Mesotrione is a selective herbicide used mainly in maize crops. [1] It is a synthetic compound inspired by the natural substance leptospermone found in the bottlebrush tree Callistemon citrinus . It inhibits the enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD) [ 3 ] and is sold under brand names including Callisto and Tenacity.
All of the herbicidal and pharmaceutical triketone HPPD inhibitors including mesotrione (Callisto)(I), [21] sulcotrione (Mikado)(II) [22] and nitisinone (Orfadin)(III) [23] had their common origin in the observation in 1977 by Reed Gray, a biologist at Stauffer Chemical's Western Research Center (WRC) in California, that few weeds emerged under ...
In the mid-1980s, scientists at Stauffer Chemical Company published patents to benzoyl-substituted cyclohexanediones which led to their product mesotrione. [3] This encouraged workers at Rhône-Poulenc to expand their own research into molecules with the same mode of action as these 4-hydroxyphenylpyruvate dioxygenase inhibitors.
Leptospermone was the blueprint for the compound mesotrione which has the trade name Callisto, ... This page was last edited on 21 January 2022, at 22:05 (UTC).
For example, Quinmerac is classified as Group 4/29 (O/L) because it is both an Auxin mimic (Group 4 or O) and inhibits cellulose synthesis (Group 29 or L). [ 9 ] Groups

22-Dihydroergocalciferol is a form of vitamin D, also known as vitamin D 4. [2] It has the systematic name (5Z,7E)-(3S)-9,10-seco-5,7,10(19)-ergostatrien-3-ol. [1] Vitamin D 4 is found in certain mushrooms, being produced from ergosta-5,7-dienol (22,23-dihydroergosterol) instead of ergosterol. [3]
