Antimalarial dyes revisited: xanthenes, azines, oxazines, and thiazines.
In 1891 Guttmann and Ehrlich (P. Guttmann and P. Ehrlich, Berlin Klin. Wochenschr. 28:953-956, 1891) were the first to report the antimalarial properties of a synthetic, rather than a natural, material when they described the clinical cure of two patients after oral administration of a thiazine dye, methylene blue. Since that time, sporadic reports of the antimalarial properties of several xant...
متن کاملFar-Red Emitting Fluorescent Dyes for Optical Nanoscopy: Fluorinated Silicon-Rhodamines (SiRF Dyes) and Phosphorylated Oxazines.
Far-red emitting fluorescent dyes for optical microscopy, stimulated emission depletion (STED), and ground-state depletion (GSDIM) super-resolution microscopy are presented. Fluorinated silicon-rhodamines (SiRF dyes) and phosphorylated oxazines have absorption and emission maxima at about λ≈660 and 680 nm, respectively, possess high photostability, and large fluorescence quantum yields in water...
متن کاملFluorescence Efficiency of Laser Dyes *
The recent development of the dye laser [1] 1 has opened up an important new field of applications for organic dyes. This has led to a renewed interest in the theory of nonradiative transitions in dyes and also to the synthesis of new highly fluores cent dyes. In this article we review briefly the relations between fluor· escence and molecular structure in the most important classes of laser dy...
متن کاملAromaticity and relative stabilities of azines.
The most refined nucleus-independent chemical shift index (NICS(0)(πzz)) and the extra cyclic resonance energies (ECREs), based on the block localized wave function (BLW) method, show that the aromaticity of all azines is like that of benzene. The same is true for aza-naphthalenes relative to naphthalene. The lower relative energies of isomers with vicinal N's are due to the weakness of NN bond...
متن کاملThe role of oxygen radicals in dye-mediated photodynamic effects in Escherichia coli B.
Photosensitive dyes representative of the thiazines, xanthenes, acridines, and phenazines mediated phototoxicity in Escherichia coli B. The observed phototoxicity was sensitizer-, light-, and oxygen-dependent and is therefore a photodynamic effect. Hydroxyl radical scavengers conferred protection against the photodynamic action of all of the representative dyes. The extent of protection was dep...
