Severe inflammatory reaction can in- jury the body. Thereflore, retarding synthesis of PAF, increasing catabolism of PAF or blocking the combination of PAF and its re- ceptor might be the appropriate treatment. Hitherto, antagonists of PAF have been studied extensively. More than a hundred of such antagonists have been reported, some of them having even been used in clinic and having presented an optimistical prospects, especially natural antagonists BN series and kadsurenone, which have shown sound effects in both basic and clinical experiments.

因此通过阻止PAF合成，增加PAF分解和阻止PAF与其受体结合发挥生物效应可以作为一种适宜的治疗手段，PAF受体拮抗剂研究已成为热点，天然及人工合成的PAF拮抗剂种类很多，已报道有一百种以上，有些已进入临床应用，具有较好的前景，尤其是天然拮抗剂BN系列（以BN52021为代表）及海风藤酮巳在基础及临床研究中取得了可喜成果。

Over the past decades, various efficient methods based on organometallic homogeneous catalysts have been developed.
