Abstract
The present invention provides new methods for the synthesis of the therapeutic dinucleotide, P1,P4-di(uridine 5′-tetraphosphate), and demonstrates applicability to the production of large quantities. The methods of the present invention substantially reduce the time period required to synthesize diuridine tetraphosphate, preferably to three days or less. The novel tetrammonium and tetrasodium salts of P1,P4-di(uridine 5′-tetraphosphate) (Formula I) prepared by these methods are stable, soluble, nontoxic, and easy to handle during manufacture. Therapeutic uses of Formula I include treatment of sinusitis, otitis media, dry eye, retinal detachment, nasolacrimal duct obstruction, female infertility and irritation due to vaginal dryness, via increased mucus secretions and hydration of the epithelial surface.
wherein:
X is Na, NH4 or H, provided that all X groups are not H.
