A chelating agent having the general formula (I) is provided (I) Metal chelates and constructs for carrying out targeted radionuclide therapy incorporating such chelating agents are provided. Methods of making and using the chelating agent, metal chelates and constructs for carrying out targeted radionuclide therapy, as well as diagnostic and therapeutic methods using such constructs, are provided.
In the solid state, these doublehelices are stacked on top of each other to form long channels filled with water molecules. The 4-methoxy and 4-decyloxy-substituted analogues 1 and 3 have similar dimerization constants, showing that interactions between side chains are not significant between purely aliphatic residues. Consequently, the high stability of the doublehelices formed by 1 and 3 compared
使用收敛方法合成了一系列包含4-烷氧基取代的2,6-二氨基吡啶和2,6-吡啶-二羰基单元的七聚寡酰胺。通过溶液中的1 H NMR光谱在CDCl 3或DMSO- d 6中以各种浓度对这些化合物杂交成双螺旋二聚体进行了研究,并使用X射线晶体学分析以固态对其进行了研究。固态和溶液数据均表明这些化合物遵循相同的杂交方案。在CDCl 3中,其低聚物具有比其在2,6-二氨基吡啶单元上没有烷氧基取代基的相关化合物高得多的二聚常数(至多2000倍)。当4-烷氧基侧链存在于所有吡啶环上时,这种作用的起源可以部分解释为4-烷氧基侧链之间相互作用的结果。例如,4-苄氧基取代的低聚物2具有比4-癸氧基和4-甲氧基取代的类似物1和3更高的二聚化常数。2的晶体结构揭示了围绕双链体的各个角度的苄基侧链之间面对面和边缘面对面的多重芳族-芳族相互作用。在固态下,这些双螺旋彼此叠置以形成充满水分子的长通道。4-甲氧基和4-癸

while facilitating scale up to multi-gram quantities in good yields (63–90%). The previous synthetic methodology was improved through judicious choice of the reducing agent and solvent in the reduction/ring-closing step. Via this platform, we also successfully accessed a mesogenic Bip ligand and herein report initial liquid crystalline properties of this derivative.
Novel synthesis of substituted 4′-hydroxy-2,2′:6′,2″-terpyridines

日期:——
4-Substituted-2,6-diacetylpyridines 2â4 have been
synthesised; by using the Kröhnke-methodology, chalcone and
methylacylpyridinium salts have been reacted to yield
4â²-ethoxy-2,2â²:6â²,2â³-terpyridines 5â7.
These novel 2,2â²:6â²,2â³-terpyridines are functionalised
at C(4â²) and possess substituents at C(4), C(5) and C(6) of both
terminal pyridines, respectively. The ethyl ether protecting group has
been cleaved to obtain
4â²-hydroxy-2,2â²:6â²,2â³-terpyridine 8.
