    Synthesis, characterization and biological evaluation of tricarbonyl M(i) (M = Re, 99mTc) complexes functionalized with melanin-binding pharmacophores
    摘要:
    旨在评估其作为放射性探针在体内靶向黑色素瘤及其转移的潜力,我们合成了99mTc(I)三碳基络合物(Tc1–Tc8),这些络合物由含吡唑的螯合剂锚定,具有(N3)或(N2O)供体原子组,并用2-氨基乙基二乙胺和4-氨基-N-(2-二乙氨基乙基)苯酰胺作为与黑色素结合的药效团。通过与在宏观水平合成并经过常规分析技术充分表征的Re同类物(Re1–Re8)进行HPLC比较,完成了几种99mTc络合物的化学鉴定。99mTc(I)络合物的生物评估包括测定其与合成黑色素的体外结合,测量在B16F1小鼠黑色素瘤细胞中的细胞摄取,以及在B16F1黑色素瘤小鼠中的生物分布研究。所有测试的络合物均表现出对黑色素的中等到高的体外亲和力,结合百分比在60%到94%之间。与体外测得的较低细胞摄取相符,这些络合物在体内的肿瘤摄取通常相对较低,在4小时后注射的情况下,范围在0.12%到1.69% ID g−1。然而,一些络合物在肿瘤与器官的比率上表现出良好的肿瘤-肌肉和肿瘤-血液比率,分别高达28和5.3。这似乎表明对黑色素瘤组织的一定选择性得以保持,并鼓励进一步优化这类络合物的体外/体内生物特性,以寻找用于黑色素瘤非侵入性成像的新型放射性探针。

  • Rhenium(<scp>v</scp>) oxocomplexes with novel pyrazolyl-based N<sub>4</sub>- and N<sub>3</sub>S-donor chelators

    DOI:10.1039/b611034g

    The novel pyrazolyl-based ligands 3,5-Me2pz(CH2)2NH(CH2)2NH(CH2)2NH2 (1) and pz*(CH2)2NH-Gly-CH2STrit (pz* = pz (8), 3,5-Me2pz (9), 4-(EtOOC)CH2-3,5-Me2pz (10)) were synthesized, and their suitability to stabilize Re(V) oxocomplexes was evaluated using different starting materials, namely (NBu4)[ReOCl4], [ReOCl3(PPh3)2] and trans-[ReO2(py)4]Cl. Compound 1 reacts with trans-[ReO2(py)4]Cl yielding the cationic compound [ReO(OMe)3,5-Me2pz(CH2)2N(CH2)2NH(CH2)2NH2}](BPh4) (11) in a low isolated yield. In contrast, the neutral complexes [ReOpz*(CH2)2NH-Gly-CH2S}] (pz* = pz (12), 3,5-Me2pz (13), 4-(EtOOCCH2)-3,5-Me2pz (14)) were synthesized almost quantitatively by reacting [ReOCl3(PPh3)2] or (NBu4)[ReOCl4] with the trityl-protected chelators 8–10. The X-ray diffraction analysis of 11 and 13 confirmed the tetradentate coordination mode of the respective ancillary ligands. In 11 the monoanionic chelator coordinates to the metal through four nitrogen atoms, while in 13 the chelator is trianionic, coordinating to the metal through three nitrogens and one sulfur atom. Solution NMR studies of 12–14, including two-dimensional NMR techniques (1H COSY and 1H/13C HSQC), confirmed that the N3S coordination mode of the chelators is retained in solution. Unlike 11, complexes 12–14 may be considered relevant in the development of radiopharmaceuticals, as further corroborated by the synthesis of the congener [99mTcOpz(CH2)2-NH-Gly-CH2S}] (12a). This radioactive compound was obtained from 99mTcO4− in aqueous medium, in almost quantitative yield and with high specific activity and radiochemical purity.
    合成了新型的以吡唑基为基础的配体3,5-Me2pz(CH2)2NH( )2NH( )2NH2 (1)和pz*( )2NH-Gly- STrit(pz* = pz (8),3,5-Me2pz (9),4-(EtOOC) -3,5-Me2pz (10)),并评估了它们稳定Re(V)氧化络合物的适用性,使用的起始材料分别为(NBu4)[ReOCl4]、[ReOCl3(PPh3)2] 和 trans-[ReO2(py)4]Cl。化合物1与trans-[ReO2(py)4]Cl反应,生成阳离子化合物[ReO(OMe)3,5-Me2pz( )2N( )2NH( )2NH2}](BPh4) (11),其孤立产率较低。相比之下,几乎定量合成了中性复合物[ReOpz*( )2NH-Gly- S}] (pz* = pz (12),3,5-Me2pz (13),4-(EtOOC )-3,5-Me2pz (14)),通过将[ReOCl3(PPh3)2]或(NBu4)[ReOCl4]与三苯基保护的螯合剂8–10反应。对11和13的X射线衍射分析确认了各自辅助配体的四齿配位模式。在11中,单阴离子螯合剂通过四个氮原子与属配位,而在13中,螯合剂是三阴离子,通过三个氮和一个原子与属配位。对12–14的溶液NMR研究,包括二维NMR技术(1H COSY和1H/13C HSQC),确认了螯合剂的N3S配位模式在溶液中的保留。与11不同,复合物12–14被认为在放射药物开发中具有相关性,进一步通过合成同类物[99mTcOpz( )2-NH-Gly- S}] (12a)得到了印证。该放射性化合物在相中从99mTcO4−获得,几乎定量收率,并具有高特异活性和放射化学纯度。
