Hexaflumuron is a chitin synthesis inhibitor used to bait and eliminate termite colonies. Termites are unable to metabolize hexaflumuron and clearance is slow, resulting in up to 100% elimination. Hexaflumuron has also been tested for use with the raisin

Amicarbazone (BAY-MKH3586; BAY314666) is a potent PSII inhibitor, disrupting photosynthetic electron transport by binding to the Qb domain of photosystem II. This broad-spectrum herbicide is effective through foliar and root application, showcasing rapid absorption and translocation. However, its effectiveness can be compromised by common PSII inhibitor resistance. With an IC50 value indicating high potency, amicarbazone leads to chlorosis, stunted growth, tissue necrosis, and death in sensitive plants. Despite these severe effects, it exhibits good selectivity and outperforms atrazine as a herbicide, allowing for its application at lower doses compared to traditional photosynthetic inhibitors.

Tenuazonic acid is a putative nonhost-selective mycotoxin isolated from Alternaria alternate. Tenuazonic acid blocks electron transport beyond primary quinone acceptor (QA) by interacting with D1 protein and it is a broad-spectrum and effective photosyste

Hexazinone is a broad-spectrum herbicide from the triazine family. Hexazinone inhibits photosynthesis through binding to the D-1 quinone protein of the electron transport chain in photosystem II.

Antimalarial agent 17, functioning both as an antimalarial agent and a herbicide, inhibits photosystem II and demonstrates post-emergence herbicidal efficacy comparable to commercial herbicides [1].

Siderin, a Photosystem II inhibitor, effectively impedes ATP synthesis and chloroplast electron transport in photosynthesis within isolated spinach chloroplasts and is utilized in research on plant photosynthesis [1].

Cabraleadiol displays antimycobacterial activity against Mycobacterium tuberculosis, it also is weakly cytotoxic to a breast cancer (BC) cell line. Cabraleadiol inhibits photosystem II (PS II) and induces the appearance of small G band which is related wi

Encecalin and demethylencecalin are major phytotoxic compounds isolated from Helianthella quinquenervis (Hook) A Gray (Asteraceae), they inhibit photosystem II (from water to 2,5-dibromo-3-methyl-6-isopropyl-1,4 p-benzo-quinone).They retard seed germinati

Stigmatellin is an antibiotic derived from the cell mass of the myxobacterium, effective against yeasts (yeasts), filamentous fungi (filamentous fungi), and several Gram-positive bacteria (Gram-positive bacteria). Additionally, it serves as a potent inhibitor of photosynthetic electron (photosynthetic electron) transfer. Stigmatellin utilizes various sugars, polysaccharides, and acids from the citric acid cycle as substrates, inhibiting RNA and protein synthesis. It has two different inhibitory sites: one located on the reducing side of photosystem II and the other at the cytochrome b6 f complex. Stigmatellin holds potential for use in antimicrobial and photosynthesis research.

Spirulina C-phycocyanin is a component of the light-harvesting phycobilisome complex in photosystem II and is a prominently present pigment-protein in Spirulina. Spirulina C-phycocyanin possesses antioxidant, anti-inflammatory, antiplatelet, hepatoprotective, and cholesterol-lowering properties. Spirulina C-phycocyanin can be detected through Raman spectral measurement.

Chlorophyll b is an orally active tetrapyrrole derivative and pigment that can be obtained from photosynthetic organisms such as plants and algae. It acts as a hydrogen donor and enhances glutathione levels. Chlorophyll b possesses antioxidant activity and functionally replaces chlorophyll a in photosystem II to participate in photosynthesis. It reduces DNA damage, chromosome instability, and oxidative stress induced by Cisplatin (HY-17394). Chlorophyll b is primarily used in research on plant photosynthesis mechanisms.
