      Selective secreted phospholipase A2 (sPLA2) inhibitor Tocris Bioscience 5313
      Selective secreted phospholipase A2 (sPLA2) inhibitor (IC50 = 50 - 750 nM for a range of sPLA2 isoforms). Has no effect on cytosolic PLA2 or COX-1 and COX-2 activity. Attenuates sPLA2-induced thrombox ane formation in bronchoalveolar lavage (BAL) cells. Also suppresses sPLA2-induced contractions of lung pleural strips ex vivo. Orally available.
