  An Optimized RAD51 Inhibitor That Disrupts Homologous Recombination without Requiring Michael Acceptor Reactivity

  摘要：

  Homologous recombination (HR) is an essential process in cells that provides repair of DNA double-strand breaks and lesions that block DNA replication. RAD51 is an evolutionarily conserved protein that is central to HR. Overexpression of RAD51 protein is common in cancer cells and represents a potential therapeutic target in oncology. We previously described a chemical inhibitor of RAD51, called RI-1 (referred to as compound 1 in this report). The chloromaleimide group of this compound is thought to act as a Michael acceptor and react with the thiol group on C319 of RAD51, using a conjugate addition-elimination mechanism. In order to reduce the likelihood of off-target effects and to improve compound stability in biological systems, we developed an analogue of compound 1 that lacks maleimide-based reactivity but retains RAD51 inhibitory activity. This compound, 1-(3,4-dichlorophenyl)-3-(4-methoxyphenyl)-4-morpholino-1H-pyrrole-2,5-dione, named RI-2 (referred to as compound 7a in this report), appears to bind reversibly to the same site on the RAD51 protein as does compound 1. Like compound 1, compound 7a specifically inhibits HR repair in human cells.

  Heterocyclization reactions between N-arylmaleimides and 6-aminouracils were studied in detail. It was established that several directions are possible depending on the nature of reaction medium and the substituent character in the uracil component. The synthetic procedure leading to N-phenyl-2,4,7-trioxopyrido[2,3-d]pyrimidine-5-carboxamides in good-to-high yields was developed and key stages of the corresponding reaction were established.

  Heterocyclization reactions between derivatives of 5-aminopyrazoles and N-arylmaleimides were studied and it was established that several directions are possible. Cyclizations involving 1,3-unsubstituted 5-aminopyrazoles yielded mixtures of two regioisomeric compounds, pyrazolo[1,5-a]pyrimidine-7-carboxamides and pyrazolo[3,4-b]pyridine-4-carboxamides. Reactions of 4-substituted 5-aminopyrazoles in boiling acetic acid or N,N-dimethylformamide in most cases gave pyrazolo[1,5-a]pyrimidine-7-carboxamides as the sole product. The treatment of 1-substituted 5-aminopyrazoles with maleimides possesses high selectivity only in N,N-dimethylformamide yielding pyrazolopyridines while in acetic acid the formation mixtures with pyrrolopyrazolones is observed. The key intermediates of the reaction studied were isolated and discussed.

  研究人员对 5-氨基吡唑衍生物和 N-芳基马来酰亚胺之间的异环化反应进行了研究，并确定了几个可能的方向。涉及 1,3- 未取代的 5-氨基吡唑的环化反应产生了两种异构体的混合物，即吡唑并[1,5-a]嘧啶-7-羧酰胺和吡唑并[3,4-b]吡啶-4-羧酰胺。在大多数情况下，4-取代的 5-氨基吡唑在沸腾的乙酸或 N,N-二甲基甲酰胺中反应生成的唯一产物是吡唑并[1,5-a]嘧啶-7-羧酰胺。用马来酰亚胺处理 1-取代的 5-氨基吡唑，只有在 N,N-二甲基甲酰胺中才具有高选择性，生成吡唑并吡啶，而在乙酸中则会与吡咯并吡唑酮形成混合物。对所研究反应的关键中间产物进行了分离和讨论。
