CARBORANES -- AZAHETEROCYCLES -- DECABORANE -- CROSS-COUPLING REACTIONS -- CARBORYNE
Аннотация: Azaheterocyclic derivatives of 1,2-dicarba- closo -dodeca borane (ortho -carborane) are known to be of particular interest due to numerous plausible applications, particularly, in medicine, materials science, and advanced technologies. 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.

AZAHETEROCYCLES -- BNCT -- CYTOTOXICITY -- CARBORANES
Аннотация: A series of novel water-soluble azaheterocyclic derivatives of nido-carborane bearing quinoxaline, 2H-imidazole or 1,2,4-triazine moieties were first synthesized in 82–91% yields. 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.

CYCLOMETALATED IRIDIUM COMPLEXES -- NEUTRON-CAPTURE THERAPY -- PHARMACOPHORES
Аннотация: For the first time, the direct C(sp(2))-H functionalization methodology has successfully been applied to cause nucleophilic modification of mono- and diazine-N-oxides with the 1,2-closo-carborane moiety. As a result of these cross-coupling reactions uncatalyzed by transition metals, a series of novel C-modified heterocyclic and open-chain (vinyl acetylene) carboranes have been obtained. Complexes of phenanthrolinyl-substituted omicron-carborane with Cu(II) of various architectures have been synthesized.

Аннотация: Liposomes encapsulated with lipophilic derivative of 1,2-dicarba-closo-dodecaborane have been obtained and tested for toxicity to glioblastoma U87 cells and biodistribution on a U87MG xenograft mouse model. The liposomes are able to penetrate the tumor and provide boron concentration up to 1.5 mmmmg g–1 with tumor-to-muscle ratio up to 2.4.

Аннотация: New purine derivatives containing a nido-carborane fragment were synthesized by nucleophilic substitution of chlorine atom in 6-chloropurine and 2-amino-6-chloropurine under the action of nido-carborane-containing amines. Compounds with significant activity against the acyclovir-resistant strain of herpes simplex virus type 1, as well as with moderate activity against influenza viruses A and B, were discovered for the first time among the synthesized nido-carboranyl derivatives of purine.

    1,3,7-triazapyrene-based ortho-carborane fluorophores: convenient synthesis, theoretical studies, and aggregation-induced emission properties / L. A. Smyshliaeva, M. V. Varaksin, E. I. Fomina [et al.] // Organometallics. - 2021. - Vol. 40, № 16. - P2792-2807
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: A convenient transition-metal-free approach, based on nucleophilic substitution of hydrogen (SNH), for consecutive regioselective C–H functionalization of 1,3,7-triazapyrene scaffolds with carboranyllithium and phenyllithium is reported. The theoretical calculations disclosed highlight key features in the regioselectivity and mechanism of the investigated SNH transformations. The novel 1,3,7-triazapyrene-based ortho-carboranes obtained have large potential in the field of molecular electronics as organic luminophores, which are characterized by the aggregation-induced emission and dual-emission effects.

Аннотация: The structures and characteristic features of the molecular packing patterns of complexes of pyridazines containing heterocyclic substituents and the carborane moiety with 2,3,5,6-tetrachlorohydroquinone (TCHQ) were investigated. It was shown that TCHQ can form supramolecular assemblies with carborane-containing substituted pyridazines. The stoichiometry and three-dimensional structures of these assemblies depend on the substituents in the pyridazine ring and are formed via O-H…N hydrogen bonding between TCHQ and heterocyclic molecules
