Synthesis and biological evaluation of novel pyrazole compounds
摘要:
A novel dipyrazole ethandiamide compound and acid chloride of pyrazolo[3,4-d] pyrimidine 4(5H)-one were prepared and reacted with a number of nucleophiles. The resultant novel compounds were tested in several in vitro and in vivo assays. Three compounds inhibited the secretion of neurotoxins by human THP-1 monocytic cells at concentrations that were not toxic to these cells. They also partially inhibited both cyclooxygenase-1 and -2 isoforms. In animal studies, two compounds were notable for their anti-inflammatory activity that was comparable to that of the clinically available cyclooxygenase-2 inhibitor celecoxib. Modeling studies by using the molecular operating environment module showed comparable docking scores for the two enantiomers docked in the active site of cyclooxygenase-2. (C) 2010 Elsevier Ltd.
