A new synthetic strategy for the preparation of macromolecular MRI contrastagents (CAs) is reported. Four gadolinium(III) complexes bearing either one or two polymerizable methacrylamide groups were synthesized, serving as monomers or crosslinkers for the preparation of water-soluble, polymeric CAs using Reversible Addition–Fragmentation Chain Transfer (RAFT) polymerization. Using this approach, macromolecular
报道了一种制备大分子 MRI 造影剂(CA)的新合成策略。合成了四种带有一个或两个可聚合甲基丙烯酰胺基团的钆( III )络合物,作为单体或交联剂,用于使用可逆加成-断裂链转移(RAFT)聚合制备水溶性聚合CA。使用这种方法,合成了具有不同结构的大分子CA,包括线性、超支化聚合物和凝胶。通过 NMR 弛豫测定法测定了聚合物 CA 的弛豫率,结果表明,与临床使用的 CA、Gd-DOTA 相比,线性聚合物的弛豫率 (60 MHz、310 K) 增加了 5 倍。此外,由Gd( III )交联剂获得的超支化聚合物表现出更高的弛豫率,高达22.8 mM -1 s -1 ,大约比Gd-DOTA(60 MHz,310 K)高8倍。详细的 NMRD 研究表明,超支化聚合物的弛豫度增强是通过限制交联 Gd( III ) 螯合物的局部运动来实现的。 Gd( III ) 单体和交联剂的 RAFT 聚合的多功能性
Design of a New Glutamine–Fipronil Conjugate with α-Amino Acid Function and Its Uptake by <i>A. thaliana</i> Lysine Histidine Transporter 1 (<i>AtLHT1</i>)
Creating novel pesticides with phloem mobility is essential for controlling insects in vascular tissue and root, and conjugating existing pesticides with amino acid is an effective approach. In order to obtain a highly phloem-mobile candidate for efficient pesticides, an electro-neutral l-glutamine–fipronil conjugate (l-GlnF) retaining α-aminoacidfunction was designed and synthesized to fit the substrate
A Gd-III-DOTA-like complex bearing two aliphatic chains on adjacent acetic arms was designed, synthesized, and compared with its analogous monofunctionalized complex. A 1/T-1 NMR relaxometric study of the two amphiphilic complexes incorporated into micelles and liposomes showed an unprecedented relaxivity enhancement for the complex with two lipophilic side arms. This remarkable result, which is attributed to a favorable water exchange rate and increased rigidity of the system resulting from limiting of the local motion of the gadolinium center, represents an important advance in the development of highly efficient nanosystems for MRI applications.
