“…Different amounts of ribavirin dissolved in water or chlorobenzuron dissolved in acetone were added into artificial diet and well mixed before solidification. Then, artificial diets containing a series concentration of ribavirin (2,4,8,16,32,64, and 128 mg/kg) and chlorobenzuron (5,10,20,40,80,160, and 320 mg/kg) were used to feed the third instar larvae. Artificial diets containing acetone or water only were used as the control.…”

“…1,2,4-Triazole derivatives are a group of heterocyclic compounds with multiple biological activities and widely used as pesticides and medicines. − They have been developed to be various kinds of pesticides, such as fungicides (triadimefon, triadimenol, tebuconazole, and propiconazole), herbicides (flucarbazone-sodium, sulfentrazone, and carfentrazone-ethyl), and plant regulators (uniconazole and paclobutrazol). However, only triazophos and azocyclotin are used in insecticides.…”

Ribavirin is an antiviral drug showing high and delayed toxicity to the destructive agricultural pest Spodoptera litura. Larvae fed with artificial diets containing ribavirin could not molt successfully and showed abnormal phenotypes, including cuticle melanization and heavy wrinkle of the newly formed procuticle. RNA-Seq analysis suggested that ribavirin has great negative influence on cuticle. Quantitative real-time-polymerase chain reaction results indicated that ribavirin treatment decreased the expression of key genes in juvenile hormone (JH) biosynthesis (CYP15C1 and JH acid methyltransferase) and most cuticle protein genes, whereas the genes in melanin biosynthesis and bursicon genes were upregulated by ribavirin treatment. These results coincided with the decreased titer of JH I, JH II, and JH III determined by enzyme-linked immunosorbent assay, the much thinner procuticle layer exhibited by histopathological examination, and the cuticle melanization after ribavirin treatment. These results provided a valuable theoretical basis for the creation of green insecticides targeting JH and the development of new insecticide derivatives from 1,2,4-triazole.

Trichloroisocyanuric acid and NaNO2 mediated nitration of indoles under acid-free and Vilsmeier–Haack conditions: synthesis and kinetic study

This study deals with the synthetic and kinetic aspects of trichloroisocyanuric acid (TCCA) and NaNO 2 mediated nitration of indoles in aqueous acetonitrile media under acid-free and Vilsmeier-Haack conditions (using N,N′-dimethyl amides) conditions. Nitration of indoles revealed second order kinetics, with a first order dependence on [indole] and [nitrating agent] ([TCCA]/[NaNO 2 ], [(TCCA-DMF)]/[NaNO 2 ] or [(TCCA-DMA)]/[NaNO 2 ], in which [NaNO 2 ] far excess over other reagents). Reactions followed overall second order kinetics with first order in [reagent] and [indole] under the experimental conditions. Isokinetic temperature (β) values were obtained from Leffler's equation for different kinetic protocols (β = 303 K (TCCA-NaNO 2 ); 303 K (TCCA-DMF)/NaNO 2 ; and 244 K (TCCA-DMA)/NaNO 2 ). These values are the experimental temperature range (303-323 K) indicating that the entropy factors are probably more important in controlling the reaction.
