series of novel tertiaryamine derivatives targeting CXCR4 were designed, synthesized, and evaluated. The central benzene ring linker and sidechains were modified and optimized to study the structure–activity relationship. Seven compounds displayed much more potent activity than the reference drug, AMD3100, in both the binding affinity assay and the blocking of Matrigel invasion functional assay. These

different network structures for [AgL 1 ]ClO 4 } n . X-ray single crystalstructure of polymer 1·5H 2 O reveals that the asymmetric unit contains five water molecules that form a two-dimensional hydrogen bonding network with nitrate counter anion. A new conformer of L 1 is observed in the polymeric structure of 1·5H 2 O . Coordination polymers 2 and 2a , both made of [AgL 2 ] + repeating unit, contains
三种一维银(I)配位聚合物[AgL 1] NO 3} n(1),[AgL 2] ClO 4} n(2)和[AgL 2] NO 3} n(2a),其中L 1(吡啶-2-基亚甲基-(4-[(吡啶-2-基亚甲基)-氨基]-甲基}-苄基)-胺)是衍生自α,α'的席夫碱缩合的二室亚氨基吡啶配体-二氨基-对二甲苯和吡啶-2-甲醛和L 2(N-(4-((甲基(吡啶-2-基甲基)氨基)甲基)苄基)-N-甲基(吡啶-2-基)甲胺) L 1是L 1的还原的N-甲基衍生物,已经从配体与各种银盐的反应中分离出来。已知六种不同的L 1构象,它们为[AgL 1] ClO 4} n形成了不同的网络结构。聚合物1·5H 2 O的X射线单晶结构表明,该不对称单元包含5个水分子,这些水分子与硝酸盐抗衡阴离子形成二维氢键网络。在1·5H 2 O的聚合物结构中观察到了新的L 1构象异构体。均由[AgL 2] +重复单元
