“…Resveratrol is a polyphenolic microconstituent that is formed in the skin of grapes in response to fungal attack of Botrytis cinerea, behaving like a phytoalexin, and the chemical structure has proven to be a 3,5.4'trihydroxystilbene [15,16,23].…”

The vine contains, in addition to sugars and acids, important amounts of phenolic compounds that accumulate in the solid parts of grapes (clusters, seeds) and skin. The quantity and quality of phenol compounds depends on both the plant and the technology of grape processing. Their high chemical reactivity makes them participate in chemical processes, especially oxido-reduction and condensation. At the same time, these substances have antioxidant qualities that delay the oxidation of wine components. Phenolic compounds also have interesting biological properties. Recent medical research attributed to phenolic compounds from grapes, juice and wines, especially red ones, remarkable sanogenic qualities, due in particular to their antioxidant action when it comes to polyphenols, cardiovascular protection, antiviral, antihistaminic, anti-cancer, anti-inflammatory, etc.This study analyses the management of various maceration-fermentation processes and their influence on the antioxidant capacity of some wines from Iasi vineyard, but also their correlation with specific phenol compounds. The management of winemaking technologies can produce wines with high antioxidant potential, a plus for an increasingly demanding consumer.

The purpose of this research is to synthetize, characterize and thermal degradation of new heterolytic derivates with potential biological properties. The derivates synthesis was done by obtaining new molecules with pyralozone structure which combine two pharmacophore entities: the amidosulfonyl-R1,R2 phenoxyacetil with the 3,5-dimethyl pyrazole which can have potential biological properties. The synthesis stages of the new products are presented as well as the elemental analysis data and IR, 1H-NMR spectral measurements made for elucidating the chemical structures and thermostability study which makes evident the temperature range proper for their use and storage. The obtained results were indicative of a good correlation of the structure with the thermal stability as estimated by means of the initial degradation temperatures as well as with the degradation mechanism by means of the TG-FTIR analysis.

“…The discovery of highly conductive organic charge transfer complexes which are formed from tetrathiafulvalenes derivatives and the acceptor tetracyano-p-quinodimethane has prompted interest in the discovery of new electron donors and acceptors which exhibit similar conductivity. [1][2][3][4] In general, charge-transfer [5][6][7][8][9][10][11][12][13][14][15] or push-pull [16][17][18][19][20] compounds have significant applications in the field of conducting materials. For these reasons heterocyclic compounds -especially those containing sulfur and nitrogen -represent an important resource for the material chemistry [21][22][23][24] and also for medicinal chemistry.…”
