  New Selective Phosphodiesterase 4D Inhibitors Differently Acting on Long, Short, and Supershort Isoforms

  摘要：

  The lack of selective inhibitors toward the long, short, or supershort phosphodiesterases (PDE4s) prevented researchers from carefully defining the connection between different enzyme isoforms, their brain localization, and their role in neurodegenerative diseases such as Alzheimer's disease (AD). In the search for new therapeutic agents for treating memory and learning disorders, we synthesized new rolipram related PDE4 inhibitors, which had sonic selectivity toward the long form PDE4D3. The first series was synthesized as racemate and then resolved by semipreparative HPLC on chiral supports. Herein we report the synthetic pathways to obtain compounds 1a-c, 2a-c, 3a-c, 4a-f, 5a,b, 6a,b, 7a,b, the chiral analytical study to resolve compounds la-c, 2a-c, 3a-c, the molecular docking Study for compound 1c, and the biological results and sonic SAR considerations that provide sonic insights and hints for the structural requirements for PDE4D Subtype selectivity and enzyme inhibition.

• Magnesium Meerwein−Ponndorf−Verley−Oppenauer Reaction. The Origin of an Impurity in PDA-641 Batches

  日期：1998.11.1

  An impurity in the initial scale-up batch of PDA-641 was identified and the pathway of its formation was established. The precursor of the impurity was formed by magnesium Meerwein-Ponndorf-Verley-Oppenauer reaction during the Grignard addition step. As a result of the investigation, the level of the impurity could be reduced 6-fold in the subsequent batch.
