  Azodioxides Activated by Electron Acceptors in Geminal or Vicinal Position

  摘要：

  Twenty-two nitroso compounds with cyano, acyloxy, or carbonyl groups in geminal position were prepared, eight of them for the first time. In the solid state these compounds dimerize to colorless azodioxides. Exceptions are the 4-nitrobenzoyloxynitroso compounds 7b, f, and g which form bright blue crystals. In vitro (Born test, collagen) considerable antiplatelet activity was observed in each class of compounds. Azodioxides with cyano groups in geminal position (3a, b) were most active (IC50 approximate to 10 mu M) suggesting the importance of strong electron withdrawing groups in geminal position to the azodioxide partial structure. When administered orally to rats (60 mg/kg) all compounds inhibited the thrombus formation in mesenteric arterioles and venules. The acetyloxy derivatives 5d and 5e were most active (18-21% inhibition in arterioles and 11-15% inhibition in venules). In aqueous media at 37 degrees C the cyanonitroso compound 3b and the benzoyloxynitroso compound 7a decomposed to nitric oxide and its reduced form nitrosohydrogen. This suggests that the above pharmacological effects are mediated by a NO dependent mechanism.
