项目摘要
HemoCD, which is composed of a water-soluble iron porphyrin(FeTPPS) and a per-methylated β-cyclodextrin dimer(Py3CD), was attached to poly(acrylic acid) s or gold nano-particles to inhibit glomerular filtration of hemoCD. These modified hemoCDs, which were regarded as the hemoglobin(Hb) and myoglobin(Mb) models, were not excluded in the urine of a rat, suggesting that the modified hemoCDs stay in the blood for a long time. We also tried to apply the present supramolecular system to medicinal chemistry. At first, the removal of endogenous carbon monoxide of a rat was examined by infusing hemoCD solution into the femoral vein. Injected hemoCD was rapidly excreted in the urine in the form of a carbon monoxide adduct, indicating that hemoCD can be used as an antidote of CO poisoning. Meanwhile, hemoCD was unfavorable for the cyanide poisoning. Then we prepared a supramolecule, Im3CD/Fe(III) TPPS complex, which strongly captured the cyanide anion in a rat's body. Since this cyanide remover did not interact with bovine proteins, the Im3CD/Fe(III) TPPS complex was assumed to be better antidote than hydroxocobalamin.
HemoCD由水溶性铁卟啉(FeTPPS)和全甲基化β-环糊精二聚体(Py3CD)组成,附着在聚丙烯酸或金纳米颗粒上以抑制HemoCD的肾小球滤过。被视为血红蛋白(Hb)和肌红蛋白(Mb)模型的hemoCDs不排除在尿液中我们还尝试将现有的超分子系统应用于药物化学,首先,通过将 hemoCD 溶液注入股骨来检查大鼠内源性一氧化碳的去除情况。注射的hemoCD以一氧化碳加合物的形式迅速从尿液中排出,表明hemoCD可以作为CO中毒的解毒剂。然后我们制备了超分子 Im3CD/Fe(III) TPPS 复合物,该复合物捕获了大鼠体内的氰化物阴离子,因为这种氰化物去除剂不与牛蛋白 Im3CD/Fe(III ) 发生相互作用。 TPPS 复合物被认为是比羟钴胺更好的解毒剂。
