Abstract | ||
Synthesis of new types of asymmetrical-2(3)-oxazolino - (pyrazolino)-4,3-b)-quinoline-2(4)- methine cyanine dyes including mono-, di-,trimethine cyanines (IVa-d,V,VIl a,b and IXa-d) was achieved by interaction of 4-hydroxy-2(3)-methyl oxazololino (pyrazlino)-4,3-b)-quinoline (la,b) with active components. The new cyanines were identified through IR and 1H NMR spectra. The electronic absorption spectra of the dyes in the visible region is reported. Bactericidal activty of selected cyanine dyes (IVa,IVd,V,VII6,1Xc) were tested against some bacterial strains. | ||
