A crystal engineering approach has been invoked to design a new series of eight Zn(II) coordination complexes derived from various non‐steroidal anti‐inflammatory drugs (NSAIDs), namely diclofenac (DIC), ibuprofen (IBU), naproxen (NAP), flufenamic acid (FLU) and meclofenamic acid (MEC), and two co‐ligands, namely N‐phenyl‐3‐pyridylamide (3‐Py) and N‐phenyl‐4‐pyridylamide (4‐Py), and Zn(NO3)2 as potential supramolecular gelators. Half of the coordination complexes thus synthesized were able to form aqueous gels (MG‐3‐PyMEC, MG‐3‐PyDIC, MG‐4‐PyNAP and MG‐4‐PyMEC). Single‐crystal structures of all eight complexes revealed that they possessed a gelation‐inducing 1D hydrogen‐bonded network including amide…amide synthon in some cases, which supported strongly the design principles based on which these complexes were synthesized. Interestingly, one such metallogelator complex, namely 3‐PyMEC, showed an intriguing anticancer property against a human breast cancer cell line (MDA‐MB‐231), as revealed by both MTT and cell migration assays.

设计基于NSAID的Zn(II)配位配合物的金属成对剂,用于药物递送应用。

已采用一种晶体工程方法来设计一系列新的八种Zn(II)配位络合物,它们来自各种非甾体类抗炎药(NSAID),即双氯芬酸(DIC),布洛芬(IBU),萘普生(NAP),氟芬那酸(FLU)和甲氯芬那酸(MEC)以及两个共配体,即N-苯基-3-吡啶酰胺(3-Py)和N-苯基-4-吡啶酰胺(4-Py)和Zn(NO 32作为潜在的超分子胶凝剂。这样合成的配位复合物的一半能够形成水凝胶(MG-3-PyMEC,MG-3-PyDIC,MG-4-PyNAP和MG-4-PyMEC)。所有八种配合物的单晶结构都表明它们具有诱导凝胶化的一维氢键网络,其中包括酰胺…酰胺合成子,这在很大程度上支持了合成​​这些配合物的设计原理。有趣的是,MTT和细胞迁移分析均揭示了一种这样的金属成对复合物,即3-PyMEC,对人乳腺癌细胞系(MDA-MB-231)表现出令人感兴趣的抗癌特性。
