HPPD Inhibitor

Bicyclopyrone is an inhibitor of 4-hydroxyphenylpyruvate dioxygenase (Hpd).

Tembotrione is a herbicide belonging to the HPPD (dioxygenase) inhibitor class with crop selectivity. Tembotrione effectively controls a variety of weeds including broadleaf and gramineous species by disrupting carotenoid synthesis, which leads to chlorophyll degradation and leaf whitening. Mixing Tembotrione with isoxaflutole or adding surfactants optimizes its efficacy and reduces phytotoxicity, with no residual impact on subsequent cruciferous crops, thus helping to increase maize grain yield. The activity of Tembotrione decreases under drought conditions, and under specific conditions (such as double-dose treatment), it may cause reversible yellowing and even yield reduction in crops such as poppy.

HPPD-IN-1 (compound II-3) is a HPPD inhibitor. HPPD-IN-1 shows inhibitory activity of Arabidopsis thaliana HPPD (AtHPPD) with an IC₅₀ value of 0.248 μM, which was superior to that of mesotrione (HY-12853) (0.283 μM) in vitro. HPPD-IN-1 shows excellent herbicidal activity against broadleaf and monocotyledonous weeds.

HPPD-IN-8 is a 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor, with an IC₅₀ of 0.0273 μM and a K_i of 0.226 nM against Arabidopsis thaliana. HPPD-IN-8 can be used for herbicide-related research.

HPPD-IN-6 (Compound IIy) is a HPPD inhibitor with high rice selectivity. HPPD-IN-6 has potent herbicidal activities against Echinochloa crus-galli and Leymus chinensis, including the herbicide-resistant biotypes with EC₅₀s of 19.62-33.26 g of ai/ha. HPPD-IN-6 effectively controls the weeds in rice fields at 90-150 g of ai/ha. HPPD-IN-6 can be used for the development of herbicide.

Isoxaflutole (Standard) is the analytical standard of Isoxaflutole. This product is intended for research and analytical applications. Isoxaflutole (Merlin) is the inhibitor for HPPD that blocks benzoquinone biosynthesis, and results in the bleaching of weeds.

AtHPPD-IN-1 (Compound III-15) is an HPPD inhibitor and herbicide with high safety for peanuts. AtHPPD-IN-1 has IC₅₀ of 12 nM for Arabidopsis thaliana HPPD.

Biscarfentrazone is a HPPD-inhibiting herbicide for wheat fields, which can effectively control ALS-resistant broadleaf weeds and is safe to wheat.

Tembotrione (Standard) is the analytical standard of Tembotrione. This product is intended for research and analytical applications. Tembotrione is a drug that may reduce the productivity of carrots. Tembotrione has the activity of reducing carrot stem mass. Tembotrione can be used to study the total productivity of carrot . Tembotrione is a herbicide belonging to the HPPD (dioxygenase) inhibitor class with crop selectivity. Tembotrione effectively controls a variety of weeds including broadleaf and gramineous species by disrupting carotenoid synthesis, which leads to chlorophyll degradation and leaf whitening. Mixing Tembotrione with isoxaflutole or adding surfactants optimizes its efficacy and reduces phytotoxicity, with no residual impact on subsequent cruciferous crops, thus helping to increase maize grain yield. The activity of Tembotrione decreases under drought conditions, and under specific conditions (such as double-dose treatment), it may cause reversible yellowing and even yield reduction in crops such as poppy.

Fenpyrazone is a 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor as well as a post-emergence herbicide. By inhibiting the activity of HPPD, Fenpyrazone indirectly blocks carotenoid biosynthesis in plants, causing bleaching of new tissues in sensitive plants, followed by necrosis and eventual death. Fenpyrazone is used in studies on controlling annual monocotyledonous and dicotyledonous weeds in summer maize fields.

RPA 202248 is a p-hydroxy phenyl pyruvate dioxygenase (HPPD) inhibitor and degradation product of Isoxaflutole (HY-116139). RPA 202248 demonstrates environmental persistence and undergoes transport through soil matrix and macropores to subsurface drain flow in agricultural field settings.

HPPD-IN-9 is a 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor with an IC₅₀ of 0.21 μM against Arabidopsis thaliana. HPPD-IN-9 acts as a herbicide and exhibits activity against weed species. HPPD-IN-9 is applicable to herbicidal research.
