  • Patent number: 7041673
    Abstract: The subject invention concerns novel compounds that are useful as ultrashort acting hypnotic barbiturates. Specifically exemplified are derivatives of barbituric and thiobarbituric acids. They are rapidly metabolized by blood and tissue enzymes to form polar metabolites with no hypnotic activity and which are rapidly eliminated.

  • Patent number: 7037933
    Abstract: The subject invention pertains to novel compounds (and salts thereof), and compositions comprising the compounds, for the treatment of cardiac arrhythmias. The subject invention further concerns methods of making the novel compounds. The novel compounds are rapidly metabolized analogs of amiodarone, having the distinct and advantageous characteristic of being metabolized to a less lipophilic compound. This results in an improved safety profile. The new compounds have particular utility for treating life-threatening ventricular tachyarrhythmias, especially in patients with congestive heart failure (CHF). The compounds also provide effective management for ventricular arrhythmias and supraventricular arrhythmias, including atrial fibrillation and re-entrant tachyarrhythmias involving accessory pathways.

  • Patent number: 7022722
    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, thiazolidinedione analogs that 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 that have been designed to be metabolized by serum or intracellular hydrolases and esterases. Pharmaceutical compositions of the ester-containing thiazolidinedione analogs are also taught.
