Capillary Zone Electrophoresis Study of Naphthylethylcarbamoylated .beta.-Cyclodextrins
Analytical Chemistry, 1995Regiospecifically monosubstituted 1-(1-naphthyl)ethylcarbamoylated beta-cyclodextrins (NEC-beta-CDs) were successfully employed as chiral additives in capillary zone electrophoresis (CZE) to achieve chiral separation of N-(3,5-dinitrobenzoyl)phenylglycine (3,5-DNB-PG), phenylalanine (3,5-DNB-PA), and homophenylalanine (3,5-DNB-HPA).

Interaction between indometacin and beta-cyclodextrin.
Die Pharmazie, 1982CHINOIN-137 consists of indometacin and beta-cyclodextrin in a 1 : 2 molar ratio. solid phase analytical techniques, as thermal analysis, mass spectrometry and X-ray powder diffraction do not support the existence of a well-defined crystalline complex.

Effects of beta-cyclodextrin and hydroxypropyl-beta-cyclodextrin on stability of ranitidine HCl
Inclusion complexes of ranitidine HCI with β -cyclodextrin or 2-hydroxypropyl- β -cyclodextrin were prepared by means of co-grinding, freeze-drying and kneading techniques with three molar ratios (1:1, 1:2, and 2:1). Fourier-transform infrared spectra of both complex systems suggested that no strong chemical interaction was formed between the drug and ...openaire +1 more source
[Inactivation of soman by beta-cyclodextrin].
Comptes rendus de l'Academie des sciences. Serie III, Sciences de la vie, 1985Soman (pinacolyl methylphosphonofluoridate), a mixture of four stereoisomers, is inactivated appreciably in Tris buffer, pH 7.40, mu = 0.155 at 25 degrees C by beta-cyclodextrin (cycloheptaamylose, beta-CD). Under these conditions, the dissociation constant Kd of the 1:1 complex formed by beta-CD and soman and the rate constant k2 for the ...

Interaction of soman with beta-cyclodextrin.
Fundamental and applied toxicology : official journal of the Society of Toxicology, 1987Of the following neurotoxic agents, pinacolyl methylphosphonofluoridate (soman), isopropyl methylphosphonofluoridate (sarin) and ethyl N,N-dimethylphosphoramidocyanidate (tabun), only soman was inactivated appreciably at pH 7.40 by beta-cyclodextrin.
