Functionalized fluorine containing phthalocyanine molecules, methods of making, and methods of use in diagnostic applications and disease treatment are disclosed herein. In some embodiments, the fluorine containing phthalocyanine molecules are functionalized with a reactive functional group or at least one cancer-targeting ligand (CTL). The CTL can facilitate more efficient binding and/or internalization to a cancer cell than to a healthy cell. The CTL can inhibit expression of oncoprotein in some embodiments. The pthalocyanine moiety can be used in diagnostic applications, such as fluorescence labeling of a cancer cell, and/or treatment applications, such as catalyzing formation of a reactive oxygen species (ROS) which can contribute to cell death of a cancer cell.
ultraviolet-visible (UV-VIS) and infrared (IR) spectroscopy and their phase transitions were studied by polarizing optical microscopy. Some of these complexes exhibit enantiotropic mesomorphic properties and transition into glass state on cooling. The glass appearance is influenced not only by side chains’ structure, but also by the nature of metal.

moiety diminishes the fluorescence efficiency of 5, relative to 3, but for singlet oxygen (1O2) generation, photochemical hydroperoxidation of β-(−)-citronellol using 5 and 3 occurs with comparable substrate turnover efficiency, albeit at a slower initial triplet oxygen uptake for 5. The bioconjugate 5 is durable; it does not decompose under 1O2 photoreaction conditions. These results suggest a synthetic
使用功能化的不对称氟代-氟代烷基支架F 48 H 7 COOHPcZn(3)制备F 48 H 7 COOPcZn-6-氨基己酸-CTVALPGGYVRVC(5),这是一种可用于光动力疗法的Pep42肽生物共轭物,可以特异性地靶向GRP78伴侣蛋白过度表达,仅定位于某些癌细胞表面。还制备了类似的F 48 H 7 COOHPcCu(4),并阐明了其单晶X射线结构。尽管相对于F 64的非功能化单点配合物而言,位阻降低了PC的支架,在溶液中通过UV-vis光谱没有检测到聚集,对于任一3,4,或5,与缺乏π一致堆叠观察到结晶4。所述6-氨基己酸- Pep42部分减少的荧光效率5,相对于3,但对单重态氧(1 Ò 2)的产生,β的光化学氢过氧化- ( - ) -用香茅醇5和3具有相当的底物转换效率发生,尽管最初的三重态氧气吸收慢了5分钟。生物共轭物5耐用;它在1 O 2光反应条件下不会分解。这些结果表明
