    Abstract: An adhesive is provided containing at least one synthetic polymer with receptor sites that enable the selective capture or release of a target molecule. A polymer is synthesized by polymerizing and cross-linking a functional monomer or functional copolymers in the presence of a target or template molecule allowing for reversible interactions between the polymer and the target molecule. The target molecule may be extracted from the polymer creating receptor sites complimentary to the target molecule. Alternatively, the target molecule may remain in the polymer network and be controllably released. The molecularly imprinted polymer is formulated into an adhesive. The adhesive can be used as a component in an in-vitro diagnostic device to release template molecules or to capture target molecules in vacated receptor sites in the synthetic polymer.

  • Patent number: 7745650
    Abstract: The present invention relates to taxane analogs for the treatment of cancer having the general formula: wherein R1 and R2 are each selected from H, an alkyl group, an olefinic group, an aromatic group, an O-alkyl group, an O-olefinic group, or an O-aromatic group; R3 is hydroxyl or OP1; R4 and R5 are each hydroxyl or R7COO; R6 is hydroxyl, OP2, R7COO, or an ether functionality; R7 is an alkyl group, an olefinic group, or an aromatic group; P1 and P2 are each hydroxyl protecting groups; R8 and R9 are each selected from H, alkyl group, olefinic or aromatic group. The present invention is also directed to production methods and intermediates useful in the formation of these new taxane analogs. The methods may begin with a starting compound, such as paclitaxel or docetaxel, which is converted into a taxane analog through various intermediate compounds.
