Journal ArticleDOI
Synthesis, structure and antimicrobial activity of manganese(II) and cobalt(II) complexes of the polyether ionophore antibiotic Sodium Monensin A.
Petar Dorkov,Ivayla Pantcheva,William S. Sheldrick,Heike Mayer-Figge,Rositza Petrova,Mariana Mitewa +5 more
TL;DR: A preferable octahedral environment around the transition metal centers is observed in polar solvents while the complexes retain their tetrahedral structure in non-polar media.
Journal ArticleDOI
Crystal structure and properties of the copper(II) complex of sodium monensin A.
Ivayla Pantcheva,Petar Dorkov,Vasil Atanasov,Mariana Mitewa,Boris Shivachev,R. P. Nikolova,Heike Mayer-Figge,William S. Sheldrick +7 more
TL;DR: Compound 1 is effective against aerobic Gram(+)-microorganisms Bacillus subtilis, Bacillus mycoides and Sarcina lutea, and the antibacterial and antioxidant properties as two independent activities of 1 were studied.
Journal ArticleDOI
First divalent metal complexes of the polyether ionophore Monensin A: X-Ray structures of [Co(Mon)2(H2O)2] and [Mn(Mon)2(H2O)2] and their bactericidal properties.
Ivayla Pantcheva,Mariana Mitewa,William S. Sheldrick,Iris M. Oppel,Rumyana Zhorova,Petar Dorkov +5 more
TL;DR: These complexes are the first example of divalent metal complexes of the monovalent polyether ionophore and show greatly enhanced antimicrobial activity of complexes 2a-b against Gram(+)-bacteria.
Journal ArticleDOI
Alkaline-earth metal(II) complexes of salinomycin – spectral properties and antibacterial activity
TL;DR: In this article , the synthesis and structural characterization of alkaline-earth metal(II) complexes of the polyether ionophorous antibiotic salinomycinic acid (SalH2O) are discussed.
