The present invention relates to amino acid salts of nicotinic acid ribosides and compositions thereof of Formula I, useful in the treatment of disorders and diseases associated with deficiencies in NAD+:wherein M1, R1, R2, and R3 are as described herein.

The invention discloses a preparation method of a nucleotide monomer, which comprises the following steps: taking methyl-D-ribofuranoside as an initial raw material, and finally realizing the synthesis of a compound monomer as shown in a formula P through the steps of selective protection, selective deprotection, C-C bond construction, acylating chlorination reaction, basic group introduction through glycosylation, deprotection, hydroboration oxidation and ring closing in sequence. By providing a brand new synthesis method, the reaction yield is improved, the cost of the whole synthesis molecule is reduced, the binding affinity of the prepared target nucleoside monomer serving as a reported drug applied to HCV resistance to RNA can be improved so as to further improve nuclease resistance, and the method has great significance for subsequent nucleic acid drug research.

The invention discloses a phenyl riboside compound as well as an extraction method and application thereof, and belongs to the technical field of agricultural herbicides. The compound is prepared from a plant endophytic fungus Neofusicoccum parvum LZUC-S1 through the steps of fermentation, ethyl acetate extraction and multiple chromatographic separation and purification. The compound is novel in structure and comprises seven phenyl riboside derivatives with different substituent changes. Experiments show that the compound disclosed by the invention has a remarkable inhibition effect on common field weeds such as chloris virgata, quinoa and purslane: under the concentration of 100 mg / L, the root length inhibition rates of the three weeds respectively reach 99.6%, 86.4% and 99.8%, and the bud length inhibition rates of the three weeds respectively reach 81.6%, 76.8% and 97.2%. In addition, the series of compounds have the characteristics of high efficiency, low toxicity and easiness in degradation, and can be applied to the field of green agriculture as a microbial herbicide.

Compositions and methods of treatment for osteoarthritis and cartilage damage in a subject comprising administering to a subject in need thereof an effective amount of a nicotinamide-riboside (NR) and pterostilbene (PT) in a ratio of about 2:1.

The invention provides a compound growth regulator for promoting seedling emergence and ear strengthening of ratooning rice in the regeneration season and a preparation method and application thereof.The compound growth regulator is prepared from zeatin riboside, monopotassium phosphate, a surfactant and an alkaline solution, the zeatin riboside is dissolved in the alkaline solution, a proper amount of water is added to reach the target concentration, then the monopotassium phosphate is added to be dissolved, and the surfactant is added; adding a surfactant into the solution, and uniformly mixing; the compound growth regulator is sprayed once three days before ratooning rice is harvested in the first season and one day after the ratooning rice is harvested in the first season; the dosage of the compound growth regulator is 30-50 L / mu; the riboside zeatin and the monopotassium phosphate are used as the compound growth regulator of the ratooning rice, so that the ear number per unit area, the maturing rate and the yield in the ratooning season can be remarkably increased, and the effect is remarkably superior to that of singly applying the riboside zeatin or the monopotassium phosphate; the technical problems of insufficient field ear number and low yield of ratooning rice in the ratooning season can be solved, and the method has good application value.

The invention discloses a preparation method of 3 '-propenyloxy furan ribonucleoside. The preparation method comprises the following steps: (1) protecting ribonucleoside by using tert-butyldimethylsilyl chloride; (2) carrying out complexing on the ribofuranoside protected by tert-butyldimethylsilyl chloride by using dioctyl tin oxide, so as to obtain a TBS-ribofuranoside-tin complex; (3) adding allyl methyl carbonate and tetrakis (triphenylphosphine) palladium into the TBS-ribonucleoside-tin complex for coupling, so as to obtain a coupling compound; 4, tetrabutylammonium fluoride is added into the coupling compound, a TBS protecting group is removed through a reaction, separation and purification are conducted, and the 3 '-propenyloxy ribofuranoside is obtained.According to the method, the 3'-propenyloxy ribofuranoside can be obtained only through one-time separation by adopting a three-step one-pot method, and industrial mass production is facilitated.
