In chemistry, an ionophore (from Greek ion and -phore ' ion carrier ') is a chemical species that reversibly binds ions. [1] Many ionophores are lipid-soluble entities that transport ions across the cell membrane.

2013年11月14日 · 根据改变离子通透性的机制不同,将离子载体分为两种类型:通道形成离子载体 (channel-forming ionophore)和离子运载的离子载体 (ion-carrying ionophore)。 离子载体是一些能够极大提高膜对某些离子通透性的载体分子。 大多数离子载体是细菌产生的抗生素,它们能够杀死某些微生物,其作用机制就是提高了靶细胞膜通透性,使得靶细胞无法维持细胞内离子的正常浓度梯度而死亡,所以离子载体并非是自然状态下存在于膜中的.

离子载体（ionophore）是一些能够极大提高膜对某些 离子 通透性的载体分子。 大多数离子载体是 细菌 产生的抗生素,它们能够杀死某些微生物,其作用机制就是提高了靶细胞膜通透性,使得靶细胞无法维持细胞内离子的正常浓度梯度而死亡,所以离子载体并非是自然状态下存在于膜中的运输蛋白,而是人工用来研究 膜运输蛋白 的一个概念。 根据改变离子通透性的机制不同,将离子载体分为两种类型:通道形成离子载体 (channel-forming ionophore)和离子运载的离子载体 (ion-carrying …

Ionophores are small, lipid-soluble molecules, usually of microbial origin, whose function is to conduct ions across membranes [28,29]. They are facilitated diffusion carriers that transport ions down their electrochemical gradient. Ionophores can be divided into two basic classes: channel formers and mobile carriers (Fig. 19.18) [30].

2020年1月24日 · We herein delineate the construction of an artificial ionophore using a telomeric DNA G-quadruplex (h-TELO) and a lipophilic guanosine (MG). MG stabilizes h-TELO by non-covalent interactions and,...

2025年2月11日 · Calcium Ionophore I，也称为 ETH 1001，是一种中性离子载体，具有极高的 Ca²⁺ 选择性，广泛用于 离子选择电极（ISEs） 及其他对 钙离子检测 要求严格的分析应用。 Calcium ionophore I - selectoprobeCalcium i…

2022年3月1日 · Zinc ionophores increase the intracellular concentration of Zinc ions causing significant biological effects. This review provides, for the first time, an overview of the applications of the main Zinc ionophores in Zinc deficiency, infectious diseases, and in cancer, discussing the pharmacological and coordination properties of the Zinc ionophores.

Ionophores are a diverse class of synthetic and naturally occurring ion transporter compounds which demonstrate both direct and in-direct antimicrobial properties against a broad panel of bacterial, fungal, viral and parasitic pathogens. In addition, ionophores can regulate the host-immune response …

ionophore，英语单词，主要用作名词，作名词时译为“ [生化] 离子载体”。 [1] 1Up removal of the ionophore calcium level returned to normal and NF-AT is exported from the nucleus.除去离子载体后钙离子浓度恢复正常，NF - AT细胞核中排出。 2It's done here experimentally by adding an ionophore that allows calcium to enter the cells from the medium.实验是通过加入允许钙离子从基质进入细胞的离子载体进行的。

Ionophore antibiotics are compounds produced by microorganisms (mainly spore-forming bacteria) ; they act by specifically increasing the ion permeability of the cell membrane. In Vol. I of this series, the then well-known ionophore antibiotics valinomycin (Hunter and...
