Anti-neuroinflammatory activity of 1,5-benzodiazepine derivatives
摘要:
A series of 2,3-dihydro-1,5-benzodiazepines were synthesized and evaluated for anti-inflammatory effects in microglia cells. Among the 1,5-benzodiazepines tested, compound 3e strongly inhibited LPS-induced nitric oxide ( NO) production, with an IC50 value of 7.0 mu M in the microglia cells. Also, compound 3e significantly inhibited the enzymatic activity of inducible NO synthase ( iNOS) without changes in iNOS protein expression or NO scavenging activity. This result suggests that compound 3e showed anti-neuroinflammatory effects by suppressing iNOS enzyme activity. (C) 2010 Elsevier Ltd. All rights reserved.
