Basic research data were generalized on the synthesis and study of antiviral activity and the establishment of the metabolism and mechanism of azoloazine series compounds-azaanalogs of adenine and guanine, as well as their nucleosides, which led to the creation of a new family of antiviral substances. One of them, triazavirin, has become a regular therapeutic fixture as an antiflu preparation. The results of synthetic and biological studies on substituted pyrimidines, nucleosides of the benzimidazole and purine series, and other biologically active azaheterocycles are also discussed. \\\\expert2\\NBO\\Herald of the Russian Academy of Sciences\\2016.

Three principal synthetic strategies resulting in azaheterocyclic carboranes, in which boron-enriched and azaheterocyclic fragments are linked to each other, either directly by means of the C-C bonds or through a short spacer (CH 2, CH 2 S, CH 2 O, etc.), have been outlined. These synthetic approaches are of general character and can be used both individually and in combination to afford promising organoboron clusters of diverse architectures. 1 Introduction 2 C-C Cross-Coupling Strategies in the Synthesis of Azahetero cyclic Carboranes 3 Carboryne-Based Transformation Strategies 4 Condensation Strategies: Reactions of Decaborane B 10 H 14 with Substituted Acetylenes 5 Conclusion and Outlook. |

The structures of these boron-enriched compounds were confirmed by the data of NMR, IR spectroscopy, and mass spectrometry. To access the toxicity level for these organoboron compounds, the cytotoxicity indexes (IC50) were determined using by the MTT test on both human glioblastoma cell A-172 (IC50 = 150–243 μM) and human embryonic lung cells (IC50 = 424–944 μM) lines. The obtained preliminary results from in vitro analysis enable the synthesized water-soluble azaheterocyclic carboranes to be considered as challenging candidates in the design of agents for boron-neutron capture therapy (BNCT) of malignant tumors. |
