So far, no detailed view has been expressed regarding the interactions between vancomycin and racemic compounds including mandelic acid. In the current study, a chiral stationary phase was prepared by using 3-aminopropyltriethoxysilane and succinic anhydride to graft carboxylated silica microspheres and subsequently by activating the carboxylic acid group for vancomycin immobilization. Characterization by elemental analysis, Fourier transform infrared spectroscopy, solid-state nuclear magnetic resonance, and thermogravimetric analysis demonstrated effective functionalization of the silica surface. R and S enantiomers of mandelic acid were separated by the synthetic vancomycin column. Finally, the interaction between vancomycin and R/S mandelic acid enantiomers was simulated by Auto-dock Vina. The binding energies of interactions between R and S enantiomers and vancomycin chiral stationary phase were different. In the most probable interaction, the difference in mandelic acid binding energy was approximately 0.2 kcal/mol. In addition, circular dichroism spectra of vancomycin interacting with R and S enantiomers showed different patterns. Therefore, R and S mandelic acid enantiomers may occupy various binding pockets and interact with different vancomycin functions. These observations emphasized the different retention of R and S mandelic acid enantiomers in vancomycin chiral column. 相似文献

Congenital malformations and genetic diseases in Iranian infants 总被引:1,自引:0,他引:1
Summary Data of 13,037 live-born infants from a hospital in Tehran, Iran were analysed for congenital malformations and genetic diseases. The results showed that the rates of joint dislocation, eleft lip, cleft palate and finger anomalies are similar to those of the other populations. The rates of chromosomal, thorax and abdominal, external genital anomalies and other syndromes were higher compared with other populations, whereas the rates of multiple births and limb anomalies were lower. 相似文献
