Аннотация: New anxiolytics have been discovered by prediction of biological activity with computer programs pass and derek for a heterogeneous set of 5494 highly chemically diverse heterocyclic compounds (thiazoles, pyrazoles, isatins, a-fused imidazoles and others). The majority of tested compounds exhibit the predicted anxiolytic effect. The most potent activity was found in 2-(4-nitrophenyl)-3-(4-phenylpiperazinomethyl)imidazo[1,2-a]pyridine 8, 1-[(4-bromophenyl)-2-oxoethyl]-3-(1,3-dioxolano)-2-indolinone 3, 5-hydroxy-3-methoxycarbonyl-1-phenylpyrazole 5 and 2-(4-fluorophenyl)-3-(4- methylpiperazinomethyl)imidazo[1,2-a]pyridine 7. The application of the computer-assisted approach significantly reduced the number of synthesized and tested compounds and increased the chance of finding new chemical entities (NCEs).

Аннотация: New 3-(1H-imidazol-2-yl)-9H-carbazoles and 6,6′-di(1H-imidazol-2-yl)-9H,9′H-3,3′-bicarbazoles have been prepared, starting from 9-ethyl-9H-carbazole-3-carbaldehyde or 9,9′-diethyl-9H,9′H-[3,3′-bicarbazole]-6,6′-dicarbaldehyde through their reactions with 4-methoxyaniline or 4-fluoroaniline, benzil or 2,2′-thenil [1,2-di(thien-2,2′-yl) glyoxal] and ammonium acetate on reflux in glacial acetic acid. The obtained compounds have been shown to demonstrate an effective fluorescence in the blue spectral region, exhibiting quantum yields in the range of 0.08–0.51, depending on their molecular structure and solvent polarity. The nature of the observed absorption spectra has been elucidated by the TDDFT calculations.

    Betaine–N-heterocyclic carbene interconversions of quinazolin-4-one imidazolium mesomeric betaines. sulfur, selenium, and borane adduct formation / S. L. Deev, E. Sheina, T. S. Shestakova [и др.] // European journal of organic chemistry. - 2020. - № 4. - С. 450-465

Аннотация: Reaction of N-alkylated imidazoles with 2-chloro-4-quinazolinone gave mesomeric betaines, 2-(1-alkyl-1H-imidazolium-3-yl)quinazolin-4-olates, for which three tautomeric forms of N-heterocyclic carbenes (NHCs) can be formulated, in addition to an anionic NHC after deprotonation. The NHC tautomers were trapped with sulfur, selenium, triethylborane, and triphenylborane as thiones, selenones and borane adducts, respectively. We obtained two isomers of the cyclic borane adducts, diazaboroloquinazolinones with [1,5-a] and [5,1-b]-type fusion between the quinazolinone and the diazaborole rings. They correspond to two different NHC tautomers and to the anionic NHC derived thereof. The third NHC tautomer was trapped as a non-cyclic adduct with tris(pentafluorophenyl)borane by coordination to the quinazoline oxygen atom. 2D 1H-15N HMBC experiments of 15N-labeled quinazolinone fragments, quantitative measurements of long-range 1H-15N coupling constants (JHN), and five X-ray single crystal analyses have been carried out for the structure elucidations and to gain insight into the NMR spectroscopic properties of these compounds.

    Design and antioxidant properties of bifunctional 2H-imidazole-derived phenolic compounds-a new family of effective inhibitors for oxidative stress-associated destructive processes / E. L. Gerasimova, E. R. Gazizullina, M. V. Borisova [et al.] // Molecules. - 2021. - Vol. 26, № 21. - Ст. 6534

2H-IMIDAZOLE -- POLYPHENOLS -- ANTIOXIDANT CAPACITY -- ANTIRADICAL CAPACITY
Аннотация: The synthesis of inhibitors for oxidative stress-associated destructive processes based on 2H-imidazole-derived phenolic compounds affording the bifunctional 2H-imidazole-derived phenolic compounds in good-to-excellent yields was reported. In particular, a series of bifunctional organic molecules of the 5-aryl-2H-imidazole family of various architectures bearing both electron-donating and electron-withdrawing substituents in the aryl fragment along with the different arrangements of the hydroxy groups in the polyphenol moiety, namely derivatives of phloroglucinol, pyrogallol, hydroxyquinol, including previously unknown water-soluble molecules, were studied. The structural and antioxidant properties of these bifunctional 5-aryl-2H-imidazoles were comprehensively studied. The redox transformations of the synthesized compounds were carried out. The integrated approach based on single and mixed mechanisms of antioxidant action, namely the AOC, ARC, Folin, and DPPH assays, were applied to estimate antioxidant activities. The relationship “structure-antioxidant properties” was established for each of the antioxidant action mechanisms. The conjugation effect was shown to result in a decrease in the mobility of the hydrogen atom, thus complicating the process of electron transfer in nearly all cases. On the contrary, the conjugation in imidazolyl substituted phloroglucinols was found to enhance their activity through the hydrogen transfer mechanism. Imidazole-derived polyphenolic compounds bearing the most electron-withdrawing functionality, namely the nitro group, were established to possess the higher values for both antioxidant and antiradical capacities. It was demonstrated that in the case of phloroglucinol derivatives, the conjugation effect resulted in a significant increase in the antiradical capacity (ARC) for a whole family of the considered 2H-imidazole-derived phenolic compounds in comparison with the corresponding unsubstituted phenols. Particularly, conjugation of the polyphenolic subunit with 2,2-dimethyl-5-(4-nitrophenyl)-2H-imidazol-4-yl fragment was shown to increase ARC from 2.26 to 5.16 (104 mol-eq/L). This means that the considered family of compounds is capable of exhibiting an antioxidant activity via transferring a hydrogen atom, exceeding the activity of known natural polyphenolic compounds.

    Synthesis, fungicidal activity, and molecular docking of 2-acylamino and 2-thioacylamino derivatives of 1 H-benzo[ d]imidazoles as anti-tubulin agents / K. L. Obydennov, T. A. Kalinina, N. A. Galieva [et al.] // Journal of agricultural and food chemistry. - 2021. - Vol. 69, № 40. - P12048-12062

BENZIMIDAZOLES -- ANTIFUNGAL ACTIVITY -- TUBULIN -- CARBENDAZIM
Аннотация: This work deals with the synthesis and evaluation of fungicidal activity of benzimidazole derivatives, which are structural analogues of commercial anti-tubulin fungicides. A number of N-acyl and N-thioacyl derivatives of 2-amino-1H-benzo[d]imidazole were prepared, and their fungicidal activity against 13 strains of phytopathogenic fungi was studied. The most active compounds against the majority of the studied strains were 3a, 4l, and 4o, and the EC50 values of these compounds were in the range 2.5–20 μg/mL. Compound 3a showed the highest activity against the P. infestans strain, the growth of which is not suppressed by carbendazim. The formation of ligand–receptor complexes of various tautomeric forms of the studied benzimidazoles with homologous models of β-tubulins of B. cinerea, F. oxysporum, and P. infestans was modeled. Induced fit docking has been used for the simulation. The obtained data suggest the possibility of binding of benzimidazole fungicides to β-tubulin in the ″nocodazole cavity″ in the tautomeric form bearing a double exocyclic C═N bond. The importance of the formation of hydrogen bonds of benzimidazoles with the amino acid residue Val236 along with the Glu198 residue is also revealed in the present study.
