合成了La(NO_3)_3与N,N-双(苯并三唑甲基)-[2,2][L(I)]及N-三唑甲基-[2,2][L(Ⅲ)]的配合物单晶,测定了结构,并进行了元素分析、红外光谱及热分析表征。La ̄(3+)离子均与[2,2]环中六个杂原子及三个NO离子配位,稍偏离环平面,三个NO离子分别位于环平面的两侧。初步讨论了[2,2]环所连接支链对配合物结构及其热稳定性的影响。  相似文献

With our interest in (S)-3-aminopyrrolidine derivatives,we further screened inhibition activities of three hit compounds on many other kinases with the results demonstrating that this series of compounds shows better anticancer activities,which might result from the main block of PI3K/Akt signaling pathway and the inhibition of Abelson murine leukemia viral oncogene homolog(ABL) kinase,as well as some epidermal growth factors.Further structure modification demonstrates that benzylsulfonyl group is the necessary functional group contributing to the biological activity that will be helpful to guiding us to optimize these (S)-3-aminopyrrolidine derivatives.  相似文献
