Sažetak

The interactions O'f metal chlorides (MeClz) of group !La
(Me = Mg, Ca, Sr, Ba) and group !lb (Me = Zn, Cd, Hg) with
ribavi.rin, a potent broad spectrum antiviral nucleoside, and with
.Us structural analogue inosine were studied in DMSO-ds using
1H and 130 NMR methods. Proton limiting shift analysis was
made and 1H and 130 spin lattice relaxation times oif ribavirin
as a function o:f metal ion concentrations were determined.
The nature of the interactions was determined on the basis of
these data. The composition 01f comple1xes was determined using
J0 and Me2+-inosine complexoo in equilibrium were evaluated
either by concentration dependence or by a variaible temperature
method.
