描述了一种新的含带卟啉的[2]环烷阴离子宿主系统的合成,结构和阴离子识别特性。链烷的组装是由离散的氯离子模板指导的,该模板与仲芳族供体-受体和配位吡啶-锌的相互作用协同作用。[2] catenane包含一个三维,氢键给体的阴离子结合袋。链烷·氯化物配合物的固态结构分析表明,氯阴离子通过六种会聚的CH·····Cl和NH···Cl氢键相互作用和溶液相1封装在链烷的互锁结合腔内。1 H NMR滴定实验表明,这种互补的氢键排列有助于在DMSO溶液中选择性识别较大的卤化物阴离子上的氯。

The present invention provides erythrocytes or nucleated erythrocyte precursors from animals or patients with at least one S hemoglobin allele which are capable of selectively localizing in tumor vasculature resulting in vaso-occlusion, hemolysis and heme release. A tumoricidal effect is achieved when these cells are administered in before during or after administration of (i) an agent(s) that interferes with degradation of reactive oxygen species, (ii) impairs glucose uptake and/or (iii) chemotherapy. These cells also carry oncolytic viruses, antitumor proteins, multidrug resistant proteins, chemotherapy, monoclonal antibodies, superantigens, superantigen conjugates and fusion proteins, siRNAs, plasmids and non-protein toxins and attenuated tumoricidal bacterial cells specifically into the tumors and induce a tumoricidal effect.
