摘要
本文报道用氚一胸腺嘧啶核苷（＾３Ｈ－ＴｄＲ）掺入法研究了新型抗癌药－硒化亚油酸及硒化亚麻酸对小鼠Ｓ１８０细胞ＤＮＡ合成的影响。结果表明，这两种新型抗肿瘤药物能明显抑制＾３Ｈ－ＴｄＲ掺入肿瘤细胞，在１００μｇ／ｍｌ的浓度下，它们对Ｓ１８０瘤细胞ＤＮＡ合成的抑制率分别达到８９．０％和８８．３％，这些结果表明硒化亚油酸及硒化亚麻酸的抗癌机理之一是它们对＾３Ｈ－ＴｄＲ掺入肿瘤细胞的干扰。
The effect of two kinds of new antitumor agents( linoleic acid containing selenium and linolenic acid containing selenium) on the DNA synthesis of Siso tumor cells in vitro were investigated with method of 3H- TdR incorporation. The results showed that these two kinds of new agents can obviously inhibit the incorporation of 3H-TdR into S180tumor cells. At the concentration of 100 ug/ ml, their inhibition retes were 89.0% for lenoleic acid containing selenium and 88 .3% for linolenic acid containing selenium .These results indicated that the possible antitumor mechanism of these two agents is that they can inhibit the incorporation of 3H-TdR into tumor cells and hence inhibit the DNA synthesis of the tumor cells.
