  • Patent number: 6399797
    Abstract: The present invention relates to compounds of formula (I), in which formula X is hydrogen or hydroxy or protected hydroxy; R1 an R2 stand for hydrogen, methyl or ethyl, or, when taken together with the carbon atom bearing the group X, R1 and R2 can form a C3-C5 carbocyclic ring; Q is a C3-C6 hydrocarbylene, hydrocarbylene indicating the diradical obtained after removal of 2 hydrogen atoms for a straight or banched, saturated or unsaturated hydrocarbon, in which one of any CH2 groups may optionally be replaced by an oxygen atom or a carbonyl group, such that the carbon atom (C-22) directly bonded to C-20 is an sp2 or sp3 hybridized carbon atom, i.e. bonded to 2 or 3 other atoms; and in which another of the CH2 groups may be replaced by phenylene, and where Q may optionally be substituted with one or more hydroxy or C1-C4-alkoxy groups.

  • Patent number: 6379330
    Abstract: A container (1) for a hypodermic syringe (3) and of the type which allows it to be seen or observed in another manner that the container has been opened. The container (1) comprises a plug (5) having more than one tamper-proof mechanism. This ensures both that the hypodermic syringe (3) can reach the user in a state which allows it to be seen whether it has been opened, and that, after use, it can be disposed of in such a state that re-use is impeded considerably.
