    • Antisene oligonucleotides targeted to sequences in thymidylate synthase (TS) mRNA. In particular the invention relates to antisense oligonucleotides targeted to sequences in the 3′ end of TS mRNA, which are both cytostatic on their own when administered to human tumour cell lines, and which also enhance the toxicity of anticancer drugs such as Tomudex. The invention also relates to antisense oligonucleotides targeted to sequences at or near the translation start site at the 5′ end of TS mRNA which induce TS gene transcription and enhance cell growth. The invention further relates to a combination product comprising an antisense oligonucleotide in combination with an anticancer agent such as Tomudex (N-(5[N-3,4-dihydro-2-methyl-4-oxoquinazolin-6-ylmethyl)-N-methylamino]-2-thenoyl)-L-glutamic acid) or the Zeneca development compound ZD 9331 ((S)-2-(2-fluoro-4-[N-(4-hydroxy-2,7-dimethylquinazolin-6-ylmethyl)-N-(prop-2-ynyl)amino] benzamido-4-(1H-1,2,3,4-tetrazol-5-yl) butyric acid), and to the use of such a combination product in the treatment of cancer.
    • 靶向胸苷酸合酶(TS)mRNA序列的反义寡核苷酸。 特别地,本发明涉及靶向TS mRNA的3'端的序列的反义寡核苷酸,当被给予人肿瘤细胞系时它们本身都是细胞抑制的,并且还增强抗肿瘤药物如Tomudex的毒性。 本发明还涉及针对诱导TS基因转录并增强细胞生长的TS mRNA的5'末端的翻译起始位点处或附近的序列的反义寡核苷酸。 本发明还涉及包含反义寡核苷酸与抗癌剂如Tomudex(N-(5-N,3,4-二氢-2-甲基-4-氧代喹唑啉-6-基甲基)-N- 甲基氨基] -2-噻吩甲酰基)-L-谷氨酸)或Zeneca显影化合物ZD 9331((S)-2-(2-氟-4- [N-(4-羟基-2,7-二甲基喹唑啉-6-基) 吡啶-2-基甲基)-N-(丙-2-炔基)氨基]苯甲酰氨基-4-(1H-1,2,3,4-四唑-5-基)丁酸),以及这种组合产物在 治疗癌症。
