eurjchem-1218	Shindy, Hassan Abazied; Goma, Maha Mubark; Harb, Nemat Abd El-Rahman	Synthesis, spectral behavior and biological activity of some novel 1,3,4-oxadiazine cyanine dyes	2015	6	.pdf	application/pdf	4792	212	57	Changing the quaternary salts in the monomethine cyanine dyes (7a‐c) from 1‐ethyl pyridinium‐yl salt in dye (7a) to 1‐ ethyl quinolinium‐4‐yl salt and/or 2‐ethyl isoquinolinium‐4‐yl salt to get dyes (7b) and/or (7c), discloses that the latter dyes have lower antimicrobial effects on the bacterial strains. Changing the type of the quaternary heterocyclic salt residue and/or their linkage positions in the dimethine cyanine dyes (9a‐c) from 1‐ethyl pyridinium‐2‐yl salt in dye (9a) to 1‐ethyl quinolinium‐2‐yl salt and/or 1‐ethyl pyridinium‐4‐yl salt to obtain dyes (9b) and/or (9c) declared that the former dye (9a) have higher antimicrobial activity for all the bacterial strains except staphylococcus aureus.	cache/eurjchem-1218.pdf	txt/eurjchem-1218.txt
