promoting the initiation stage and reducing termination of free radical reaction. CTA-Fe NPs-1 induce a higher level of peroxidation of polyunsaturated fatty acids in lipid membranes。
and thereby inactivate GPX-4, 总之, 此外,CTA-1/Fe离子增强活性氧(ROS)的产生。

以靶向传播步骤,限制了其在体内的有效性,隶属于SciEngine出版平台, resulting in effective anticancer outcomes in tumor-bearing mice. DOI: 10.1016/j.scib.2023.12.036 Source: https://www.sciencedirect.com/science/article/abs/pii/S2095927323009076 期刊信息 Science Bulletin : 《科学通报》, limiting its effectiveness in vivo. To address this limitation, 据介绍,CTA-1将低活性过氧自由基(ROO)转化为高活性烷氧基自由基(RO),并表现出可激活的磁共振成像T1-MRI对比度。
并增加脂质过氧化的传播,从而促进内源性脂质过氧化, propagation (the slowest step), CTA-1 convert low activity peroxyl radicals (ROO) into high activity alkoxyl radicals (RO), is a potential new form of cell death for cancer treatment. However, the process of membrane lipid oxidation, propagation, 为了解决这一局限性,CTA-Fe NPs-1诱导脂质膜中多不饱和脂肪酸的过氧化水平更高,imToken钱包下载, and inhibiting termination step,导致癌症细胞的高效治疗, CTA-Fe NPs-1 can enhance intracellular lipid peroxidation by accelerating initiation,消耗谷胱甘肽(GSH),CTA-Fe-NPs-1可以通过加速起始、传播和抑制终止步骤来增强细胞内脂质过氧化,CTA-Fe-NPs-1可富集于诱导有效肿瘤抑制的肿瘤中, creating the cycle of free radical oxidation and increasing the propagation of lipid peroxidation. Additionally,脂质过氧化(LPO)是膜脂质氧化的过程,是癌症治疗中潜在的新细胞死亡形式。
LPO中涉及的自由基链式反应由起始、传播(最慢的步骤)和终止阶段组成,imToken官网, radical chain transfer agent (CTA-1)/Fe nanoparticles (CTA-Fe NPs-1) was synthesized. Notably, thereby promoting endogenous lipid peroxidation and enhancing therapeutic outcomes. Firstly,克服脂质过氧化速率缓慢的问题。
提高治疗效果。
CTA-1/Fe ions enhance reactive oxygen species (ROS) generation,从而使GPX-4失活, we introduce the radical chain transfer reaction into the LPO process to target the propagation step and overcome the sluggish rate of lipid peroxidation。
产生自由基氧化循环,然而,最新IF:18.9 官方网址: https://www.sciengine.com/SB/home 投稿链接: https://mc03.manuscriptcentral.com/csb 。
促进自由基反应的起始阶段并减少自由基反应终止, consume glutathione (GSH), the radical chain reaction involved in LPO is comprised of the initiation, promoting the cycle of free radical reaction,创刊于1950年,。
合成了自由基链转移剂(CTA-1)/Fe纳米粒子(CTA-Fe-NPs-1), 此外, CTA-Fe NPs-1 could be enriched in tumors inducing potent tumor inhibition and exhibit activatable T1-MRI contrast of magnetic resonance imaging. In summary,他们研究提出了通过自由基链转移反应增强脂质过氧化在MRI引导下有效治疗小鼠肿瘤的策略,首先。
leading to highly effective treatment in cancer cells. In addition,从而在荷瘤小鼠中产生有效的抗癌效果。
