Photosystem II Inhibitor

Photosystem II Inhibitors (4):

Cat. No. Product Name Effect Purity
  • HY-N6715
    Tenuazonic acid
    		Inhibitor 99.58%
    Tenuazonic acid is a nonhost-selective mycotoxin belonging to the tetramic acids family. Tenuazonic acid inhibits protein biosynthesis on ribosomes by suppressing the release of new protein. Tenuazonic acid is acutely toxic, and oral LD50 is set between 81-186 mg/kg in rats and mice. Tenuazonic acid blocks electron transport beyond the primary quinone receptor (QA) by interacting with the D1 protein and is a photosystem II (PSII) inhibitor. In addition, Tenuazonic acid has antiviral effects on measles virus, enterovirus, respiratory virus and so on. Tenuazonic acid has an inhibitory effect on skin cancer.
  • HY-B1876
    Nicosulfuron
    		Inhibitor
    Nicosulfuron is efficient, harmless, antifungal and selective herbicide belonging to the sulfonylurea family. Nicosulfuron is also a photosynthetic system inhibitor and inhibits acetolactate synthase (ALS) enzyme activity. Nicosulfuron degradation by Plectosphaerella cucumerina AR1 is glucose concentration dependent in planktonic lifestyle. Nicosulfuron enhances the glycolysis pathway and tricarboxylic acid cycle to improve the adaptability of sweet maize. Nicosulfuron reduces the synthesis of branched-chain amino acids (BCAAs), which is proming for maize cultivation.
  • HY-N6715R
    Tenuazonic acid (Standard)
    		Inhibitor
    Tenuazonic acid (Standard) is the analytical standard of Tenuazonic acid. This product is intended for research and analytical applications. Tenuazonic acid is a nonhost-selective mycotoxin belonging to the tetramic acids family. Tenuazonic acid inhibits protein biosynthesis on ribosomes by suppressing the release of new protein. Tenuazonic acid is acutely toxic, and oral LD50 is set between 81-186 mg/kg in rats and mice. Tenuazonic acid blocks electron transport beyond the primary quinone receptor (QA) by interacting with the D1 protein and is a photosystem II (PSII) inhibitor. In addition, Tenuazonic acid has antiviral effects on measles virus, enterovirus, respiratory virus and so on. Tenuazonic acid has an inhibitory effect on skin cancer.
  • HY-121242
    Buthidazole
    		Inhibitor
    Buthidazole is a selective herbicide for weed control in corn. Buthidazole inhibits photosynthetic electron transport at two distinct sites in the photosynthetic electron transport chain. The major site of inhibition was on the reducing side of photosystem II. Another site of electron transport inhibition is on the oxidizing side of photosystem II. Buthidazole inhibits corn photosynthesis and prevents starch accumulation in bundle sheath chloroplasts and some ultrastructural disruption of mesophyl chloroplasts of corn plants.
