چکیده
The constitution of vacidin A, a representative of the aromatic heptaene macrolide antibiotics was established on the basis of 13C and 1H-1H double quantum filtered correlated spectroscopy, rotating frame nuclear Overhauser effect spectroscopy, J-resolved 1H as well as 1H-13C correlation NMR spectra. Geometry of the polyene chromophore was determined as 22E,24E,26E,28Z,30Z,32E,34E.

The structure of vacidin A, an aromatic heptaene macrolide antibiotic. II. Stereochemistry of the antibiotic.
On the basis of coupling constants and rotating frame nuclear Overhauser effect spectroscopy of vacidin A methoxycarbonylmethylamide, the stereochemistry of the antibiotic was established. The configuration of the aglycone was determined as (3R,7R,9R,11S,13S,15R,17S,18R,19S,21R, 36S,37R,38S). The aminosugar constituent of the antibiotic was identified as beta-(D)-mycosamine. The chiral center a...
متن کاملExperimental and theoretical characterization of a new Schiff-base ligand
Here, new N,N′-dipyridoxyl(4,4''-diaminodiphenylether) Schiff-base ligand has been synthesized and characterized by IR, 1H NMR and mass spectrometry. Also, geometry optimization and theoretical assignment of IR spectrum of the ligand have been computed by employing density functional theory (DFT) method. Two pyridine rings and benzene rings in the bridge region are not in the same plane. The ca...
متن کاملDetermining whether positively-charged channel-forming molecules of polyene antibiotic with aromatic groups affect muscle activity?
This article evaluates the effect of membrane active channel-forming polyene antibiotic (PA) of levorin and its alkyl derivatives on the muscle performance. The membrane channels of muscle cells are capable to transport ions of potassium, sodium, and calcium. In the period of an intensive muscle exercise, the necessity for organic substrates increases and these channels start to work with the g...

متن کاملSequence of biosynthesis of the components of the polyene macrolides candidin and candihexin: macrolide aglycones as intracellular components.
A sequential formation of the single components of the polyene macrolide candidin complex (heptaene) has been found. In addition to the three components occurring in the candidin complex at the end of the fermentation, two other "early" all-trans heptaene components have been characterized. They exist only during the phase of active biosynthesis of candidin. Two of the components of the polyene...
