Abstract
See also WA 19, 354 and 20, 1795. Two unrelated metabolites of atrazine were isolated from sorghum. Complete N-dealkylation yielded 2-chloro-4,6-diamino-1,3,5-triazine, which no longer inhibited the Hill reaction and cyclic and non-cyclic photophosphorylation in isolated pea chloroplasts. The isolation and identification of the metabolite N,N'-bis(4-ethylamino-6-isopropylamino-1,3,5-triazin-2-yl)cystine gave further support to a previous report that atrazine was metabolized by the glutathione conjugation pathway to its lanthionine conjugate. The isolation of the dimer does not necessarily indicate that this is the form of the metabolite in plants. The N-cysteine monomer may dimerize in vivo during the sequence of reactions leading to the lanthionine conjugate
