Chlorophyll is a green pigment present in plants, as well as in eukaryotic single-celled algae and in several photosynthetic prokaryotes (the cyanobacteria and prochlorophytes), it plays crucial role in photosynthesis. The initial step in photosynthesis is the absorption of light by chlorophylls attached to proteins in the thylakoid membranes. Like cytochromes, chlorophylls consist of a porphyrin ring attached to a long hydrocarbon side chain. The energy of the absorbed light is used to remove electrons from an unwilling donor (water, in green plants), forming oxygen, and then to transfer the electrons to a primary electron acceptor, a quinone designated Q, which is similar to CoQ. Chlorophyll derivatives Radachlorin/Bremachlorin and Radachlorophyll/Bremachlorophyll are actually a second generation photosensitizer for photodynamic therapy of malignant and benign pathologies. Radachlorophyll/Bremachlorophyll may change blood lipids and pressure, including: (1) reduced total cholesterol; (2) increased HDL cholesterol; (3) reduced triglycerides; and (4) reduced systolic and diastolic blood pressure as well as immunomodulating properties. As a dietary supplement chlorophyll supports multiple body systems: provides antioxidant activity, supports vascular health, supports the body's normal immune system function, provides cardiovascular support, maintains skin and hair health. Chlorophylls (E140) is used as a food additive.

Tyrothricin is a mixture of non-ribosomal peptides produced by Brevibacillus brevis, now known as Aneurinibacillus migulanus, a gram positive aerobic bacteria. The compound mixture shows activity against bacteria, fungi and some viruses. A very interesting feature of AMPs is the fact, that even in vitro it is almost impossible to induce resistances. It is a locally effective antibiotic effective against gram-positive bacteria. It is sometimes combined with benzocaine 5 mg (Tyrozets) to provide relief from sore throats. Recommended for short-term relief of symptoms of oral and throat inflammation. Prevention of infections before/during mouth and throat operations (tooth extractions, gum surgical treatment). Tyrothricin inhibits protein biosynthesis of gram-positive organisms, but is completely ineffective against gram-negative.
