New acyl derivatives of anthraquinone by interaction of 1-nitro-2-acylisothiocyanate- anthracenedione-9,10 with glycine, 2-aminobenzoic acid, aminothiazole, 2-mercaptobenzthiazole, o- phenylenediamine, thioglycolic acid and ethyl cyanoacetate were obtained. New derivatives of 1- nitro-2-acylisothiocyanate-anthracenedione-9,10 with antimicrobial activity against Staphylococcus aureus and Candida tenuis were determined. Perspective research directions of synthesized compounds on the base on biological screening in silico  were showed.

A convenient method of synthesis of 2-amino-4,9-dioxo-4,9-dyhidronaphto[2,3-b] thiophene-3-carboxylic acid by interaction of 2,3-dichloro-1,4-naphthoquinone with ethylcyanacetate and sulfide sodium in ethanol was developed.The influence of different factors was investigated and probable mechanism of reaction proposed. Розроблено зручний метод синтезу 2-аміно-4,9-діоксо-4,9-дигідронафто[2,3-b] тіофен-3-карбонової кислоти на основі взаємодії 2,3-дихлоро-1,4-нафтохінону з етилціаноацетатом та сульфідом натрію в етанолі.
