  Synthesis and Biological Evaluation of New Quinoxaline Derivatives of ICF01012 as Melanoma-Targeting Probes

  摘要：

  The aim of this study was the synthesis and pharmacokinetic selection of a best melanin-targeting ligand for addressing anticancer agents to pigmented melanoma. Seven quinoxaline carboxamide derivatives were synthesized and radiolabeled with iodine-125. Biodistribution studies of compounds [I-125]1a-g performed in melanoma-bearing mice tumor showed significant tumor uptake (range 2.43-5.68%ID/g) within 1 h after i.v. injection. Fast clearance of the radioactivity from the nontarget organs mainly via the urinary system gave high tumor-to-blood and tumor-to-muscle ratios. Given its favorable clearance and high tumor-melanoma uptake at 72 h, amide 1d was the most promising melanoma-targeting ligand in this series. Compound Id will be used as building block for the design of new melanoma-selective drug delivery systems.

  Catellani reaction has received substantial attention because it enables rapid multiple derivatization on aromatics. While using alkyl electrophiles to achieve ortho‐alkylation was one of the earliest applications of the Catellani reaction, ipso‐alkylation‐terminated reactions with β‐H‐containing reactants has not been realized to date. Herein, we report alkylation‐terminated Catellani reaction using alkyl

  Catellani反应已经引起了广泛的关注，因为它能够快速进行芳香族化合物的多重衍生。当使用烷基亲电子来实现邻烷基化是Catellani反应的最早的应用之一，本位与烷基化-封端的反应β -H-含有反应物还没有实现更新。在本文中，我们报道了使用烷基碳霉菌素（缩写为烷基Ge）作为亲核试剂的烷基化终止的Catellani反应。讨论了该反应中烷基Ge和烷基B（OH）2的反应性。该方法可实现与β的有效二烷基化含H的反应物，以前是Catellani反应无法获得的。
