It is reported that alkannin and shikonin isolated from the roots of Lithospermum erthyrorhizon or Alkanna tinctoria and their acylshikonin derivatives are potent selective inhibitors of DNA Topoisomerase Ⅰ.

文献报导紫草素和酰基紫草素等具有DNA拓扑异构酶Ⅰ的选择性抑制活性。本组曾合成得到少量环异紫草素（8），它对小鼠白血病P-388肿瘤细胞具有强烈的抑制作用。

In this paper, we mainly study the alternating group A_4 actions on spin 4-manifolds. First we discuss the special action of A_4 on K3 surfaces of Fermat type, we compute the fixed points set of this action and some invariants of the group action, also we get some topological properties. Then we study the A_4 actions on general K3 surfaces and obtain some similar results.

本文主要是以交错群A_4在K3曲面上的作用为研究对象，从Fermat型K3曲面上的特殊的A_4作用出发，得到了Fermat型K3曲面上A_4作用的不动点，利用不动点集计算了群作用的一些不变量并得到了相关的拓扑性质，在此基础上进一步把其中的一些结果推广到一般情形下的同伦K3曲面上。
