Abstract:

Antioxidant activities of minor pigments of sea urchins (1–5) and synthetic naphthazarins (7–13) were evaluated and compared with echinochrome A (6) using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonate) (ABTS) scavenging assays. Structure-activity relationships showed that the antioxidant activities of the tested compounds depended on the number and positions of hydroxyl groups. Compounds bearing 3 or 2 hydroxyl groups on a naphthazarin core (5,8-dihydroxy-1,4-naphthoquinone) were the most active in both assays. Echinochrome A (6) (IC50 7.0 μM) and it

Abstract:

Fifty natural and synthetic hydroxy-, aminohydroxynaphthazarins and related quinones were tested for their antiradical activities using 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonate) (ABTS) scavenging assay. The main features of structure-antiradical activity relationship of amino- and hydroxyquinones were determined for the first time. It was found that naphthazarins (5,8-dihydroxy-1,4-naphthoquinones) are much more active against ABTS-radical than related 1,4-naphthoquinones and 5-hydroxy-1,4-naphthoquinones.

Abstract:

We report the synthesis and characterization of iptycene–naphthazarin dyes by using a sequential Diels–Alder approach. The tautomerization of naphthazarin was used as the key step in the synthesis, with structures confirmed by single-crystal X-ray and NMR analysis. The systematic trends in electronic properties were investigated by UV/Vis spectroscopy. BF2 complexes of the dyes were prepared by reaction with BF3·OEt2 in CH2Cl2.

Abstract:

The ABTS•+ radical cation scavenging activity of known (2-5, 9, 10) and new (6-8) 1’-hydroxyethylnaphthazarins and their products of esterification and etherification was evaluated and a structure-activity relationship was studied. It was shown, that the structure of side chains does not affect the radical scavenging activity of 1’-hydroxyethylnaphthazarins and their derivatives. The presence of methoxyl groups on the naphthazarin core slightly enhanced the antioxidant activity of compounds compared with compounds without methoxyl groups.

The ABTS·+ scavenging activity of known (4, 6-8) and new (5, 9-12) naphthazarin-carbohydrate nonglycoside conjugates, and methoxynaphthazarins 1-3 was evaluated. The study of structure-activity relationships showed that the presence of carbohydrate fragments in the structure of naphthazarin-carbohydrate conjugates increased their antiradical activity compared with starting methoxynaphthazarins. Antiradical activity depends on the structure of carbohydrate fragments, their number, and position. Depending on the carbohydrate fragment the activity increased in the following order: methyl-α-d-gluc

Naphthoquinones, plants secondary metabolites are known for their antibacterial, antifungal, anti-inflammatory, anti-cancer and anti-parasitic properties. The biological activity of naphthoquinones is connected with their ability to generate reactive oxygen species and to modify biological molecules at their nucleophilic sites.

Abstract:

The antimicrobial effect of 5 naphthoquinones was tested against the phytopathogenic bacteria Erwinia carotovora. Disk diffusion tests and determination of minimal inhibitory concentrations (MIC) indicate that the compound naphthazarin (NTZ) has the best antibacterial activity among the naphthoquinones tested. Studies on the mode of action indicate the effect of NTZ was bactericidal at 10 µg/mL. When cultivation was done in the presence of sodium ascorbate, the restoration of E. carotovora growth was observed with 3 µg/mL NTZ, but not when a 10 µg/mL dose was used.

The concise synthesis of the lichen-derived antitumor agent hybocarpone (1) and its analogs is described. A new synthetic approach is based on the direct oxidative dimerization of the available naphthazarin precursors in the formation of the binaphtho[2,3- b; 2,3- d]furantetraone structure. It was shown that the first step to tetrahydrofuran features is the bridging hindered S*, S* and R*, S* carbon-carbon bonds of the molecules, setting the relative configurations of the 5a S*,6a S*,12a S*,12b S* and 5a S*,6a R*,12a R*,12b S* diastereomers.

Abstract:

6-Demethoxyaustrocortirubin (6) is synthesized via the epoxide (21) which is available in 73% yield over four steps from naphthazarin (10). Hydrolysis of the epoxide (21) yields the diol (25) which on hydrogenolysis affords 6-demethoxy-1-deoxyaustrocortirubin (7). Stereoselective benzylic hydroxylation of (7) gives (6). Cleavage of the epoxide (21) with sodium acetate in acetic acid affords a mixture of the esters (22)-(24), while methanolysis yields the isomeric ethers (29) and (30). Hydrogenolysis of (22), (23) and (29) gives high yields of (7). Potentially more direct routes to the alcohol
