Inflammations are innate and adaptive immune responses that get instigated in reciprocation to infection. However, if left unchecked, they pose a formidable challenge in clinical settings. In search of user-friendly solutions, our work delineated a rational combinatorial strategy, harnessing chiral orchestration in a triphenylalanine fragment and appending it to δ-amino valeric acid at the N-terminus (hydrogelators I-VIII) such that a potential matrix metalloproteinase-2 (MMP2) inhibitor could be fished out from the design. Our rigorous investigations revealed that from a pool of eight constructs, hydrogelator VIII, with a DLL configuration at the triphenylalanines, displayed excellent MMP2 inhibitory activities , which was further supported by molecular modelling studies. Besides, the β-sheet structured scaffold not only showed substantial antibacterial efficacy against the Gram-positive pathogens , , and but also exhibited proteolytic stability and biocompatibility towards mammalian cells. Furthermore, the scaffold possessed high mechanical strength at physiological pH and mechanical stress-triggered gel-sol-gel transition properties. Finally, the efficacy was evaluated using an air pouch model of acute inflammation in albino mice that certified hydrogelator VIII as a promising anti-inflammatory therapeutic to pave the path for future healthcare management.
炎症是机体针对感染所引发的先天性和适应性免疫反应。然而,如果不加以控制,它们在临床环境中会构成巨大挑战。为了寻找用户友好型解决方案,我们的工作描绘了一种合理的组合策略,利用三苯基丙氨酸片段中的手性编排,并将其连接到N端的δ-氨基戊酸上(水凝胶剂I-VIII),以便从该设计中筛选出潜在的基质金属蛋白酶-2(MMP2)抑制剂。我们的严格研究表明,在八种构建体中,三苯基丙氨酸处具有DLL构型的水凝胶剂VIII表现出优异的MMP2抑制活性,分子建模研究进一步证实了这一点。此外,β-折叠结构支架不仅对革兰氏阳性病原体 、 、 和 具有显著的抗菌效果,而且对哺乳动物细胞表现出蛋白水解稳定性和生物相容性。此外,该支架在生理pH值下具有高机械强度以及机械应力触发的凝胶-溶胶-凝胶转变特性。最后,使用白化小鼠急性炎症的气囊模型评估了其疗效,证实水凝胶剂VIII是一种有前景的抗炎治疗药物,为未来的医疗管理铺平了道路。
