  • Patent number: 5659027
    Abstract: A novel class of pharmaceutically active boronated compounds are provided. The boronated compounds include boronated purine and pyrimidine bases and boronated nucleosides, as well as phosphate esters and oligomers thereof. The compounds are boronated at the ring nitrogen of the purine or pyrimidine base, or at a 2', 3' or 5' amino substituent of the nucleoside sugar.

  • Patent number: 5177198
    Abstract: A process of making oligoribonucleoside and deoxyribonucleoside boranophosphates and salts thereof is disclosed. The process comprises the steps of condensing a ribonucleotide or deoxyribonucleotide with a nucleoside phosphitylating agent, wherein the phosphitylating agent includes a 5' -OH group protected by an acid-labile protecting group and a moiety bonded to the phosphorus atom therein that is a stronger proton acceptor than the 5'-OH group of the ribonucleotide or deoxyribonucleotide to form a reaction intermediate, then oxidizing the reaction intermediate so formed with a compound comprising a Lewis base and a boron-containing substituent, wherein the Lewis base is a weaker electron donor than the phosphite phosphorus of the reaction intermediate, to form a ribonucleotide or deoxyribonucleotide boranophosphate. These steps are repeated on the nucleotide boranophosphate to form an oligonucleotide boranophosphate.
    Type: Grant
