    • This invention relates to a novel class of 4,5,6,7-substituted non-nucleoside, non-phosphorylatable pyrrolo[2,3-d]pyrimidines which exhibit both significantly lower levels of cytotoxicity and superior antiviral activity than known nucleoside, non-nucleoside, and non-nucleoside, non-phosphorylatable pyrrolo[2,3-d]pyrimidine derivatives, particularly against human DNA viruses such as cytomegalovirus (HCMV) and herpes simplex virus type 1 (HSV-1). These compounds are represented by formula (I) wherein R is -NH2 or -NHCH3; R is -CN, -CSNH2, or -CSeNH2; R is -H or -NH2; and R is selected from the group consisting of aryls and aralkyls having 6 to 30 carbon atoms; aliphatic oxy-hydrocarbyls having 2 to 15 carbon atoms, lacking free hydroxyl groups and further lacking acyl or acyl derivatized groups; and oxy-hydrocarbyls having 6 to 30 carbon atoms, at least one aryl or aralkyl group, and only one oxy-group; with the proviso that if R is -CN and R is -H, then R is -NH2 and R is -CH2C6H4-2-CH3.
    • 本发明涉及一类新颖的4,5,6,7-取代的非核苷,不可磷酸化的吡咯并[2,3-d]嘧啶,其显示出比已知的核苷非特异性的显着更低的细胞毒性水平和更好的抗病毒活性 核苷和非核苷,不可磷酸化的吡咯并[2,3-d]嘧啶衍生物,特别是针对人DNA病毒如巨细胞病毒(HCMV)和1型单纯疱疹病毒(HSV-1)。 这些化合物由式(I)表示,其中R 4是-NH 2或-NHCH 3; R 5是-CN,-CSNH 2或-CSeNH 2; R 6是-H或-NH 2; R 7选自具有6〜30个碳原子的芳基和芳烷基; 具有2至15个碳原子的脂族烃基,缺少游离羟基并进一步缺乏酰基或酰基衍生基团; 和具有6至30个碳原子的烃基,至少一个芳基或芳烷基和仅一个氧基; 条件是如果R 5是-CN且R 6是-H,那么R 4是-NH 2,R 7是-CH 2 C 6 H 4 -2-CH 3。

    • The invention is directed to methods of reducing the viability of a proliferating mammalian cells such as cancer cells. In one method cells deficient in p53 activity and in p53 suppressor activity of one or more p53-interacting regulatory proteins cell viability is reduced by increasing the level or activity of p53 in the cell. In another method viability of cells exhibiting p53 activity and p53 suppressor activity of one or more p53-interacting regulatory proteins is reduced by reducing the suppressor activity of the one or more p53-interacting regulatory proteins. Further, cell viability is reduced in cells deficient in p53 activity and exhibiting p53 suppressor activity of one or more p53-interacting regulatory proteins by a method that includes: (a) increasing the level or activity of p53 in the cell, and (b) reducing the suppressor activity of the one or more p53-interacting regulatory proteins. Also, included are methods of selectively reducing the viability of proliferating cancer cells compared to nonproliferating normal cells within a mixed population of cells and to methods of selectively reducing the viability of chronic granulocytic leukemia cells within a sample of proliferating bone marrow cells.
    • 本发明涉及减少增殖的哺乳动物细胞如癌细胞的活力的方法。 在一种方法中,一种或多种p53相互作用的调节蛋白的p53活性和p53抑制活性缺乏的细胞通过增加细胞中p53的水平或活性来降低细胞活力。 在另一种方法中,通过降低一种或多种p53相互作用的调节蛋白的抑制活性来降低表现出一种或多种p53相互作用调节蛋白的p53活性和p53抑制活性的细胞的存活力。 此外,通过包括以下方法的一种或多种p53相互作用的调节蛋白的p53抑制活性表现出p53活性缺陷的细胞的细胞活力降低,(a)增加细胞中p53的水平或活性,(b) 降低一种或多种p53相互作用的调节蛋白的抑制活性。 此外,包括与混合细胞群体内的非增殖性正常细胞相比选择性降低增殖性癌细胞的存活力的方法以及选择性降低增殖性骨髓细胞样品内慢性粒细胞白血病细胞活力的方法。
