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.

TBC-1 is a chlorophyll-a derivative that acts as a photosensitizer for photodynamic therapy (PDT). It efficiently generates type I ROS and targets the endoplasmic reticulum. TBC-1 demonstrates in vitro biocompatibility and PDT effectiveness under both normoxic and hypoxic conditions.

18:0 Diether PC (1,2-Di-O-octadecyl-sn-glycero-3-phosphocholine) is a glycerophospholipid utilized as a non-hydrolyzable ether lipid in chlorophyll-containing vesicles.

PPO-IN-5 (compound 9) is an herbicide based on PPO inhibitors. Protoporphyrinogen oxidase (PPO) is involved in the biosynthetic pathways of heme and chlorophyll. PPO-IN-5 exhibits tolerance in cereal crops such as wheat, corn, and rice, making it a potential herbicide for wheat fields.

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.

Sonoflora 1, also known as SF1, a PDT photosensitivizer. Chemically, SF1 is an analog of chlorophyll in that its macrocycle backbone is porphyrin-based and the center of the porphyrin ring consists of a metal ion. Preclinical studies showed that SF1 had v

Mg(II) protoporphyrin IX is a key intermediate in chlorophyll biosynthesis in Chlorella and acts as a negative regulator of nuclear photosynthetic gene expression, while serving as an important experimental molecule for dissecting plastid-to-nucleus retrograde signaling pathways in plant and algal biology.

(±)-Jasmonic acid (trans-Jasmonic acid) is a compound found in grapevine inflorescences and fruits with pro-aging activity, inhibiting chlorophyll levels in green and yellowing barley leaf segments, suppressing rice seedling elongation, and participating in biogenic amine chemical coupling through decarboxylation with both aliphatic and aromatic α-amino acids.

Bilirubin oxidase (BOD), a multi-copper oxidase, catalyzes the transformation of bilirubin into biliverdin while reducing molecular oxygen to water. This enzyme plays a role in porphyrin and chlorophyll metabolism and is extensively employed as an oxygen reduction catalyst in biochemical research [1].
