  DNA-Dependent Protein Kinase (DNA-PK) Inhibitors. Synthesis and Biological Activity of Quinolin-4-one and Pyridopyrimidin-4-one Surrogates for the Chromen-4-one Chemotype

  摘要：

  Following the discovery of dibenzo[b,d]thiophen-4-yl)-2-morpholino-4H-chromen-4-one (NU7441) (Leahy, J. J. J.; Golding, B. T.; Griffin, R. J.; Hardcastle, I. R.; Richardson, C.; Rigoreau, L.; Smith, G. C. M. Bioorg. Med. Chem. Lett. 2004, 14, 6083-6087) as a potent inhibitor (IC50 = 30 nM) of DNA-dependent protein kinase (DNA-PK), we have investigated analogues in which the chromen-4-one core template has been replaced by aza-heterocyclic systems: 9-substituted 2-morpholin-4-ylpyrido[1,2-a]-pyrimidin-4-ones and 8-substituted 2-morpholin-4-yl-1 H-quinolin-4-ones. The 8- and 9-substituents were either dibenzothiophen-4-yl or dibenzofuran-4-yl, which were each further substituted at the 1-position with water-solubilizing groups [NHCO(CH2)(n) NR1 R-2, where n = 1 or 2 and the moiety (RRN)-R-1-N-2 was derived from a library of primary and secondary amines (e.g., morpholine)]. The inhibitors were synthesized by employing a multiple-parallel approach in which the two heterocyclic components were assembled by Suzuki-Miyaura cross-coupling. Potent DNA-PK inhibitory activity was generally observed across the compound series, with structure activity studies indicating that optimal potency resided in pyridopyrimidin-4-ones bearing a substituted dibenzothiophen-4-yl group. Several of the newly synthesized compounds (e.g., 2-morpholin-4-yl-N-[4-(2-morpholin-4-yl-4-oxo-4H-pyrido[1,2-a]-pyrimidin-9-yl)dibenzothiophen-1-yl]acetamide) combined high potency against the target enzyme (DNA-PK IC50 = 8 nM) with promising activity as potentiators of ionizing radiation-induced cytotoxicity in vitro.

  摘要：

  以选定的芳基和杂芳基为取代基合成了 8-取代的 2-吗啉-4-基-喹啉-4-酮和 9-取代的 2-吗啉-4-基-吡啶并[1,2-a]嘧啶-4-酮，作为 DNA 依赖性蛋白激酶的潜在抑制剂。在制备 8-取代的 2-吗啉-4-基-喹啉-4-酮的过程中，采用了铃木交叉偶联法的多重平行方法。为此，需要 8-溴-2-吗啉-4-基-喹啉-4-酮作为中间体。这种化合物是通过调整文献路线获得的，在该路线中，(2-溴苯胺基)-吗啉-4-基-5-亚甲基-2,2-二甲基[1,3]二噁烷-4,6-二酮的热环缩合得到 8-溴-2-吗啉-4-基-喹啉-4-酮。以 9-羟基-2-吗啉-4-基-吡啶并[1,2-a]嘧啶-4-酮 O-三氟甲磺酸酯为中间体，利用铃木交叉偶联法制备了 9-取代的 2-吗啉-4-基-吡啶并[1,2-a]嘧啶-4-酮。8-取代的 2-吗啉-4-基-喹啉-4-酮和 9-取代的 2-吗啉-4-基-吡啶并[1,2-a]嘧啶-4-酮都是 DNA 依赖性蛋白激酶的抑制剂。当取代基为二苯并噻吩-4-基、二苯并呋喃-4-基或二苯并噻吩-3-基时，观察到的 IC50 值在纳摩尔范围内。有趣的是，吡啶嘧啶酮和喹啉酮与之前报道的相应的 8-取代 2-吗啉-4-基-苯并吡喃-4-酮基本等效（I. R. Hardcastle、X. Cockcroft、N. J. Curtin、M. Desage El-Murr、J. J. J. Leahy、M. Stockley、B. T. Golding、L. Rigoreau、C. Richardson、G. C. M. Smith 和 R. J. Griffin，J. Med.Chem.，2005，48，7829-7846）。
