Patents by Inventor Gerald Sigler

Gerald Sigler has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20060088933
    Abstract: The invention provides derivatives of efavirenz and methods of making derivatives of efavirenz. The derivatives include immunogenic compounds for producing antibodies to efavirenz and labeled efavirenz tracers. These compounds are useful in immunoassay methods for determining efavirenz.

  • Publication number: 20060040257
    Abstract: A non-isotopic immunoassay for an HIV protease inhibitor comprising incubating a sample containing the inhibitor with a receptor specific for the inhibitor or for a metabolite of said inhibitor and further with a conjugate comprising an analog of the inhibitor and a non-isotopic signal generating moiety. Signal generated as a result of binding of the inhibitor by the receptor is measured and correlated with the presence or amount of protease inhibitor in the original sample.

  • Publication number: 20050153439
    Abstract: The present invention comprises novel analogs of ecstasy-class compounds and novel ecstasy-class immunogens leashed out of, i.e., derived from, the methylenedioxy position. The invention also comprises unique monoclonal antibodies generated using MDO-leashed MDMA immunogens as well as unique conjugates and tracers. These antibodies, conjugates, and tracers are useful in immunoassays for the detection of ecstasy-class compounds in biological fluids.

  • Publication number: 20050148596
    Abstract: Derivatives and conjugates of indinavir for generation of antibodies and labeled conjugates for use for detection of indinavir in biological samples. The derivatives are synthesized out of the indane ring hydroxyl group or the pyridine ring nitrogen of indinavir. Also disclosed is synthesis of a major metabolite of indinavir (M6) in a single step from indinavir using palladium catalyst and hydrogen gas. Indinavir M6 has been extended to synthesize various analogs of indinavir with suitable functional groups. These derivatives are useful in the development of indinavir immunogens, antibodies, and labeled conjugates in the development of indinavir immunoassays.

  • Publication number: 20050009076
    Abstract: The present invention provides a method for the measurement of an analyte in biological samples whereby an uncompetitive inhibitor is coupled to a ligand and utilized in a homogeneous assay. The analyte can be a drug or drug derivative, hormone, polypeptide, or oligonucleotide. The present invention also provides novel compounds, assay reagents and packaged kits useful for performing such measurements.
