  Synthesis of 4-amino/hydroxy-6-methylthio-12-(2′,2′-diethoxyethyl)-1H/2H-pyrazolo[3,4-d]pyrimidines and their antiallergic activity

  摘要：

  The synthesis of a series of 4-amino/hydroxy-6-substituted- 1/2-(2',2'-diethoxyethyl)-1H/2H-pyrazolo[3,4-d]pyrimidines by alkylation of substituted pyrazolo[3,4-d]pyrimidines has been described, and their antiallergic activity evaluated in mice. The 2 most active compounds 4b and 5b were also tested in the rat. The most active compound 4b showed non-significant antihistaminic or antiserotoninergic activity.

  Proton NMR analysis on newly synthesized 1,2-bis(4,6-diethylthio-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethane, 2c, and 1,2-bis(4,6-diethylthio-1H-pyazolo[3,4-d]pyrimidin-1-yl)propane, 2d. showed intramolecular stacking in solution. X-Ray crystallography on 2c and 2d. however, confirmed the presence of such intramolecular stacking only in case of the 'propylene linker' compound. 2d. while the 'ethylene linker' compound. 2c. was devoid of it.
