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.
Acute lymphoblastic leukemia is the most common type of cancer in children, accounting for ~30% of cases. [2] However, far more adults than children develop lymphoma and leukemia. Germ cell tumor : Cancers derived from pluripotent cells, most often presenting in the testicle or the ovary ( seminoma and dysgerminoma , respectively).
[23] [24] Mesotrione and sulcotrione are herbicides in this class; a drug, nitisinone, was discovered in the course of developing this class of herbicides. [25] Complementary to mechanism-based classifications, herbicides are often classified according to their chemical structures or motifs. Similar structural types work in similar ways.

After I was diagnosed with stage 3 breast cancer in late 2022 and began researching how to tell my children, I felt like the internet and social workers were reading me bad fortune cookie one-liners.
Mesotrione was introduced in 2002 and like sulcotrione is a triketone, so it is effective on the same weeds and crops, but is more potent, making it more useful in mixes with other herbicides - an important factor for fully controlling weeds and preventing the development of resistance. It has become the biggest selling member of the HPPD class ...
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 .
