Inhibition of Nitrite Reduction with Photosynthetic Inhibitors

Weed Science, 1975
Using a modified in vivo nitrate reductase assay, all photosynthetic inhibitors tested were shown to effectively block light-dependent nitrite reduction in green leaf tissue. Nitrate reduction continued so that nitrite accumulated. Nitrite, vacuum infiltrated into leaf tissue, disappeared linearly with time when incubated in the light.

Synthesis of Pyrazole Derivatives and Their Evaluation as Photosynthetic Electron Transport Inhibitors

Journal of Agricultural and Food Chemistry, 2004
Two series of new pyrazoles, namely six pyrazolo[1,5-a][1,3,5]triazine-2,4-dione and four pyrazolo[1,5-c][1,3,5]thiadiazine-2-one derivatives, were synthesized as potential inhibitors of the photosynthetic electron transport chain at the photosystem II level. The compounds were confirmed by 1H NMR, elemental, and IR analyses.

Replacement of photosynthetic electron transport inhibitors by silicomolybdate

Physiologia Plantarum, 1982
KCN‐treated spinach chloroplasts, their photosystem I being ineffective, exhibit a single reaction site for silicomolybdate. Using this heteropolyanion as electron acceptor, photosynthetic oxygen evolution is partially inhibited by ureas, triazines, or phenylpyridazinone herbicides, their inhibitory effect depending on the concentration of ...

Peculiarities of DNP-INT and DBMIB as inhibitors of the photosynthetic electron transport

Photosynthesis Research, 2023
Inhibitory analysis is a useful tool for studying cytochrome b6f complex in the photosynthetic electron transport chain. Here, we examine the inhibitory efficiency of two widely used inhibitors of the plastoquinol oxidation in the cytochrome b6f complex, namely 2,4-dinitrophenyl ether of 2-iodo-4-nitrothymol (DNP-INT) and 2,5-dibromo-3-methyl-6 ...

The crystal structure of the photosynthetic inhibitors DCMU and DTPU

Biopolymers, 1986
AbstractX‐ray diffraction studies have been carried out on a single crystal of the photosynthetic inhibitors N‐(3,4‐dichlorophenyl)‐N′‐dimethylurea (DCMU) and its newly synthesized spin‐labeled analog N‐(3,4‐dichlorophenyl)‐N′‐(3,3,5,5‐tetramethylpiperidine‐4‐oxyl)‐urea (DTPU).

Relationship between inhibitor binding by chloroplasts and inhibition of photosynthetic electron transport

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1977
The binding of radioactively labelled atrazin, metribuzin and phenmedipham by broken chloroplasts was studied. From the double-reciprocal plots (bound vs. free inhibitors) a high affinity binding reaction is graphically isolated which is related to the inhibition of photosynthetic electron transport.

Furoquinoline alkaloids isolated from Balfourodendron riedelianum as photosynthetic inhibitors in spinach chloroplasts

Journal of Photochemistry and Photobiology B: Biology, 2013
In the search for natural inhibitors of plant growth, we investigate the mechanism of action of the natural furoquinoline alkaloids isolated from Balfourodendron riedelianum (Rutaceae): evolitrine (1), kokusaginine (2), γ-fagarine (3), skimmianine (4) and maculosidine (5) on the photosynthesis light reactions.

Derivatives of diterpen labdane-8α,15-diol as photosynthetic inhibitors in spinach chloroplasts and growth plant inhibitors

Journal of Photochemistry and Photobiology B: Biology, 2013
In a search of new efficient herbicides of natural origin, four derivatives were prepared from labdane-8α,15-diol (1) and 15-O-acetyl-8α-hydroxy labdane (2) isolated from Croton ciliatoglanduliferus. Their inhibitory activity on photosynthetic electron transport on fresh, broken spinach chloroplasts and on the growth of plants were determined ...

Synthesis of Rubrolide Analogues as New Inhibitors of the Photosynthetic Electron Transport Chain

Journal of Agricultural and Food Chemistry, 2012
Many natural products have been used as a model for the development of new drugs and agrochemicals. Following this strategy 11 rubrolide analogues, bearing electron-withdrawing and -donating groups at both benzene rings, were prepared starting from commercially available mucobromic acid.
