  DMSO, DMAc, and NMP in nucleophilic aromatic substitution reactions (SNAr), a simple and environmentally friendly alternative is reported. Use of a “benign-by-design” nonionic surfactant, TPGS-750-M, in water enables nitrogen, oxygen, and sulfur nucleophiles to participate in SNAr reactions. Aromatic and heteroaromatic substrates readily participate in this micellar catalysis, which takes place at or

  highly potent BET bromodomain inhibitors. Further druggability optimization led to the discovery of compound 38 as a potential preclinical candidate. Significantly, compared with ABBV-075, which exhibits a 63-fold selectivity for BRD4(1) over EP300, compound 38 demonstrates an excellent selectivity for the BET bromodomain family over other bromodomains, with an ∼1500-fold selectivity for BRD4(1) over

  溴结构域和末端外（BET）家族蛋白最近已成为有希望的癌症治疗药物靶标。在这项研究中，鉴定了一个8-甲基-吡咯并[1,2-a]吡嗪-1（2H）-一个片段（47）作为BET溴结构域的新结合物，随后将片段47掺入了该载体的支架中。最近进入I期临床试验的ABBV-075使能够产生一系列高效的BET溴结构域抑制剂。进一步的可药物性优化导致发现化合物38作为潜在的临床前候选药物。值得注意的是，与ABBV-075相比，BBB4（1）对BRD4（1）的选择性是EP300的63倍，化合物38对BET溴结构域家族的选择性比其他溴结构域好，而BRD4（1）的选择性约为1500倍。超过EP300。

  organic synthesis in recyclable water. This includes homogeneous catalysis (including examples employing only ppm levels of catalyst), heterogeneous catalysis, and biocatalytic transformations, including a multistep chemoenzymatic sequence. Use of Savie frequently leads to significantly higher yields than do conventional surfactants, while obviating the need for waste-generating organic solvents.

  Savie 是一种可生物降解的表面活性剂，源自维生素 E 和聚肌氨酸 (PSar)，开发用于可循环水中的有机合成。这包括均相催化（包括仅使用 ppm 级催化剂的例子）、多相催化和生物催化转化，包括多步化学酶序列。使用 Savie 通常会比传统表面活性剂产生显着更高的产率，同时无需使用产生废物的有机溶剂。
