goda Y. Kikura-Hanajiri R, et al. Anal Bioanal Chem. 2011 Apr;400(1):165-74. doi: 10.1007/s00216-011-4707-y. Epub 2011 Feb 11. Anal Bioanal Chem. 2011. PMID: 21311876
Most of the metabolites were detected as being the corresponding O-demethyl and N, O-didemethyl metabolites in the rat plasma and urine after the hydrolysis of O-glucuronides, although obvious differences in the amounts of these metabolites were found between the dextro and levo …

Tissues distribution of R-(-)- and S-(+)-m-nisoldipine after single enantiomer administration in rats.
Li M, Wang Q, Wang C, Jing X, Duan K, Chen X, Xu L, Tian Y, Zhang L, Du Y, Zhang X, Sheng X. Li M, et al. Drug Dev Ind Pharm. 2009 Jan;35(1):65-72. doi: 10.1080/03639040802183730. Drug Dev Ind Pharm. 2009. PMID: 18821195
All of the samples were prepared based on a simple and efficient liquid-liquid extraction method. After validating that no racemation occurred by ULTRON ES-OVM (Japan), m-nisoldipine enantiomers were determined, respectively, on a reverse-phase C(18) column (5 microm, 250 …
