This test in vitro makes it possible to determine the enzyme inhibitory activity of a substance by comparing the activity of a dissolved intestinal disaccharidase complex in the presence and absence of (100 value of inhibitor, 8 as a quality with: bstrata) use practically glucose-free sucrose (glucose 100 ppm). Definition The enzyme activity is based on the spectroscopic determination of glucose released by the reaction by glucose dehydrogenase and nicot amide adenine dinucleotide as a cofactor. One unit of sucrosease inhibitor (SIE) is defined as such inhibitory activity, which in a given initial test mixture restores a given saccharolytic activity per unit (unit of sucrase SE); a unit of sucrase determines the activity of enzymes, which, under these conditions, splits 1 µmol of sucrose per minute and this releases each time 1 µmol of glucose, which is determined by the test, and fructose, which is not detected by the test. The intestinal disaccharidase complex is obtained from the mucous membrane of the small intestine of the pig by tryptic digestion, precipitation from 66 ethanol at -20 ° C, absorption of the precipitate in 100 mM phosphate buffer pH 7.0 and dialysis against the buffer. 10 μl of the test solution, which is prepared so that the extinction of the initial mixture is less than 101 undiluted disaccharidase complex in 0.1 M maleic buffer pH 6.25, is preincubated at 37 ° C for 10 minutes. The dilution of the disaccharidase complex should be set to an activity of 0.1 SE / ml. Then, the saccharolytic reaction is started by adding 100 µl of a solution of O, m of sucrose (Serve 35579) in 0.1 m maleic buffer pH 6.25 after 20 min of incubation and the reaction is stopped by adding 1 ml of glucose-hydrogenase reagent (1 bottle of glucose mixture and lyophilized dehydrogenase (Megsk H053 and a solution of 331.7 mg | 1-nicotinamide-adenine dinucleotide (free acid, Beringer purity 1 in 250 ml of 0.5 M Tris buffer, pH 7.6, To determine glucose, the mixture is incubated in for 30 min at 37 ° C and then photometric with respect to the reagent at H / J (with the enzyme without sugar). The calculation of the inhibitory activity is complicated by the fact that a slight change in the test system, for example, a value of 100, which varies slightly from definition to definition, has an effect on the test result that cannot be ignored. These difficulties are avoided by the fact that with each definition a standard is also taken. The sucrose inhibitor of formula O, which has a specific inhibition activity of 77,700 SIE / r, serves as the standard. With knowledge of extinction differences at and and the value of 10 and the mixture hindered by the standard, 7loU + yO8 from the difference of extinction and inhibited 465000 SIE / r; 1-methoxycarbonylproduct solution of the mixture, taking vz-aminomethyl-1-deoxinoinomyrimycin the amount of inhibitor known-1500000 5 1E / g. to calculate his braking effect activity, expressed in units of im.The proposed method allows a sucrose killer per gram. to produce new compounds possessing Specific inhibitory secretion of chemical-pharmaceutical Activity: 1-deoxynomyurimicin properties.
