Quantum chemical treatment of β-sitosterol molecule

Pharmaceutical Biology, 2010
Beta-sitosterol is used as a dietary supplement for lowering plasma cholesterol, and has atherosclerosis preventive, anti-inflammatory, antimicrobial, antipyretic, induced apoptosis, and anticancer effects. In order to understand the effect of the molecule we have investigated the molecule theoretically.

Towards an integrated molecular understanding of plant hormones

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 2787-2826, August 2026.
This review offers a comprehensive overview of the nine plant hormones, delving into their biosynthesis, transport, signaling and crosstalk mechanisms. Because the complexity of plant hormonal control goes beyond these core elements, additional specific features are discussed. Lastly, this review highlights how fundamental insights drive hormonal‐based

β-Secosterol, an Oxyphytosterol Produced Through the Reaction of β-Sitosterol with Ozone, Demonstrates Different Cytotoxic Effects on BRL-3A and HTC Cells

Biomolecules
Sitosterol (Sito) is a phytosterol with bioactive properties, including reducing atherosclerosis risk and anti-inflammatory and antitumoral effects. However, it can be oxidized by reactive oxygen species such as ozone (O3), producing oxyphytosterols with

Barley HvBODYGUARD1 controls cuticular specialisations regulated by SHINE transcription factors

New Phytologist, Volume 251, Issue 3, Page 1188-1208, August 2026.
Cuticle defects result from defective HvBDG1 alleles. Summary Land plants secrete a protective outer cuticular layer with diverse functions. Barley (Hordeum vulgare L.) develops two cuticular specialisations: the β‐diketone rich wax bloom on vegetative tissues and an adherent grain surface which sticks to the hulls, leading to barley's distinctive ...

Long‐Term Salt Exposure Reprograms the Nicotiana tabacum BY‐2 Suspension Proteome and Metabolome Toward Stabilization of the Core Metabolic Pathways, Protein Turnover Machinery Modifications, and Protective Metabolome Adjustments

Plant, Cell &Environment, Volume 49, Issue 8, Page 5849-5865, August 2026.
ABSTRACT In this study, we analyzed a unique Nicotiana tabacum BY‐2 line that was gradually adapted to and subsequently maintained in 190 mM NaCl for over 15 years. Years of continuous high salinity shaped a stable “new homeostasis” in BY‐2 suspension cells. Salt‐adapted cells were smaller and formed tighter clusters. Metabolomics revealed constitutive
