CXCR4 is the most common chemokine receptor expressed on the surface of many cancer cell types. In comparison to normal cells, cancer cells overexpress CXCR4, which correlates with cancer cell metastasis, angiogenesis, and tumor growth. CXCR4 antagonists can potentially diminish the viability of cancer cells by interfering with CXCL12-mediated pro-survival signaling and by inhibiting chemotaxis. Herein, we describe a series of CXCR4 antagonists that are derived from (S)-5,6,7,8-tetrahydroquinolin-8-amine that has prevailed in the literature. This series removes the rigidity and chirality of the tetrahydroquinoline providing 2-(aminomethyl)pyridine analogs, which are more readily accessible and exhibit improved liver microsomal stability. The medicinal chemistry strategy and biological properties are described.

1,2,3,4-四氢异喹啉基CXCR4拮抗剂的合成与合成孔径雷达

CXCR4是在许多癌细胞类型的表面表达的最常见的趋化因子受体。与正常细胞相比，癌细胞过度表达CXCR4，这与癌细胞的转移，血管生成和肿瘤的生长有关。CXCR4拮抗剂可能会干扰CXCL12介导的生存前信号并抑制趋化性，从而可能降低癌细胞的生存能力。在本文中，我们描述了一系列CXCR4拮抗剂，它们源自文献中盛行的（S）-5,6,7,8-四氢喹啉-8-胺。该系列去除了四氢喹啉的刚性和手性，从而提供了2-（氨基甲基）吡啶类似物，它们更容易获得并表现出改善的肝微粒体稳定性。描述了药物化学策略和生物学特性。
