3-b]quinolines. Separate cyclization was also performed under acidic conditions on 2-(arylamino)phenones in order to obtain acridines and related compounds. Most of the synthesized compounds were screened for their antiproliferative activity in A2058 melanoma cells, and against a panel of disease-relevant kinases such as mammalian CDK5/p25, PIM1, CLK1, DYRK1A, GSK3α/β, Haspin and leishmanial CK1. The
因为Isatin的N-芳基化仅可与碘二茂铁一起使用(且收率低),所以我们使用2-氨基苯酮的N-芳基化和随后的氧化环化反应来获得各种N-芳基化的Iatins。在这项工作的过程中,我们观察到使用2-碘呋喃,2-碘苯并呋喃和2-碘苯并噻吩的N-芳基化反应不会产生预期的衍生物,但会生成(苯并)呋喃-和(苯并)噻吩[2,3- b]喹啉。为了获得a啶和相关化合物,还在酸性条件下对2-(芳基氨基)苯酮进行了单独的环化。筛选了大多数合成的化合物在A2058黑色素瘤细胞中的抗增殖活性,以及针对一系列疾病相关激酶(如哺乳动物CDK5 / p25,PIM1,CLK1,DYRK1A,GSK3α/β,Haspin和利什曼体CK1)的抗增殖活性。报告了生物学结果。
