Nucleic Acid Related Compounds. 82. Conversions of Adenosine to Inosine 5′-Thioether Derivatives withAspergillus oryzaeAdenosine Deaminase or Alkyl Nitrites. Substrate and Inhibitory Activities of Inosine 5′-Thioether Derivatives with Purine Nucleoside Phosphorylase
摘要:
Adenosine derivatives lacking a 5'-hydroxyl group seldom act as alternative substrates of adenosine deaminases from calf intestine and other mammalian sources. A deaminase from Aspergillus oryzae deaminated adenosine 5'-thioether derivatives cleanly and more efficiently than alkyl nitrites. The inosine derivatives were very poor alternative substrates and weak inhibitors of purine nucleoside phosphorylase.
4-Halo-1-naphthol is reacted with a secondary amine and formaldehyde to produce a reaction mixture containing a Mannich base which is hydrogenated to produce 2-methyl-1-naphthol. Advantageously, the procedure can be carried out in one pot.
