chlorophyll a

Chlorophyll a is a natural product.

PHYTOL (trans-Phytol) , a diterpene alcohol from chlorophyll widely used as a food additive and in medicinal fields, shows antinociceptive and antioxidant activities as well as anti-inflammatory and antiallergic effects. It is a specific activator of PPARα.

Protoporphyrin IX (PPIX) is a tetrapyrrole that is a metabolic precursor of heme, cytochrome c, and chlorophyll. Protoporphyrin IX has been shown to improve liver function, promote cellular tissue respiration, improve protein and glucose metabolism, and resist complement binding.

Methyl pyropheophorbide-a (MPPa) is a chlorine photosensitizer and a derivative of chlorophyll a. It is photodynamically active, induces apoptosis and inhibits tumor growth, and can be used in photodynamic therapy (PDT) of cancer.

Pheophytin a, a chlorophyll isolated from S. vermiculata extracts, demonstrates antioxidant activity with IC50 values of 200.5 and 137.7 μg mL for SOD and NO, respectively. It also exhibits reducing power (IC50 = 4.2 μg mL) and a cytotoxic effect on the MCF-7 cell line (IC50 = 35.9 μg mL) [1].

Peniviridiol A (compound4) is a chlorophyll derivative isolated from the rhizosphere fungus Penicillium sp. SMU0102.

Methyl pheophorbide-a, a derivative of chlorophyll-a, is a natural compound [1] [2].

Bacteriopheophytin, a photosynthetic pigment found in bacteria, is a demetallated form of bacterial chlorophyll where the magnesium ion at the center is replaced by two hydrogen atoms. It functions as an electron acceptor within the reaction center (RC) of purple bacteria, playing a crucial role in the electron transfer process [1].

Purpurin 18 methyl ester, a derivative of chlorophyll-a, serves as a photosensitizer for photodynamic therapy (PDT), exhibiting the ability to induce cancer cell apoptosis [1].
