Introduction. In recent years, interest in the compounds of the benzofuroxane series has increased, because they have a wide range of biological activity, and in addition are donors of nitric oxide. In the scientific literature, many works are related to the synthesis and study of the biological activity of 5-nitro-4,6-dichlorobenzofuroxane amino derivatives, whereas amino derivatives of the 5,7-dichlor-4,6-dinitrobenzofuroxane substrate have been poorly studied.Aim. Is the synthesis of new amino derivatives of 5,7-dichloro-4,6-dinitrobenzofuroxane and the study of their biological activity.Materials and methods. Investigated the reaction of condensation of 5,7-dichloro-4,6-dinitrobenzofuroxane with different aromatic amines, containing functional groups of acceptor character in their structure were selected. In order to increase the yield for each specific reaction, the reaction conditions were selected (the reaction temperature, medium, and the amount of amine). The structure of the compounds confirmed IR, NMR spectra and elemental analysis.Results and discussion. New compounds in the 5,7-diamino-4,6-dinitrobenzofuroxane series were obtained. Acute toxicity, acaricidal and bacteriostatic activity against Escherichia coli and Staphylococcus aureus were studied. The obtained compounds were found to have high pharmacological activity, superior to the comparison drug (Chlorophos and Creolin).Conclusion. Most of the amino derivative synthesized 5,7-dichloro-4,6-dinitrobenzofuroxane have a high activity against mites and bacteria. Compounds containing in their structure chlorine and methyl radicals, have biological activity at low concentrations, are low-toxic and belong to the 4th hazard class.

Background & Objective:New diaryl-substituted pyrimidinedione compounds, their thioxo derivatives as well as their bicyclic thiazole compounds were synthesized and characterized.Methods:The glycosylamino derivatives of the synthesized disubstituted derivatives of the pyrimidine scaffold were also prepared via reaction of the N3-amino derivatives with a number of monosaccharides followed by acetylation.Results:The anticancer activity of the synthesized compounds was studied against human liver cancer (HepG2) and RPE-1cell lines. Compounds 2a, 2b, 3a and 12 showed potent activities with IC50 results comparable to that of doxorubicin.Conclusion:Docking investigations into Cyclin-dependent kinase 2 (CDK-2) enzyme, a potential target for cancer medication, were also reported showing the possible binding interaction into the enzyme active site to support their activity behavior.

The cyclization of 3-N(4- and 5-benzimidazolyl and benztriazolyl)amino-2-cyano- and 2-ethoxycarbonyl-2-propenoate esters Ia, b-IVa, b under the conditions of the Gould-Jacobs reaction leads to angularly ring-fused substituted imidazo or triazolo[4,5-f] (V, VI) and [4,5-h] (VII, VIII) quinolines, respectively. The esters Vb-VIIIb have been transformed into the corresponding chloroderivatives Vc-VIIIc. 3-N(5-Benzimidazolyl and 5-benztriazolyl)amino-2-cyano-2-propenenitriles are cyclized in the presence of aluminium(III) chloride to give the aminoquinolines Vd, VId. The structure of the products has been characterized by their 1H, 13C NMR, IR, and UV spectra.

Aziridine ring cleavage reactions of five N-nosylepimines (2-6) having D-talo, D-galacto, D-manno, and D-allo configurations with potassium hydrogendifluoride under various reaction conditions have been performed. The cleavage regioselectively afforded diaxial isomers of vicinal amino-fluoro derivatives of 1,6-anhydro-β-D-gluco- and mannopyranose 7-11 in 51-94% yields. Removal of 2-nitrobenzenesulfonyl protecting group with benzenethiol has been attempted in the case of compound 10.
