A series of imidazo[1,2-a]pyrimidine derivatives substituted adjacently with two aryls at positions 2 and 3 were designed and synthesized in order to improve their anti-inflammatory activities. Biological tests suggested that these compounds have antiinflammatory activities with COX-2 selectivity to some extent.

A series of novel nitric oxide-donating derivatives (7a-e, 8a-e) were synthesized by coupling furoxan and nitric oxide with irbesartan analogue and their cytotoxicity against BEL7402 cells in vitro were evaluated by MTT method. It was found that 8c exhibits the most cytotoxic activities with ICso value of 12.5 μmol/L. The hybrids of AT1 antagonist and nitric oxide donor appear to have beneficial effects on antitumor.
