  Structure–Activity Relationships of Lysophosphatidylserine Analogs as Agonists of G-Protein-Coupled Receptors GPR34, P2Y10, and GPR174

  摘要：

  Lysophosphatidylserine (LysoPS) is an endogenous lipid mediator generated by hydrolysis of membrane phospholipid phosphatidylserine. Recent ligand screening of orphan G-protein-coupled receptors (GPCRs) identified two LysoPS specific human GPCRs, namely, P2Y10 (LPS2) and GPR174 (LPS3), which, together with previously reported GPR34 (LPS1), comprise a LysoPS receptor family. Herein, we examined the structure-attivity relationships of a series of synthetic LysoPS analogues toward these recently deorphanized LysoPS,receptors, based on the idea that LysoPS can be regarded as consisting of distinct modules (fatty acid, glycerol, and L-Serine) connected by phosphodiester and ester linkages. Starting from the endogenous ligand (1-oleoyl-LysolPS, 1), we optimized the structure of each module and the ester linkage. Accordingly, we identified some structural requirements of each module for potency and for receptor subtype selectivity. Further assembly of individually structure-optimized modules yielded a series of potent and LysoPS receptor subtype-selective agonists, particularly for P2Y10 and GPR174.

  Amphiphilic Phospholipid-Based Riboflavin Derivatives for Tumor Targeting Nanomedicines

  摘要：

  核黄素（RF）是细胞代谢所必需的维生素。最新研究表明，RF通过RF转运蛋白进行内化，而前列腺癌和乳腺癌细胞以及血管生成内皮细胞中转运蛋白的表达量非常高。在此，我们介绍了一种优化的合成方案，利用亚磷酰胺化学方法制备定制的基于磷脂的RF衍生物。制备的RF两亲化合物——RfdiC14——可以插入脂质体配方中，用于靶向药物递送。所得脂质体的流体动力学尺寸为115±5 nm，尺寸分布窄（PDI 0.06），Zeta电位为-52±3 mV。体外摄取研究表明，含RfdiC14的脂质体以一种特定且转运蛋白介导的方式在HUVEC、PC3和A431细胞中强烈内化。为了评估RF在体内的靶向潜力，我们制备了一种在RF和脂质之间含有PEG间隔物的两亲化合物——DSPE-PEG-RF。后者成功掺入长循环近红外标记脂质体（直径141±1 nm，PDI 0.07，Zeta电位为-33±1 mV）。在PC3异种移植小鼠中进行的纵向μCT/FMT生物分布研究表明，与对照组相比，DSPE-PEG-RF功能化脂质体的药代动力学特征相似

  The present invention provides a chemically stable and novel glycero-compound having one or two triple bonds, one molecule of a glycerol and one or two molecules of a fatty alcohol having a triple bond being linked through an ether bond, an organic group being linked to residual hydroxyl groups of the glycerol, which can be used as a membrane material for forming a vesicle membrane due to its high intermolecular cohesive force, and also provides a membrane forming material containing the same. The glycero-compound has a triple bond represented by the following general formula (1): wherein n and m each represents a number of 1 to 17 and the total (n+m) is a number of 4 to 18, n and m may be the same or different, and R represents a hydrogen atom, a metal atom, a phosphoric acid group, or an organic group which may be linked through a phosphoric acid group.

• Synthesis and Evaluation of Lysophosphatidylserine Analogues as Inducers of Mast Cell Degranulation. Potent Activities of Lysophosphatidylthreonine and Its 2-Deoxy Derivative

  In response to various exogenous stimuli, mast cells (MCs) release a wide variety of inflammatory mediators stored in their cytoplasmic granules and this release initiates subsequent allergic reactions. Lysophosphatidylserine (lysoPS) has been known as an exogenous inducer to potentiate histamine release from MCs, though even at submicromolar concentrations. In this study, through SAR studies on lysoPS against MC degranulation, we identified lysoPT, a threonine-containing lysophospholipid and its 2-deoxy derivative as novel strong agonists. LysoPT and its 2-deoxy derivative induced histamine release from MCs both in vitro and in vivo at a concentration less than one-tenth that of lysoPS. Notably, lysoPT did not activate a recently proposed lysoPS receptor on MCs, GPR34, demonstrating the presence of another undefined receptor reactive to both lysoPS and lysoPT that is involved in MC degranulation. Thus, the present strong agonists, lysoPT and its 2-deoxy derivative, will be useful tools to understand the mechanisms of lysoPS-induced activation of degranulation of MCs.
