Methods of making such compounds are also disclosed as are methods for the treatment of cancer, various infectious diseases, and abnormal cardiovascular function.
Compounds, systems, and methods for monitoring and treating a surface of a subject
Compounds, systems, and methods are provided for the design and assembly of a non-invasive, analyte sensing dressing that includes a sensor and a matrix. The sensor is capable of detecting analytes such as molecular oxygen. The matrix is at least partially permeable to the analyte. In one version of the dressing, the sensor includes a meso-unsubstituted metallated porphyrin that is sensitive towards oxygen. The metallated porphyrin can be excited when illuminated at a first wavelength, followed by emission of phosphorescence at a second wavelength whose intensity can be used as an indicator for oxygen concentration. The metallated porphyrin can be prepared from a phosphorescent meso-unsubstituted porphyrin having the Formula (I): ##STR00001##
wherein M is a metal, wherein each R is independently an atom or a group of atoms, and wherein at least one R is —O(C)OR′, wherein R′ is optionally substituted alkyl.
