Description

General description

Orthosulfamuron is a systemic post-emergence herbicide belonging to the sulfamoylurea class of herbicides. Sulfamoylurea herbicides act through inhibition of branch-chain amino acid biosynthesis in plants. Orthosulfamuron′s specific mode of action is through the inhibition of the plant enzyme, acetolactate synthase, also known as acetohydroxy acid synthase (ALS/AHAS). Inhibition of ALS/AHAS blocks the branched-chain amino acid biosynthesis of valine, leucine, and isoleucine, which are involved in the plant growth process. Orthosulfamuron can be synthesized by reaction of N,N-dimethyl 2-sulfamoylchloride benzcarbamate with 2-amino-4,6-dimethoxypyrimidine in the presence of a base.
