  • Publication number: 20210179623
    Abstract: The invention relates to a novel chemical compound characterized in that it contains the active enantiomer S-(?) ketorolac tromethamine combined with other pharmaceutically acceptable adjuvants or excipients, said compound being advantageous over other NSAIDs and, in particular, the known active principle ketorolac tromethamine, comprising a single isomer that is pure and has a better therapeutic index, retaining its therapeutic activity by improving its physicochemical properties, such as solubility or stability, which translates into a decrease in the dose administered, reducing direct gastrointestinal side effects and the time required for the development of the desired therapeutic action. The invention is suitable for use as a medication for the treatment of pain of moderate to high intensity and can be administered in any form in the dose range from 0.5 milligrams to 30 milligrams.

  • Patent number: 7645569
    Abstract: Specific binding of a foreign core ligand to a PAS domain, wherein the PAS domain is predetermined, prefolded in its native state, and comprises a hydrophobic core that has no NMR-apparent a priori formed ligand cavity, is determined using NMR spectra of the PAS domain in the presence and absence of a foreign ligand bound within the hydrophobic core. A functional surface binding specificity of a PAS domain is changed by (a) introducing into the hydrophobic core of the PAS domain a foreign ligand of the PAS domain; and (b) detecting a change in the functional surface binding specificity of the PAS domain.

  • Patent number: 7132278
    Abstract: The invention provides methods and compositions relating to a novel kinase designated PAS Kinase (PASK). The compositions include isolated polypeptides comprising a native PASK protein or a PASK N-terminal domain and polypeptides consisting of a PASK PAS-A or PAS-B domain, as well as isolated polynucleotides encoding such polypeptides, and expression vectors and cells comprising such polynucleotides. The methods include binding assays comprising the steps of incubating a mixture comprising a subject polypeptide with a ligand under conditions wherein the polypeptide binds the ligand; and detecting binding of the polypeptide to the ligand.

  • Publication number: 20050074846
    Abstract: Specific binding of a foreign core ligand to a PAS domain, wherein the PAS domain is predetermined, prefolded in its native state, and comprises a hydrophobic core that has no NMR-apparent a priori formed ligand cavity, is determined by (a) detecting a first NMR spectrum of the PAS domain in the presence of a foreign ligand; and (b) comparing the first NMR spectrum with a second NMR spectrum of the PAS domain in the absence of the ligand to infer the presence the ligand specifically bound within the hydrophobic core of the PAS domain. A functional surface binding specificity of a PAS domain, wherein the PAS domain is predetermined, prefolded in its native state, and comprises a hydrophobic core that has no NMR-apparent a priori formed ligand cavity, is changed by (a) introducing into the hydrophobic core of the PAS domain a foreign ligand of the PAS domain; and (b) detecting a change in the functional surface binding specificity of the PAS domain.
