A Look at the Importance of Chirality in Drug Activity: Some Significative Examples

Ceramella, Jessica; Iacopetta, Domenico; Franchini, Angelica; De Luca, Michele; Saturnino, Carmela; Andreu, Inmaculada; Sinicropi, Maria Stefania; Catalano, Alessia (MDPI AG, 2022-11)

[EN] Chirality plays an important role in the development of many pharmaceuticals, being a general property of 'handedness'; nevertheless, a large number of pharmaceuticals are still marketed and administered as racemates. ...
An Na8 Cluster in the Structure of a Novel oxamato-bridged Na'Cu'' three-Dimensional Coordination Polymer

Aukauloo, A.; Ottenwaelder, X.; Ruiz, R.; Journaux, Y.; Pei, Y.; Riviére, E.; Cervera, B.; Muñoz Roca, María Del Carmen (John Wiley & Sons, 1999-01-18)

[EN] The new heterometallic sodium(I)¿copper(II) compound Na4Cu2 (2) · 10.5 H2O (3), where H8[2] stands for N,N',N'',N'''-methanetetrayltetrakismethylenetetrakis(oxamic acid), has been synthesized and its crystal structure ...
Efficient chirality switching in the addition of diethylzinc to aldehydes in the presence of simple chiral alpha-amino amides

Burguete, M.I.; Collado, M.; Escorihuela Fuentes, Jorge; Luis Lafuente, Santiago (Wiley, 2007-09)
Influence of the Framework Topology on the Reactivity of Chiral Pyrrolidine Units Inserted in Different Porous Organosilicas

Llopis-Perez, Sebastian; Velty, Alexandra; DÍAZ MORALES, URBANO MANUEL (MDPI AG, 2019-08)

[EN] Three families of organosiliceous materials with different structuration level, order, and textural properties (non-ordered, M41S, and SBA-15 type materials) were prepared incorporating in their structural framework ...
Role of association in chiral catalysis: from asymmetric synthesis to spin selectivity

Ageeva, A.A.; Khramtsova, E.A.; Magin, I.M.; Purtov, P.A.; Miranda Alonso, Miguel Ángel; Leshina, T.V. (John Wiley & Sons, 2018-12-12)

[EN] The origin of biomolecules in the pre-biological period is still a matter of debate, as is the unclarified nature of the differences in enantiomer properties, especially for the medically important activity of chiral ...
Simulation of left-right asymmetry in heart morphogenesis

Pérez Meroño, Ignacio (Universitat Politècnica de València, 2022-10-11)

[ES] Existen varios estudios sobre la morfogénesis del corazón en el embrión de los vertebrados, y en particular sobre cómo durante el desarrollo del tubo cardíaco se rompe la simetría bilateral dando lugar a una morfogénesis ...
Spin Selectivity in Chiral Linked Systems

Ageeva, A.A.; Khramtsova, E.A.; Magin, I.M.; Richkov, D.A.; Purtov, P.A.; Miranda Alonso, Miguel Ángel; Leshina, T.V. (John Wiley & Sons, 2018-03-12)

[EN] This work has shown spin selectivity in electron transfer (ET) of diastereomers of (R,S)-naproxen-(S)-N-methylpyrrolidine and (R,S)-naproxen-(S)-tryptophan dyads. Photoinduced ET in these dyads is interesting because ...
Supramolecular Transcription of Guanosine Monophosphate into Mesostructured Silica

Bueno Alejo, Carlos Javier; Villaescusa Alonso, Luis Angel; García Bennet, Alfonso E. (Wiley-VCH Verlag, 2014-11-03)

There is large interest in replicating biological supramolecular structures in inorganic materials that are capable of mimicking biological properties. The use of 5- guanosine monophosphate in the presence of Na+ and ...
