摘要:
The invention discloses triacetyl-3-hydroxyphenyladenosine represented by formula (I), the preparation, the pharmaceutical composition and the use thereof. Specially, the invention discloses a new compound of 2′,3′,5′-tri-O-acetyl-N6-(3-hydroxyphenyl)adenosine. Using hypoxanthine nucleoside as starting material, the compound is prepared by acetylating with acetic anhydride, chlorinating with thionyl chloride, and being substituted with 3-hydroxy aniline. The invention also discloses the pharmaceutical composition comprising triacetyl-3-hydroxyphenyladenosine. The dosage forms of the said pharmaceutical composition include tablet, capsule, pill, injection, sustained release preparation, controlled release preparation or particulate delivery system. The medicament for treatment or precaution of hyperlipemia prepared by the compound of the invention has the advantages of significant hypolipidemic activity, less toxicity and adverse effect as well as slow metabolism in vivo.

摘要:
The present invention creates a new way of arranging harsh marks on a reticle that is to have the 2/10th and the 4/10th hash mark placed either above or below the horizontal base sighting line (See FIG. 2. Line 26) or on the left or right side of the vertical sighting base line (See FIG. 2. Line 27) at any unit of measurement of a segment and have the 6/10th and the 8/10th hash mark placed at the opposite side of the horizontal base sighting line (See FIG. 2. Line 26) and the vertical sighting lines (See FIG. 2. Line 27) compared with the 2/10th and the 4/10th marks.This new way of placing hash marks at every 2/10th of the unit of measurement allows a user to quickly identify and discern which numerical value a hash mark represents on the horizontal base sighting line and vertical sighting line without physically counting the numerical value of a hash mark in a linear way. The said hash marks are being referred to the vertical or horizontal dividing lines that divide a segment at any unit of measurement of a generally horizontal base sighting line or a generally vertical sighting line into equal fractional parts of the segment.
