Antioxidant and Cytotoxic Properties of Piper spp. Volatile Oils That Inhibit Pathogenic Microorganisms

open access: yesFlavour and Fragrance Journal, EarlyView.
The samples were fungicidal against Candida, with MICs ranging from 62.5 to 250 μg/mL, and fungistatic against Penicillium adametzii, Aspergillus flavus and A. niger, with MICs of 1000 μg/mL. The volatile oils of Piper aduncum and Piper marginatum reduced the viability of MDA‐MB231 cells.

GC × GC‐TOF MS and Sensory Profiling of Aroma Compounds in Magnolia Species: Effects of Processing Methods on Volatile Retention in M. wufengensis

open access: yesFlavour and Fragrance Journal, EarlyView.
The first comparative analysis of Magnolia scents reveals that M. wufengensis is characterised by a high aldehyde content, exhibiting a fresh, sweet, and fruity fragrance profile. Furthermore, freeze‐drying preserves 6.7 times more 2‐nonenal compared to shade‐drying, highlighting its superior efficacy in retaining key volatile compounds.

Dietary and biomarker‐guided strategies as supportive measures in the fragile X syndrome

open access: yesFood Biomacromolecules, EarlyView.
Abstract The fragile X syndrome (FXS) is an inherited neurodevelopmental disorder that primarily affects males, often resulting in an IQ below 55, while about two‐thirds of females also experience intellectual disability. Physical features may include an elongated face, prominent ears, finger joint laxity, and enlarged testes in males.

Formal Synthesis of the Akuammiline Alkaloid (±)‐Strictamine via a (4 + 2) Annulation Reaction With a Donor–Acceptor Cyclobutane

open access: yesHelvetica Chimica Acta, EarlyView.
We report a concise formal synthesis of (±)‐strictamine via a silylium‐catalyzed (4 + 2) annulation of a donor–acceptor cyclobutane, achieved in 13 steps from tryptamine. ABSTRACT The akuammiline alkaloids are complex monoterpene indole natural products with a rigid cage‐like architecture and diverse biological activities.
