The oceans encompass a wide range of habitats and environmental conditions, which host a huge microbial biodiversity. The unique characteristics of several marine systems have driven a variety of biological adaptations, leading to the production of a large spectrum of bioactive molecules. Fungi, fungi-like protists (such as thraustochytrids) and bacteria are among the marine organisms with the ...

Hydrocotyle umbellata L. (Family Araliaceae) populary known as Acaricoba, is indicated in folk medicine for treatment of several inflammatory disorders. The goal of the present study is to evaluate the anti-inflammatory activity of the defatted ethanolic extract (DEE) of the aerial parts using carrageenan-induced rat paw oedema method. The levels of the pro-inflammatory cytokine interl...

substituted schiff bases (hydrazones) 5a-j have been prepared from the starting material 2-chloro pyridine-3-carboxylic acid 1 by a sequence of reactions like reaction with 2-amino-6-nitro benzothiazole (ullamann condensation), thionyl chloride, hydrazine hydrate and different aromatic aldehydes. on cyclocondensation of 5a-j with thioglycolic acid in dry 1,4-dioxane furnished desired compounds ...

Lactic acid bacteria (LAB) can produce a huge amount of bioactive compounds. Since their elective habitat is food, especially dairy but also vegetal food, it is frequent to find bioactive molecules in fermented products. Sometimes these compounds can have adverse effects on human health such as biogenic amines (tyramine and histamine), causing allergies, hypertensive crises, and headache. Howev...

Background: Cyanobacteria have a worldwide distribution in the terrestrial habitats, occurring predominantly on the surface of the soils, stones, rocks, and trees, practically in moist, neutral or alkaline aeries. The unique natural and bioactive compounds from cyanobacteria with various biological activities and an extensive range of chemical classes have a significant capabil...

The coupling reaction of benzoic acid and nicotinic acid hydrazides with N- protected L-amino acids including valine, leucine, phenylalanine, glutamic acid and tyrosine is reported. The target compounds, N-Boc-amino acid-(N;-benzoyl)- and N- Boc-amino acid-(N;-nicotinoyl) hydrazides 5a-5e and 6a-6e were prepared in very high yields and purity using N-[(dimethylamino)-1H-1,2,3-triazolo[4,5-b]pyr...

The contents of ferulic acid, senkyunolide A, butylidenephthalide, ligustilide, and n-butylphthalide were determined by UPLC analytical method; the correlation among the grade, average weight, and content was explored by correlation analysis and analysis of variance (ANOVA); the different commercial grades with average weight and content were revealed by principal component analysis (PCA) and t...

Microencapsulation is a technology that has increasing application in animal nutrition. This provides the possibility to protect sensitive compounds through feed process and storage conditions. Furthermore, of this technique affords increase bioavailability mask unpalatable taste. Different are consider for microencapsulation include certain vitamins, amino acids, fatty organic acids live micro...

or pharmaceutical use of traditional Chinese medicine (TCM) has made it absolutely essential to carry out stringent quality control measures. So far, it is widely accepted that multiple constituents are responsible for the therapeutic effects of TCM, and to ensure its quality, therefore, it is necessary to quantitatively determine the multi-bioactive components of TCM. Over the past decades, va...

We report CH⋯π interactions in aminobenzylnaphthol compounds that bear halogen atoms and amino acid residues (Hirshfeld surface/d e , = chlorine).
