Origin and functional differentiation of (E)-β-ocimene synthases reflect the expansion of monoterpenes in angiosperms.

Journal of Experimental Botany, 2020
The acquisition of new metabolic activities is major force driving evolution. We explored how new functions have arisen diverging terpene synthases (TPSs) from the perspectives of gene family expansion and the evolutionary adaptability of proteins ...

Exploring Linalool‐Based Phytotherapy for Excitatory/Inhibitory Imbalance in Alzheimer's Disease: A Review of Lavender and Cannabis Therapeutic Effects on Sleep, Seizures, and Cognition

Phytotherapy Research, Volume 40, Issue 5, Page 2604-2631, May 2026.
Schematic overview of the proposed neuromodulatory actions of linalool in Alzheimer's disease. Through multi‐target effects on oxidative stress, amyloid aggregation, GABAergic and glutamatergic signaling, linalool may restore excitatory/inhibitory balance.

Specific and Multi‐Product Clade I and Clade IV Sesquiterpene Synthases Contribute to the Psilocybe cubensis Volatilome

ChemBioChem, Volume 27, Issue 8, April 2026.
Five sesquiterpene synthases of Psilocybe cubensis were investigated in vitro and in vivo. CubF is a clade I synthase producing α‐muurolol, whereas clade IV synthases CubG1 and CubG2 produce epi‐isozizaene and β‐duprezianene. Further clade IV synthases CubH and CubI primarily make dauca‐4(11),8‐diene and β‐barbatene, respectively.

Purification and Characterization of an Acyclic Monoterpene Primary Alcohol:NADP+ Oxidoreductase from Catmint (Nepeta racemosa)

Archives of Biochemistry and Biophysics, 1995
A soluble monoterpene primary alcohol:NADP+ oxidoreductase has been purified to apparent homogeneity from leaves of the catmint, Nepeta racemosa. The purified enzyme consisted of two polypeptides, with molecular masses of 42,000 and 40,000 Da, and contained zinc ions.

Catalysis of Aldol Reactions with External Electric Fields in Microfluidic Capacitors: Formation of Organocatalytic Electric Double Layers with Prolinol Ethers and Nitrophenols

ChemistryEurope, Volume 4, Issue 4, April 2026.
Electric‐field catalysis in microfluidic capacitors applied to Hayashi–Jørgenson‐type chemistry reveals mechanisms that operate with field‐directed ion‐pair generation, ion‐pair separation and templated assembly of charged monomers into supramolecular 2D polymers. They are orthogonal to proline chemistry and may serve as guidelines for the discovery of
