- Photobleaching of Compounds of the 5,10,15,20-Tetrakis(m-hydroxyphenyl)-porphyrin Series (m-THPP, m-THPC, and m-THPBC)
-
(Matrix Presented) 5,10,15,20-Tetrakis(m-hydroxyphenyl)porphyrin (m-THPP) yielded novel quinonoid porphyrins upon irradiation in aqueous methanol. True photobleaching was observed for 5,10,15,20-tetrakis(m-hydroxyphenyl)chlorin (m-THPC) and 5,10,15,20-tet

Progress in the photodynamic therapy (PDT) of cancer should benefit from a rationale to predict the most efficient of a series of photosensitizers that strongly absorb light in the phototherapeutic window (650-800 nm) and efficiently generate reactive oxy

- MnO2 instead of quinones as selective oxidant of tetrapyrrolic macrocycles
-
Porphyrins and chlorins were generated through dehydrogenation of the corresponding porphyrinogen and bacteriochlorin precursors using activated manganese dioxide and focused microwave irradiation. The application of this inexpensive heterogeneous oxidant under microwave heating conditions, instead of the quinones usually employed in conventional methodologies, allowed short reaction times, simple overall work-ups and good yields.
