About paper

Funding: the study was carried out under the State Assignment for FMBA № 22.001.18.800.

Author contribution: Aldobaev VN planned the experiment, summarized its results and wrote this manuscript; Mikhina LV carried out the experiment in animal models; Present MA synthesized the tested compounds.

Compliance with ethical standards: the study was approved by the Ethics Committee of the Research Centre for Toxicology and Hygienic Regulation of Biopreparations (Protocol № 695 dated November 12, 2019). Housing conditions met the requirements of Sanitary Regulations 2.2.1.3218-14 (Sanitary and Epidemiological Requirements for Design, Equipment and Maintenance of Vivarium Facilities) and the guidelines provided in the Guide for Care and Use of Laboratory Animals (ILAR publication, 1996, National Academy Press, USA).
