制备方法与用途

生物活性

Telomestatin 是一种非常有效的端粒酶(telomerase)抑制剂,可以从 Streptomyces anulatus 3533-SV4 中分离得到。它选择性地促进分子内 G-quadruplexes 的形成,特别是人类端粒序列 d[T2AG3]4 的形成。Telomestatin 是一种 ADC 细胞毒素,可用于癌症研究。

靶点
  • 传统细胞毒剂
体外研究

Telomestatin (0-50 μM) 促进或稳定了分子内 G-quadruplex 形成。在 DNA 浓度为 0.005 和 0.2 µM 的情况下,EC₅₀ 值分别为 0.03 µM 和 0.53 µM。对突变寡核苷酸 d[T2AGAG]4 进行的平行实验中,Telomestatin 并未使其转化为 G-quadruplex 结构。

在 10 μM 浓度下,Telomestatin 显著降低了 DN-hTERT 的表达,从而减少了端粒酶活性。此外,在 U937 细胞中,2 μM 浓度时,随着细胞传代数(PD)从 20 增加到 15,末端限制片段 (TRF) 长度从 9.5 kb 逐渐缩短至 3.8 kb。

在正常二倍体人成纤维细胞和 ALT-阳性细胞中,Telomestatin (2-5 μM;短期或长期) 的影响较小。短期暴露于 5 μM Telomestatin(3 天)对正常人类成纤维细胞 BJ 或 IMR-90 细胞的存活率没有显著影响;然而,它降低了 GM847 细胞的存活率。

在更长时间内(10-50 天),Telomestatin (2 μM) 对 BJ 和 IMR-90 细胞的增殖速率和存活率没有明显改变,并且也不改变 GM847 细胞的增殖。

体内研究

通过腹腔注射 Telomestatin(3-15 mg/kg;每周两次;共 4 周)减少了 U937 转移瘤的端粒酶活性并抑制了其生长。系统性给予 3 mg/kg、9 mg/kg 或 15 mg/kg 的 Telomestatin 分别使肿瘤端粒酶活性下降至对照组的 60.2%、74% 和 92.5%。

  • 动物模型
    • 转移瘤模型:小鼠 U937 转移瘤
    • 剂量:3-15 mg/kg
    • 给药方式:腹腔注射;剂量 3-15 mg/kg;每周两次,共 4 周
    • 结果:
      • PBS 治疗 21 天后平均肿瘤体积为 1,395 mm³;
      • Telomestatin 治疗后的平均肿瘤体积为 291 mm³。
      • 未表现出不良反应(体重减轻、临床症状或生存率下降)。
      • 减少了骨髓中的 U937 细胞,并恢复了小鼠的造血功能。

    Total Synthesis of (R)-Telomestatin
    摘要:
    We have achieved a total synthesis of telomestatin, and its absolute configuration was determined to be (R). Coupling of cysteine-containing trisoxazole amine and serine-containing trisoxazole carboxylic acid, followed by macrocyclization, provided a 24-membered diamide. The seventh oxazole ring was formed by a Shin's procedure via dehydroamide. Cyclodehydration of a modified (R)-cysteine-(S-Bu-t) moiety using Kelly's method (PPh3(O)-Tf2O) with anisole furnished (R)-telomestatin, whose CD spectrum was in good agreement with that of the natural product.
