Abstract: The invention relates to novel antiviral compounds of general formula (I), where B is —N(R)2 or —O—(CH2)nN(R)2 groups, in which n is a whole number selected from 0, 1, 2, 3 and 4, each R is independently selected from C1-4 alkyl and can be identical or different, or both groups R together with a nitrogen atom, to which they are bonded, form a 5-6-membered heterocyclic ring containing 1-2 heteroatoms selected from nitrogen, oxygen and sulphur, such as pyrrolidine, piperidine, piperazine, morpholine or thyomorpholine, at which each of above-mentioned heterocyclic rings can be substituted by C1-4 alkyl, phenyl, benzyl, phenetyl, a carbonylamino —COOC1-4 alkyl group or the carbonylamino —COOC1-4 alkyl group and phenyl, which also can be substituted and have substituents selected from halogen, C1-4 alkyl, C1-4 alkoxy, and alkyl in said groups can be linear or branched; R1 is C1-4 alkoxy, phenyl optionally substituted by C1-4 alkyl or C1-4 alkoxy, halogen atoms, naphthyl; R2 is C1-4 alkyl, —S-phenyl, —S-benzyl, —O-

Abstract: The invention pertains to field of organic chemistry, medicine, pharmacology, foods and cosmetics industry, particularly, to manufacturing technology of selenoxanthenes; the invention may be used in manufacturing of food supplements, pharmaceutical and cosmetic products, having bioactive properties, of a wide spectrum of activity. The proposed compound is the ?-crystalline form of 9-phenyl-symmetrical-octahydroselenoxanthene with exhibits antioxidant, detoxifying, immunomodulating, anti-atherogenic, anti-sclerotic, anabolic and hypolipidemic properties, and has the following structural formula: Its powder X-ray diffractogram (obtained from a Cu-K X-ray source) has characteristic diffractions in degrees of the diffraction angle 2theta as 6.0, 12.0, 15.0, 17.0, 19.0, 20.0, 21.5, 21.7, 20.9, 25.0, 27.0, 28.0, 29.0, 37.0; the melting point of 96.8° C. The crystalline form of the respective 9-R-symmetrical-selenoxantene product is obtained by crystallization from a weakly polar or a non-polar solvent.

Abstract: The invention relates to medicine and veterinary. The device for magnetotherapy comprises a variable generator (1) of current pulses, an energy accumulator (2) and a circuit (3) for discharge of the energy accumulator (2), including a controlled switching element (5) and an inductor (4) capable of producing a therapeutic pulsed magnetic field, and also a unit (7) for controlling the duration of pulses of the magnetic field produced by the inductor (4) and a controller (10) of the amplitude of pulses of the magnetic field. According to the invention, the discharge circuit (3) of the energy accumulator (2) includes a unit (6) for controlling the slope of the leading edge of pulses of the magnetic field produced by the inductor (4). The device is predominantly intended for arresting and relieving acute pain syndromes, phantom limb pain and attacks of bronchial asthma, and also for treating mastities of cattle.
