  • SYRINGE LABEL AND DRUG SOLUTION-FILLED SYRINGE USING THE SAME
    Publication number: 20160001012
    Abstract: Slightly above a rupture-intended line, a peripheral surface of a projection portion of a stopper cap is pushed in a direction from an outer side to an inner side (in an arrow direction). The stopper cap is pushed over on the principle of leverage in an oblique direction with, as a fulcrum P, the side (the back side) opposite in a circumferential direction to the side (the near side) at which a pushing force PW acts, so that an intermittent portion is ruptured due to bending of the flexible stopper cap. Then, a residual area remains at the syringe side, and a separation area is separated together with the stopper cap from the syringe to perform unsealing. Thus, a syringe label which allows for easy unsealing along the intermittent portion and with which an unsealed state is easily confirmed, and a drug solution-filled syringe using the label, are provided.

  • Process for the preparation of 6,7-diacyl-7-deacetylforskolin derivatives
    Patent number: 5610315
    Abstract: This invention relates to a process for the preparation of a 6,7-diacyl-7-deacetylforskolin derivative represented by the general formula: ##STR1## wherein R.sup.1 and R.sup.2 each stands for an acyl group and R.sup.3 stands for an aliphatic group having 2 to 3 carbon atoms, which comprises eliminating the acyl group at position 1 in a 1,6,7-triacyl-7-deacetylforskolin derivative represented by the general formula: ##STR2## wherein R.sup.1, R.sup.2 and R.sup.3 are as defined above, by solvolysis. The compound of the formula (I) is expected as medicine.
