acid analogues has been synthesized and evaluated as inhibitors of leukotriene B(4) (LTB(4)) biosynthesis and as antiproliferative agents. The 4-O-benzylated and the 4-O-demethylated congeners were the most potent inhibitors of LTB(4) production of the depside class of compounds, with IC(50) values in the submicromolar range. Furthermore, these compounds do not function as redox-based inhibitors because
已合成了一系列的tus酸类似物,并被评估为白三烯B(4)(LTB(4))生物合成的抑制剂和抗增殖剂。4-O-苄基化和4-O-去甲基化同类物是最有效的Lpp(4)产生的深度类化合物的抑制剂,IC(50)值在亚微摩尔范围内。此外,这些化合物不能用作基于氧化还原的抑制剂,因为它们对稳定的自由基2,2,2-二苯基-1-吡啶并肼基不具有反应性,并且不产生可观量的脱氧核糖降解(作为衡量其生成潜力的量度)羟基自由基。一些钝化酸同源物也是角质形成细胞生长的有效抑制剂。生长抑制不是通过破坏细胞膜来介导的,
