摘要:
We designed and prepared the new C-60 fullerene hybrids bearing a xanthine moiety as potential double-action anti-inflammatory agents, capable of simultaneous inhibition of LPS-induced NO and TNF-alpha production. The 10 mu M of fulleropyrrolidine-xanthine dyad 2a and b were effective in suppressing LPS-induced NO production by 55.1 +/- 2.1% and 58.6 +/- 2.6%, respectively, but only 2b was also effectively in suppressing LPS-induced TNF-alpha production by 34.0 +/- 2.7%. We believed that the agents synthesized herein would hold promise for future development of a new generation of potent anti-inflammatory agents. (C) 2007 Published by Elsevier Ltd.
