Hybrids of a 9-anthracenyl moiety and fluorescein as chemodosimeters for the detection of singlet oxygen in live cells

Singlet oxygen (1O2) plays an important role in human innate immune response, plant physiology and anticancer photodynamic therapy (PDT). Therefore, its monitoring by convenient and sensitive methods (e.g. by detecting a fluorescence signal) by using non-toxic reagents would be advantageous. Known fluorogenic 1O2-chemodosimeters can potentially consume reducing agents in cells leading to the generation of toxic side products that limit their applications. In this paper we report on a series of 9-anthracenyl-fluorescein hybrids, which do not require any reducing agents for their reaction with 1O2. The selected compound 8d at a very low concentration of 100 nM is able to detect 1O2 in live human promyelocytic leukemia HL-60 cells with over 35-fold fluorescence signal enhancement within only 20 min assay time. This chemodosimeter is not toxic to HL-60 cells at concentrations ≤1 μM (higher concentrations were not tested) even at long incubation times ≤48 h.

Synthesis and electronic properties of sterically demanding N-arylphenothiazines and unexpected Buchwald-Hartwig aminations

(Chemical Equation Presented) Phenothiazine is coupled under Buchwald-Hartwig conditions with bromo anthracenes and perylene as substrates to give phenothiazine-anthracene and phenothiazine-perylene dyads and triads. Investigation of the electronic properties of these sterically demanding N-aryl phenothiazines by absorption and emission spectroscopy, cyclic voltammetry, and DFT calculations revealed that the individual chromophores are decoupled in the electronic ground state but show unique electronic communication in the excited state. For the anthracenyl-bridged diphenothiazine an intense electronic coupling of the phenothiazinyl units is detected upon oxidation. Besides, attempts to synthesize phenothiazine compounds with even more sterically demanding aryl substituents in the 10-position under N-arylation conditions gave rise to the formation of quite unexpected products of arylation and/or oxidative coupling. The folding angle of the phenothiazine in a consanguineous series correlates well with the first oxidation potential.

SYNTHESIS OF SUBSTITUTED tert-BUTYLANTHRAQUINONES

The oxidation of 2-methyl-5-tert-butyldiphenylmethane and its 4'-methyl-, chloro-, and nitro-substituded derivatives by potassium permangate in a mixture of pyridine and water leads to the formation of the correspoding 2-benzoyl-4-tert-butyl-benzoic acids, which are converted by the action of sulfuric acid with heat into substituted 2-tert-butylanthraquinones.The cyclization of 2-benzoyl-4-tert-butylbenzoic acids containig a tert-butyl group or chlorine atom in the benzoyl ring is accompanied by a Hayashi rearrangement, which leads to the formation of mixtures thecorresponding 2,6- and 2,7-disubstituted anthraquinones.

ALKYLATION OF ANTHRACENE BY tert-BUTYL ALCOHOL

The alkylation of anthracene by tert-butyl alcohol in the presence of trifluoro acetic acid or Lewis acids leads to the formation of 2-tert-butylanthracene and 2,6- and 2,7-di-tert-butylanthracenes.The ratio of 2,6- and 2,7-di-tert-butylanthracenes formed in the presence of trifluoroacetic acid and titanium tetrachloride is close to 75:25 and is determined by the relative alkylation rates of 2-tert-butylanthracene at positions 6 and 7.In the presence of aluminum chloride the ratio of the isomeric di-tert-butylanthracenes is 50:50 and is established as a result of the disproportionation and isomerization of the alkylation products.
