Plant benzoic acids (BAs) are critical regulators of a plant's interaction with its environment. In addition, innumerable plant-derived pharmacological agents contain benzoyl moieties. Despite the prevalence and import of plant BAs, their biosynthetic pathways are not well-defined. Mounting evidence suggests that BAs are synthesized both directly from shikimate/chorismate and from phenylalanine...
Application of the geometry (HOMA, EN, GEO) and magnetism based (NICS, NICS(1)) indices of aromaticity to optimised geometry of the ring in 12 meta – and 12 para – substituted benzoic acids and their anions by use of DFT computations at B3LYP/6-311+G(d,p) level has shown a very low substituent effect on the π-electron delocalisation. This resembles (qualitatively) the resistance of benzene (and...
Using DFT calculations at various theory levels, quantum-chemical simulations of decomposition paths were performed for a series of nitroalkyl benzoates. It was discovered, that these reactions proceed via polar, but one-step mechanism. It turned out that depending on the nature of the substituent in the ester molecule and on medium polarity, the studied reactions may take place via transition ...
This work demonstrates the influence of catalyst and alkyne nature on regioselectivity rhodium-catalyzed annulation alkoxy-substituted benzoic acids (such as 3-methoxybenzoic, 3,4-dimethoxybenzoic, piperonylic acids) with alkynes. Here, X-ray diffraction DFT calculation data gave evidence that observed is provided by both steric coordination effects methoxy groups. The latter result weak non-co...
Recent studies have shown that the long-term antihypertensive action of soluble epoxide hydrolase inhibition (sEH) in angiotensin-II (AngII)-dependent hypertension might be mediated by the suppression of intrarenal AngII levels. To test this hypothesis, we examined the effects of acute (2 days) and chronic (14 days) sEH inhibition on blood pressure (BP) in transgenic rats with inducible AngII-d...
