  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of DNA-dependent protein kinase (DNA-PK), we have investigated analogues in which the chromen-4-one core template has been replaced by aza-heterocyclic systems: 9-substituted 2-morpholin-4-ylpyrido[1,2-a]-pyrimidin-4-ones and 8-substituted 2-morpholin-4-yl-1 H-quinolin-4-ones.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.

  损害合并：在临床前肿瘤模型中的单一疗法和联合治疗中发现了具有良好药代动力学特性和有希望的功效的有效，高选择性，口服ATR抑制剂BAY 1895344。

  摘要：

  ATR激酶通过激活DNA损伤修复的基本信号通路，特别是对复制压力的响应，在DNA损伤应答中起关键作用。由于DNA损伤和复制压力是基因组不稳定的主要来源，因此选择性ATR抑制已被认为是癌症治疗中一种有希望的新方法。现在，我们报告新颖的临床ATR抑制剂BAY 1895344的鉴定和临床前评估。从喹啉2开始由于ATR抑制活性较弱，针对效价，选择性和口服生物利用度的前导优化工作导致发现了有效的，高选择性的，口服的ATR抑制剂BAY 1895344，在携带某些DNA损伤的癌症异种移植模型中显示出强大的单一疗法功效维修缺陷。此外，BAY 1895344与某些诱导DNA损伤的化学疗法联合治疗可产生协同的抗肿瘤活性。BAY 1895344目前正在对晚期实体瘤和淋巴瘤（NCT03188965）的患者进行临床研究。

  8-Substituted 2-morpholin-4-yl-quinolin-4-ones and 9-substituted 2-morpholin-4-yl-pyrido[1,2-a]pyrimidin-4-ones with selected aryl and heteroaryl groups as the substituent have been synthesised as potential inhibitors of DNA-dependent protein kinase. A multiple-parallel approach, employing Suzuki cross-coupling methodology, was utilised in the preparation of 8-substituted 2-morpholin-4-yl-quinolin-4-ones. For this purpose 8-bromo-2-morpholin-4-yl-quinolin-4-one was required as an intermediate. This compound was obtained by adapting a literature route in which thermal cyclocondensation of (2-bromoanilino)-morpholin-4-yl-5-methylene-2,2-dimethyl[1,3]dioxane-4,6-dione afforded 8-bromo-2-morpholin-4-yl-quinolin-4-one. A multiple-parallel approach, employing Suzuki cross-coupling methodology, was also utilised to prepare 9-substituted 2-morpholin-4-yl-pyrido[1,2-a]pyrimidin-4-ones using 9-hydroxy-2-morpholin-4-yl-pyrido[1,2-a]pyrimidin-4-one O-trifluoromethanesulfonate as an intermediate. 8-Substituted 2-morpholin-4-yl-quinolin-4-ones and 9-substituted 2-morpholin-4-yl-pyrido[1,2-a]pyrimidin-4-ones were both inhibitors of DNA-dependent protein kinase. When the substituent was dibenzothiophen-4-yl, dibenzofuran-4-yl or biphen-3-yl, IC50 values in the low nanomolar range were observed. Interestingly, the pyridopyrimidinones and quinolinones were essentially equipotent with the corresponding 8-substituted 2-morpholin-4-yl-chromen-4-ones previously reported (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 and R. J. Griffin, J. Med. Chem., 2005, 48, 7829–7846).

  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）。
