OBJECTIVE Parabens have been commonly used as preservatives in pharmaceutical and cosmetics industries for almost 50 years. These compounds are thermostable, pH-stable and inexpensive and have a wide antimicrobial effect. The antimicrobial activity of parabens in emulsion system is limited by their

To obtain a transparent and effective solution of p-hydroxybenzoic acid esters (parabens), the use of 2-hydroxypropyl-beta-cyclodextrins (2-HP-beta-CyDs) as solubilizers with different degrees of substitution (D.S.) was surveyed. 2-HP-beta-CyDs significantly increased the aqueous solubility of four

Molecular dynamics simulations were performed to obtain information about the conformational behaviour and stabilization of alpha-cyclodextrin (alpha CD) complexes in water. Simulations of p-chlorophenol and p-hydroxybenzoic acid in alpha CD showed that the complex is a very flexible system. The

meso-5,5,7,12,12,14-Hexamethyl-1,4,8,11-tetraazacyclotetradecane as a building block in supramolecular chemistry; salts formed with 2,2-biphenol, 4,4-thiodiphenol, 4,4-sulfonyldiphenol, 3-and 4-hydroxybenzoic acids, 3,5-dihydroxybenzoic acid and phenylphosphonic acid; supramolecular structures in zero, one, two and three dimensions

The Eph receptor tyrosine kinases regulate a variety of physiological and pathological processes not only during development but also in adult organs, and therefore they represent a promising class of drug targets. The EphA4 receptor plays important roles in the inhibition of the regeneration of

Encapsulation of 4-hydroxy-3-methoxy benzoic acid and 4-hydroxy-3,5-dimethoxy benzoic acid with native and modified cyclodextrins.

Inclusion complex formation of 4-hydroxy-3-methoxybenzoic acid (HMBA) and 4-hydroxy-3,5-dimethoxybenzoic acid (HDMBA) with α-CD, β-CD, HP-α-CD and HP-β-CD were studied by absorption, steady state fluorescence, time resolved fluorescence, FT-IR, (1)H NMR and molecular modeling methods. The effect of
