Chiral symmetry conservation principle.
López-Castillo A. López-Castillo A. Chirality. 2022 Jan;34(1):104-113. doi: 10.1002/chir.23371. Epub 2021 Nov 2. Chirality. 2022. PMID: 34725859
In that case, there are at least two mirrored asymmetric universes if all the chiral properties are strongly correlated. However, if the chiral correlations are weak or nonexistent, there are possibly Many-(Chiral-Symmetry)-Worlds. Alternatively, if our unive …

Chiral Plasmonics and Their Potential for Point-of-Care Biosensing Applications.
Paiva-Marques WA, Reyes Gómez F, Oliveira ON Jr, Mejía-Salazar JR. Paiva-Marques WA, et al. Sensors (Basel). 2020 Feb 10;20(3):944. doi: 10.3390/s20030944. Sensors (Basel). 2020. PMID: 32050725 Free PMC article. Review.
Various experimental techniques are now used to fabricate twisted metallic nanoparticles and metasurfaces, where strongly enhanced chiral near-fields are used to intensify circular dichroism (CD) signals. In this review, state-of-the-art strategies to develop such chira …

3-Nitroatenolol: First Synthesis, Chiral Resolution and Enantiomers' Absolute Configuration.
Sparaco R, Cinque P, Scognamiglio A, Corvino A, Caliendo G, Fiorino F, Magli E, Perissutti E, Santagada V, Severino B, Luciano P, Casertano M, Aiello A, Martins Viegas GY, De Nucci G, Frecentese F. Sparaco R, et al. Molecules. 2024 Apr 3;29(7):1598. doi: 10.3390/molecules29071598. Molecules. 2024. PMID: 38611877 Free PMC article.
As part of our follow-up to this study, herein, we describe the first synthesis of ()-3-nitroatenolol as a probe to evaluate the potential nitration of atenolol by endothelium. Chiral chromatography was used to produce pure enantiomers. By using Riguera's method, which is …

Nuclear magnetic resonance chiral discrimination of fipronil and malathion agrochemicals: A case study.
Iarocz LEB, Silva MS. Iarocz LEB, et al. Chirality. 2021 Sep;33(9):528-534. doi: 10.1002/chir.23336. Epub 2021 Jun 28. Chirality. 2021. PMID: 34184332
For this goal, the commercial agrochemicals fipronil and malathion were employed as active targets due the distinct physicochemical properties. We used the cyclodextrins to evaluate the chiral discrimination in aqueous media and chiral solvent agents to check in org …

Development and validation of an experimental and theoretical method for the chiral discrimination of dinotefuran.
Silva CF, Guimarães L, Borges KB, Nascimento CS Jr. Silva CF, et al. Chirality. 2020 Jan;32(1):53-63. doi: 10.1002/chir.23136. Epub 2019 Nov 6. Chirality. 2020. PMID: 31693253
The novelty of this work was the proposition of a reduced molecular model for the chiral selector amylose-Tris-(3,5-dimethylphenylcarbamate) polysaccharide that was able to adequately describe at the molecular level its interaction with the dinotefuran enantiomers. Besides …
