制备方法与用途

盐酸甲氧苄啶是一种抑菌抗生素,同时也是一种口服活性的二氢叶酸还原酶抑制剂。它对多种革兰氏阳性及阴性需氧菌具有抗菌作用,在研究尿路感染、志贺氏菌病和肺孢子虫肺炎等方面显示出潜力。此外,当与锌结合使用时,盐酸甲氧苄啶还能有效抑制禽流感病毒在鸡胚中的繁殖。

  • Shifted Selectivity in Protonation Enables the Mild Deuteration of Arenes Through Catalytic Amounts of Bronsted Acids in Deuterated Methanol
    作者:Oliver Fischer、Anja Hubert、Markus R. Heinrich

    日期:2020.9.18
    effect” of the solvent methanol, deuterations of electron-rich aromatic systems can be carried out under mild acid catalysis and thus under far milder conditions than known so far. The exceptional functional group tolerance observed under the optimized conditions, which even includes highly acid-labile groups, results from a hitherto unexploited shifted selectivity in protonation, and enabled simple
    利用溶剂甲醇的“差异化作用”,可以在温和的酸催化下并且因此在比迄今已知的条件温和得多的条件下,对富电子芳族体系进行氘化。在优化条件下观察到的出色的官能团耐受性(甚至包括高度酸不稳定的基团)是由于迄今为止未利用的质子化选择性转移而导致的,并使得能够简单,直接地获得复杂的氘标记化合物。

    公开(公告)日:2021-10-13
    Provided is a method for the preparation of a deuterated or tritiated aromatic compound via deuteration or tritiation of an aromatic starting compound which comprises an aromatic ring or a fused aromatic ring system which may be carbocyclic or hetercyclic and which carries at least one hydrogen atom directly bonded to a carbon ring atom of an aromatic ring, said method comprising: a) providing a liquid composition wherein the aromatic starting compound is dissolved or dispersed in a deuterated or tritiated solvent which is not water, or in a solvent system comprising at least one deuterated or tritiated solvent which is not water; and b) replacing at least one hydrogen atom directly bonded to a carbon ring atom of an aromatic ring comprised by the aromatic starting compound with deuterium or tritium via the transfer of at least one deuterium of tritium atom from the deuterated or tritiated solvent to the aromatic starting compound dissolved or dispersed in the liquid composition in the presence of an acid, to convert the aromatic starting compound to a deuterated or tritiated aromatic compound which comprises an aromatic ring or a fused aromatic ring system which may be carbocyclic or hetercyclic and which carries at least one deuterium or tritium atom directly bonded to a carbon ring atom of an aromatic ring.

  • Engineered receptor/ligand system for delivery of therapeutic agents
    申请人:University of Florida Research Foundation, Incorporated
    公开号:US11000597B2
    公开(公告)日:2021-05-11
    Provided herein are compositions and methods related to targeted delivery of a therapeutic or diagnostic agent to a subject utilizing an engineered receptor-ligand system, such as an engineered dockerin-cohesin system. As described herein, previously-developed targeted delivery systems for delivering therapeutic and diagnostic agents to a tissue of interest have drawbacks that have not been addressed to date. For example, with respect to the blood-brain barrier (BBB) and the blood-cerebrospinal fluid barrier (BCSFB), both of which hamper delivery of agents to the brain, others have relied on the use of endogenously expressed receptors, like the transferrin receptor, to assist the agent across the barriers.
    本文提供了与利用工程受体-配体系统(如工程 dockerin-cohesin系统)向受试者靶向递送治疗剂或诊断剂有关的组合物和方法。如本文所述,以前开发的将治疗剂和诊断剂靶向输送到相关组织的靶向输送系统存在迄今尚未解决的缺点。例如,血脑屏障(BBB)和血-脑脊液屏障(BCSFB)都会阻碍将药剂输送到大脑,因此其他药物依赖于使用内源性表达的受体(如转铁蛋白受体)来帮助药剂穿过屏障。
