    摘要: Storage stable reduced nicotinamide-adenine-dinucleotide (NADH) compositions, which do not form dehydrogenase inhibitors of prolonged time periods, are produced by forming a dilute aqueous solution of inhibitor-free NADH and maintaining this solution in a thin layer vacuum.

    摘要: NUCLEOSIDE DIPHOSPHATE AND ITS ESTERS ARE PREPARED IN GOOD YIELD, WITH SHORT REACTION TIMES AND WITHOUT SUBSTANTIAL FORMATION OF BY-PRODUCTS, BY REACTING (A) A NUCLEOSIDE MONOPHOSPHATE AMIDATE COMPOUND OF THE FORMULA:

    X-O-PO2-1-AM

    IN WHICH X IS NUCLEOSIDE RESIDUE, AND AM IS A RADICAL OF THE FORMULA:

    -N(-R1)-R2

    WHEREIN R1 AND R2, WHICH CAN BE THE SAME OR DIFFERENT ARE HYDROGEN ATOMS OR ALKYL RADICALS CONTAINING UP TO 4 CARBON ATOMS OR WHEREIN R1 AND R2, TOGETHER WITH THE NITROGEN ATOM TO WHICH THEY ARE ATTACHED, FORM A HETEROCYCLIC RING, WHICH CAN CONTAIN A FURTHER HETEROATOM; (B) A PHOSPHORIC ACID COMPOUND OF THE FORMULA:

    O3P2- -O-R

    IN WHICH R IS HYDROGEN ATOM OR THE RESIDUE OF A HYDROXYL GROUP-CONTAINING ORGANIC COMPOUND; IN AN ALIPHATIC ALCOHOL OF FROM 1 TO 4 CARBON ATOMS OR IN A DIALKYL KETONE OF FROM 1 TO 3 CARBON ATOMS PER ALKYL GROUP OR IN DIMETHYL FORMAMIDE, AT A PH OF FROM ABOUT 1 TO 6.5.
