ORGANOSILICON COMPOUNDS -- DIOLS -- GLYCEROL
Аннотация: Biologically active hydrogels based on silicon polyolates, which are the products of reactions of tetraethoxy- and methyltriethoxysilanes with polyols (1,2-propanediol, glycerol, polyethylene glycol), were synthesized. The optimal conditions for hydrogel formation and hydrogel composition were determined. The acute toxicity and transcutaneous and wound-healing activities of the synthesized compounds were studied. The experimental results show that hydrogels based on silicon polyolates can be recommended for further preclinical and clinical tests with the purpose of their use in medical practice both as self-sufficient agents and ointment bases of pharmaceutical compositions with wound-healing, regenerative, and transcutaneous action

Аннотация: An improved method for the synthesis of fluoroalkyl-containing 3-hydroxyimino-1,5-benzodiazepines is proposed. For this, 3-hydroxyimines were obtained via nitrosation of 1,3-diketones and 3-oxoesters by tert-butylnitrite in diethylether under acid catalysis conditions and were reacted without isolation and further purification with ortho-phenylenediamine. It was found that polyfluoroalkyl-containing 3-hydroxyimino-1,5-benzodiazepin-2-ones and 2-hydroxy-3-hydroxyimino-2-trifluoromethyl-4-phenyl-1H-1,5-benzodiazepine possess high tuberculostatic activity comparable with that of isoniazide. Tests for acute toxicity of the trifluoromethylated heterocycles showed that they are less toxic than isoniazide

MICE -- TOXICITY -- TRIAZAVIRIN
Аннотация: The study of the toxicity of triazavirin, a new antiinfluenza agent, showed that the maximum concentration of the drug, inducing no microscopically visible changes in the structure of the monolayer and the cells of the MDCK and SKEV cell cultures, was 128 and 100 mcg/ml respectively. The maximum drug dose for single intraperitoneal administration inducing no signs of acute intoxication in albino mice weighing 10-12 g was 1000 mg/kg. In investigation of the chronic toxicity it was shown that oral administration of the drug (by 0.05 ml) to the albino mice in a dose of 200 mg/kg (maximum possible concentration by the solubility) daily for 10 days was well tolerated by the laboratory animals. The maximum tolerable dose of triazavirin for the albino mice was >200 mg/kg.

PYRIMIDINE -- ANTIMICOBACTERIAL -- TUBERCULOSIS
Аннотация: Combination of the Suzuki cross-coupling and nucleophilic aromatic substitution of hydrogen (SNH) reactions proved to be a convenient method for the synthesis of 5-styryl-4-(hetero)aryl substituted pyrimidines from commercially available 5-bromopyrimidine. All intermediate 5-bromo-4-(hetero)aryl substituted pyrimidines and also the targeted 5-styryl-4-(hetero)arylpyrimidines were found to be active in micromolar concentrations in vitro against Mycobacterium tuberculosis H37Rv, avium, terrae, and multi-drug-resistant strain isolated from tuberculosis patients in Ural region (Russia). It has been found that some of these compounds possess a low toxicity and have a bacteriostatic effect, comparable and even higher with that of first-line antituberculosis drugs

PYRAZINES -- ANTITUBERCULOSIS ACTIVITY -- 2(1H)-PYRAZINONE
Аннотация: A simple method based on hydrolysis of 2,3-dicyanopyrazinium salts has been used for the synthesis of the corresponding 5-(hetero)aryl-3-cyano-1-ethyl-2(1H)-pyrazinones. Also, the series of novel 1-ethyl-5-(hetero)aryl-1,6-dihydropyrazine-2,3-dicarbonitriles have been obtained through reduction of the same pyrazinium salts with triethylsilane. The obtained compounds proved to be active in micromolar concentrations in vitro against Mycobacterium tuberculosis H37Rv, Mycobacterium avium, Mycobacterium terrae, as well as against rifampicin and isoniazid-resistance strains of Mycobacterium tuberculosis. The data for acute in vivo toxicity in mice have been obtained for these compounds which appear to be promising antitubercular agents

Аннотация: The influence of Crossed D sign?2Crossed D signz2 on the degradation of 8-methoxypsoralen (8-MOP) in water-ethanol solutions under the action of KrCl and XeBr excilamp radiation in a photoreactor is investigated. A kinematic model of photodegradation of the investigated molecule is constructed. In water-ethanol solutions the addition of Crossed D sign?2Crossed D signz2 altered the mechanism of decay of 8-MOP under the action of a KrCl excilamp in comparison with irradiation by a XeBr excilamp. This behavior is explained by the fact that the action of 283 nm radiation leads to accumulation of a stable photoproduct. In order to establish the toxicity of this product further research is needed.

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.
