Title:
CYCLODEXTRIN INCLUSIONS COMPLEXES OF PYRIMIDINE-2,4,6-TRIONES
Document Type and Number:
WIPO Patent Application WO2005097058
Kind Code:
A3
Abstract:
It was surprisingly found that a-trioxopyrimidine-cyclodextrin-complex formed of a trioxopyrimidine derivative represented by the below-described formula (I) and a water-soluble cyclodextrin (further abbreviated as CD) exhibits enhanced water solubility, excellent stability, and low topical stimulation and is useful as a therapeutic agent. Accordingly, the present invention provides a trioxopyrimidine-cyclodextrin complex formed of a trioxopyrimidine derivative or a salt thereof and a cyclodextrin, preferably a-, ß- or ?-cyclodextrin or a water-soluble cyclodextrin derivative (water-soluble being defined as a solubility of at least 0.5 gr/100ml water at 25°C), wherein the trioxopyrimidine derivative is represented by formula (I). It was furthermore found that such a trioxopyrimidine complex with cyclodextrin and an adjuvant such as L-lysine or L-arginine show improved water solubility and bioavailability, excellent stability, and low topical stimulation and is useful as a therapeutic agent.
