These low molecular weight compounds include indoles, tetrapyrroles, arachidonic acid metabolites, and trp metabolites such as FICZ (6-formylindolo[3,2b]-carbazole), ITE (2-(1H-indol-3-ylcarbonyl)-4-thiazol carboxylic acid methyl ester), indirubin, I3C (indole-3carbinol), and BaP (benzo(a)pyrene) [11, 13-15].

We have previously demonstrated that bilirubin-related tetrapyrroles from blue-green alga Spirulina platensis possess strong antiproliferative effects in pancreatic cancer cells through decrease in mitochondrial superoxide levels and consequent shift to reduction in glutathione redox buffer [25].

Then, the accumulated tetrapyrroles were extracted from the assay mixtures and analyzed by HPLC as described below.
The most commonly tested sensitizers on bacteria have been tricyclic dyes (for example, methylene blue, erythrosine), tetrapyrroles (for example, porphyrins), and furocoumarins (for example, psoralen).
The chromophoric proteins are those attached with linear tetrapyrroles and are called phycobiliproteins, while non-chromophoric proteins are called as colorless linker polypeptides.
