Eight phenylhydrazone derivatives of pyrimidine-2(1H),4(3H),5,6-tetraone, or 5-oxobarbituric acid (alloxan), are described. Spectroscopic pyrimidine (1Hn.m.r., i.r.) data indicate the presence of extensive hydrogenbonding which, as shown by X-ray crystallographic data for the title hydrazone, includes both intra- and inter-molecular interactions. The title hydrazone, C10H7N5O5, is monoclinic, space
描述了嘧啶-2(1 H),4(3 H),5,6-四酮或5-氧代巴比妥酸(四氧六环)的八种苯hydr衍生物。嘧啶光谱(1 H nmr,ir)数据表明存在广泛的氢键,如标题的X射线晶体学数据所示,该氢键包括分子内和分子间相互作用。标题C 10 H 7 N 5 O 5为单斜晶,空间群P 2 1 / a,a = 9.104(8),b = 17.975(13),c = 10.333(8)Å,β= 113.5( 1)°,Z = 4.2145已在衍射仪上测量了独立反射,并通过直接方法确定了结构,并将其精炼为R 0.074。在不对称单元中有四个独立的氢键:两个分子内键将N(7)–H(7)连接到苯环的o -NO 2基团和巴比妥酸酯环的羰基上,两个分子间键连接通过对称中心将巴比妥酸酯环的NH位点连接至溶剂NN-二甲基甲酰胺氧原子和另一个巴比妥酸酯环的羰基氧原子。
Synthesis, activity evaluation, and docking analysis of barbituric acid aryl hydrazone derivatives as RSK2 inhibitors
The 90 kDa ribosomal S6 kinases (RSKs), especially RSK2, have attracted attention for the development of new anticancer agents. Through structural optimization of the hit compound 1 from our previous study, a series of barbituric acid aryl hydrazone analogues were designed and synthesized as potential RSK2 inhibitors. The most potent one, compound 9, showed a higher activity against RSK2 with an IC50 value of 1.95 mu M. To analyze and elucidate their structure-activity relationship, the homology model of RSK2 N-terminal kinase domain was built and molecular docking simulations were performed, which provide helpful clues to design new inhibitors with desired activities.
