Abstract:
The invention relates to biotechnology. The protein-polypeptide complex which has a tissue-specific regenerative, reparative and rejuvenating effect on skin tissue is produced from nerve and skin tissues of embryos of hoofed agricultural animals within a gestation period from the middle of the first trimester to the middle of the final trimester of pregnancy by homogenizing said tissue in a buffer solution with simultaneous extraction in the presence of reversible proteolysis inhibitors, non-ionic detergents and solubilizers at a pH of 5.2-8.5. The homogenate produced is centrifuged and filtered. The proteins are separated out on a chromatography column using an anion-exchange medium. The fractions produced are combined and subjected to sterilizing filtration. The complex comprises negatively charged, weakly acid, neutral proteins and polypeptides having molecular masses of from 0.5 to 200 kDa. The complex is characterized by an absorption peak at a wavelength of 215±5 nm upon plotting of the ultraviolet spectrum in a wavelength range of from 200 to 500 nm. The pharmaceutical composition comprises, as active ingredient, the protein-polypeptide complex in a concentration of 0.01-2.0 mg/ml, polynucleotides in the form of a sodium salt of deoxyribonucleic acid, and a pharmaceutically acceptable diluent.
Abstract:
The present invention relates to novel quinoline derivatives, such as substituted 1-(2-chloroquinolin-3-yl)-4-dimethylamino-2-(naphthalen-1-yl)-1- phenylbutan-2-ols, to a method for producing same, and also to the use thereof as antimycobacterial agents, in particular to 5,6,7-substituted 1-(2-chloroquinolin-3-yl)-4-dimethylamino-2-(naphthalen-1-yl)-1- phenylbutan-2-ols of general formula (I), where R1 is Н or methoxy, R2 is Н, methoxy or -O-(CH2)n-O-, R3 is Н, methoxy or -O-(CH2)n-O-, n=1-2, and also to the pharmaceutically acceptable salts thereof with acids which exhibit activity in relation to mycobacteria. The invention also relates to a method for producing compounds of formula (I), which consists in interacting corresponding arylquinolines with an aromatic ketone and using said compounds as an active principle in the creation of anti-tubercular medicinal preparations.
Abstract:
The invention relates to a cyclic octapeptide which is a somatostatin analogue, and can be used to produce a radiopharmaceutical agent having the formula (Ia) or (Ib) with the radionuclides 111In, 90Y, 177Lu. The radiopharmaceutical agent can be used to treat tumours that express somatostatin receptors. (lа), (lb) X = a chelating agent
