    摘要:
    这项研究的目的是开发一种特定的CXCR4靶向放射性碘化剂(125I-或131I-pentixather),用于心肌梗死再灌注(MI/R)大鼠模型中CXCR4表达的单光子发射计算机断层扫描(SPECT)成像。在MI/R后4、12和36小时以及3和7天,用125I-pentixather进行SPECT-CT成像后,通过离体自动放射成像、TTC染色、免疫组织化学以及体内超声心动图和经典的99mTc-MIBI灌注成像对模型进行了验证。SPECT-CT图像显示,梗死心肌(IM)最早在4小时即可清晰可见,并在MI/R后3天达到最大值,而CXCR4上调在MI/R后7天仍可见。在生物分布研究中,观察到IM的高摄取率(在MI/R后4、12和36小时以及3和7天分别为0.99±0.13、1.52±0.29、1.75±0.22、1.94±0.27和0.61±0.14% ID/g),远高于正常心肌。MI/R后3天达到最高摄取率,这与SPECT结果一致。此外,生物分布和SPECT成像中

    趋化因子和趋化因子受体在恶性肿瘤的发生发展中发挥着关键作用,是不可或缺的。作为表达最广泛的趋化因子受体之一,趋化因子(CXC基序)受体4(CXCR4)一直是热门的研究热点。在大多数肿瘤中,CXCR4 表达显着上调。此外,针对CXCR4的综合核素诊断和治疗显示出巨大的潜力。 [ 68 Ga]Ga-pentixafor 是一种靶向 CXCR4 的放射性配体,在体内和体外均表现出对 CXCR4 的强亲和力。然而,[ 177 Lu]Lu-pentixather([ 68 Ga]Ga-pentixafor 的治疗伴侣)需要显着改进以减轻其明显的肝脏生物分布。本研究的目的是合成具有卓越 CXCR4 靶向功能的治疗诊断分子示踪剂。本研究使用高表达CXCR4的Daudi细胞系和弱表达CXCR4的MM.1S细胞系。基于pentixafor的药效团环( -d -Tyr-n-me- d -Orn- l -Arg

    METHODS Cyclic pentapeptides, based on the pentixafor scaffold, were synthesized by a combined solid- and solution-phase peptide synthesis. The CXCR4 receptor affinities of the cold reference compounds were determined in competitive binding assays using CXCR4-expressing Jurkat T - cell leukemia cells and [(125)I]FC131 as the radioligand. RESULTS Metalated pentixafor derivatives with cyclic and acyclic
    背景技术趋化因子受体4(CXCR4)在不同的上皮,间充质和造血癌症中的过表达使CXCR4成为有吸引力的诊断和治疗靶标。但是,用小的基于五环五环的放射性药物靶向CXCR4受体仍然具有挑战性,因为配体-接头-螯合物结构内的微小结构修饰通常会显着影响受体亲和力。基于CXCR4指导的五肽[(68)Ga] pentixafor(环(-D-Tyr-N-Me-D-Orn(AMB-DOTA)-L-Arg-L-2-Nal- (Gly-)),这项研究旨在拓宽适用的(放射性)金属标记的pentixa用于类似物的范围。方法通过固相和溶液相肽合成方法合成了基于pentixafor支架的环状五肽。使用表达CXCR4的Jurkat T细胞白血病细胞和[(125)I] FC131作为放射性配体,在竞争结合试验中确定了冷参考化合物的CXCR4受体亲和力。结果通过固相肽合成法合成了具有环状和非环状螯合剂的金属化戊酯衍生物,并

  • Design, Synthesis, and Functionalization of Dimeric Peptides Targeting Chemokine Receptor CXCR4

    The chemokine receptor CXCR4 is a critical regulator of inflammation and immune surveillance, and it is specifically implicated in cancer metastasis and HIV-1 infection. On the basis of the observation that several of the known antagonists remarkably share a C-2 symmetry element, we constructed symmetric dimers with excellent antagonistic activity using a derivative of a cyclic pentapeptide as monomer. To optimize the binding affinity, we investigated the influence of the distance between the monomers and the pharmacophoric sites in the synthesized constructs. The affinity studies in combination with docking computations support a two-site binding model. In a final step, 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) was introduced as chelator for (radio-)metals, thus allowing to exploit these compounds as a new group of CXCR4-binding peptidic probes for molecular imaging and endoradiotherapeutic purposes. Both the DOTA conjugates and some of their corresponding metal complexes retain good CXCR4 affinity, and one Ga-68 labeled compound was studied as PET tracer.
