A new series of pyrazolidine derivatives was synthesized and evaluated for their ability to inhibitdipeptidylpeptidaseIV (DP-IV). Compound 9i was the most active in this series, exhibited IC50 value of 1.56 microM and ED50 value of 80 mg/kg (in vivo DP-IV inhibition; po).
Fluorine-containing aromatic diamines have been synthesized as monomers for an investigation of polyimides of low dielectric constant. For most compounds, the synthetic route has been based on nucleophilic aromatic substitution of alcohols and phenols, on appropriate aromatic nitro compounds, and subsequent hydrogenation of the dinitro compounds obtained. The separation and purification of products
