Structure of 1:1 complex of 1-naphthylmethyl ester of monensin A with sodium perchlorate studied by X-ray, FT-IR and ab initio methods

“…[23]. The purity of this compound was controlled by elemental analysis, FT-IR, 1 H and 13 C NMR spectroscopic methods.…”

“…Over the last decade, extensive X-ray crystallographic and spectroscopic studies of the three-dimensional structure of monensin salts [11][12][13][14][15][16][17][18][19], monensin derivatives [20][21][22] and their complexes with monovalent [23][24][25][26][27][28][29][30][31] and divalent cations [32][33][34] have taken us to a new level of understanding of the mechanism and function of the ionophoric antibiotics. Among the new remarkable features revealed by structural studies, is the proton channel formation by monensin A methyl ester [35], complexation of divalent cation by monensin [14][15][16][17][18][19] and its derivatives [32][33][34].…”

Crystal structure and FT-IR study of aqualithium 1-naphthylmethyl ester of monensin A perchlorate

“…[31]. The purity of this compound was controlled by elemental analysis, FT-IR, 1 H and 13 C NMR spectroscopic methods [31].…”

“…Up to now, we have synthesised several new esters and amides of monensin and studied their abilities to form complexes with monovalent and divalent metal cations using mass spectrometry, spectroscopic and semiempirical methods [21][22][23][24][25][26][27][28][29][30][31][32][33][34]. We have also shown that various modifications of monensin influence the affinity of the new derivatives of monensin towards monovalent and divalent cations as well as the stability of the respective complexes.…”

Complexes of lasalocid 2-naphthylmethyl ester with monovalent metal cations studied by mass spectrometry, spectroscopic and semiempirical methods

“…It was shown that the biological activity of ionophores, their esters and amide derivatives and their complexes with metal cations and N-bases depends strongly on their structures. Thus, it is very important to establish detail information on these structures [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. For a detail study of the complexation of metal cations by a new derivative of lasalocid acid, we have chosen its 2-naphthylmethyl ester (NAFB), previously obtained by us and studied by X-ray crystallography [25].…”
