Description
技术领域
本发明属于化学和生物技术领域,具体涉及一种光交联分子探针及其制备方法和应用。
背景技术
苯乙酰谷氨酰胺是肠道菌群与人体的共代谢产物,首先由肠道菌将来自饮食的必需氨基酸苯丙氨酸代谢为苯乙酸,后者与谷氨酰胺在人体肝酶作用下形成苯乙酰谷氨酰胺(Nemet I,Saha PP,Gupta N,Zhu W,Romano KA,Skye SM,et al.A CardiovascularDisease-Linked Gut Microbial Metabolite Acts via AdrenergicReceptors.Cell.2020;180(5):862-77e22.doi:10.1016/j.cell.2020.02.016)。研究表明,与人类共生的梭状芽孢杆菌是将苯丙氨酸代谢为苯乙酸的最主要菌属(Dodd D,Spitzer MH,Van Treuren W,Merrill BD,Hryckowian AJ,Higginbottom SK,et al. Agut bacterial pathway metabolizes aromatic amino acids into nine circulatingmetabolites.Nature.2017;551(7682):648-52.doi:10.1038/nature24661),而梭状芽胞杆菌具有减轻炎症、强化肠道屏障的潜在功能(3.Guo P,Zhang K,Ma X,He P.Clostridium species as probiotics:potentials and challenges.J Anim SciBiotechnol. 2020;11:24.doi:10.1186/s40104-019-0402-1)。申请人前期基于大规模人群队列开展代谢组流行病学研究,首次发现高水平的苯乙酰谷氨酰胺降低结直肠癌早期病变的发生风险,表明苯乙酰谷氨酰胺具有抑制结直肠癌前病变的生物学功能。
为开发苯乙酰谷氨酰胺的药用价值,亟需深入阐明该分子与活细胞的作用方式及靶向信号通路。基于点击化学和蛋白质组学技术是研究小分子与蛋白质相互作用的前沿方法,但其依赖于灵敏度高、特异性强,且不影响分子本身功能的小分子探针,目前缺乏可发生点击反应的苯乙酰谷氨酰胺探针。
发明内容
针对现有问题的不足,本发明的第一个目的是提供一种光交联分子探针;本发明的第二个目的是提供上述光交联分子探针的制备方法;本发明的第三个目的是提供上述分子探针的应用。
本发明解决其技术问题采用的技术方案是:
本发明保护一种化合物,其结构式Ⅰ所示:
在苯乙酰谷氨酰胺的苯环上添加光交联和生物正交基团,不影响分子的生物活性,并通过羧基甲酯化提高分子的穿膜能力。
上述式Ⅰ化合物的合成路线如下:
上述化合物的制备方法,包括如下步骤:
(1)将4-氨基苯乙酸乙酯、1-(3-二甲氨基丙基)-3-乙基碳二亚胺盐酸盐、N,N-二异丙基乙胺和2-(3-丁炔基氮二丙啶-3-基)乙酸反应得到中间产物1;
