ＦＴＹ72 0 (以下简称ＦＴＹ ) ,是来自冬虫夏草抽提物的一种新合成的免疫抑制剂[1 ] 。ＦＴＹ与目前最常用的免疫抑制剂环孢素 (ＣｓＡ )有不同的药理作用。当在体外刺激大鼠脾细胞时 ,1 0 0 0ｎｍｏｌ/Ｌ的ＦＴＹ对ＩＬ 2的产生没有抑制作用 ,而这一浓度的ＣｓＡ已经可以完全
FTY72 0 (hereinafter referred to as FTY) is a newly synthesized immunosuppressant from Cordyceps sinensis extract [1]. FTY has different pharmacological effects from the most commonly used immunosuppressant cyclosporine (CsA). When rat spleen cells were stimulated in vitro, 1 000nmol/L of FTY had no inhibitory effect on the production of IL 2, and this concentration of CsA was already complete.
