  Monensin A benzyl ester and its complexes with monovalent metal cations studied by spectroscopic, mass spectrometry and semiempirical methods

  摘要：

  Monensin A benzyl ester (MON3) was synthesized and its ability to form complexes with Li+, Na+ and K+ cations was studied by ESI MS, H-1 and C-13 NMR, FT-IR and PM5 semiempirical methods. MON3 has been found to preferentially form complex with Na+ cations. The formation of stable complexes of 1: 1 stoichiometry up to cv = 70 V is indicated in the electrospray ionisation mass spectra. With increasing cone voltage value, the fragmentation of the respective complexes is detected and is connected primary with the dehydration process. The structures of the complexes are stabilized by intramolecular hydrogen bonds in which the OH groups are always involved. The structures of MON3 and its complexes with Li+, Na+ and K+ cations are visualized and discussed in detail. It is shown that in the structure of MON3 the oxygen atom of this C=O ester group is involved in very weak bifurcated hydrogen bonds with two hydroxyl groups. Within the complexes of MON3 with Li+ and K+ cations, this C=O ester group is not hydrogen bonded, whereas in the structure of MON3 with Na+ it can also coordinate this cation. Such a structure is, however, not dominant in acetonitrile solution. It is demonstrated that the formation of a pseudo-crown ring structure formed by MON3 prefers the complexation of Na+ cations.

  日期：——

  Bis-monensin derivatives were synthesized and characterized for the first time as chiral receptor molecules. Among them, o-xylene-bridged bis-monensin exhibited particularly excellent chiral recognition ability by the inclusion of chiral ammonium guest cations in its central cavity.

  Methods for controlling growth of gram negative bacteria, such as Helicobacter pylori, which are agents associated with disorders of the gastrointestinal tract of a mammal are described. They include administering a therapeutically effective amount of a polyether ionophore antibiotic to a mammal, such that growth of gram negative bacteria which are agents associated with disorders of the gastrointestinal tract of a mammal is controlled. Packaged pharmaceutical compositions for controlling gram negative bacteria are also described. The packaged compositions include a container holding a therapeutically effective amount of a pharmaceutical composition for controlling gram negative bacteria which are agents associated with disorders of the gastrointestinal tract of a mammal and instructions for using the pharmaceutical composition for control of the gram negative bacteria, such that growth of gram negative bacteria which are agents associated with disorders of the gastrointestinal tract of a mammal is controlled. The pharmaceutical composition includes at least one polyether ionophore antibiotic or a bicyclic spiroether.

  The esters (2-10) of the ionophore antibiotic Monensin (1) were synthesized by four different methods, which are discussed in detail. These new esters were characterized by various spectroscopic techniques and subsequently tested in the face of their antimicrobial properties. Three derivatives (3, 8 and 10) showed activity against Gram-positive bacteria. Additionally derivative (10) exhibited a relatively low antifungal activity against Candida in contrast to Monensin A.
