Method for large-scale production of di(uridine 5′-tetraphosphate) and salts thereof

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, wherein: X is Na, NH4 or H, provided that all X groups are not H.
