摘要:
A process is disclosed wherein an optically active N-mercaptoalkanoylamino acid is prepared by(1) reacting an optically active .beta.-hydroxyalkanoic acid, with a halogenating reagent to prepare an optically active .beta.-haloalkanoyl halide(2) reacting the .beta.-haloalkanoyl halide with an amino acid to produce an optically active N-.beta.-haloalkanoylamino acid and(3) reacting the N-.beta.-haloalkanoylamino acid with a reagent capable of converting the halogen into the thiol group, the configuration of the formulas (II), (III), (IV), (V), and (VI) being retained in all the optically active compounds throughout the process to prepare the compound represented by formula (I). The product of the present invention, for example, N-(3-mercapto-2-D-methylpropanoyl)-L-proline inhibits the enzymatic conversion of angiotensin I into angiotensin II and therefore is useful for relieving angiotensin-related hypertension.

A stable composition of S-adenosyl-L-methionine is disclosed which includes a salt of S-adenosyl-L-methionine and a pharmaceutically acceptable, water-soluble salt of a bivalent or trivalent metal. The salt of S-adenosyl-L-methionine is, for example, a salt of S-adenosyl-L-methionine with hydrochloric acid, sulfuric acid, p-toluenesulfonic acid, phosphoric acid, formic acid, acetic acid, citric acid, tartaric acid, or maleic acid; or a double salt of S-adenosyl-L-methionine with the foregoing acids. The salt of a bivalent or trivalent metal is, for example, calcium chloride, ferric chloride, magnesium chloride, or magnesium sulfate. A process for preparing the composition is also disclosed. The composition is suitable for preparing pharmaceutical preparations of S-adenosyl-L-methionine.
摘要:
A process is disclosed wherein D(-)-.beta.-hydroxyisobutyric acid is produced fermentatively from isobutyric acid or methacrylic acid by the stereoselective action of microorganisms having the ability to convert isobutyric acid or methacrylic acid into D(-)-.beta.-hydroxyisobutyric acid in an aqueous medium, and D(-)-.beta.-hydroxyisobutyric acid is recovered from the aqueous medium.
摘要:
A new antibiotic designated as auromomycin is prepared from the culture broth of Streptomyces macromomyceticus, a macromomycin-producing strain, as yellow crystals. Auromomycin is recovered in pure form from the culture broth by using hydrophobic chromatography with Octyl Sephalose CL-4B or Phenyl Sepharose CL-4B.

摘要:
A cutting apparatus configured to cut a sheet or a sheet bundle includes a cutting blade whose blade surface has a plurality of grooves. In the cutting apparatus, a scraping member enters the grooves provided on the blade surface to scrape off cutting scraps remaining after a cutting operation. Accordingly, the cutting apparatus can scrape off cutting scraps from the cutting blade even if the adhesive force of the cutting scraps is great.
摘要:
A sheet processing apparatus and an image forming apparatus are provided which can stabilize the shape of the spine after a squaring process. To square a spine Sb of a sheet bundle S, a spine processing apparatus 400 which squares the spine Sb performs squaring of the spine by moving the spine Sb which projects from a pair of first nipping rollers 405 and 406 while pressing the spine Sb by means of a pressing roller 411 in a state where the spine Sb is nipped by a pair of second nipping rollers 403 and 404.
摘要:
Disclosed is a capacitive touch panel device having a sensing control unit that performs a scan sequence on individual sensor electrodes to measure sensor output values. The sensing control unit exercises control to measure sensor output values, with setup performed to avoid the detection of sensitivity slope, by executing a first scan sequence on all sensor electrodes. If the result of the first scan sequence indicates that multiple points are touched, the sensing control unit exercises control to measure sensor output values again, with setup performed to allow the detection of sensitivity slope, by executing a second scan sequence on the sensor electrodes related to a plurality of touch position candidate coordinates derived from multiple point touches, and identify and eliminate erroneously detected coordinates in accordance with the sensor output values measured upon the execution of the second scan sequence and with the tendency of sensitivity slope.
摘要:
A capacitive touch panel has a plurality of first transparent electrodes and a plurality of second transparent electrodes on a transparent substrate. At crossing portions between the first and second electrodes, adjacent electrodes of the second electrodes have no interruption, and adjacent electrodes of the first electrodes are interrupted. An interlayer insulating film is disposed as an upper layer on the second electrodes, and a bridge electrode is disposed as an upper layer on the interlayer insulating film to connect interrupted portions of the first electrodes at the crossing portions. The material constituting the bridge electrode contains an element that is more susceptible to oxidation than elements contained in a material constituting the second electrodes. Constant voltage is applied to the first electrodes, and a pulse voltage having a low potential equal to or higher than the potential of the first electrodes is applied to the second electrodes.
