  摘要：

  黏着斑激酶（FAK）是负责各种肿瘤类型发展的细胞内非受体酪氨酸激酶。为了探索新的有效抑制剂，在基于结构的设计策略的基础上，设计并合成了两个系列的2,4-二取代-7 H-吡咯并[2,3- d ]嘧啶衍生物。生物学评估表明，这些新化合物中的大多数可以有效抑制FAK激酶，从而导致有希望的抑制剂对抗U-87MG，A-549和MDA-MB-231癌细胞的增殖。其中，优化的化合物18h 在U-87MG，A-549和MDA-MB-231细胞中均有效抑制酶（IC 50 = 19.1 nM），并显示出比TAE-226更强的效力，IC 50分别为0.35、0.24和0.34μM。化合物18h是多靶激酶抑制剂。此外，化合物18h 对正常人细胞株HK2的细胞毒性也较小（IC 50 = 3.72μM）。根据流式细胞术和伤口愈合试验结果，化合物18h有效诱导MDA-MB-231细胞凋亡和G0 / G1期阻滞，并抑制U

  日期：2001.9.1

  A new strategy for the solid-phase synthesis of sulfonamides is described. The Kenner safety-catch strategy has been modified such that the carboxylic acid component remains attached to the solid support while the sulfonamide portion is released into solution. An initial demonstration of the scope of this strategy is presented, along with an analysis of the cleavage characteristics and extension to

  日期：2018.8.17

  A copper‐catalyzed one‐pot approach to α‐aryl amidines from terminal alkynes, sulfonyl azides, and aryl sulfonamides via a Truce‐Smiles rearrangement under mild condition in good to excellent yields was reported for the first time. The formation of such aryl‐sp3 C−C bond previously could not be directly achieved by the common method. The stoichiometry of substrates played an important role in improving

  The direct sulfonylation of 4,5-dichloropyridazin-3-ones with some benzenesulfonyl chlorides in the presence of base in tetrahydrofuran gave only the corresponding N-sulfonylated product. The reaction of 2-benzenesulfonyl-4,5-dichloropyridazin-3-ones with some aliphatic amines under neutral conditions afforded 5-alkylamino-2-benzenesulfonyl-4-chloropyridazin-3-ones and/or the corresponding N-alkyl
