STAT3 is a promising molecular target for the design of new anticancer drugs. In this paper, we report the design and synthesis of a conformationally constrained macrocyclic peptidomimetic 2 via click chemistry. Compound 2 was determined to bind to STAT3 with a K(i) value of 7.3 microM in a competitive fluorescence-polarization-based binding assay, representing a promising initial lead compound for further optimization.
信号转导和转录激活因子3（STAT3）是新型抗癌药物设计中一个很有前景的分子靶点。在本文中，我们报道了通过点击化学设计并合成构象受限的大环肽模拟物2。在基于竞争性荧光偏振的结合试验中，化合物2与STAT3结合的抑制常数（K(i)）值为7.3微摩尔，这表明它是一个有前景的初始先导化合物，可用于进一步优化。
