Introduction Exposure to pesticides has been associated with mental disorders, especially in occupationally exposed populations, such as farmers. This effect has been attributed to the neurotoxic and endocrine-disrupting activity of pesticides, as suggested by experimental studies. Objective To determine the prevalence of common mental disorders and self-reported depression, and analyze their association with the exposure to pesticides in a rural population resident in the municipality of Dom Feliciano, Rio Grande do Sul, where tobacco farming is the main economic activity. Methodology A cross-sectional study evaluating the prevalence of common mental disorders and self-reported depression in a sample of 869 adult individuals resident in Dom Feliciano, between October 2011 and March 2012 was performed. The evaluation of common mental disorders was performed using the Self-Reporting Questionnaire (SRQ-20), setting a cutoff point of 8 for both genders. A standardized questionnaire was used to obtain information on self-reported depression upon prior diagnosis by a health professional, and self-reported exposure to pesticide. In order to evaluate the association between exposure to pesticides and mental disorders, a non-conditional multivariate logistic regression analysis was performed. Results The prevalence of common mental disorders and self-reported depression in the sample population were 23% and 21%, respectively. Among individuals who reported depression, an increase of 73% was observed in the odds of pesticide exposure at an age equal to or less than 15 years. There was a positive association between self-reported pesticide poisoning and common mental disorders (OR = 2.63; 95% CI, 1.62-4.25) as well as self-reported depression (OR = 2.62; 95% CI, 1.63?4.21). Individuals who reported depression had a greater odds of exposure to pyrethroids (OR = 1.80; 95% CI, 1.01?3.21) and aliphatic alcohol (OR = 1.99; 95% CI, 1.04?3.83). An SRQ?20 ? 8 was associated with an approximately seven times higher odds of exposure to aliphatic alcohol (95% CI, 1.73?27.53). Self-reported depression positively correlated with a greater period of exposure to dinitroaniline (OR = 2.20; 95% CI, 1.03?4.70) and sulphonylurea (OR = 4.95; 95% CI, 1.06?23.04). Conclusion The results suggest that exposure to pesticides could be related mental disorders. However, other common risk factors in tobacco farming, the main local economic activity, cannot be excluded.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 1192-07-0 is helpful to your research. Reference of 1192-07-0

Pathogenic Acinetobacter baumannii excrete the siderophore pre-acinetobactin as an iron-scavenging virulence factor. Pre-acinetobactin is a 2,3-dihydroxy-phenyl oxazoline that undergoes pH-dependent isomerization to the isooxazolidinone form acinetobactin in order to expand the pH range for iron acquisition by A. baumannii. In this study we establish important structure-function relationships for the kinetics of isomerization, iron(iii) binding, and siderophore utilization by A. baumannii. We showed that electronic properties of the phenyl oxazoline influence isomerization kinetics and iron(iii) binding. We found that iron(iii) chelation was directly correlated with A. baumannii utilization. Our studies provide important structural and mechanistic insight for understanding how pathogenic A. baumannii uses pre-acinetobactin as a 2-for-1 iron-scavenging siderophore virulence factor.

Several grass and broadleaf weed species around the world have evolved multiple-herbicide resistance at alarmingly increasing rates. Research on the biochemical and molecular resistance mechanisms of multiple-resistant weed populations indicate a prevalence of herbicide metabolism catalyzed by enzyme systems such as cytochrome P450 monooxygenases and glutathione S-transferases and, to a lesser extent, by glucosyl transferases. A symposium was conducted to gain an understanding of the current state of research on metabolic resistance mechanisms in weed species that pose major management problems around the world. These topics, as well as future directions of investigations that were identified in the symposium, are summarized herein. In addition, the latest information on selected topics such as the role of safeners in inducing crop tolerance to herbicides, selectivity to clomazone, glyphosate metabolism in crops and weeds, and bioactivation of natural molecules is reviewed.

This review is focused on the synthesis of isoxazolidines as the core of biologically active compounds having anti-cancer, antiviral, antibacterial and anti-inflammatory properties. The isoxazolidine ring, as mimetic of ribose, has been principally synthesized with high regio-, stereo- and enantioselectivity, applying the methodology of 1,3-dipolar cycloaddition, involving nitrones and alkenes as dipoles and dipolarophiles, respectively. The easy accessibility of this ring by this approach, then, makes this heterocycle, particularly suitable for the synthesis of small molecules useful in the design of new and modified drugs.

The pyrimidine nucleus is a versatile core in the development of antiretroviral agents. Onthis basis, a series of pyrimidine-2,4-diones linked to an isoxazolidine nucleus have been synthesized and tested as nucleoside analogs, endowed with potential anti-HIV (human immunodeficiency virus) activity. Compounds 6a-c, characterized by the presence of an ethereal group at C-3, show HIV reverse transcriptase (RT) inhibitor activity in the nanomolar range as well as HIV-infection inhibitor activity in the low micromolar with no toxicity. In the same context, compound 7b shows only a negligible inhibition of RT HIV.

According to Deslongchamps’ theory of stereoelectronic control, preferentioal cleavage of a tetrahedral intermediate occurs when there are two lone pairs antiperiplanar to the leaving group.For reasons presented (Perrin and Arrhenius, J.Am.Chem.Soc. 1982, 104, 2839), product studies of hydrolysis of cyclic amidines can test this theory, and initial results supported it.However, those results are ambiguous, owing to a mismatch of leaving abilities.We now find that hydrolysis of three six-membered ring amidines bearing matched leaving groups produces predominantly aminoamide, the product of ring cleavage, and only 3-9percent lactam, as expected from the theory.In contrast, hydrolysis of three five- or seven-membered ring amidines produces substantial (ca. 50percent) lactam.Despite attempts to accomodate these results to the theory, it is concluded that there is no general requirement for two lone pairs antiperiplanar to the leaving group and that stereoelectronic control, even in six-membered ring amidines, contributes less than 2 kcal/mol.
