Pion mass splitting and phase structure in Twisted Mass QCD

, 2004
In the framework of Wilson Chiral Perturbation Theory, we study the effect induced by a twisted Wilson term, as it appears in Twisted Mass QCD (with 2 degenerate quarks). In particular we consider the vacuum orientation and the pion masses.

The Multifaceted Legacy of Thalidomide: Chemistry and Biology Driving Modern Drug Design

ChemMedChem, Volume 21, Issue 7, 14 April 2026.
Thalidomide serves as a molecular nexus linking chemistry and biology: advances in synthesis and structural understanding enable protein degradation technologies, while its immunomodulatory activity underpins anti‐inflammatory and anticancer therapies.

Use of tri-methylated-β-cyclodextrin and sub-2 μm silica particles for enantiomers separation by nano-liquid chromatography

Journal of Chromatography Open
A short capillary column packed with RP18 sub-2 µm particles was investigated for enantioseparation of selected racemic acidic compounds such as nonsteroidal anti-inflammatory drugs (carprofen, cicloprofen, fenoprofen, flurbiprofen, ibuprofen, indoprofen,

Enantioselektive Synthese von (1S,4R)-4-Hydroxycyclopent-2-enyl-acetat durch enzym-katalysierte Veresterung von cis-Cyclopent-2-en-1,4-diol mit Acetanhydrid. Gaschromatographische Untersuchungen zum Reaktionsmechanismus

CHIMIA, 1991
(1S,4R)-4-Hydroxycyclopent-2-enyl-acetate (1), an attractive starting material for the synthesis of prostaglandins, was readily prepared by an enzyme-catalyzed interesterification procedure using acetic anhydride as acylation agent.

Binary mixtures of chiral gases

, 2015
A possible solution of the well known paradox of chiral molecules is based on the idea of spontaneous symmetry breaking. At low pressure the molecules are delocalized between the two minima of a given molecular potential while at higher pressure they ...

PREDICTING CHROMATOGRAPHIC BEHAVIOR OF SEVERAL CHIRAL β-BLOCKERS FROM MOLECULAR STRUCTURE BY QSPR ANALYSIS

Studia Universitatis Babes-Bolyai Chemia, 2016
The chiral HPLC separation parameters of a series of fourteen β-blockers previously performed on four polysaccharide-based chiral stationary phases (CSPs) was evaluated through computational techniques, using a set of 340 molecular descriptors (MD ...
