  • Patent number: 8507734
    Abstract: The present invention provides a process for purifying a monoterpene or sesquiterpene having a purity greater than about 98.5% (w/w). The process comprises the steps of derivatizing the monoterpene (or sesquiterpene) to produce a monoterpene (or sesquiterpene) derivative, separating the monoterpene (or sesquiterpene) derivative, and releasing the monoterpene (or sesquiterpene) from the derivative. Also encompassed by the scope of the present invention is a pharmaceutical composition comprising a monoterpene (or sesquiterpene) having a purity greater than about 98.5% (w/w). The purified monoterpene can be used to treat a disease such as cancer. The present monoterpene (or sesquiterpene) may be administered alone, or may be co-administered with radiation or other therapeutic agents, such as chemotherapeutic agents.

  • Patent number: 8491958
    Abstract: An acoustic wave biosensor comprising a surface of a mixed self-assembling monolayer for receiving a probe-biomolecule is described herein. The biosensor surface may comprise a piezoelectric quartz crystal,—for detection purposes with the electromagnetic piezoelectric acoustic sensor (EMPAS)—upon which a mixed self-assembling monolayer is formed, which includes at least one linker, such as 2,2,2-trifluoroethyl-13-trichlorosilyl-tridecanoate (TTTA); its oligoethylene glycol (OEG) analog OEGylated TTTA (OEG-TTTA); S-(2-(2-(2-(3-trichlorosilyl-propyloxy)-ethoxy)-ethoxy)-ethyl)-benzenethiosulfonate (OEG-TUBTS). Linker/diluent systems for attaching a functionalizing entity to the surface of a biosensor are described, as well as methods for preparing a biosensor surface with an oligoethylene glycol linker.

  • Patent number: 8461368
    Abstract: The present invention relates to a process for preparing organic silane compounds having a ?-cyano ester group. In particular, the present invention relates to a process for preparing organic silane compounds having a ?-cyano ester group, in which ?-cyano ?-cyano containing compounds having an unsaturated group are hydrosilylated using a hydro alkoxy silane in the presence of a platinum-vinyl siloxane catalyst. The preparation process according to the present invention can stably initiate and progress the reaction, minimize the generation of by-products, and prepare organic silane compounds having a ?-cyano ester structure with high yield.

    Abstract: A (meth)acrylic-modified organopolysiloxane is prepared by reacting an epoxy-modified organopolysiloxane with (meth)acrylic acid in the presence of a base. A saving of reactant expense is achieved. The (meth)acrylic-modified organopolysiloxane has so high a rate of acrylic introduction that it may be cured with radiation. The cured product exhibits high substrate adhesion and finds use as release liners.
