A membrane-spanning porphyrin has been synthesized by attaching four 3β-hydroxy-5-cholenic acid moieties to α,β,α,β-meso-tetrakis(O-aminophenyl)porphyrin. The resulting steroidal porphyrin, H 2 ChP, and the corresponding metalloporphyrins, MChP, were shown by gel permeation chromatography, 31 P NMR, and differential scanning calorimetry to intercalate into vesicle bilayers. The steroidal porphyrin
通过将四个 3β-羟基-5-胆酸部分连接到 α,β,α,β-内消旋四(O-氨基苯基)卟啉,合成了跨膜卟啉。所得的甾体卟啉 H 2 ChP 和相应的金属卟啉MChP 通过凝胶渗透色谱、 31 P NMR 和差示扫描量热法显示嵌入囊泡双层中。发现甾体卟啉位于双层内定义明确且高度有序的微环境中
