杯[4]芳烃化合物0118是一种抑制小鼠肿瘤生长的血管生成抑制剂。虽然0118是半乳糖凝集素-1靶向血管抑制性两亲性肽anginex的拓扑模拟物,但我们尚未证明0118靶向半乳糖凝集素-1。半乳糖凝集素-1参与肿瘤内皮细胞粘附和迁移等病理性疾病,因此是癌症治疗干预的相关靶点。在此,15 N-1H HSQC NMR光谱证明0118确实在远离凝集素的碳水化合物结合位点的位点靶向半乳糖凝集素-1,从而减弱乳糖与凝集素的结合。流式细胞术和凝集试验表明,0118减弱半乳糖凝集素-1的细胞表面聚糖的结合,和细胞增殖的抑制被发现与凝集素的细胞表达。一般而言,我们的数据表明0118靶向半乳糖凝集素-1作为聚糖/碳水化合物结合的变构抑制剂。本工作为杯芳烃化合物0118抗肿瘤药物的临床开发提供了理论依据。
Calix[4]arene compound 0118 is an angiostatic agent that inhibits tumor growth in mice. Although 0118 is a topomimetic of galectin-1-targeting angiostatic amphipathic peptide anginex, we had yet to prove that 0118 targets galectin-1. Galectin-1 is involved in pathological disorders like tumor endothelial cell adhesion and migration and therefore presents a relevant target for therapeutic intervention against cancer. Here, 15N-1H HSQC NMR spectroscopy demonstrates that 0118 indeed targets galectin-1 at a site away from the lectin’s carbohydrate binding site, and thereby attenuates lactose binding to the lectin. Flow cytometry and agglutination assays show that 0118 attenuates binding of galectin-1 to cell surface glycans, and the inhibition of cell proliferation by 0118 is found to be correlated with the cellular expression of the lectin. In general, our data indicate that 0118 targets galectin-1 as an allosteric inhibitor of glycan/carbohydrate binding. This work contributes to the clinical development of anti-tumor calixarene compound 0118.
