    • The present invention relates to a novel mammalian anti-opioid receptor protein (OFQR), peptide ligands (such as OFQ) that bind to OFQR, and methods of using the OFQ peptide and analogues to reverse the physiologic effects of opiates such as morphine. The isolation, characterization and pharmacological use of the endogenous peptide ligand is described. A particular embodiment of the OFQ peptide is a heptadecapeptide having an FGGF aminoterminal motif. The peptide specifically binds to an OFQ receptor protein heterologously expressed in mammalian cells. The peptide does not bind with high affinity to mu , delta or kappa receptors, but it antagonizes opioid mediated effects (such as analgesia and hypothermia) without increasing nociceptive sensitivity. Tyrosine substitution variants of the peptide ligand specifically bind to the opioid receptor and can be radioiodinated. Also provided are methods of making such peptide ligands and OFQR antagonists, and methods of using the ligands for diagnostic and therapeutic uses and for the identification of other naturally-occurring or synthetic opioid receptor ligands.
    • 本发明涉及新型哺乳动物抗阿片类受体蛋白(OFQR),与OFQR结合的肽配体(如OFQ),以及使用OFQ肽和类似物逆转阿片剂如吗啡的生理作用的方法。 描述了内源肽配体的分离,表征和药理学应用。 OFQ肽的具体实施方案是具有FGGF氨基末端基序的十七肽。 该肽特异性结合在哺乳动物细胞中异源表达的OFQ受体蛋白。 肽不能以高亲和力结合mu,δ或κ受体,但是它不会增加伤害敏感性,而是拮抗阿片样物质介导的作用(如镇痛和低体温)。 肽配体的酪氨酸取代变体与阿片受体特异性结合,可以放射性碘化。 还提供了制备这种肽配体和OFQR拮抗剂的方法,以及使用该配体进行诊断和治疗用途以及鉴定其它天然存在或合成的阿片受体配体的方法。

    • This invention provides novel methods and reagents for specifically delivering biologically active compounds to phagocytic mammalian cells. The invention also relates to specific uptake of such biologically active compounds by phagocytic cells and delivery of such compounds to specific sites intracellularly. The invention specifically relates to methods of facilitating the entry of antimicrobial drugs and other agents into phagocytic cells and for targeting such compounds to specific organelles within the cell. The invention specifically provides compositions of matter and pharmaceutical embodiments of such compositions comprising conjugates of such antimicrobial drugs and agents covalently linked to particulate carriers generally termed microparticles. In particular embodiments, the antimicrobial drug is covalently linked to a microparticle via an organic linker molecule which is the targeted of a microorganism-specific protein having enzymatic activity. Thus, the invention provides cell targeting of drugs wherein the target drug is only released in cells infected with a particular microorganism. Alternative embodiments of such specific drug delivery compositions also contain polar lipid carrier molecules effective in achieving intracellular organelle targeting in infected phagocytic mammalian cells. Particular embodiments of such conjugates comprise antimicrobial drugs covalently linked both to a microparticle via an organic linker molecule and to a polar lipid compound, to facilitate targeting of such drugs to particular subcellular organelles within the cell. Also provided are porous microparticles impregnated with antimicrobial drugs and agents wherein the surface or outside extent of the microparticle is covered with a degradable coating that is specifically degraded within an infected phagocytic mammalian cell. Methods of inhibiting, attenuating, arresting, combatting and overcoming microbial infection of phagocytic mammalian cells in vivo and in vitro are also provided.
    • 本发明提供用于特异性递送生物活性化合物给吞噬哺乳动物细胞的新方法和试剂。 本发明还涉及通过吞噬细胞对这些生物活性化合物的特异性吸收并且将这些化合物递送到细胞内的特定位点。 本发明具体涉及促进抗菌药物和其它试剂进入吞噬细胞并将这些化合物靶向细胞内的特定细胞器的方法。 本发明具体提供了这种组合物的组合物和药物实施方案,其包含这种抗微生物药物的共轭物和共价连接到通常称为微粒的颗粒载体的试剂。 在具体实施方案中,抗微生物药物通过有机连接分子与微粒共价连接,有机连接分子是具有酶活性的微生物特异性蛋白质的靶向物。 因此,本发明提供药物的细胞靶向,其中目标药物仅在感染特定微生物的细胞中释放。 这种特定药物递送组合物的替代实施方案还含有有效实现受感染吞噬细胞哺乳动物细胞中细胞内细胞器靶向的极性脂质载体分子。 这种缀合物的具体实施方案包括通过有机连接分子与极性脂质化合物共价连接到微粒上的抗微生物药物,以促进将这些药物靶向细胞内的特定亚细胞器官细胞器。 还提供了浸渍有抗微生物药物和试剂的多孔微粒,其中微粒的表面或外部程度被在受感染的吞噬细胞哺乳动物细胞内特异性降解的可降解涂层覆盖。 还提供了在体内和体外抑制,减弱,阻止,拮抗和克服吞噬哺乳动物细胞的微生物感染的方法。
