  • MONOMERS CAPABLE OF DIMERIZING IN AN AQUEOUS SOLUTION, AND METHODS OF USING SAME
    申请人:Barany Francis

    Described herein are monomers capable of forming a biologically useful multimer when in contact with one, two, three or more other monomers in an aqueous media. In one aspect, such monomers may be capable of binding to another monomer in an aqueous media (e.g. in vivo) to form a multimer, (e.g. a dimer). Contemplated monomers may include a ligand moiety, a linker element, and a connector element that joins the ligand moiety and the linker element. In an aqueous media, such contemplated monomers may join together via each linker element and may thus be capable of modulating one or more biomolecules substantially simultaneously, e.g., modulate two or more binding domains on a protein or on different proteins.
    本发明描述了在水中介质中与一个、两个、三个或更多其他单体接触时能够形成具有生物学用途的多聚体的单体。在一方面,这样的单体可能能够在水介质中(例如,体内)与另一个单体结合形成多聚体(例如,二聚体)。考虑的单体可能包括一个配体部分、一个连接元素和一个连接器元素,连接器元素连接配体部分和连接元素。在水介质中,这样的考虑单体可能通过每个连接元素相互连接,因此可能能够实质上同时调节一个或多个生物分子,例如,调节蛋白质上的两个或多个结合域,或者调节不同蛋白质上的结合域。

    The present invention is directed to method of using a collection of monomers capable of forming multimers as a fluorescence reporter in different applications such as ligand detection/screening, disease diagnosis, drug discovery or screening, fluorescent labeling and imaging, or other fluorescent methodologies. Each monomer in the collection includes one or more ligand elements useful for binding to a target molecule with a dissociation constant of less than 300 μM and a linker element connected to the ligand elements directly or indirectly through a connector. Association of linker elements of different combinations of monomers, with their ligand elements bound to the target molecule to form a multimer, will generate a unique fluorescent signature different from that produced by those monomers either alone or in association with each other in the absence of the target molecule, when subjected to electromagnetic excitement.
    本发明涉及使用一组能够形成多聚体的单体作为荧光报告物在不同应用中的方法,例如配体检测/筛选、疾病诊断、药物发现或筛选、荧光标记和成像,或其他荧光方法学。该组合中的每个单体均包括一个或多个配体元素,用于与解离常数小于300μM的靶分子结合,并且连接到配体元素的连接器通过直接或间接连接到配体元素。不同单体组合的连接器元素与其配体元素结合到靶分子形成多聚体,将产生一种独特的荧光特征,与那些单体单独或在没有靶分子的情况下相互结合时产生的荧光特征不同,当受到电磁激发时。

    Coumarin possesses the aromatic group and showed plentiful activities, such as antioxidant, preventing asthma and antisepsis. In addition, coumarin derivatives usually possess good solubility, low cytotoxicity and excellent cell permeability. In our study, we synthesized the compound bridge methylene tacrine (BMT), which has the classical pharmacophore structure of Tacrine (THA). Based on the principle of active substructure splicing, BMT was used as a lead compound and synthesized coumarin–BMT hybrids by introducing coumarin to BMT. In this work, 21 novel hybrids of BMT and coumarin were synthesized and evaluated for their inhibitory activity on AChE. All obtained compounds present preferable inhibition. Compound 8b was the most active compound, with the value of Ki as 49.2 nM, which was higher than Galantamine (GAL) and lower than THA. The result of molecular docking showed that the highest binding free energy was −40.43 kcal/mol for compound 8b, which was an identical trend with the calculated Ki.

    香豆素具有芳香基团并表现出丰富的活性,例如抗氧化、预防哮喘和防腐作用。此外,香豆素衍生物通常具有良好的溶解性、低细胞毒性和优异的细胞渗透性。在我们的研究中,我们合成了桥连甲基他克林(BMT)化合物,其具有经典的他克林(THA)药效团结构。基于活性亚结构拼接原理,我们将BMT作为引物化合物,并通过将香豆素引入BMT中合成了香豆素-BMT杂交物。在这项工作中,我们合成了21种新的BMT和香豆素的杂交物,并评估了它们对AChE的抑制活性。所有获得的化合物均表现出优越的抑制活性。化合物8b是最活跃的化合物,其Ki值为49.2 nM,高于加兰他敏(GAL)但低于THA。分子对接的结果表明,化合物8b的最高结合自由能为-40.43 kcal/mol,这与计算的Ki值呈现相同的趋势。
