  Nineteen bisthiazoles were tested in order to assess their anti-inflammatory and antioxidant properties. First, we evaluated the in vitro direct antioxidant capacity of the bisthiazoles using the DPPH radical scavenging method. Then, the anti-inflammatory effect was tested in acute rat experimental inflammation by measuring the acute phase bone marrow response, the phagocytic capacity and the serum nitro-oxidative stress status. Although none of the substances showed significant direct antioxidant potential in the DPPH assay, most of them improved serum oxidative status, when administered to rats with inflammation. Four of the bisthiazoles proved to have good anti-inflammatory properties, similar or superior to that of equal doses meloxicam.

  测试了19种双硫杂环烷以评估其抗炎和抗氧化特性。首先，我们使用DPPH自由基清除法评估了双硫杂环烷的体外直接抗氧化能力。然后，通过测量急性期骨髓反应、吞噬能力和血清氮-氧化应激状态，在急性大鼠实验性炎症中测试了其抗炎效果。尽管在DPPH实验中没有任何物质显示出明显的直接抗氧化潜力，但在给予患有炎症的大鼠时，大多数双硫杂环烷改善了血清氧化状态。其中四种双硫杂环烷显示出良好的抗炎特性，与同等剂量的美洛昔康相似或更优。

  A new series of thiazolidine-2,4-diones was obtained by replacing the ether function of englitazone with various functional groups, i.e., a ketone, alcohol, or olefin moiety. These compounds lower blood glucose levels in the genetically obese and insulin-resistant ob/ob mouse. Appending an oxazole-based group at the terminus of the chain provided highly potent compounds.
