In the present research, a porous metal–organic framework (MOF) has been synthesized via utilizing 2‐amino[1,1:3,1‐terphenyl]‐4,4,5‐tricarboxylic acid, the amino‐functionalized ligand as the raw material under the solvothermal conditions, and its chemical formula is {[Co3(OH)(ATTCA)2(H2O)]·C2H6NH2·4DMF·H2O} (1). At 273 K, activated MOF (1a) reflects highly selective adsorption of CO2 over CH4 (11.7) and N2 (292.5) and strong CO2‐skeleton interaction. It is significant that the exposure of water vapor does not influence the several carbon dioxide cycles on absorption and release and/or surface area, indicating porous structures have the latent capacity of long‐term use in the wet conditions. In biological research, its therapeutic activity on the myocardial infarction was assessed, and at the same time, the detailed mechanism was investigated. Firstly, real‐time reverse transcription polymerase chain reaction (RT‐PCR) method was conducted to determine the mi‐RNA16 expression levels in the cardiomyocytes. Then, the expression level of the target protein of the mi‐RNA16, XOSC was evaluated with western blotting assay. Furthermore, molecular docking simulation shows that the carboxyl function groups are the origin of the biological activity, which could form multiple binding interactions to the protein.

含多孔Co(II)的金属-有机框架:通过调节miRNA16的表达,选择性捕获CO2和对心肌梗死的临床护理价值

在本研究中,通过利用氨基官能化的配体2-氨基[1,1:3,1-叔苯基] -4,4,5-三羧酸合成了多孔金属-有机骨架(MOF)。溶剂热条件下的原料,其化学式为{[Co 3(OH)(ATTCA)2(H 2 O)]·C 2 H 6 NH 2 ·4DMF·H 2 O}(1)。在273 K下,活化的MOF(1a)反映了CO 2在CH 4(11.7)和N 2(292.5)上的高选择性吸附以及强CO 2骨骼交互。重要的是,水蒸气的暴露不会影响吸收和释放和/或表面积的几个二氧化碳循环,这表明多孔结构具有在潮湿条件下长期使用的潜在能力。在生物学研究中,评估了其对心肌梗塞的治疗活性,同时研究了详细的机制。首先,进行实时逆转录聚合酶链反应(RT-PCR)方法来确定心肌细胞中mi-RNA16的表达水平。然后,用蛋白质印迹分析法评估mi-RNA16,XOSC靶蛋白的表达水平。此外,分子对接模拟表明,羧基官能团是生物活性的起源,
