Patents by Inventor Robert Strongin

Robert Strongin 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).

  • Patent number: 9952231
    Abstract: Embodiments of methods and compounds for isolating and detecting lysophosphatidic acids (LPAs) are disclosed. Kits for performing the methods also are disclosed. LPAs are isolated from biological samples by liquid-liquid extraction followed by solid phase extraction. LPA species may be separated by HPLC, and the separated species may be identified and quantified. Also disclosed are embodiments of compounds capable of universally detecting a plurality of LPA species with substantially equivalent sensitivity. Embodiments of the disclosed compounds are useful for determination of total LPA concentration in a sample comprising a plurality of LPA species without separation of individual LPA species.

  • Patent number: 9709572
    Abstract: Embodiments of probes for selectively detecting compounds having a thiol group and an amino group, e.g., cysteine and/or homocysteine, are disclosed, along with methods and kits for detecting the compounds in neutral media with the probes. The probes have a structure according to the general formula where R1-R4 independently are hydrogen hydroxyl, halogen, thiol, thioether, lower aliphatic, or lower alkoxy, x is an integer from 0 to 4, and each R5 independently is halogen, hydroxyl, thiol, thioether, lower aliphatic, or lower alkoxy. Embodiments of the disclosed probes are capable of undergoing condensation/cyclization reactions with cysteine and/or homocysteine. Cysteine and/or homocysteine can be selectively detected and identified by determining fluorescence emission of the probes at characteristic wavelengths.

  • Patent number: 8933129
    Abstract: The present teachings provide compounds of Formulae I and II: and pharmaceutically acceptable salts, hydrates, complexes, esters, and prodrugs thereof, wherein R1, R1?, R2, R2?, R3, R3?, and X are as defined herein. The present teachings also provide methods of making the compounds of formulae I and II, and methods of treating RyR-associated conditions, disorders, and diseases that include administering a therapeutically effective amount of a compound of formula I or II to a subject in need thereof. In addition, the present teachings relate to methods of reducing the open probability of a ryanodine receptor, and methods of reducing Ca2+ release across a ryanodine receptor (e.g., into the cytoplasm of a cell), by contacting a compound of formula I or II with a ryanodine receptor.
