  The G-protein-coupled receptor CXCR4 acts as a coreceptor for human immunodeficiency virus type 1 (HIV-1) infection, as well as being involved in signaling cell migration and proliferation. Compounds that block CXCR4 interactions have potential uses as HIV entry inhibitors to complement drugs such as maraviroc that block the alternate coreceptor CCR5 or in cancer therapy. The peptide T140, which contains five arginine residues, is the most potent antagonist of CXCR4 developed to date. In a search for nonpeptide CXCR4 ligands that could inhibit HIV entry, three series of compounds were synthesized from 12 linear and branched polyamines with 2, 3, 4, 6, or 8 amino groups, which were substituted to produce the corresponding guanidines, biguanides, or phenylguanides. The resulting compounds were tested for their ability to compete with T140 for binding to the human CXCR4 receptor expressed on mammalian cells. The most effective compounds bound CXCR4 with a 50% inhibitory concentration of 200 nM, and all of the compounds had very low cytotoxicity. Two series of compounds were then tested for their ability to inhibit the infection of TZM-bl cells with X4 and R5 strains of HIV-1. Spermine phenylguanide and spermidine phenylguanide inhibited infection by X4 strains, but not by R5 strains, at low micromolar concentrations. These results support further investigation and development of these compounds as HIV entry inhibitors.

  摘要 G 蛋白偶联受体 CXCR4 是人类免疫缺陷病毒 1 型（HIV-1）感染的核心受体，并参与细胞迁移和增殖的信号传递。阻断 CXCR4 相互作用的化合物有可能用作 HIV 进入抑制剂，以补充马拉维若等阻断替代核心受体 CCR5 的药物，或用于癌症治疗。多肽 T140 含有五个精氨酸残基，是迄今为止开发的最有效的 CXCR4 拮抗剂。在寻找可抑制 HIV 进入的非肽 CXCR4 配体的过程中，我们从 12 个含有 2、3、4、6 或 8 个氨基的线性和支链多胺中合成了三个系列的化合物，并将其取代以产生相应的胍类、双胍类或苯基胍类。测试了所得化合物与 T140 竞争结合哺乳动物细胞上表达的人类 CXCR4 受体的能力。最有效的化合物与 CXCR4 结合的 50% 抑制浓度为 200 nM，而且所有化合物的细胞毒性都很低。然后测试了两个系列的化合物抑制 TZM-bl 细胞感染 X4 和 R5 株 HIV-1 的能力。在低微摩尔浓度下，精胺苯胍和亚精胺苯胍能抑制 X4 株的感染，但不能抑制 R5 株的感染。这些结果支持进一步研究和开发这些化合物作为 HIV 进入抑制剂。

  A corrosion-inhibiting pigment comprising a rare earth element and a valence stabilizer combinded to form a rare earth/valence stabilizer complex. The rare earth element is selected from cerium, terbium, praseodymium, or a combination thereof, and at least one rare earth element is in the tetravalent oxidation state. An inorganic or organic material is used to stabilize the tetravalent rare earth ion to form a compound that is sparingly soluble in water. Specific stabilizers are chosen to control the release rate of tetravalent cerium, terbium, or praseodymium during exposure to water and to tailor the compatibility of the powder when used as a pigment in a chosen binder system. Stabilizers may also modify the processing and handling characteristics of the formed powders. Many rare earth-valence stabilizer combinations are presented that can equal the performance of conventional hexavalent chromium systems.
