  • Patent number: 6849631
    Abstract: The present invention relates to the synthesis of a new class of indeno [1,2-c]pyrazol-4-ones of formula (I): that are potent inhibitors of the class of enzymes known as cyclin dependent kinases, which relate to the catalytic subunits cdk1-7 and their regulatory subunits know as cyclins A-G. This invention also provides a novel method of treating cancer or other proliferative diseases by administering a therapeutically effective amount of one of these compounds or a pharmaceutically acceptable salt form thereof. Alternatively, one can treat cancer or other proliferative diseases by administering a therapeutically effective combination of one of the compounds of the present invention and one or more other known anti-cancer or anti-proliferative agents.

  • Patent number: 6220450
    Abstract: A device to separate rubber stoppers that have adhered together, typically as a result of sterilization. The device contains a hopper, a pair of rollers and a mechanism to turn the rollers. The rollers are hexagonal-shaped and each face has a scalloped concavity. The adhering stoppers are gravity-fed into the rollers from the hopper, where they are compressed and a shearing force is applied to separate the adherent stoppers. The separated stoppers are then collected for further processing.
