The present invention provides compositions and methods for screening of compounds that decrease the activity of thymidylate synthase either directly or indirectly. The composition of the invention comprises a DNA construct comprising from the 5′ to the 3′ direction, a TBE cassette comprising one or more copies, in forward or reverse orientation, of TBE1 and TBE2, and a reporter gene operably linked to a promoter and optionally a selectable marker. The method of the invention comprises growing cells comprising the construct of the invention in the presence or absence of a test compound such that a test compound which decreases the activity of
本发明提供了用于筛选直接或间接降低胸苷酸合成酶活性的化合物的组合物和方法。本发明的组合物由 DNA 构建物组成,该 DNA 构建物包括从 5′到 3′方向的 TBE 盒,该 TBE 盒包括一个或多个正向或反向的 TBE1 和 TBE2 拷贝,以及与启动子可操作连接的报告基因和可选择的标记。本发明的方法包括在存在或不存在试验化合物的情况下培养含有本发明构建体的细胞,使试验化合物能降低TBE1和TBE2的活性。
