ANTI-INFLUENZA VIRUS COMPOUND, PREPARATION METHOD AND USE THEREOF
摘要:
Provided are a compound of formula (I-a), an isomer thereof or a pharmaceutically acceptable salt thereof as a Hemagglutinin inhibitor, and a preparation method thereof. The compound is useful for preparing a medicament for treating a disease related to Hemagglutinin.
PBr3-mediated reductivedeoxygenation of α-aryl-pyridinemethanols to provide arylmethylpyridines is described, the alcohol substrate scope is explored, free radical trap TEMPO (2,2,6,6-tetramethyl-1-piperidinyloxy) is introduced, and the hydrogen source of the methylene product is defined. The unexpected reaction enabled us to prepare previously inaccessible, novel EP1 antagonists.

chloroform indicate that such a structural matching remarkably facilitates the intramolecular energy and electron transfer and charge separation between the two chromophores and also retards the recombination of the charge-separated state. Removing one hydrogen bond considerably reduces the energy and electron transfer. Further removing another one leads to no important interaction between the chromophores
通过共价连接发色团在氢键芳基酰胺衍生的折叠架桥的相对端,已经合成了四个卟啉桥-C 60二联体。为了比较,还制备了相同构架的四种不含C 60的卟啉衍生物。完全氢键连接的桥使连接的卟啉和C 60部分以面对面的方式接触。1个在氯仿中的1 H NMR,UV-vis和荧光研究表明,这种结构匹配显着促进了两个发色团之间的分子内能量和电子转移以及电荷分离,并且还阻碍了电荷分离状态的重组。除去一个氢键会大大减少能量和电子转移。进一步除去另一种不会导致生色团之间发生重要的相互作用。
