  摘要：

  以克级合成小系列的酰基胍和酰基硫脲衍生物，并分析其调节Hh信号通路的能力。体外研究表明，其对肿瘤细胞系的微摩尔抑制活性较低，而口服给药则显示出优异的体内ADME特性。在体外和异种移植小鼠模型中，化合物5均成为结肠癌细胞最有效和最安全的抑制剂。基于这些数据，可以从临床研究的角度优先考虑5进一步开发。

  5‘-Tethered Stilbene Derivatives as Fidelity- and Affinity-Enhancing Modulators of DNA Duplex Stability

  摘要：

  A series of 5'-linked stilbene-DNA conjugates with different substituents in the distal aromatic ring of the stilbene was prepared, and the effect of the modifications on duplex stability was determined via UV-melting curves. A trimethoxystilbene derivative as a 5'-substituent increases duplex melting points by up to 12.2 degrees C per modification. With this alkoxystilbene substituent, terminal mismatches in DNA duplexes lower the melting point by up to 23.4 degrees C over the perfectly matched control, whereas terminal mismatches in unmodified DNA cause melting point depressions of no more than 6.1 degrees C. An aminomethylstilbene substituent linked to an oligopyrrolamide minor groove binder increases the melting point of an all-A/T decamer by up to 32.7 degrees C, thus shifting the melting point into a range typical for duplexes with statistical G/C-content. An affinity- and selectivity-enhancing effect was also observed when the trimethoxystilbene cap was employed on a small DNA microarray. The phosphoramidite of the trimethoxystilbene can be readily employed in automatic DNA synthesis, facilitating the generation of DNA chips with improved fidelity.

  A variety of stable, safe, and soluble arenediazonium triflates ArN2+ TfO– were obtained easily by diazotization of anilines with tert‐butyl nitrite in the presence of triflic acid. They are highly reactive, forming aromatic iodides, azides, and boronic acids, and also undergo an unusual metal‐free chloro‐dediazonization with chloroform and CCl4.
