Nevertheless, the search and application of new low-toxic and effective drugs, combined with the timely diagnosis of diseases, makes it possible to cure most types of tumors at an early stage. In this work, the range of new polysubstituted 4,7-dihydro-6-nitroazolo[1,5-a]pyrimidines was extended. The structure of all the obtained compounds was confirmed by the data of 1H, 13C NMR spectroscopy, IR spectroscopy, and elemental analysis. These compounds were evaluated against human recombinant CK2 using the ADP-GloTM assay. In addition, the IC50 parameters were calculated based on the results of the MTT test against glioblastoma (A-172), embryonic rhabdomyosarcoma (Rd), osteosarcoma (Hos), and human embryonic kidney (Hek-293) cells. Compounds 5f, 5h, and 5k showed a CK2 inhibitory activity close to the reference molecule (staurosporine). The most potential compound in the MTT test was 5m with an IC50 from 13 to 27 \u00b5M. Thus, our results demonstrate that 4,7-dihydro-6-nitroazolo[1,5-a]pyrimidines are promising for further investigation of their antitumor properties.<\/jats:p>","DOI":"10.3390\/molecules27165239","type":"journal-article","created":{"date-parts":[[2022,8,17]],"date-time":"2022-08-17T22:53:30Z","timestamp":1660776810000},"page":"5239","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["CK2 Inhibition and Antitumor Activity of 4,7-Dihydro-6-nitroazolo[1,5-a]pyrimidines"],"prefix":"10.3390","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4742-6044","authenticated-orcid":false,"given":"Daniil N.","family":"Lyapustin","sequence":"first","affiliation":[{"name":"Department of Organic and Biomolecular Chemistry, Ural Federal University, Mira St. 19, 620002 Ekaterinburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Svetlana K.","family":"Kotovskaya","sequence":"additional","affiliation":[{"name":"Department of Organic and Biomolecular Chemistry, Ural Federal University, Mira St. 19, 620002 Ekaterinburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilya I.","family":"Butorin","sequence":"additional","affiliation":[{"name":"Department of Organic and Biomolecular Chemistry, Ural Federal University, Mira St. 19, 620002 Ekaterinburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Evgeny N.","family":"Ulomsky","sequence":"additional","affiliation":[{"name":"Department of Organic and Biomolecular Chemistry, Ural Federal University, Mira St. 19, 620002 Ekaterinburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vladimir L.","family":"Rusinov","sequence":"additional","affiliation":[{"name":"Department of Organic and Biomolecular Chemistry, Ural Federal University, Mira St. 19, 620002 Ekaterinburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9645-3324","authenticated-orcid":false,"given":"Denis A.","family":"Babkov","sequence":"additional","affiliation":[{"name":"Department of Pharmacology & Bioinformatics, Scientific Center for Innovative Drugs, Volgograd State Medical University, 400131 Volgograd, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0474-5005","authenticated-orcid":false,"given":"Alexander A.","family":"Pokhlebin","sequence":"additional","affiliation":[{"name":"Department of Pharmacology & Bioinformatics, Scientific Center for Innovative Drugs, Volgograd State Medical University, 400131 Volgograd, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7185-4826","authenticated-orcid":false,"given":"Alexander A.","family":"Spasov","sequence":"additional","affiliation":[{"name":"Department of Pharmacology & Bioinformatics, Scientific Center for Innovative Drugs, Volgograd State Medical University, 400131 Volgograd, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vsevolod V.","family":"Melekhin","sequence":"additional","affiliation":[{"name":"Department of Organic and Biomolecular Chemistry, Ural Federal University, Mira St. 19, 620002 Ekaterinburg, Russia"},{"name":"Department of Biology, Ural State Medical University, Repina 3, 620014 Yekaterinburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria D.","family":"Tokhtueva","sequence":"additional","affiliation":[{"name":"Department of Organic and Biomolecular Chemistry, Ural Federal University, Mira St. 19, 620002 Ekaterinburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2361-5887","authenticated-orcid":false,"given":"Anna V.","family":"Shcheglova","sequence":"additional","affiliation":[{"name":"Department of Organic and Biomolecular Chemistry, Ural Federal University, Mira St. 19, 620002 Ekaterinburg, Russia"},{"name":"Department of Biology, Ural State Medical University, Repina 3, 620014 Yekaterinburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oleg G.","family":"Makeev","sequence":"additional","affiliation":[{"name":"Department of Biology, Ural State Medical University, Repina 3, 620014 Yekaterinburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,17]]},"reference":[{"key":"ref_1","unstructured":"Ferlay, J., Ervik, M., Lam, F., Colombet, M., Mery, L., Pi\u00f1eros, M., Znaor, A., Soerjomataram, I., and Bray, F.
