Synthesis and Herbicidal Activity of Pyridinyloxyphenoxypropionamides

open access: yesBioscience, Biotechnology, and Biochemistry, 1992
New derivatives of pyridinyloxyphenoxypropionamide were synthesized, which have an unnatural α-amino acid or its decarboxylated structure as amide moieties. Some compounds such as N-(1-metboxycarbonyl-l-tert-butylamino)methyl, N-methoxymethyl and N-hydroxymethyl 2-[4-(3-chloro-5-trifluoromethyl-2-pyridinyloxy)phenoxy] propionamide were found to show ...

Discovery of 3-(1-Amino-2-phenoxyethylidene)-6-methyl-2H-pyran-2,4(3H)-dione Derivatives as Novel Herbicidal Leads

open access: yesAgronomy, 2023
Natural products are one of the resources for discovering novel pesticide leads. Here, by molecular hybridization between the natural enamino diketone skeleton and the reported herbicide lead compound I, a series of 3-(1-aminoethylidene)-6-methyl-2H ...

Studies on the activation of herbicides

open access: yesHilgardia, 1945
Abstract does not appear. First page follows. Introduction Early in 1940 (Chabrolin (1940))4 reported that sodium pentachlorophenate at a concentration of 1.5 per cent killed wild-radish plants. Used at a dosage corresponding to 20 kg per hectare, it was effective as a selective herbicide against certain annual ...

Herbicidal Activity of an Isopropylmalate Dehydrogenase Inhibitor [PDF]

open access: yesPlant Physiology, 1994
Isopropylmalate dehydrogenase (IPMDH) is the third enzyme specific to leucine biosynthesis. It catalyzes the oxidative decarboxylation of 3-isopropylmalate (3-IPM) to 2-ketoisocaproic acid. The partially purified enzyme from pea (Pisum sativum L.) shows a broad pH optimum of 7.8 to 9.1 and has Km values for 3-IPM and NAD of 18 and 40 [mu]M ...

Novel platensimycin derivatives with herbicidal activity [PDF]

open access: yesPest Management Science, 2015
AbstractBACKGROUNDFaced with the need to develop herbicides with different modes of action on account of weed resistance to existing herbicides, the sesquiterpene lactones can be the starting point in the search for new bioactive compounds. Lumisantonin and five novel amides have been evaluated against two monocotyledons and three dicotyledons ...

Herbicidal action of 2-hydroxy-3-alkyl-1,4-naphthoquinones

open access: yes, 2002
The main mode of herbicidal activity of 2-hydroxy-3-alkyl-1,4-naphthoquinones is shown to be inhibition of photosystem II (PSII). The herbicidal and in vitro activities have been measured and correlated with their (Log)octanol/water partition ...
