Phenazine-1-carboxylic acid (PCA) as a natural product which has significant inhibition effects against many soil-borne fungal phytopathogens in agricultural application and been registered China the fungicide rice sheath blight. In order to find new higher fungicidal activities lead compounds develop eco-friendly agrochemicals, we introduced substructure piperazines also have high biological activity into PCA, designed synthesized series of phenazine-1-carboxylic piperazine derivatives,...
Developing fungicides with phloem mobility that can be applied to leaves control root or vascular pathogens has long been desirable. To achieve this goal, an efficient and economical strategy involves introducing amino acid into the existing highly active parent pesticide molecule. Hence, 12 L-phenazine-1-carboxylic (PCA)-amino conjugates 4a⁻l were designed synthesized via a simple synthetic route. In vitro bioassays results showed all compounds exhibited certain fungicidal activities...
Taking natural product phenazine-1-carboxamide (PCN) as a lead compound, series of novel phenazine-1-carboxylic acid diamide derivatives were designed and synthesised. Their structures confirmed by 1H-NMR HRMS. The bioassays showed that some the target compounds exhibited promising in vitro fungicidal activities, excellent selective herbicidal activities. Particularly, c, h, o s displayed root length inhibition activities against barnyard grass with rate more than 80%. Compound c best...
Ma2 and Ma3 hydrocarbon source rock samples from the Fengcheng Formation in well Maye 1, Mahu Depression, Junggar Basin, were studied using conventional geochemical analysis methods saturated gas chromatography–mass spectrometry. The distribution patterns, abundance, relative content, ratios of different carbon compounds tricyclic terpane rocks fresh-to-mildly-saline (type I), moderately saline II), III) water environments significantly differed. C28–C29TT/C30H C19–C29TT/C30H lowest type I...
Abstract The geological hazard of water–sand inrush is a matter concern for infrastructure construction and resource exploration activities in China, due to the complex interplay between groundwater dynamics stability properties sand particles. This phenomenon characterized by its intensity, hazardous nature, unpredictable behavior. Following comprehensive analysis, this study identifies critical factors influencing processes as fissure width, water stress (waterhead height), in-situ ground...
Tobacco sore shin caused by Rhizoctonia solani Kühn is a major soil-borne fungal disease of tobacco, gradually causing infected stems to become thin and dry, leading great losses China's tobacco industry. Fungicides with phloem mobility are needed for application foliage effectively control root or vascular system pathogens. In this study, phenazine-1-carboxylic acid-valine conjugate (PCA-Val) strong was tested shin. vitro fungicidal activity, systemicity, in vivo efficacy PCA-Val against R....
Abstract Petroleum geologists have debated whether the hydrocarbons from Jurassic coal measures are derived coals, carbonaceous mudstones or coal‐measure in Turpan Basin. Based on geochemistry analysis of 20 crude oils and 40 source rocks Basin, some data been obtained as follows: carbon preference index methylphenanthrene 1.16–1.45 0.28–0.80, ααα C 29 sterane 20S/(20S+20R) ββ/(ββ+αα) 0.44–0.51 0.4–0.54 respectively, which show normal maturity oils; vitrinite reflectance Xishanyao to...
In order to study thermal effect on distribution characteristics of regular sterane in humic coals, a suit 25 coals derived from Kuqa Depression Tarim Basin and Ordos are studied investigate the different maturity, which mainly discusses effect. The results show that C27ααα/C29ααα ratio has linear relationship with Ro (tmax) aromatic hydrocarbon maturity parameters mature high-mature stage. It suggests C27, C29regular steranes will fail reflect original source input high evolutionary On...
