OBJECTIVE The aim of this study was to empirically generate a responder definition for the treatment of papulopustular rosacea. METHODS A total of 8 multicenter clinical studies on patients with papulopustular facial rosacea were analyzed. All patients were treated with azelaic acid and/or comparator treatments. The severity of rosacea was described by the Investigator Global Assessment (IGA)...

H NMR and C NMR spectrometry (1-dimensional and 2-dimensional) have been used to assign chemical resonances and determine the degrees of branching for polyesters synthesized by the Lewis acid (dibutyltin(IV)oxide)-catalyzed polycondensation of glycerol with either succinic acid (n (aliphatic chain length) = 2), glutaric acid (n = 3) or azelaic acid (n = 7) in quasi-melt solutions with toluene. ...

[structure: see text] The tetraacetylenic compound, (S)-minquartynoic acid (1), is synthesized in seven linear steps and 17% overall yield from commercially available azelaic acid monomethyl ester. The key step is a one-pot three-component Cadiot-Chodkiewicz reaction to construct the tetrayne unit without using either a diyne or a triyne intermediate.

Nowadays, electrospray is becoming a favourable approach for preparing monodispersed nanoparticles. However, this approach is quite recent and requires further works to optimize control over physicochemical properties of its products. This study aimed to determine the possible effects of sonication as a pretreatment to reduce the size of azelaic acid-chitosan particle before using electrospray....

In cell culture, azelaic acid (C9) has been shown to have an antiproliferative and cytotoxic effect on human and murine malignant cutaneous melanocytes. Normal melanocytes are unaffected, as are normal choroidal melanocytes. Here, effects on cell kinetics and ultrastructure of cells of a human choroidal melanoma line have been studied. Cells were exposed to single doses of disodium salts of aze...
