  Design of novel N-(2,4-dioxo-1,2,3,4-tetrahydro-thieno[3,2-d]pyrimidin-7-yl)-guanidines as thymidine phosphorylase inhibitors, and flexible docking to a homology model

  摘要：

  A novel class of thymidine phosphorylase (TP) inhibitors has been designed based on analogy to the enzyme substrate as well as known inhibitors. Flexible docking studies, using a homology model of human TP, of the designed N-(2,4-dioxo-1,2,3,4-tetrahydro-thieno[3,2-d]pyrimidin-7-yl)-guanidines as well as their synthetic precursors provide insight into the observed experimental trends in binding affinity.

  Potent selective thienoxazinone inhibitors of herpes proteases

  摘要：

  Thieno[3,2-d]oxazinones are potent selective, mechanism-based inhibitors of the herpes proteases with good aqueous stability. Specificity between the HSV and CMV proteases varies across the series: compounds 14b and 14c are submicromolar HSV protease inhibitors with modest CMV protease inhibition, 14g is a selective CMV protease inhibitor, and 32 inhibits both enzymes with an IC50 of about 1 mu M.

  Novel thienopyridones with antihypertensive activity have the formula I, ##STR1## wherein the ring A represents an optionally substituted thiophene ring; m is 0 or 1; n is 0, 1 or 2; R is lower alkyl and R.sub.1 is lower alkyl. The fused thieno-ring may carry one or two substituents. Formula I encompasses thieno[3,2-b]pyridones, thieno[3,4-b]pyridones and thieno[2,3-b]pyridones. Processes for preparing the novel thienopyridones and pharmaceutical compositions containing them are described. Pharmaceutically acceptable acid addition salts of the compounds of formula I are also described. The thienopyridones of formula I are antihypertensive agents and are also indicated for use in treating heart failure and ischaemic heart disease.

  日期：1998.1.12

  The synthesis of the monomeric building block 13 and its constitutional isomer 12 of a new type of DNA analog, distamycin-NA, is presented (Schemes 1 and 2). This building block consists of a uracil base attached to a thiophene core unit via a biaryl-like axis. Next to the biaryl-like axis on the thiophene chromophore, a carboxy and an amino substituent are located allowing for oligomerization via

  提出了新型的DNA类似物，双霉素-NA的单体结构单元13及其组成异构体12的合成（方案1和2）。该结构单元由尿嘧啶碱基组成，该碱基通过联芳基样轴与噻吩核心单元相连。在噻吩发色团上的联芳基样轴的旁边，有一个羧基和一个氨基取代基，可通过肽偶联进行低聚。通过对相应的硝基衍生物10和11进行X射线分析，建立了围绕联芳基样轴的结构证据和构象偏好。。因此，尿嘧啶碱基相对于噻吩核是螺旋式扭曲的，并且在晶体中的两个尿嘧啶碱基之间发生了二齿H键。使用分别在THF / LiCl和DMF中的二环己基碳二亚胺（DCC），将两个氨基酸结构单元12和13偶联以得到二聚体15和16。尽管二聚体15在室温下在NMR时间尺度上没有显示出对映异构性，但是由于绕其联芳基样轴的旋转受阻，其异构体16以不同的非对映异构体的形式出现。可变温度1 H-NMR实验可确定16 16 ±1 kcal / mol的旋转势垒。实验数据通过AM1计算得到补充。
