Abstract

The synthesis of twenty nine novel derivatives of pyrazolo[3,4-d]pyrimidines as non acidic nonsteroidal anti-inflammatory drugs has been achieved via reaction of 4-chloro-1-phenylpyrazolo[3,4-d]pyrimidine with different substituents including 4-amino-3-methylphenol, 4-phenylene diamine and 4-acetamidophenol.The anti-inflammatory activity of thirteen representative compounds have been screened compared to indomethacin as a reference drug. The results revealed that all the tested compounds showed anti-inflammatory activity with the exception of 10a.
