  • Patent number: 6887470
    Abstract: A method for protecting a peptide from peptidase activity in vivo, the peptide being composed of between 2 and 50 amino acids and having a C-terminus and an N-terminus and a C-terminus amino acid and an N-terminus amino acid is described. In the first step of the method, the peptide is modified by attaching a reactive group to the C-terminus amino acid, to the N-terminus amino acid, or to an amino acid located between the N-terminus and the C-terminus, such that the modified peptide is capable of forming a covalent bond in vivo with a reactive functionality on a blood component. In the next step, a covalent bond is formed between the reactive group and a reactive functionality on a blood component to form a peptide-blood component conjugate, thereby protecting said peptide from peptidase activity. The final step of the method involves the analyzing of the stability of the peptide-blood component conjugate to assess the protection of the peptide from peptidase activity.

  • Patent number: 6849714
    Abstract: A method of synthesizing a modified therapeutic peptide capable of forming a peptidase-stabilized therapeutic peptide conjugate, the peptide having between 3 and 50 amino acids, is k. In a first step of the method, a therapeutic peptide having a carboxy terminal amino acid and amino terminal amino acid is synthesized. In a second step, pairs of cysteine residues present in the therapeutic peptide are sequentially and selectively oxidized to form disulfide bridges in the therapeutic peptide. In a third step, a protecting group is attached to remaining cysteine residues that do not form disulfide bridges in the therapeutic peptide. Finally, the peptide is coupled to a reactive group capable of reacting with amino groups, hydroxyl groups or thiol groups on a blood component to form a covalent bond therewith.

  • Publication number: 20040254180
    Abstract: The subject invention provides pharmaceutical compounds useful in the treatment of Type II diabetes. These compounds are advantageous because they are readily metabolized by the metabolic drug detoxification systems. Particularly, isoxazolidine compounds which have been designed to include esters within the structure of the compounds are provided. This invention is also drawn to methods of treating disorders, such as diabetes, comprising the administration of therapeutically effective compositions comprising compounds which have been designed to be metabolized by serum or intracellular hydrolases and esterases. Pharmaceutical compositions of the isoxazolidine compounds are also taught.

  • Patent number: 6818782
    Abstract: The subject invention pertains to novel enantiomerically pure compounds, and compositions comprising the compounds, for the treatment of cardiac arrhythmias. The subject invention further concerns a method of making and purifying the compounds. The enantiomerically purified compounds, and compositions of these compounds, exhibit unexpectedly distinct and advantageous characteristics, such as a markedly superior ability to reduce or inhibit ventricular premature beats, as compared to racemic mixtures of the compounds.

  • Patent number: 6610825
    Abstract: Conjugates are prepared from antinociceptive agents, particularly opioids or opioid analogs, more particularly dynorphins, endorphins, deltorphins, enkephalins or analogs thereof, by combining said antinociceptive agent with a material providing a functionally reactive group capable of reacting with a blood component (preferably a blood cell or protein). Said conjugates permit extension of the therapeutic life of the antinociceptive agent. They may be administered to patients to alleviate pain, produce analgesic effects, or assist in cases of narcotics withdrawal, and may also be used as probes for receptor activity. The administration to the patient may be made either in vivo or ex vivo and may be performed by either introducing the derivative including the reactive functional group into the patient's vascular system or preparing such a conjugate externally (or in vitro) and introducing that conjugate to the patient's vascular system.
