  Pyrazolopyrimidine-2,4-dione Sulfonamides:  Novel and Selective Calcitonin Inducers

  摘要：

  A. series of py-razolo[4,3-d]pyrimidine sulfonamides and pyrazolo[3,4-d]pyrimidine sulfonamides have been synthesized. These compounds increase transcription of a calcitonin-luciferase promoter and production of cellular calcitonin in a calcitonin-secretion/RIA assay with minimized phosphodiesterase type 4 inhibitory activity at 30 muM as compared to structurally related xanthine methylene ketones such as denbufyllene. These two series are notable examples of small molecules that act as CT-inducers, a method to potentially treat bone loss diseases.
