  摘要：

  A series of 3-methyl-10-(substituted-phenyl)flavins was prepared and tested for antimalarial activity against the lethal parasite Plasmodium vinckei in mice. Several of these analogues were found to be effective antimalarial agents. A quantitative structure-activity relationship study was undertaken with 44 analogues and no satisfactory relationship could be established.

  摘要：

  为了评估分子内酸催化对特定黄素反应性的影响，合成了3-甲基-10-(2-羟基苯基)异黄素（1(2OH)）和3-甲基-10-(2-羟基-1-萘基)异黄素（2(2OH)），并将其氧化还原性质与参考黄素如3-甲基-10-(2-甲氧基苯基)异黄素（1(2OMe)）和3-甲基-10-(2-甲氧基-1-萘基)异黄素（2(2OMe)）进行了比较。1(2OH)和2(2OH)的pKa值分别为7.7和7.0，均低于3-甲基-10-(4-羟基苯基)异黄素（1(4OH)：pKa 8.6）。因此，在反应的初始状态（即氧化状态）下，2′-OH和N(1)形成氢键的可能性较小。X射线晶体学研究表明，苯环与异黄素环之间的夹角为79.7°，而2′-OH基团与晶体格中包含的甲醇形成氢键。在30 °C的乙腈中，1-苯基-1,4-二氢烟酰胺未被1(2OMe)、1(4OH)和2(2OMe)氧化。另一方面，1(2OH)和2(2OH)（在10-芳基取代基的2′位置具有酸性OH基团）发生了氧化。分子内酸催化的存在表明，2′-OH和N(1)至少可以在反应的过渡态或最终状态（即还原状态）下相互作用。一般来说，氧化的黄素采用“平面”结构，立体张力较大，而还原的黄素则采用“弯曲”结构，立体张力较小。由于过渡态的结构或多或少与还原形式相似，因此在从紧张的初始状态转变为放松的过渡状态时，氢键相互作用可能会增强。这是黄素介导反应中酸催化的新颖例子。

  A number of 6,9-disubstituted cyclohepta[b]pyrimido[5,4-d]pyrrole-8(6H),10(9H)-dione derivatives have been synthesized in good to moderate yields by the reaction of 6-amino-3-methyluracil derivatives with 2-chlorotropone in an enamine-alkylation process, subsequent condensation of the amino group with the carbonyl function, dehydrochlorination, and dehydration.

  Synthesis of 6,9-disubstituted cyclohepta[b]pyrimido[5,4-d]pyrrole-8(6H),10(9H)-diones 7a–g was accomplished by ring opening and ring closure sequences of 9-substituted cyclohepta[b]pyrimido[5,4-d]furan-8,10(9H)-dione derivatives induced by several amines. Furthermore, alternative synthetic methodology for compounds 7a–e was also accomplished by single-step reaction of 2-chlorotropone with 6-aminouracil

  6,9-二取代的环庚[ b ]嘧啶基[5,4 - d ]吡咯-8（6 H），10（9 H）-二酮7a – g的合成是通过9-取代的开环和闭环顺序完成的几种胺诱导的环庚[ b ]嘧啶基[5,4 - d ]呋喃-8,10（9 H）-二酮衍生物。此外，化合物7a - e的替代合成方法也可以通过在适度的条件下使2-氯托酮与6-氨基尿嘧啶衍生物进行一步反应来完成。7a的X射线晶体分析进行了澄清结构特征。通过紫外可见光谱和还原电势（相对于Ag / AgNO 3为−1.24至−1.39 V ）研究了7a – e的性质。在好氧条件下，进行了7a - d对某些胺的新型光诱导氧化反应，得到的亚胺的收率超过100％[基于化合物7a - d ]，表明该氧化反应发生在自动回收过程中。

  Novel deazaflavin-cholestane hybrid compounds, 3',8'-disubstituted-5'-deazacholest-2,4-dieno[2,3g] pteridine-2',4'(3'H, 8'H)-diones, have been synthesized by condensation reaction between 6-(monosubstituted amino)-pyrimidin-2,4(1H,3H)-diones and 2-hydroxymethylenecholest-4-en-3-one in presence of p-toluenesulfonic acid monohydrate and diphenyl ether. The antitumor activities against human tumor cell lines (CCRF-HSB-2 and KB cells) have been investigated in vitro, and many of these compounds showed promising antitumor activities. Furthermore, molecular docking study using LigandFit within the software package Discovery Studio 1.7 was done for lead optimization of these compounds as potential PTK inhibitors. In general, all of the synthesized steroid-hybrid compounds showed good binding affinities into PTK (PDB code: 1t46). (C) 2008 Elsevier Ltd. All rights reserved.
