Iptriazopyrid
Based on 1 Customer Validation
Iptriazopyrid is a 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor, with a Ki value of 24.3 nM against Arabidopsis thaliana and 33.3 nM against Oryza sativa. Iptriazopyrid binds to the active pocket of HPPD, occupies the catalytic site, inhibits carotenoid biosynthesis, prevents chloroplast formation, and induces albino and chlorotic symptoms in sensitive plants. Used as a herbicide, Iptriazopyrid can control barnyardgrass when applied alone, and its efficacy does not decrease when mixed with labeled residual herbicides. When Iptriazopyrid is mixed with 2,4-D or triclopyr, its barnyardgrass control effect shows an antagonistic effect. Iptriazopyrid is a triazole carboxamide herbicide that exhibits selectivity for Oryza sativa over Echinochloa crus-galli, and has partial tank-mix compatibility with synthetic auxin herbicides registered for rice.

Biological Activity

HPPD 24.3 |
HPPD 33.3 nM (Ki) |
Iptriazopyrid (0.1-10 μM; 7 days) potently induces chlorosis and inhibits growth in Echinochloa crus-galli with an IC50 of 6.3 g ai ha−1, demonstrating greater phytotoxicity than Mesotrione (HY-12853)[1].
Iptriazopyrid (0.1-10 μM; 7 days) has its phytotoxic effects in Echinochloa crus-galli reversed by Homogentisic acid (HY-113283), confirming iptriazopyrid acts by inhibiting the 4-hydroxyphenylpyruvate dioxygenase pathway[1].
Iptriazopyrid (1000 ng total per plant; 6-48 h) is rapidly metabolized by Oryza sativa into the non-phytotoxic metabolite 656Ox-1, resulting in lower internal iptriazopyrid levels compared to Echinochloa crus-galli, which underlies the compound's selectivity for rice[1].
Iptriazopyrid (2 mM; 1-5 weeks) binds to the catalytic active pocket of both Arabidopsis thaliana HPPD and Oryza sativa HPPD via conserved coordination and hydrophobic interactions, acting as a slow-binding inhibitor of the enzyme[1].
Iptriazopyrid (200-500 nM for AtHPPD; 200-800 nM for OsHPPD; 25 min) potently inhibits Arabidopsis thaliana HPPD with a Ki of 24.3 nM and Oryza sativa HPPD with a Ki of 33.3 nM, showing comparable slow-binding inhibitory activity to Mesotrione[1].
